UITextViews not cleared when selected in a UITableView - ios

I'm implementing a UITableView with text-views as the content view of my cells.
The data that the user enters is saved in a settings dictionary when the user hits the return key:
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
if (textField == _textFieldOne){
[settingsDictionary setObject: _textFieldOne.text forKey:#"EntryOneText"];
[settingsDictionary stringValueForKey:#"textFieldOneValue"];
[self postNotificationSettingsUpdate:settingsDictionary];
didTestPostNotificationSettings = YES;
}
These saved values should be displayed in the text-field when the user returns back to the screen, which I've done using the code below:
//Set the value in the text fields from the settings dictionary
NSString *textFieldOneText = [self.settingsDictionary stringValueForKey:#"RedZoneCarsPerManHrMin"];
_textFieldOne.text = textFieldOneValue;
So far, everything seems to work as expected: text input is saved, and shown in the text-field when the user returns to screen. However, if the row of the TableView that holds the text-field is select (not the text-field itself), the text-field displays the behavior shown below:
It appears as if the text-field is showing both the newly inputted entry, as well as the entry that was last saved.
EDIT I'ved added more of my cellForRowAtIndexPath method below:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForSubscribedRedZoneAlertRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"RedZoneAlertCell";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
}
cell.backgroundColor = [UIColor colorWithRed:0.922 green:0.937 blue:0.949 alpha:1];
UISwitch *cellSwitch = nil;
NSNumber *position = enabledRedZoneAlertRows[indexPath.row];
switch (position.integerValue) {
case CarPerManHourRow: {
cell.textLabel.text = NSLocalizedString(#"Label", #"Label Row");
cellSwitch = [[UISwitch alloc] init];
cellSwitch.on = [[NSUserDefaults standardUserDefaults] boolForKey:SwitchKey];
cellSwitch.tag = SwitchTag;
[cellSwitch addTarget:self action:#selector(switchChanged:) forControlEvents:UIControlEventValueChanged];
cell.accessoryView = cellSwitch;
if ([[self.settingsDictionary valueForKey:#"RedZoneCarsPerManHrOnOff"]isEqual: #"1"]){
[cellSwitch setOn:YES];
}
break;
}
case TextFieldRow: {
static NSString *CellIdentifier = #"ConfigCell";
cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
[cell.contentView addSubview:_textFieldOne];
[cell.contentView addSubview:_textFieldTwo];
[cell.contentView addSubview:_spacingLabel];
}
cell.backgroundColor = [UIColor colorWithRed:0.922 green:0.937 blue:0.949 alpha:1];
_textFieldOne = [[UITextField alloc]initWithFrame:CGRectMake(25, 0, 50, 30)];
_textFieldTwo = [[UITextField alloc]initWithFrame:CGRectMake(100, 0, 50, 30)];
_textFieldOne.delegate = self;
_textFieldTwo.delegate = self;
_textFieldOne.placeholder = #"Auto";
_textFieldTwo.placeholder = #"Auto";
[_textFieldOne setTextAlignment:NSTextAlignmentCenter];
[_textFieldTwo setTextAlignment:NSTextAlignmentCenter];
//Set the value in the text fields from the settings dictionary
NSString *textFieldOneText = [self.settingsDictionary stringValueForKey:#"RedZoneCarsPerManHrMin"];
NSString *textFieldTwoText = [self.settingsDictionary stringValueForKey:#"RedZoneCarsPerManHrMax"];
NSString *carsPerManHrMax = [self.settingsDictionary stringValueForKey:#"RedZoneCarsPerManHrMax"];
NSString *carsPerManHrMax = [self.settingsDictionary stringValueForKey:#"RedZoneCarsPerManHrMax"];
_textFieldOne.text = textFieldOneValue;

[_textFieldTwo setKeyboardType:UIKeyboardTypeNumbersAndPunctuation];
_textFieldOne.returnKeyType = UIReturnKeyNext;
_textFieldTwo.returnKeyType = UIReturnKeyDone;
_spacingLabel = [[UILabel alloc] initWithFrame:CGRectMake(70, 0, 35, 30)];
_spacingLabel.text = #"–";
_spacingLabel.textColor = [UIColor colorWithRed:0.658 green:0.658 blue:0.658 alpha:1];
[_spacingLabel setTextAlignment:NSTextAlignmentCenter];
_spacingLabel.backgroundColor = [UIColor clearColor];
//[cell.contentView addSubview:_textFieldOne];

//[cell.contentView addSubview:_spacingLabel];
break;
}
return cell;

How do I modify my code so that this behavior does not occur?

Check your cellForRowAtIndexPath, as cells are reused, you are probably not loading the cell property.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
/*
* This is an important bit, it asks the table view if it has any available cells
* already created which it is not using (if they are offscreen), so that it can
* reuse them (saving the time of alloc/init/load from xib a new cell ).
* The identifier is there to differentiate between different types of cells
* (you can display different types of cells in the same table view)
*/
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"MyIdentifier"];
/*
* If the cell is nil it means no cell was available for reuse and that we should
* create a new one.
*/
UILabel *label;
if (cell == nil) {
/*
* Actually create a new cell (with an identifier so that it can be dequeued).
*/
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"MyIdentifier"] autorelease];
label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 30)];
cell.tag = 1;
[cell.contentView addSubview:label];
} else {
label = (UILabel *)[cell.contentView viewWithTag:1];
}
/*
* Now that we have a cell we can configure it to display the data corresponding to
* this row/section
*/
label.text = #"whatever";
}
EDIT: When your cell exits and it's reused, you are adding a view ([cell.contentView addSubview:_textFieldOne]) each time the cell is reused.

Ok, it is as I suspected. Every time the cell is taken out out the reuse queue, you create a new instance of textfield and add it to the content view. So basically the content view is piling up with new textfields.
What you should do is
1) to have a custom cell and make the cell the sole class responsible for its internals
2) expose only a configuration method to pass a raw text to cell
3) call that configuration method when thr cell is reused.
4) keep a reference to the textfield inside the custom cell to be able to update the text value any time incl. when it is recycled in cellforrowatindexpath

Issue assigning action to UIButton in TableView Cell creation

I am populating a TableView dynamically with data called from a server. I have 2 main files, one for the new cell and one for handling the population of the cells within the TableView Now when I assign [cell.button addTarget:self action:#selector(addFriend:) forControlEvents:UIControlEventTouchUpInside]; to my button within the cellForRowAtIndexPath and I put an output to log the action of the clicking of the button, nothing happens.
Here is what I am doing:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

.......
/* Setup button action */
[cell.button addTarget:self action:#selector(addFriend:) forControlEvents:UIControlEventTouchUpInside];

Premise that you should provide more code to have a clear idea of what is happening,
this is not the best approach.
At least I hope you are adding the target just if the cell is nil and you are init that and not more and more time :)
But anyway, the correct approach in functionality and design, is to implement the button action in the cell subclass, and return back by a delegate the cell where the button touched was.
I explained the various approaches here, the last one is this.
Enjoy clean code and good design ;)

Tableview is not displaying any cells or rows content in new pushed viewController

I'm not sure what I'm missing but I'm trying to display a new viewController and passing some data to it, but the problem is when this new viewController gets pushed it doesn't display the cells or rows content like labels, textfields and so on..
This is how I'm pushing from one controller to another..
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
BillComparatorViewController *vc = [[BillComparatorViewController alloc] init];
vc.selectedInstitution = [self.myInstitution objectAtIndex:indexPath.row];
vc.managedObjectContext = self.managedObjectContext;
[self.view endEditing:YES];
[self.navigationController pushViewController:vc animated:YES];
}
Then in my new pushed view controller this is my cellForRowAtIndexPath function..
//UITableView Delegate + Datasource
- (UITableViewCell*) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

}
else if (i > kTableRowHeight)

}
if (isSearching)
{
cellLabel.text = [searchElements objectAtIndex:indexPath.row];
[cell.contentView addSubview:cellLabel];
}
}
return cell;
}
It's a bit long sorry but I think it was important to post it..
UPDATE
This is how the problem happens, when user select a row within the current viewcontroller didSelectRowAtIndexPath calls a new viewcontroller and pushes this controller but if the user does this while searching with the keyboard in the screen is when the problem happens that the new viewcontroller pushed doenst show any content in its tableview..
SOLVED
Within my cellForRowAtIndexPath
[cell setTranslatesAutoresizingMaskIntoConstraints:NO];
The issue is with Autolayout. I had the same problem with iOS 8 beta. (I know you're not using i OS 8 but still).
Try turning it off. Should sort the issue out.
i think the problem is initiating the object of BillComparatorViewController.
You do like this .You may get solution
BillComparatorViewController *vc = [[BillComparatorViewController alloc] initWithNibName:"BillComparatorViewController" Bundle:nil];

ios - adding text fields to uitableviewcell programmatically not working

Rookie ios question. I am trying to create a sign up form using a table view controller. I am trying add textfields to each cell programmatically in the cellForRowAtIndexPath method but all my text fields seem to getting created on the first cell - one overlapping the other. Here is my code.
Here is how my cells are rendering. I think I am doing something goofy with the part that is reusing the cells. I did check some some other similar threads on stackoverflow but none of them helped. Could you please tell me what i am missing or is this even the way this is supposed to be done. Your inputs are really appreciated.
Thanks,
Mike

no need to add again text view in table view, this is wrong. Try this, this will work for you but better you should create a custom Cell and use. That is the best way to do it, because you can use whatever you want with Cell.
Don't add them as subviews, set them as the cell's accessory view.

The idea is that the cell is re-drawn each time it appears on screen, coming from off the screen and if you add the text field with addSubview:, it will add it each time as well. You COULD do it, but then you have to clear the cell's contentView of subviews, but that requires extra work, cpu and memory use, and not to say it's the least elegant solution.
Looks like you have just four cells you want to display. This is a static case, the cells don't change, you should create this tableView and its cells statically in the xib/storyboard. That is the preferred way here.
If you really want to do it programmatically, create four UITableViewCells with the behavior you want before hand. Keep them in an array. Inside cellForRowAtIndex path return cellArray[indexPath.row];
Note this is the best approach only because you have just four tableViewCells.
ReuseIdentifiers come in handy only if you have more cells than can be accommodated on the screen at once. So in your case, you never actually reuse the cells.
keep this one and try it,
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *MyIdentifier = [NSString stringWithFormat:#"%d%d",indexPath.row,indexPath.section];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
//your stuff.
}
}
Try to use this one ...And there is no need to add these textfield to tableview. So please remove some code..
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"signUpFields" forIndexPath:indexPath];
// Configure the cell...
if (indexPath.row == 0){
//self.firstName = [[UITextField alloc] initWithFrame:CGRectMake(5, 0, 280, 21)];
self.firstName = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
self.firstName.placeholder = #"First Name";
self.firstName.autocorrectionType = UITextAutocorrectionTypeNo;
[self.firstName setClearButtonMode:UITextFieldViewModeWhileEditing];
//cell.accessoryView = self.firstName;
[cell addSubview:self.firstName];
}
if (indexPath.row == 1){
self.lastName = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
self.lastName.placeholder = #"Last Name";
self.lastName.autocorrectionType = UITextAutocorrectionTypeNo;
[self.lastName setClearButtonMode:UITextFieldViewModeWhileEditing];
//cell.accessoryView = self.lastName;
[cell addSubview:self.lastName];
}
if (indexPath.row == 2){
self.emailId = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
self.emailId.placeholder = #"Email Id";
self.emailId.autocorrectionType = UITextAutocorrectionTypeNo;
[self.emailId setClearButtonMode:UITextFieldViewModeWhileEditing];
//cell.accessoryView = self.emailId;
[cell addSubview:self.emailId];
}
if (indexPath.row == 3){
self.password = [[UITextField alloc] initWithFrame:CGRectMake(120, 13, 375, 30)];
self.password.placeholder = #"Password";
self.password.secureTextEntry = YES;
self.password.autocorrectionType = UITextAutocorrectionTypeNo;
[self.password setClearButtonMode:UITextFieldViewModeWhileEditing];
//cell.accessoryView = self.password;
[cell addSubview:self.password];
}
self.firstName.delegate = self;
self.lastName.delegate = self;
self.emailId.delegate = self;
self.password.delegate = self;

return cell;
}
Instead of writing more cells just create one custom cell with textfield.Give the tag for each textfield and also set the count of rows in numberOfRowsIntheSections then it will display the cells how much you need. I think it will helps you.
Before You follow my Answer i wnat to tell you that following code is bad for memory management because it will create new cell for each rows of UITableView, so be careful for it.
But it is better to use, When UITableView Have Limited rows (about 50-100 may be ) then following code is helpful in your case, use it, If it is suitable for you.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = [NSString stringWithFormat:#"S%1dR%1d",indexPath.section,indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
/// Put/Create your UITextField or any Controls here
}
return cell;
}
#Mike : First of all I will suggest you to go with StoryBoard or Nib files.
If you use this, then you can use following code
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
UITextField *txtField = (UITextField *)[cell viewWithTag:1];
txtField.text = #"Latest";
return cell;
}
Based on row number you can set text.
If you want to add the UITextField at run time. then you can use following code.
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
UITextField *txtField = [[UITextField alloc] initWithFrame:CGRectMake(165.0, 7.0, 150.0, 30.0)];
txtField.text = #"Latest";
[cell.contentView addSubview:txtField];
return cell;
}
You can assign different tag and based on tags you can store those values.

UITableView dequeue not working as expected

As I scroll down the list, all the rows are there, but they keep adding more subviews the more they appear on the visible frame
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *reuse = #"RuleCell";
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:reuse];
if (cell == nil){
cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:reuse];
}
NSUInteger row = indexPath.row;
[self createCell: cell onRow: row];
return cell;
}
- (void) createCell: (UITableViewCell*)cell onRow: (NSUInteger)row
{
UIImageView* bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"cell_background_spade_active.png"]];
cell.backgroundView = bgImage;
cell.textLabel.hidden = YES;
UILabel* titleLabel = [[UILabel alloc] initWithFrame: CGRectMake(100, CGRectGetHeight(cell.frame) / 2, 200, 50)];
titleLabel.text = [[self.ruleList objectAtIndex: row] objectForKey: TitleKey];
titleLabel.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview: titleLabel];
}
I think you need to execute almost all of the logic that's in createCell: only within the if (cell == nil){ segment of your code. The part that should execute where you're currently calling createCell: is just getting a reference to the titleLabel and setting its text value.
To clarify, here's the kind of modification I'm suggesting (not tested, but should give the right idea):
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *reuse = #"RuleCell";
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:reuse];
if (cell == nil){
cell = [[UITableViewCell alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:reuse];
[self setUpCell: cell];
}
NSUInteger row = indexPath.row;
UILabel *titleLabel = (UILabel *)[cell.contentView viewWithTag:42];
titleLabel.text = [[self.ruleList objectAtIndex: row] objectForKey: TitleKey];
return cell;
}
- (void) setUpCell: (UITableViewCell*)cell
{
UIImageView* bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"cell_background_spade_active.png"]];
cell.backgroundView = bgImage;
cell.textLabel.hidden = YES;
UILabel* titleLabel = [[UILabel alloc] initWithFrame: CGRectMake(100, CGRectGetHeight(cell.frame) / 2, 200, 50)];
titleLabel.tag = 42;
titleLabel.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview: titleLabel];
}

UItableView multiplle data printed

I am creating grouped table in my application.
It works fine. But when I scroll the table upward and backward reprinted text on previous cell. It look like horrible.
This is my Code

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}

Update
My original answer was not the correct way to reuse UITableViewCell's. You should never use "CellID%d%d"(indexPath.row & indexPath.column) as cell identifier, that defeats the very purpose of cell reuse. It will create separate UITableViewCell for every row in the table, and every one of those cells stays in memory. Imagine what will happen if you have a tableView with around 1000 rows.
The real answer to OP's question is - make sure to reset a UITableViewCell returned by dequeueReusableCellWithIdentifier because it might return a cell that is already used and its UI populated. For example, if you didn't reset the texts in UILabel, it might contain strings that should have been shown in a different row of your tableView.
My original Answer (Don't use this)
Hiren, just try,
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[NSString stringWithFormat:#"CellID%d%d",indexPath.section,indexPath.row]];
if (!cell){
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:[NSString stringWithFormat:#"CellID%d%d",indexPath.section,indexPath.row]] autorelease];
}
instead of
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cellID"];
if (!cell)
{
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:#"cellID"] autorelease];
}
Please read this..you will understand how to give cell identifiers..
When you create the UITableView object, Set the rowHeight for each cell.
myTableView.rowHeight = 50; //Depend on your requirement,
Let me know if you still struggle to get the desire result.
If your cell's height is not constant then implement heightForRowAtIndexPath method,
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
And return different-2 height for each cell.
try adding any color because clearcolor is making label transparent.
