基本上我已经从另一个应用程序创建了一个音板应用程序。但是我一直得到同样的错误，我无法理解什么是错的。我是xcode的新手，我在互联网上搜索了一些帮助。我会发布所有可能需要的信息，希望能让这个工作起作用。

答案 0 :(得分：3)
请参阅此错误消息？
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[HBFSViewController pushBetter]: unrecognized selector sent to instance 0x693ccb0
现在查看您列出的所有IBAction方法（-pushAbout等）。
您会注意到-pushBetter未列在其中。
您需要编写-pushBetter方法并将其连接到UIButton。
答案 1 :(得分：1)
看起来你以某种方式向你的视图控制器发送了一个pushBetter方法调用，它显然没有准备好（根据你的代码和错误）：
-[HBFSViewController pushBetter]: unrecognized selector sent to instance 0x693ccb0'
您可以全局搜索“pushBetter”并查看它在项目中的位置吗？
