IOS 7: The first relay my app works with has changed in the textbox
I have an editable tableview cell and when I go from the first textbox to the last textbox in the table it breaks. Code. Below is the code for the textbox delegate
-(void)textFieldDidBeginEditing:(UITextField *)sender
{
NSIndexPath *indexpath = [NSIndexPath indexPathForRow:sender.tag inSection:1];
EditableTextFieldCell *cell = (EditableTextFieldCell *)[self.documentdetailTable cellForRowAtIndexPath:indexpath];
self.actField = cell.textFieldOne;
if([self.actField canBecomeFirstResponder]){
[self.actField becomeFirstResponder];
}
}
-(BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
if (self.actField == textField) {
[self.actField resignFirstResponder];
}
return YES;
}
-(void)textFieldDidEndEditing:(UITextField*)sender
{
if (self.quantityValue !=nil)
{
[self.quantityArray replaceObjectAtIndex:[sender tag] withObject:sender.text];
[[self.documentItemsArray objectAtIndex:[sender tag]] setQUANTITY:[NSNumber numberWithDouble:[sender.text doubleValue]]];
[self.documentdetailTable reloadData];
}
}
- (BOOL)textFieldShouldClear:(UITextField *)textField {
self.quantityValue=@"";
return YES;
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
-(void)textFieldDidChange:(UITextField *)theTextField
{
NSLog( @"text changed: %@", theTextField.text);
self.quantityTextField = theTextField;
self.actField = theTextField;
}
//add the textfield listeners
[self.quantityTextField addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingDidBegin];
But it crashes and I get a message like:
**EditableTextFieldCell _didChangeToFirstResponder:]: message sent to deallocated instance 0xc3c6bf0**

Maybe this answer is somewhat silly, but the correct answer. I checked for tableview cellforrowatindexpath and added id
static NSString *EditableTextFieldCellIdentifier = @"EditableCell";
// using custom cells to show textfield and multiple columns
EditableTextFieldCell *cellText = [tableView dequeueReusableCellWithIdentifier:EditableTextFieldCellIdentifier];
And that fixed my problem as well as the crash.

We had the same problem, and precisely because we used the "old code" to create / delete the UITableViewCells class ...
We needed to add these lines to ViewDidLoad
[self.myTableView registerClass:[ExpenseListCell class] forCellReuseIdentifier:@"ExpenseListCell"];
[self.myTableView registerNib:[UINib nibWithNibName:@"ExpenseListCell" bundle:nil] forCellReuseIdentifier:@"ExpenseListCell"];
and then "clear" the cellForRowAtIndexPath function to just use the dequeue function:
ExpenseListCell *cell = (ExpenseListCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
I suspect that since they included storyboards, the dequeueReusableCellWithIdentifier controls the creation of the cells, so you no longer need these lines, which we still use after the dequeue:
if(cell == nil)
{
cell = [[[NSBundle mainBundle] loadNibNamed:@"ExpenseListCell" owner:cell options:nil] objectAtIndex:0];
}
NOTA: We do not use storyboards
By changing this, we have resolved the issue on iOS7.

There was the same problem. I fixed it by putting the id in the table cell file nib file. then calling dequeue on cellForRowAtIndexPath:
static NSString *fsCellIdentifier = @"configurationCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:fsCellIdentifier];
