在 Three20 框架的帮助下，我有一个示例项目。在 xcode 4.4.1 上运行时，它工作正常。在同一个项目中，在 Xcode 4.5.2 和 Xcode 4.6.2 上运行时，我遇到了错误。

some of the errors are :

/three20/src/Three20UI/Sources/UIViewAdditions.m
/three20/src/Three20UI/Sources/UIViewAdditions.m:109:5: Unknown type name '_tapCount'; did you mean 'ItemCount'?

If you are running an up-to-date version, you probably have DEBUG_TOUCH defined. Undefine it and the errors should disappear.
