如何在Swift项目中使用Objective-C CocoaPods [英] How to use Objective-C CocoaPods in a Swift Project

问题描述

有没有办法在我的Swift项目中使用swift使用用Objective-C编写的CocoaPod?

Is there a way I can use a CocoaPod written in Objective-C in my Swift project using swift?

我只是制作桥接头吗?如果是这样，我可以在Swift中访问CocoaPod中的库定义的对象，类和字段吗?

Do I just make a bridging header? And if so, can I access the objects, classes, and fields defined by the libraries in the CocoaPod in Swift?

推荐答案

问题的基本答案是，可以使用CocoaPods内置的Objective-C代码.

Basic answer to your question is Yes, you can use objective-c code built with CocoaPods.

更重要的问题是如何使用此类库?"
关于此问题的答案取决于您Podfile中的use_frameworks!标志:
假设您要使用名称为CoolObjectiveCLib的Objective-C吊舱.

More important question is "How to use such libs?"
Answer on this question depends on use_frameworks! flag in your Podfile:
Let's imagine that you want use Objective-C pod with name CoolObjectiveCLib.

如果您的Pod文件使用use_frameworks!标志:

If your pod file uses use_frameworks! flag:

// Podfile
use_frameworks!
pod 'CoolObjectiveCLib'

然后，您无需添加任何桥头文件.
您需要的一切都是Swift源文件中的导入框架:

Then you don't need add any bridge header files.
Everything that you need is import framework in Swift source file:

// MyClass.swift
import CoolObjectiveCLib

现在您可以使用lib中提供的所有类.

Now you can use all classes that are presented in lib.

如果您的Pod文件不使用use_frameworks!标志:

If your pod file doesn't use use_frameworks! flag:

// Podfile
pod 'CoolObjectiveCLib'

然后，您需要创建桥接头文件，并在其中导入所有必需的Objective-C头文件:

Then you need create bridging header file and import there all necessary Objective-C headers:

// MyApp-Bridging-Header
#import "CoolObjectiveCLib.h"

现在，您可以使用在导入的标头中定义的所有类.

Now you can use all classes that are defined in imported headers.
