Iphone didSelectRowAtIndexPath:嵌套推送动画

我正在尝试从DidSelectRowatingIndexPath:UITableView的委托方法中的NeoOfficesRootViewController推送NeoOfficesDetailViewController。此UITableView已连接NSFECTHERROUTSCONTROLLER

在一般情况下，一切正常， 但是如果在NSFetcherResultsController的上下文正在更改（单个上下文，主线程上的所有更改）时，在表的行上点击多次，将多次调用didSelectRowAtIndexPath:方法，这将导致嵌套推送动画

我还提到了一件奇怪的事情：didSelectRowAtIndexPath:在所有上下文计算完成后多次被调用，看起来UITableView将我的点击保存在队列中，然后（当主线程空闲时）释放它们。 因此，如果我在计算期间在表视图的行上点击4次，那么在所有计算之后，将调用4次didSelectRowAtIndexPath:method。 以下是我的调试列表：
