长按出现UIMenuController

当我给cell添加长按出现UIMenuController时，出现报错，

*** Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<UICompatibilityInputViewController: **> should have parent view controller:<**: **> but requested parent is:<UIInputWindowController: **>'

后台看到这篇文章《cell长按出错》，才发现报错的原因，

Your view controller probably has a property named inputView that is merely a subview, not an inputView as UIResponder interface expects it to be.

Starting with iOS 8 they check that UIResponder's inputView has no parent.

我把代码中出现的“inputView”全部替换成别的字段就没再有报错。
