Question

我一直遇到xcode问题。例如，NSLog没有打印，case语句不能正常工作等等。我在xcode 6出来之前创建了这个项目，并且认为如果我将它切换到xcode 6中的新文件，这些东西将被修复。到目前为止，它们已被修复。但是，发生了更多问题。一个主要的问题是现在没有调用didBeginContact方法。我已经尝试过一切来解决它。我更改了类别掩码，它们的值，collisionBitMask，contactBitMask，放入了不同的基础，但还没有任何工作。它适用于xcode 6发布之前的文件，但不适用于xcode 6。

应该在玩家和对手之间检测到接触，但它不再起作用。我把断点放在didBeginContact方法和它应该在玩家和对手之间有联系时调用的方法，但程序没有退出。

提前致谢！

固定！这是因为联系代表在initWithSize中，由于某种原因没有被调用...

在xcode 6之后没有调用didBeginContact
