单击按钮时应用程序会终止进程

Question

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。但是我不断收到同样的错误，我不明白出了什么问题。我对 xcode 很陌生，并且我在互联网上搜索过帮助。我将发布可能需要的所有信息，并希望能够使其正常工作。

Answer 1

看到这个错误消息了吗？

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 未在其中列出。

您需要编写一个 -pushBetter 方法并将其连接到 UIButton。

Answer 2

看起来您以某种方式向您的视图控制器发送了一个pushBetter方法调用，但它显然没有准备好（根据您的代码和错误）：

-[HBFSViewController pushBetter]: unrecognized selector sent to instance 0x693ccb0' 

您可以全局搜索“pushBetter”并查看它在您的位置吗项目？？
