MZFormSheetController斷言失敗

Question

我使用自定義AlertView MZFromSheetController，但它給了我下面的異常

*** 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' 

誰能告訴我怎麼解決這個問題？

Answer 1

確保您沒有多次調用演示文稿方法，只是遇到了這個問題，並發現代碼被調用了4次。將其降低到1（應該是這樣），修復了斷言失敗異常。
