我正在开发一个应用程序。我准备了一个带有四个答案框的问题，每个答案框都有一个带有 UILable 的视图，并启用了 UIView 和 UILable 的用户交互，并使用相同的方法为不同的点击手势对象准备了点击手势，当我点击任何按钮第一次响应并在控制台中打印以下内容需要一些时间。请为此问题提供一些帮助。

请检查这个答案： 这个 gdb 输出是什么意思？

总结：这个错误只是来自模拟器的系统框架的控制台噪音，你应该忽略它，它不会影响你。

从您的错误来看，编译器似乎无法找到您添加到项目中的框架。检查您是否正确添加了所需的框架。

更新

经过一番搜索后，我遇到了几个有类似问题的问题，这似乎是 iOS SDK 5 Simulator 的一个已确认错误，这意味着如果你在设备上运行就可以了。只需尝试在 iOS 5.1 以外的模拟器上运行它，您可能不会遇到此问题。我建议您像在 Xcode 4.5 中一样升级您的 X 代码，这个问题就解决了。
