表视图单元格删除动画不起作用

Question

-(void)tableView:(UITableView *)tableView 
       commitEditingStyle:(UITableViewCellEditingStyle)editingStyle 
       forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
        [self.myArray removeObjectAtIndex:indexPath.row];
        [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] 
                              withRowAnimation:UITableViewRowAnimationFade];
    }
}

将动画类型更改为任何其他选项并没有什么区别，我似乎每次都获得相同的动画。我已经读过这可能是由于iOS 7错误，但我的部署目标是iOS 8。有什么想法吗？

Answer 1

if (editingStyle == UITableViewCellEditingStyleDelete)
{
    if ([self.myArray count] >= 1) 
     {
         [self.tableView  beginUpdates];
         [self.tableView  deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
         [self.myArray removeObjectAtIndex:[indexPath row]];
         [self.tableView endUpdates];
      }
} 

试试这个

你可以这样做，

    NSMutableArray *indexPathsToDelete = [NSMutableArray new];

    for (Object *object in newObjects)
    {
       if (![currentObjects containsObject:object]) {
          int row = [newObjects indexOfObject:object];
          NSIndexPath *indexPath = [NSIndexPath indexPathForRow:row inSection:0];
          [indexPathsToDelete addObject:indexPath];
       }
    }

    [tableView beginUpdates];
    [tableView deleteRowsAtIndexPaths:indexPathsToDelete withRowAnimation:UITableViewRowAnimationAutomatic];
    [tableView endUpdates];
