UITableViewCell indexPath crash in iOS7

Question

I\'ve a UITableViewCell in a UITableViewController. In my cell there is a button that when you click takes you to another view with a

Answer 1

In iOS7 UITableViewWrapperView is the superview of UITableViewCell, which means another superview for you:

iOS7:

UITableView *tableView = (UITableView *)cell.superview.superview;

iOS6"

UITableView *tableView = (UITableView *)cell.superview;

Another change you can find it here:

seems your code: UITableView table = (UITableView)[[[sender superview] superview] superview]; returns a UITableViewCell not a UITableView.

Try the below:

UITableView *table = (UITableView*)[[[[[sender superview] superview] superview] superview] superview];

I had similar problem where I had to find the textFileds value from TableView

if ([Util isiOSVerGreaterThen7]) { // iOS 7
            UIView *contentView = (UIView *)[textField superview];
            UITableViewCell *cell = (UITableViewCell *)[contentView superview];
            UITableView *tableView = (UITableView *)cell.superview.superview;
            NSIndexPath *indexPath = [tableView indexPathForCell:cell];

            NSInteger sectionOfTheCell = [indexPath section];
            NSInteger rowOfTheCell = [indexPath row];
        }
        else { // iOS 6
            UITableViewCell *cell = (UITableViewCell *)[textField superview];
            UITableView *table = (UITableView *)[cell superview];
            NSIndexPath *pathOfTheCell = [table indexPathForCell:cell];
            NSInteger sectionOfTheCell = [pathOfTheCell section];
            NSInteger rowOfTheCell = [pathOfTheCell row];
        }

And Util is

+ (BOOL)isiOSVerGreaterThen7 {
    if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
        return NO;
    } else {
        return YES;
    }
}

This is the best way I think:

CGPoint subviewPosition = [sender convertPoint:CGPointZero toView:self.myTable];

NSIndexPath* indexPath = [self.myTable indexPathForRowAtPoint:subviewPosition];

You can simply get the index path here. Be it iOS7 or iOS6, it will return the correct index path

Answer 4

Apple change the UITableViewCell hierarchy in iOS 7

Using iOS 6.1 SDK

<UITableViewCell>
   | <UITableViewCellContentView>
   |    | <UILabel>

Using iOS 7 SDK

<UITableViewCell>
   | <UITableViewCellScrollView>
   |    | <UITableViewCellContentView>
   |    |    | <UILabel>

So if you want to get indexpath at button index then use following code Using iOS 6 or later SDK

UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview];
    NSIndexPath *clickedButtonPath = [book_table indexPathForCell:clickedCell];
    NSLog(@"index=%@",clickedButtonPath);

Using iOS 7 or 7+ SDK

UITableViewCell *clickedCell = (UITableViewCell *)[[[sender superview] superview]superview];
    NSIndexPath *clickedButtonPath = [book_table indexPathForCell:clickedCell];
    NSLog(@"index=%ld",(long)clickedButtonPath.item);

Answer 5

This is better to use

NSIndexPath *indexPath = [self.callTable indexPathForCell:(UITableViewCell *)[[[sender superview] superview] superview]];
    NSLog(@"%d",indexPath.row);

Answer 6

It works for sure, but how super can we get?
