problems with animation when deleting the last row of a TableView in ios7

Question

I\'m having some issues when deleting the last row of my (only) section in my tableView. Any other row works fine, but if I delete the row at the bottom of my <

Answer 1

I had the same bug. I just changed the animation type on UITableViewRowAnimationMiddle, and it fixed it all.

Here is a solution I found to work well that builds upon jaydee3's answer:

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{ 
     if (editingStyle == UITableViewCellEditingStyleDelete) {
          // hide cell, because animations are broken on ios7
          double iosVersion = [[[UIDevice currentDevice] systemVersion] floatValue];

          if (iosVersion >= 7.0 && iosVersion <= 8.0) {
              // Animating the cell's alpha change gives it a smooth transition
              // Durations > .17 show the glitch on iPad, phone looks nice up to 0.3
              [UIView animateWithDuration:0.17 animations:^(void) {
                  [tableView cellForRowAtIndexPath:indexPath].alpha = 0.0;
              }];
          }
          NSArray *deleteIndexPaths = [[NSArray alloc] initWithObjects:indexPath, nil];

          // UITableViewRowAnimationFade looks nice with the animation imho
          [tableView deleteRowsAtIndexPaths:deleteIndexPaths withRowAnimation:UITableViewRowAnimationFade];
     }
}

My solution to this painful issue :)

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    [UIView animateWithDuration:0.25f
                     animations:^{

                         UIScrollView *internalScrollView = (UIScrollView*)cell.contentView.superview;
                         if([internalScrollView isKindOfClass:[UIScrollView class]]){

                             [internalScrollView setContentOffset:CGPointZero animated:YES];
                         }

                         cell.center = CGPointMake(cell.center.x - cell.bounds.size.width, cell.center.y);

                     } completion:^(BOOL finished) {

                         [self.rowModels removeObjectAtIndex:indexPath.row];

                         [tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationLeft];
                     }];
}

Its a bug of ios7.. the tablerow animations are broken! My fix was to fadeOut the cell right before the tableViewRowAnimation..

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    // hide cell, because animations are broken on ios7
    double iosVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
    if (iosVersion >= 7.0 && iosVersion <= 8.0) {
        [tableView cellForRowAtIndexPath:indexPath].alpha = 0.0;
    }

    [tableView deleteRowsAtIndexPaths:@[indexPath]
                     withRowAnimation:UITableViewRowAnimationMiddle];
}
