didBeginContact在xcode 6之後沒有被調用

Question

我一直有xcode的問題。例如，NSLog不打印，case語句不工作等等。我在xcode 6出來之前就創建了這個項目，並且認爲如果我將它切換到在xcode 6中創建的新文件，這些東西將會被修復。到目前爲止，他們已經修復。但是，更多的問題發生了。其中一個主要原因是didBeginContact方法現在沒有被調用。我已經盡力解決它。我更改了類別掩碼，它們的值，collisionBitMask，contactBitMask，放入了不同的基礎，但沒有任何工作。它在xcode 6出來之前生成的文件中工作，但不在xcode 6中。

應該在玩家和對手之間檢測到聯繫，但它不再工作。 我把斷點放在didBeginContact方法上，並且在玩家和對手之間有聯繫時它應該調用的方法，但程序沒有退出。

在此先感謝！

固定！ 這是因爲聯繫人委託在initWithSize，這是不是因爲某種原因被稱爲...
