我使用自定义AlertView MZFromSheetController，但它给了我以下异常
*** Assertion failure in -[MZFormSheetController presentAnimated:completionHandler:], /Users/dt4it/Documents/SucessQuotes11/SucessQuotes/MZFormSheetController.m:418
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Attempting to begin a form sheet transition from to while a transition is already in progress. Wait for didPresentCompletionHandler/didDismissCompletionHandler to know the current transition has completed'
有谁能告诉我如何解决这个问题？
答案 0 :(得分：1)
确保您没有多次调用表示方法，我只是遇到了这个问题，发现代码被调用了4次。将其降低到1（应该是这样）修复了断言失败异常。
