我有一個自定義的轉換事件與視圖控制器a（VC_A）將出現在視圖控制器（VC_B）。介紹未註冊的UIViewController觸摸事件
現在在做轉型的時候，VC_A仍將存在，但VC_B不會接收任何觸摸事件。現在，如果我從VC_A中刪除視圖，VC_B將獲得觸摸事件。我不確定我的轉換中缺少什麼，它告訴應用程序將所有觸摸事件發送到VC_B而不是VC_A。我曾嘗試設置第一響應者，但那不起作用，如果有人能告訴我我缺少什麼，那將不勝感激。

您可以發佈您的自定義轉換一些代碼？我記得在我的轉換上下文（'UIViewControllerContextTransitioning'）中沒有調用'completeTransition（_ :)'的類似問題。 –
好吧我清理了一下這個班，發佈了它，希望它有幫助。 – Knight0fDragon
http://stackoverflow.com/questions/22300050/touches-not-recognized-after-custom-transition是一個類似的問題，但當然，答案不是我可以接受的答案，我寧願保持視圖加載爲了我所做的。 – Knight0fDragon
