【问题描述】:
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,它运行良好。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

就像一个问题:打开 Xcode 4.4.1 并检查 UITouch.h 头文件。你看到那里声明的这些变量了吗?它们没有在 iOS 6.1 头文件中声明,所以我认为它们不再可用(如果它们在 iOS 5.x 的 UITouch.h 文件中,那么这证实了我的理论,但我无权访问它们)。这个框架在 2 年前就被废弃了,所以我不知道你为什么要尝试使用它。此类还严重依赖于实现细节,如果正在积极维护这很好,否则只是破坏的秘诀。
