When textFieldDidEndEditing gets called, the app freezes - ios

Question

I have a custom UITableView with UITextFields inside. In cellForRow... I made the textFields delegate to self. (In my main VC class.) The way I get the text from the textField is at textFieldDidEndEditing, and I add it to a mutableArray.
I then have different cell ids that get added when a button gets selected:
- (IBAction)addRow:(id)sender
{
NSInteger row = [self.rowArray cound];
[self.rowArray insertObject:#"anotherCell" atIndex:row];
NSIndexPath *indexPath = [NSindexPath indexPathForRow:row inSection:0];
[self.myTableView insertRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}
(There is a textField in that cellID and I set the delegate to self.)
In textFieldDidEndEditing, I made an NSLog of textField.text, and when that method gets called from a textField that was there initially, it works as expected.
But when textFieldDidEndEditing gets called from the textField that's in the cell of anotherCell (the added cell), then the whole simulator freezes.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cellID = [self.rowArray objectAtIndex:[indexPath row]];
customCell *cell = [tableView dequeuereusablecellwithidentifier:cellID forIndexPath:indexPath];
cell.name.delegate = self; // From cell that is initially there
cell.phoneNumber.delegate = self; // From the added cell
return cell;
}
(If this is confusing, or if you need more code, just let me know in the comments. Thanks)
Edit
- (void)textFieldDidEndEditing:(UITextField *)textField
{
if (textField.tag <= 9)
{
NSLog(#"%#", textField.text); // This works
}
UIView *superview = textField.superview;
while (![superview isMemberOfClass:[UITableViewCell class]]) {
superview = superview.superview;
}
CustomCellClass *cell = (CustomCellClass *)superview;
NSIndexPath *indexPath = [self.myTableView indexPathForCell:cell];
if (textField.tag >= 12)
{
if ([self.inputArray count] > indexPath.row) // So I won't get the error message of [__NSArrayM objectAtIndex:]: index 1 beyond bounds for empty array'
{
for (NSUInteger i = [self.inputArray count]; i < indexPath.row; i++) {
[self.inputArray insertObject:#"" atIndex:i];
NSLog(#"%lu", (unsigned long)i);
}
}
NSLog(#"%#", self.inputArray);
}
}

Your code is stuck in an infinite loop here:
while (![superview isMemberOfClass:[UITableViewCell class]]) {
superview = superview.superview;
}
because isMemberOfClass will return true only if the superview class is UITableViewCell, but NOT if it is a subclass of UITableViewCell. If you change isMemberOfClass to isKindOfClass, it should work. Check the Apple docs here.
