Textfield in tableview cell crashes on iOS7

My code is working fine on iOS6 but crashing in iOS7.

I comparing the text field with table view cell text-field.

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{

    DLog(@"-> %@", textField.text);

    PhotoViewCustomCell *cell = (PhotoViewCustomCell*)[[textField superview] superview];
    NSIndexPath *indexPath = [tblPhotoDetail indexPathForCell:cell];

    //PhotoViewCustomCell *cell = (PhotoViewCustomCell *)[tblPhotoDetail cellForRowAtIndexPath:indexPath];

    PhotoInformation *objPhotoInfo = [selectedPhotos objectAtIndex:indexPath.row];

    if ([textField isEqual:cell.mytextfield]) 
    { =========>crashing in this line

       do something
    }
    else 
    {
      do something
    }
}

Error:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITableViewCellScrollView mytextfield]: unrecognized selector sent to instance 0xdc119a0'

The code in Accepted Answer is not the safer one and also can't be used for iOS 6. I'd rather recommend you to use this code. :

UIView *view = [textField superview];
while (![view isKindOfClass:[PhotoViewCustomCell class]]) {
    view = [view superview];
}
PhotoViewCustomCell *cell = (PhotoViewCustomCell *)view;

Add additional superview call to get your cell. Looks like you are getting hidden UITableViewCellScrollView which goes in hierarchy immediately above contentView 

 PhotoViewCustomCell *cell = (PhotoViewCustomCell*)[[[textField superview] superview] superview];
