如何从Swift类访问Freestreamer Objective C类？

Question

I am totally new to iOS development, and I decided to start directly with the new Swift programming language. But some Objective C knowledge is needed though, so this is a very basic question!

I am trying to use the FreeStreamer library , to play a shoutcast stream in my iOS app. I followed the basic steps (copied among others the needed file in my Xcode project) but how can I access to the FSAudioStream from my Swift class?

I tried this:

import UIKit

class FirstViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        let test = FSAudioStream

    }
    // ...
}

But the FSAudioStream class is not found, which doesn't surprise me. Should I add an extra import to my file? In that case, which one?

Answer 1

Ok, I found the solution from this Apple Developer page on mixing Swift and Objective C .

But there was something important: when setting the "Objective-C Bridging header" in the "Swift Compiler - Code Generation" section of the project, the path has to be set generally which in turns set value for both the "Debug" and "Release" keys.

So I set the "Swift Compiler - Code Generation" parameter to MyProject/MyProject-Header.h .

And in the MyProject/MyProject-Header.h file I added this:

#import "FSAudioStream.h"

And then there is nothing to import in the Swift file.

Problem solved!
