我正在尝试创建从 tableview 中删除行的功能，这就是我做到的.错误来自

I'm trying to create the capability of deleting rows from a tableview and this is how I did it. The error is coming from the

非常感谢任何帮助.谢谢！

Any help would be very much appreciated. Thank you!

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


    if (editingStyle == UITableViewCellEditingStyleDelete) {

        [self.homeworkArray removeObjectAtIndex:indexPath.row];

        [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath] withRowAnimation:UITableViewRowAnimationFade];
    }

    [self.tableView reloadData];

}

推荐答案

arrayWithObjects: 方法需要一个 nil 来终止列表，所以你需要说 -

the arrayWithObjects: method requires a nil to terminate the list, so you need to say -

[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath,nil] withRowAnimation:UITableViewRowAnimationFade];
}

或者更简单，使用 arrayWithObject:

[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}

或者如@rmaddy 指出的那样，使用数组字面量语法 -

Or as @rmaddy points out, use array literal syntax -

[self.tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}

此外，您不需要 reloadData 调用 - deleteRowsAtIndexPaths 将负责更新表视图中的相关行.

Also, you don't need the reloadData call - deleteRowsAtIndexPaths will take care of updating the relevant rows in the table view.
