从同一应用程序的框架访问嵌入在iOS应用程序中的静态库

Question

Is it possible to access the symbols from a static library added to an iOS app from a framework added in the same app.

I am trying to build an ios framework which has dependeny on a thirdparty static library which the customer buys. So the customer adds the static library to the app.

But my framework needs to read the symbols from the static library added in the app.

Any pointers will be much appreciated.

Answer 1

You should link your framework against that static library to do that. Otherwise, you can't access that static libraries' symbols. Because they are embedded in your customer's application.

Answer 2

Using 'Cocoapods' as a dependency manager will get you where you want:

For example - a framework that uses the Alamofire networking framework:

1. Create your framework project
2. Use Cocoapods and add 'pod 'Alamofire', '~> 4.0'' to your podfile.
3. Build your framework and add it to the project that intends to use this framework.
4. In you app project also add 'pod 'Alamofire', '~> 4.0' to your podfile

That's it.

By the way - if your app project will not add the dependent framework to its podfile, you'll see a linker error upon building the app which will look something like that:

"dyld: Library not loaded: @rpath/Alamofire.framework/Alamofire Referenced from: /private/var/containers/Bundle/Application/8B381B5F-6B86-4CDD-8A49-E0CBF9C04786/test.app/Frameworks/MyFramework.framework/MyFramework Reason: image not found"

Hope this is helpful.
