I am using cells with two heights based on some status.
When start is StatusAwarded it shows full cell else it will show a part of it.
Here is the code to achieve this.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
SomeClass *someClass = dataArray[indexPath.row];
if (someClass.status == StatusAwarded) {
return 252.0f;
}
return 110.0f;
}
It works all fine but when it is in edit mode, it has this issue as shown below.
I am having effect like this while editing (Deleting).
Question:
Why is this happening? How to fix this?
Note: Clip Subviews is set to YES
Try to enable Clip Subviews in Interface Builder / Storyboard.
You're not reloading the other cells, try:
[tableViewAdvancedBookings reloadRowsAtIndexPaths:[indexPathsToExpand allObjects] withRowAnimation:UITableViewRowAnimationAutomatic];
instead of:
[tableViewAdvancedBookings reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
which only reload the currect selected cell..
or maybe try reloading the whole table like:
[tableView reloadData];
and see what happen.. hope i've help, for some reason.. Good night, Cheers..

Hi i have been searching around to find a way to remove a static cell with animation but i have not found a solution to the problem.
I have also tried: [tableView deleteRowsAtIndexPaths:[self.taskArray objectAtIndex:indexPath.row] withRowAnimation:UITableViewRowAnimationFade];
but no success.
You need to hide cell before it is shown, in UITableViewDelegate's tableView:willDisplayCell:forRowAtIndexPath: method. This is the last method in your control where you can manipulate the cell display. It does not remove the space the cell takes, so another thing you can try is to set cell row's height to 0 using the tableView:heightForRowAtIndexPath: method of the same protocol.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [super tableView:tableView cellForRowAtIndexPath:indexPath];
if (yourCell) {
return 0;
} else {
return [super tableView:tableView heightForRowAtIndexPath:indexPath];
}
}
As your tableview is static, you cannot use deleteRowsAtIndexPath. The best option would probably be to migrate your data into a dataSource method for the tableview.
If this is impossible, then this answer ("UITableView set to static cells. Is it possible to hide some of the cells programmatically?") gives that the best method is to use the third party library
StaticDataTableViewController 2.0 (https://github.com/xelvenone/StaticDataTableViewController).
Otherwise you have to use the somewhat hacky method of changing the row height to 0.
I have UITableView.When view load i want to show the tableview without section.Also i have only one section of the tableview.I have referred much coding.But i am not satisfied with that.I have applied following coding in viewDidLoad.
[tableviewSetting deleteSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationFade];
self.editing = YES;
Even i applied above coding in viewDidLoad,it does not change anything.So if you guys anyone help for me,it will be better.Please tell me the explanation of above coding.
Few questions
Are you using group table?
Its iOS 7?
If you need to remove unrequited space of section from top (normally it should not be there), then try following code. It might work
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
return 0.01;
}
When a user taps a button in one of my rows I am updating the underlying model for that row and then calling reloadRowsAtIndexPaths for the given row (i.e. single row reload).
- (IBAction)handleCompleteTouchEvent:(UIButton *)sender {
NSIndexPath *indexPath = [self.tableView indexPathForView:sender];
id item = [self dataForIndexPath:indexPath];
if ([item respondsToSelector:#selector(completed)]) {
// toogle completed value
BOOL completed = ![[item valueForKey:#"completed"] boolValue];
[item setValue:[NSNumber numberWithBool:completed] forKey:#"completed"];
[self.tableView beginUpdates];
[self.tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationNone];
[self.tableView endUpdates];
}
}
The problem is that the table view bounces back to the top of the section after making this call. How can I prevent this from occurring and keep the scroll position where it is?
Ah Ha! I found the problem and am going to answer my own question for the poor soul who runs into this issue in the future.
All of my cells have variable height so I was using the new iOS7 method in UITableViewDelegate thinking it might speed up render time (not that I really needed it):
- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath;
Anyway, implementing this method has the evil side effect of causing the table to bounce to the top of the section when calling:
[self.tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationNone];
To solve the bounce problem I just removed the override of that estimatedHeightForRowAtIndexPath method and now everything works as it should. Happy at last.
This did the trick for me.
UIView.setAnimationsEnabled(false)
tableView.reloadRows(at: [...], with: .none)
UIView.setAnimationsEnabled(true)
Swift 4.2
This can work anywhere you want to remove animation.
During reload of table , table section or any row
UIView.performWithoutAnimation({
cell.configureSelection(isSelected: true)
tableView.reloadSections([1], with: .none)
tableView.allowsSelection = false
})
You should be able to do what you are trying to do by changing the cell contents directly. For example, if you are using the base UITableViewCell class and the data in your model is a NSString which you show in the table view cell, you can do the following (after you change your data model) instead of calling reloadRowsAtIndexPaths:
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
UILabel *label = [cell textLabel];
label.text = #"New Value";
If you are using a custom subclass of UITableViewCell, it's roughly the same except for accessing the views of the cell will need to be done through the contentView property.
It may be possible to put the cell in it's own section and call reload section:
[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:1] withRowAnimation:UITableViewRowAnimationFade];
this appears to fix the issue partially. Not the cleanest way but it may work for you.
In my similar case, I had to tweak the implementation of method
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
...
}
where my heights were being reset. So, instead of resetting height for every cell I updated only the effected cells for reloadRowsAtIndexPaths call.
If you know the minimum height of your cell, you must specify that while setting estimatedRowHeight. I was setting it to 1 as I have read before somewhere that any value above 0 would suffice the purpose, but it was the culprit.
When I set it to 44, which was the minimum height my cell could have, all went fine.
Dynamic heights were also working fine, no issues with this fix.
To build off xsee's answer -
I had set the Estimate in interface builder to "automatic". I changed this to another number and it started working. I kept Row Height to automatic.
I had the same issue. I ended up just calling tableView.reloadData() instead after updating my data / cell and it didn't bounce back to the top / data was updated in place - FYI
This solved this issue for me with Swift 5 / iOS 14:
UIView.performWithoutAnimation({
self.tableView.reloadRows(at: [self.idxTouched], with: .none)
})
I gave a look on QuizUp and I would like to make a similar menu on my iphone application.
I don't understand how they made the menu. It looks like a table view controller, but a new menu appears under the cell when the user tap on it.
Can someone give me some clues. Is it possible to do that with the native iOS SDK ? How ?
According to the developer of Quiz Up, the app was made using Cocos2D.
That being said, it is also possible to do it using a UITableView. Theres just a couple things you would need to do. The first is get tableView:heightForRowAtIndexPath: to return a different height for the row(s) you want to be expanded. For example, if you only want one row expanded you could use the following.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([[tableView indexPathForSelectedRow] isEqual:indexPath]) {
return 100.0f;
}
return 44.0f;
}
Then what you need to do is call beginUpdates and endUpdates on your tableview whenever you want the height to update.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView beginUpdates];
[tableView endUpdates];
}
After that, you just need to layout your cell so that when it's expanded, it shows the additional view and when its collapsed it should hide that view.
I need to do something like this :
.
Is it a UITableView? Or how should I do this? Any idea is welcome.
Code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.section == 0) {
if (indexPath.row == 0) return cell1;
} else if (indexPath.section == 1) {
if (indexPath.row == 0) return cell2;
} else if (indexPath.section == 2) {
if (indexPath.row == 0) return cell3;
}
}
Most likely its a UITableView. May be its not (it can be a UIScrollView with views added like sections in a table view).
But if you want to create something like in the image, I'd suggest you to use UITableView with customized cells. Because implementing table view, in this case, is simpler as you have to just concern about the delegate and the dateSource of the table view, rather than worrying about aligning the views in order.
Use sectioned table view with the translucent, gray-bordered, black-background-view as the backgroundView of the cells. Add the labels and arrow as the subviews of cell. You can add arrow as the accessoryView but that would become vertically centered, but in the image the arrow is displayed slightly on top of the cell.
There should be only one cell in each section.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 1;
}
There can be any number of sections (3 here).
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 3; // Can be any number
}
Yes, that's most likely a styled table view. See this guide or this nice tutorial.
why you worry about this one? Its simple man.... its nothing ,if you have hands over UITableView. Yeah, You must know about :
1: Set background image on view,exact as table size.
2: Set table view onto them and make background transparent.
3: Make customize table cell and add to table' row.
Thats it.....enjoy this work..its a creativity.
And you can do it guy....
I cannot tell exactly what is used from the picture, however I suggest using the UITableView especially if you have variable data coming from a structured object.
Some tutorials which I found very useful are the following:
Creating customized UITableViewCell from XIB
http://www.bdunagan.com/2009/06/28/custom-uitableviewcell-from-a-xib-in-interface-builder/
UIViewTable anti-patterns - A very good MVC pattern to build UIViewTable
http://www.slideshare.net/nullobject/uitableviewcontroller-antipatterns
And of course Apple's docs:
http:/developer.apple.com/library/ios/#DOCUMENTATION/UserExperience/Conceptual/TableView_iPhone/TableViewCells/TableViewCells.html
One important fact to remember is that you should always reuse cached table cells through the datasource method tableView:didSelectRowAtIndexPath:
Note: Since you want lots of transparencies there might be some performance issue especially on older devices.
Hope this helps and goodluck with your project.
There is not need to its scrollview or tableview... both are perform same..
Just change the Background Color of Tableview as clear color.....
check this code...
put this line to viewDidLoad :
[tableView setBackgroundColor:[UIColor clearColor]];
and
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
..... // Your label buttons etc........
......
......
.....
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell setClipsToBounds:YES];
[[cell layer] setBorderColor:[[UIColor blackColor] CGColor]];
[[cell layer] setCornerRadius:10];
}
You can do this using tableView in
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
//here place return your array contents
}
We can accomplish the similar as shown in image above by Table View and scroll view both.If you don't want to use table view then you can take a scroll view or a simple view and can add several buttons along with the image in background with different frames.It means button background will have the same image.then you can use different labels to show all the texts in different labels according to the requirement.
OR
you can use table view.For this you need to return number of sections 3(in this image) in the delegate method - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView.and then everything as the default tableview style.And then change the cell style to detailed.
yes this is a tableView with custom UITableViewCell.you can do that by creating a empty xib file and then add a UITableViewCell and do your customizing ...then in cellForRowAtIndexPath method use:
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:edentifier];
if (cell == nil) {
cell = [[[NSBundle mainBundle]loadNibNamed:#"yourCellName" owner:self options:nil]objectAtIndex:0];
this is from my application.
Yes, it is a groupedtableview with clearcolor as backgroundcolor. Cell background color also needs to be changed to clearcolor.
I suggest using div or list, don't use table, its very hard to control if the contents are too long.
