需要删除 .m 文件的引用，然后再次添加它们 iOS

Question

我在 Xcode 项目中的多个位置更改了我的 .h 文件的 prefix header 名称，然后将标题改回原来的。看来我弄乱了我的来源或其他东西。当尝试从 UIButton 控制单击拖动到我的 .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

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

我认为我需要删除引用然后将它们添加回来，但我该怎么做呢？

按照这个：-

To Delete reference:_
1. Right click on your .h or .m file. 
2. Click on "Delete". A pop up will open.
3. Click on "Remove reference". Your file reference has been deleted.

To add it again:-
1. Right click on your project. 
2. Click on "Add files to 'YourProjectName'". 
3. A pop up will open. Select you file & Click Add.
Note:- Make sure "Copy items into destination group's folder(if needed)" is unchecked.
