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

问题描述

我想在Objective-C项目中开始使用Swift。所以我添加了一个快速的类：

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.m文件：

#importMyProjectName-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

我该怎么做才能解决这个问题？

What should i do to solve this issue?

任何非常感谢帮助。

推荐答案

如果桥接文件创建的级别与其他类相同，则可能需要添加相对路径，如这些图片所示。请注意，桥接文件创建的级别与其他类相同：

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Build Settings中正确输入了名称，

I have the name entered correctly in the Build Settings,

但编译器找不到该文件。

but the compiler doesn't find the file.

因此，如果我从项目的根添加相对路径（也就是说，我添加 ./ ProjectName / BridgerFileName.h ），

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

现在它编译，我可以调用一个方法我的目标C类：

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