        [self.reports removeObjectAtIndex:indexPath.row];
        [tbl reloadData];
            [tbl deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath]

After much more R&D then i build up new code and which is successfully Run

if (editingStyle == UITableViewCellEditingStyleDelete) {
    // Delete the row from the data source

    [[[self.reports objectAtIndex:indexPath.section] valueForKey:@"events"] removeObjectAtIndex:indexPath.row];
    [tbl deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section]] withRowAnimation:UITableViewRowAnimationLeft];

[NSTimer scheduledTimerWithTimeInterval: 0.1 target: self selector: @selector(tableReload) userInfo: nil repeats: NO]; 
}

}

-(void)tableReload{
    [tbl reloadData];  }

推荐答案

首先你不应该在从表中删除行之前重新加载表。其次，在你的情况下，你想在那个部分有多个部分和多行。那么，你的

Firstly you should not Reload table before deleting row from table. Secondly, in your case you have multiple sections and multiple rows in that section, I guess. So, your

[tbl deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath] 
                                  withRowAnimation:UITableViewRowAnimationFade];  

不起作用。

从数组中删除对象将起作用。您不必从表中删除行。只需重新加载表：

won't work.
Deleting object from array will work. You don't have to delete row from your table. Just reload table :

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

    if (editingStyle == UITableViewCellEditingStyleDelete) {
        // Delete the row from the data source
        [self.reports removeObjectAtIndex:indexPath.row];
        [tbl reloadData];
}  

但要注意你正在放置正确的indexNumber。

But do take care that you are putting the correct indexNumber.
