I have a table view and in the cell I put text label that indicates likes count. When I load the app, for example, likes count shows 3. But when I scroll down and then return to the top, those 3 becomes a different number.
I know that it's because of cell reusing. How can I save those numbers for each cell and do not update them on scroll?
Images I\ve cached with AlamofireImage, but I do not know what to do with these text labels
In the cellForRowAtIndexPath, you can use the indexPath to get the correct value back.
I cannot see your code, so if you are just using a number like 1, 2, 3, 4, etc, you can do
Example:
cell.label.text = indexPath.row + 1
or if you're using an array, you could do the following
cell.label.text = array[indexPath.row]
Hope this helps!
The part you are missing is that you need to use the row index to index into your data. Obviously we can't see your code, but it sounds like you are not using this. Generally, you have an array of data, and in cellForRowAtIndexPath, you use the index to lookup the correct data element.
override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath:indexPath) as! MyCell
cell.textLabel.text = "\(likesCount)"
return cell
}
Is your cell a subclass of UITableViewCell?
Give your cell an Identifier (reuse identifier) via IB and then
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
MyTableViewCellSubclass *cell = [tableView dequeueReusableCellWithIdentifier:#"your_identifier"];
// .. your code
}
And redefine the method in your subclass
- (void)prepareForReuse
{
self.yourCountLabel.text = #"0"; // "reset" value
}
You don't prevent it (unless you want to absolutely kill the performance of your application). You embrace it.
In cellForRowAtIndexPath, you get a cell that has been used before for a different. So you change everything that you don't want to be the same as for an unknown other row.

We can get a cell from:
UITableViewCell * cell = [self tableView:tableVie cellForRowAtIndexPath:indexPath]
but it will calling the method cellForRowAtIndexPath:
if I know the cell's tag or indexPath , it's there a way to get the specified cell without to calling cellForRowAtIndexPath:?
Add some reason why I can't call cellForRowAtIndexPath:indexPath
I want to get the cell in the method cellForHeightAtIndexPath to reset the height of each cell. :
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell * cell = [self tableView:tableView cellForRowAtIndexPath:indexPath];
CommentsListResponseDataModel * model = self.liveCommentData[indexPath.row -1];
if (model.viewHeight > 0) {
return model.viewHeight;
} else {
if (model.parentComment) {
CommentParentCell * cc = (CommentParentCell *)cell;
return cc.viewHeight;
} else {
CommentSingleCell * cc = (CommentSingleCell *)cell;
return cc.viewHeight;
}
}
}
}
But this will become a dead loop because it all cellForRowAtIndexPath:indexPath and cellForRowAtIndexPath:indexPath will recall cellForHeightAtIndexPath:indexPath
As of my understanding, you are trying to get the cell object by calling UITableView datasource method. But when you try to do like that then it will be infinite loop call and you will never get the cell object. So in order to get cell object from UITableView, do the following steps.
Declare your UITableView as global to the your ViewController, something like UITableView *_tableView; or #IBOutlet weak UITableView *_tableView;
Then try to call the
//specify the item indexpath
NSIndexPath *_indexPath = [NSIndexPath indexPathForItem:3 inSection:1];
//now try to access cell object by passing cell indexPath
UITableViewCell *_cell = [_tableView cellForRowAtIndexPath:_indexPath];
It seems you want something unrelated to your original question - you want your table view cells to size automatically, depending on content.
What you need to do is:
1. add constraints to your cell - make sure it doesn't have a height constraint, but its content must have Top and Bottom constraints.
2. remove heightForRowAtIndexPath as it will not be necessary
3. set your table view row height to automatic
tableView.rowHeight = UITableViewAutomaticDimension
Now just setup your cell - resize its content to desired height and table cell will automatically be resized
I have an UITableView with ±10 different UITableViewCells to display full information about an object (description cell, photos cell etc.). So when UITableView is loaded, I do not need UITableView cells to be reused. Wouldn't performance be better if I somehow store UITableViewCells and prevent cellForRowAtIndexPath from being called? If so, what is the way to achieve alike behaviour?
First of all, you can not prevent cellForRowAtIndexPath from being called if you are gonna use UITableView. It is a UITableViewDataSource function and it's not an optional one. Otherwise, you won't be able to populate your tableview.
What you can do is use switch case on indexpath.row in cellForRowAtIndexPath and return necessary cell.
You could try by increasing prototype cell in Storyboard. each cell assign new cell identifier and you need to keep array of identifier matching their index with storyboard.
Your cellForRowAtIndexpath will reduced to:
- (UITableViewCell *)tableView:(UITableView *)tableView1 cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView1 dequeueReusableCellWithIdentifier:[cellIdArray objectAtIndex:indexPath.row] forIndexPath:indexPath];
return cell;
}
Note: cellForRowAtIndexpath method will always called. In above case you can put your data in storyboard itself.
Check similar case at https://www.appcoda.com/sidebar-menu-swift/
I have a dynamic list of items, each item could have different teamplate/layout (and height). And one those item types could have an internal list of items to select from, regularly 5-6 rows, each has different height.
If I try to describe it further, in my scenario I have one tableview (#slave) inside tableviewcells (#master-cell) of another tableview (#master). Moreover cells (#slave-cell) in my #slave tableview could have different height as well. So I need to layout my #slave to have #master automatically calc and update its size.
I have the issue with the inner table (#slave). In case of auto-layout, to fit all the cell space, the table will be collapsed unlike UILabel or other controls. So what I need here is to get the projected size of #slave table and set the height of the #slave = content height of the #slave.
I found similar post and it works if all rows have the same height but I'm using custom rows with dynamic height so the tableView.contentSize.Height gives me invalid result (basically just multiply rowNumbers * estimatedRowHeight, you can see it on the screenshot, master item #3 has 4 inner cells). Even after calling #slave.reloadData I couldn't get that size.
What is the proper way to build that kind of UI?
Source code with a test project attached (Xamarin.iOS)
I just ran into the same problem a few days ago,and tried to work it around.
The #master-cell works like a childViewController,it's the delegate datasource of the #slave TableViewController.But you cann't have a childViewController in the UITableViewcell.
Customize UITableViewCell to hold necessary property and acts as #slave TableViewController's delegate datasource,and configure #slave-cell's
height and data.
The real problem is the height for #master-cell,
If your data is simple and static,you can compute the height in advance,and return it in method func tableView(_ tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat of the ViewController.
Otherwise,add a method to #master-cell which return the height for the whole cell when its property is set.And create a proxy #master-cell to compute the height and return it :
override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
let cell = CustomUITableViewCell();
let model = self.getModel(indexPath)
cell.model = model
let height = cell.requiredHeight()
return height;
}
It's complex and expensive,but it works.
I think you do not have need of take UITableView inside UITableView. You can take more than one section in UITableView. And use different cellReuseIdentifier. This way your goal will be achieved.
For such a layout ios provide section in tableview, for master items use SectionView(there is delegate method for sectionView -> in which you can provide view for a section) and as different section may have different type of row so make rows according your need and return them according to section.
Perhaps it is because I do not know the background of you project or what you are trying to accomplish, but tableViews inside of tableVIew cells sounds unnecessarily trivial. Rather than using a master tableView with #slave tableViews, it would be cleaner to just break things out by section in a single tableView as stated in a previous answer. There are UITableViewDelegate methods designed to streamline this for you!
first you have to get string's height then the height have to give in below tableView delegate
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return stringHeight;
}
it is working for me.
I'm using Xcode 8.3.2 and Swift3.1.
I had the same requirement, have tried all, nothing worked for me.
Finally, UIStackView is what worked for me.
In a tableviewcell, I have added a UIStackView(Verticle), keep adding sub cells to that UIStackView. And it automatically increased the cell height.
Check the following to add UIStackView programmatically.
Add views in UIStackView programmatically
If you Use Different Sections and Rows use the below format, its working for me,
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.section == 0) {
return 121;
}
if(indexPath.section==1)
{
return 81;
}
if (indexPath.section%2 == 0 && indexPath.row == 1) {
return 161;
}
if (indexPath.section%2 != 0 && indexPath.row == 0) {
return 81;
}
if (indexPath.section==16 && indexPath.row==0) {
return 161;
}
else
{
return 44;
}
}
i have Template code, different section and row, its each row have different sizes, so i have give this type of code, if you get idea see the above code then its helpful for you,
or
If you change the height for Content text size use the below code, its calculate the content size then change the height(UILabel) size, its working for me
-(CGFloat)tableView:(UITableView*)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
ListModel *model = [ListArray objectAtIndex:indexPath.row];
CGRect labelRect = [model.content boundingRectWithSize:CGSizeMake(tableView.frame.size.width - 90 - 15, 0)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:#{
NSFontAttributeName : [UIFont fontWithName:#"Arial" size:14.0]
}
context:nil];
CGFloat heightOfCell = labelRect.size.height + 60;
if(heightOfCell > 106)
return heightOfCell;
return 106;
}
hope its helpful
yes of course you can have as many prototypes cells as you want for example check this piece of code:
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCellWithIdentifier("TodayWeatherCell", forIndexPath: indexPath) as! SITodayWeatherTableViewCell
cell.setupCell(upCommingWeather)
cell.aboutCityUpdateTableViewClousure = {
self.tableView.reloadData()
}
return cell
}else {
let cell = tableView.dequeueReusableCellWithIdentifier("cityDetailCell", forIndexPath: indexPath) as! SICityDetailTableViewCell
let detail = detailCity[indexPath.row]
cell.setupCityDetail(detail)
return cell
// Configure the cell...
}
}
There are two different cells in one single UITableView.
Hope it helps.
I'm implementing a rich UITableView with customly created UITableViewCell, I show these on the screen in one fashion, but once they go off the screen I want to take a note of that, since the second time they come on I would like them to get displayed in a different manner. Think auto "mark as read" when going off the screen.
I've been looking for some way to detect when a cell goes off the screen (get's deallocated or dequeued or equivalent), preferably in the UITableViewController class to make a quick note of the indexPath.row value, but in the UITableViewCell is equally as good.
I haven't been able to do this in any standard way. Counting the times it appeared seems out of the question as I do multiple reloadData calls on the table.
Anyone any ideas? This seems a bit tricky :)
This is an old question, but in case anyone is looking, in iOS6, a new UITableViewDelegate function was introduced that does just this:
- (void)tableView:(UITableView *)tableView didEndDisplayingCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
It does a great job at telling you whenever a cell is removed, however, it is very thorough and thus if you did a reload cell, even the old cell that's being replaced will trigger this delegate function. In my implementation I simply check to see if the indexPath passed is still within the array tableView.indexPathsForVisibleRows. Something like:
- (void)tableView:(UITableView *)tableView didEndDisplayingCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([tableView.indexPathsForVisibleRows indexOfObject:indexPath] == NSNotFound)
{
// This indeed is an indexPath no longer visible
// Do something to this non-visible cell...
}
}
I think you could use the
- (NSArray *)visibleCells
method for your UITableView. This returns an array of all cells that are visible. You can then mark any data that is "not visible" (i.e. not in this array) in the way you want, such that when you scroll back to it, it has been updated.
Hope that helps
Once UITableViewCell is invisible, it will be removed from UITableView. You may override the method -(void)removeFromSuperView, and do something within the method. At last, do not forget to call [super removeFromSuperView].
The prepareForReuse method on UITableViewCell that Andrey Tarantsov mentions looks good. Putting a couple of NSLogs in there allows you to print out the values of any variables of the cell. Any thoughts as to how this could be set back to the table view controller?
Are you sure a cell going offscreen is exactly what you want to catch? If you want to mark items as read, this does not seem like a proper way to do it. For example, I might scroll though the table really fast, and I would be very surprised if you marked all of the stuff as read.
As for the technical part, simply keep a list of cells that are on screen (cellForRowAtIndexPath should add cells to that list), and in scrollViewDidScroll delegate method check if any of them are no longer visible.
Another possible idea: I remember there is prepareForReuse method on the cell. Not sure when it is called, though.
I know this is a REALLY old question, but in case anyone is looking for an answer for Swift 5:
func tableView(_ tableView: UITableView, didEndDisplaying cell: UITableViewCell, forRowAt indexPath: IndexPath) {
<#code#>
}
I think I would try periodically checking the indexPathsForVisibleRows property of the UITableView. From the largest index path, you can deduce that all previous rows have been scrolled past.
I needed to get some data from the cell as it was scrolled off of the screen. I used #Mr.T's answer however it doesn't state how to get the data.
Say for example the name of the cell class that I'm using is MyCell and it has a data model in it named MyModel with a property of postId. I initially set that info in cellForItem:
var datasource = [MyModel]()
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellId, for: indexPath) as! MyCell
cell.myModel = datasource[indexPath.item] // an individual instance of MyModel from the array
print("cellForItem - indexPath.item: ", indexPath.item) // if the was the very first cell coming on it would print 0
print("postId: ", cell.myModel.postId) // maybe the postId is qwerty
return
}
To get some data from the cell as it is scrolled off of the screen:
func collectionView(_ collectionView: UICollectionView, didEndDisplaying cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
guard let myCell = cell as? MyCell else { return } // You must cast the cell from the method param to your cell type which for me is MyCell
print("didEndDisplayingCell - indexPath.item: ", indexPath.item) // if this was the very first cell scrolling off it should print 0
print("postId: ", myCell.myModel.postId) // the postId should be qwerty
}
The best way to test this is to add a small amount of cells to your collectionView, like first 2 cells, then later on 3 cells, then later on 4 cells. Then just scroll off the very first cell and see what is printed out. Do it for each cell. The indexPath.item and postId should both match for cellForItem and didEndDisplaying.
When you tap a row in a UITableView, the row is highlighted and selected. Is it possible to disable this so tapping a row does nothing?
All you have to do is set the selection style on the UITableViewCell instance using either:
Objective-C:
cell.selectionStyle = UITableViewCellSelectionStyleNone;
or
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
Swift 2:
cell.selectionStyle = UITableViewCellSelectionStyle.None
Swift 3 and 4.x:
cell.selectionStyle = .none
Further, make sure you either don't implement -tableView:didSelectRowAtIndexPath: in your table view delegate or explicitly exclude the cells you want to have no action if you do implement it.
More info here and here
For me, the following worked fine:
tableView.allowsSelection = false
This means didSelectRowAt# simply won't work. That is to say, touching a row of the table, as such, will do absolutely nothing. (And hence, obviously, there will never be a selected-animation.)
(Note that if, on the cells, you have UIButton or any other controls, of course those controls will still work. Any controls you happen to have on the table cell, are totally unrelated to UITableView's ability to allow you to "select a row" using didSelectRowAt#.)
Another point to note is that: This doesn't work when the UITableView is in editing mode. To restrict cell selection in editing mode use the code as below:
tableView.allowsSelectionDuringEditing = false
Because I've read this post recently and it has helped me, I wanted to post another answer to consolidate all of the answers (for posterity).
So, there are actually 5 different answers depending on your desired logic and/or result:
1.To disable the blue highlighting without changing any other interaction of the cell:
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
I use this when I have a UIButton - or some other control(s) - hosted in a UITableViewCell and I want the user to be able to interact with the controls but not the cell itself.
NOTE: As Tony Million noted above, this does NOT prevent tableView:didSelectRowAtIndexPath:. I get around this by simple "if" statements, most often testing for the section and avoiding action for a particular section.
Another way I thought of to test for the tapping of a cell like this is:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// A case was selected, so push into the CaseDetailViewController
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (cell.selectionStyle != UITableViewCellSelectionStyleNone) {
// Handle tap code here
}
}
2.To do this for an entire table, you can apply the above solution to each cell in the table, but you can also do this:
[tableView setAllowsSelection:NO];
In my testing, this still allows controls inside the UITableViewCell to be interactive.
3.To make a cell "read-only", you can simply do this:
[cell setUserInteractionEnabled:NO];
4.To make an entire table "read-only"
[tableView setUserInteractionEnabled:NO];
5.To determine on-the-fly whether to highlight a cell (which according to this answer implicitly includes selection), you can implement the following UITableViewDelegate protocol method:
- (BOOL)tableView:(UITableView *)tableView
shouldHighlightRowAtIndexPath:(NSIndexPath *)indexPath
To sum up what I believe are the correct answers based on my own experience in implementing this:
If you want to disable selection for just some of the cells, use:
cell.userInteractionEnabled = NO;
As well as preventing selection, this also stops tableView:didSelectRowAtIndexPath: being called for the cells that have it set. (Credit goes to Tony Million for this answer, thanks!)
If you have buttons in your cells that need to be clicked, you need to instead:
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
and you also need to ignore any clicks on the cell in - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath.
If you want to disable selection for the whole table, use:
tableView.allowsSelection = NO;
(Credit to Paulo De Barros, thanks!)
As of iOS 6.0, UITableViewDelegate has tableView:shouldHighlightRowAtIndexPath:. (Read about it in the iOS Documentation.)
This method lets you mark specific rows as unhighlightable (and implicitly, unselectable) without having to change a cell's selection style, messing with the cell's event handling with userInteractionEnabled = NO, or any other techniques documented here.
You can also disable selection of row from interface builder itself by choosing NoSelection from the selection option(of UITableView Properties) in inspector pane as shown in the below image
FIXED SOLUTION FOR SWIFT 3
cell.selectionStyle = .none
In your UITableViewCell's XIB in Attribute Inspector set value of Selection to None.
EDIT: for newer Swift it is changed to:
cell.selectionStyle = .none
See this for more info:
https://developer.apple.com/documentation/uikit/uitableviewcell/selectionstyle
In case anyone needs answer for Swift:
cell.selectionStyle = .None
If you want selection to only flash, not remain in the selected state, you can call, in
didSelectRowAtIndexPath
the following
[tableView deselectRowAtIndexPath:indexPath animated:YES];
so it will flash the selected state and revert.
From the UITableViewDelegate Protocol you can use the method willSelectRowAtIndexPath
and return nil if you don't want the row selected.
In the same way the you can use the willDeselectRowAtIndexPath method and return nil if you don't want the row to deselect.
This is what I use ,in cellForRowAtIndexPath write this code.:
cell.selectionStyle = UITableViewCellSelectionStyleNone;
1- All you have to do is set the selection style on the UITableViewCell instance using either:
Objective-C:
cell.selectionStyle = UITableViewCellSelectionStyleNone;
or
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
Swift 2:
cell.selectionStyle = UITableViewCellSelectionStyle.None
Swift 3:
cell.selectionStyle = .none
2 - Don't implement -tableView:didSelectRowAtIndexPath: in your table view delegate or explicitly exclude the cells you want to have no action if you do implement it.
3 - Further,You can also do it from the storyboard. Click the table view cell and in the attributes inspector under Table View Cell, change the drop down next to Selection to None.
4 - You can disable table cell highlight using below code in (iOS) Xcode 9 , Swift 4.0
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "OpenTbCell") as! OpenTbCell
cell.selectionStyle = .none
return cell
}
Objective-C:
Below snippet disable highlighting but it also disable the call to didSelectRowAtIndexPath. So if you are not implementing didSelectRowAtIndexPath then use below method. This should be added when you are creating the table. This will work on buttons and UITextField inside the cell though.
self.tableView.allowsSelection = NO;
Below snippet disable highlighting and it doesn't disable the call to didSelectRowAtIndexPath. Set the selection style of cell to None in cellForRowAtIndexPath
cell.selectionStyle = UITableViewCellSelectionStyleNone;
Below snippet disable everything on the cell. This will disable the interaction to buttons, textfields:
self.tableView.userInteractionEnabled = false;
Swift:
Below are the Swift equivalent of above Objective-C solutions:
Replacement of First Solution
self.tableView.allowsSelection = false
Replacement of Second Solution
cell?.selectionStyle = UITableViewCellSelectionStyle.None
Replacement of Third Solution
self.tableView.userInteractionEnabled = false
Try to type:
cell.selected = NO;
It will deselect your row when needed.
In Swift3 ...
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let r = indexPath.row
print("clicked .. \(r)")
tableView.cellForRow(at: indexPath)?.setSelected(false, animated: true)
}
Swift 3,4 and 5
Better practice, write code in UITableViewCell
For example, you have UITableViewCell with the name MyCell,
In awakeFromNib just write self.selectionStyle = .none
Full example:
class MyCell: UITableViewCell {
override func awakeFromNib() {
super.awakeFromNib()
self.selectionStyle = .none
}
}
I've been battling with this quite profusely too, having a control in my UITableViewCell prohibited the use of userInteractionEnabled property. I have a 3 cell static table for settings, 2 with dates, 1 with an on/off switch. After playing about in Storyboard/IB i've managed to make the bottom one non-selectable, but when you tap it the selection from one of the top rows disappears. Here is a WIP image of my settings UITableView:
If you tap the 3rd row nothing at all happens, the selection will stay on the second row. The functionality is practically a copy of Apple's Calendar app's add event time selection screen.
The code is surprisingly compatible, all the way down to IOS2 =/:
- (NSIndexPath *)tableView: (UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row == 2) {
return nil;
}
return indexPath;
}
This works in conjunction with setting the selection style to none, so the cell doesn't flicker on touch down events
We can write code like
cell.selectionStyle = UITableViewCellSelectionStyleNone;
but when we have custom cell xib above line give warning at that time for
custom cell xib
we need to set selection style None from the interface builder
You just have to put this code into cellForRowAtIndexPath
To disable the cell's selection property:(While tapping the cell).
cell.selectionStyle = UITableViewCellSelectionStyle.None
From UITableViewDataSource Protocol, inside method cellForRowAt add:
let cell = tableView.dequeueReusableCell(withIdentifier: "YOUR_CELL_IDENTIFIER", for: indexPath)
cell.selectionStyle = .none
return cell
OR
You can goto Storyboard > Select Cell > Identity Inspector > Selection and select none from dropdown.
I am using this, which works for me.
cell?.selectionStyle = UITableViewCellSelectionStyle.None
try this
cell.selectionStyle = UITableViewCellSelectionStyleNone;
and
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
and you can also set selection style using interfacebuilder.
Directly disable highlighting of TableViewCell into storyboard
While this is the best and easiest solution to prevent a row from showing the highlight during selection
cell.selectionStyle = UITableViewCellSelectionStyleNone;
I'd like to also suggest that it's occasionally useful to briefly show that the row has been selected and then turning it off. This alerts the users with a confirmation of what they intended to select:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:NO];
...
}
To disable the highlighting of the UItableviewcell
cell.selectionStyle = UITableViewCellSelectionStyleNone;
And should not allow the user to interact with the cell.
cell.userInteractionEnabled = NO;
You Can also set the background color to Clear to achieve the same effect as UITableViewCellSelectionStyleNone, in case you don't want to/ can't use UITableViewCellSelectionStyleNone.
You would use code like the following:
UIView *backgroundColorView = [[UIView alloc] init];
backgroundColorView.backgroundColor = [UIColor clearColor];
backgroundColorView.layer.masksToBounds = YES;
[cell setSelectedBackgroundView: backgroundColorView];
This may degrade your performance as your adding an extra colored view to each cell.
You can also do it from the storyboard. Click the table view cell and in the attributes inspector under Table View Cell, change the drop down next to Selection to None.
You can use :
cell.selectionStyle = UITableViewCellSelectionStyleNone;
in the cell for row at index path method of your UITableView.
Also you can use :
[tableView deselectRowAtIndexPath:indexPath animated:NO];
in the tableview didselectrowatindexpath method.
You can use this
cell.selectionStyle = UITableViewCellSelectionStyleNone;
You can use ....
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
