Xcode MyProjectName-Bridging-Header.h 不存在 [英] Xcode MyProjectName-Bridging-Header.h does not exist

问题描述

我想在我的 Objective-C 项目中开始使用 Swift.所以我添加了一个 swift 类:

I want to start using Swift in my Objective-C project. So i added a swift class:

import Foundation
@objc class System : NSObject {
    @objc func printSome() {
        println("Print line System");
    }
}

并将其导入到 .m 文件中:

And imported it into a .m file:

#import "MyProjectName-Swift.h"

在构建我的项目时，我收到以下错误:

When building my project i get the following error:

Bridging header 'PathToMyProject/MyProjectName-Bridging-Header.h' does not exist

注意:在Build Settings->Swift Compiler - Code Generation->Objective-C Briding Header"下设置为 MyProjectName-Bridging-Header.h

NOTE: Under "Build Settings->Swift Compiler - Code Generation->Objective-C Briding Header" is set to MyProjectName-Bridging-Header.h

我应该怎么做才能解决这个问题?

What should i do to solve this issue?

非常感谢任何帮助.

推荐答案

如果桥接文件是在与其他类相同的级别创建的，您可能需要添加相对路径，如这些图片所示.请注意，桥接文件是在与其他类相同的级别创建的:

If the bridging file is created at the same level as the other classes, you might need to add the relative path, as these pictures show. Note here that the bridging file is created at the same level as the other classes:

我在构建设置中正确输入了名称，

I have the name entered correctly in the Build Settings,

但是编译器没有找到该文件.

but the compiler doesn't find the file.

因此，如果我从项目的根目录添加相对路径(即添加./ProjectName/BridgerFileName.h)，

Therefore, if I add the relative path from the root of the project (that is, I add ./ProjectName/BridgerFileName.h),

现在它可以编译了，我可以在我的 Objective C 类中调用一个方法:

now it compiles and I can call a method in my Objective C class:
