需要删除.m文件的引用，然后再次添加它们iOS

Question

我在几个地方的Xcode项目中更改了我的.h文件的prefix header名称，然后将标题更改回原始名称。似乎我搞砸了我的消息来源。尝试从UIButton控制点击拖动到我的.h文件以创建 IBAction 时，

我收到以下错误：

Could not insert new action connection: Could not insert source code into document at 
URL file://localhost/Users/Myuser/file/filename/projectname/SGLoginHomeViewController.m 
because it does not contain a class interface for the class named SGLoginHomeViewController

我再一次尝试在类文件SGLoginHomeViewController.h中创建一个新的 IBAction

我相信我需要删除引用然后再添加它们，但是我该怎么做呢？
