在尝试使用jQuery1.11和本机javascript向元素添加选项时，我收到了以下崩溃报告。有什么想法吗？有人知道这次坠机事件吗

iPad、iOS 8.1

值得注意的是，我在iOS 8.1和8.2上遇到了同样的问题，但似乎在8.3中得到了纠正。在为选择菜单呈现UITableView时，iOS在尝试ContentOffsetForScrollingToRowatineXPath方法时出现问题。也许苹果在调用contentOffsetForScrollingToRowAtIndexPath之前更改了控件实例化的点或调用方法以确保数据源中存在数据。只是我对修复的猜测，但这个问题肯定是方法调用。
