The application crashes at replaceobjectatindex . The clickedbuttonpath.row returns nil value . Need help .

- (void)textFieldDidEndEditing:(UITextField *)textField 
{ 
if (textField.text.length>0)
 { 
UITableViewCell *clickedCell = (UITableViewCell *)[[textField superview] superview];
 NSIndexPath *clickedButtonPath = [addSizesTableView_ indexPathForCell:clickedCell]; 
if (textField.tag==6) 
{ 
[textDic setObject:textField.text forKey:clickedButtonPath]; 
[orderArr replaceObjectAtIndex:clickedButtonPath.row withObject:textField.text];

This is the crash log which am getting .

[[textField superview] superview] returns nil, incase of iOS 8, whereas in iOS 7 it returns some value. As suggested in below link, don't rely on view hierarchy.

You can check this link Getting UITableViewCell from its superview iOS 7 issue

You can try below like structure

CGPoint subviewPosition = [textField convertPoint:CGPointZero toView:self.tableView];
NSIndexPath* clickedButtonPath = [addSizesTableView_ indexPathForRowAtPoint:subviewPosition];

  • Thanks Vinoth . I tried your code but the problem is that the application is crashing at [orderArr replaceObjectAtIndex:clickedButtonPath.row withObject:textField.text]; – Nikilicious Feb 03 '15 at 11:57
  • Can you keep a breakpoint or NSLog and see clickedCell is getting a non nil value in iOS 8.? Because if clickedCell is nil, then clickedButtonPath will be nil, then clickedButtonPath.row will be nil. – Vinoth Kumar Feb 03 '15 at 12:02
  • UITableViewCell *clickedCell = (UITableViewCell *)[[textField superview] superview]; – Vinoth Kumar Feb 03 '15 at 12:09
  • clickedCell is not giving a nil value . – Nikilicious Feb 03 '15 at 12:24
