Is there an easy way to load, play and control an mp3 file from cocoa? Tried googling it, but, as all things apple, i get messy results and have no idea where to start. As i understand, there's and NSSound, but it has lots of limitations and then there's CoreAudio, but it's very difficult. So can someone point me in a right direction with this? Thanks.

Use AVFoundation! According to apple, it has been integrated with Mac OS X Lion (I think), so.. Here is how to play mp3 painlessly:
1- link the AVFoundation Framework.
2- import it wherever you want to play your awesome mp3
#import <AVFoundation/AVFoundation.h>
3- Add an audioPlayer instance variable to play the sound (That's how I like to do it, at least)
@interface WCMainWindow : ... {
...
AVAudioPlayer* audioPlayer;
}
4- In you init, make sure you initialize your audioPlayer:
NSString* path = [[NSBundle mainBundle] pathForResource:@"myFile" ofType:@"mp3"];
NSURL* file = [NSURL fileURLWithPath:path];
// thanks @gebirgsbaerbel
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:file error:nil];
[audioPlayer prepareToPlay];
5- Play your awesome Mp3!!
if ([audioPlayer isPlaying]) {
[audioPlayer pause];
} else {
[audioPlayer play];
}
Finally, credit goes to this guy.
import Cocoa
import AVFoundation
class ViewController: NSViewController {
var audio = AVAudioPlayer()
override func viewDidLoad() {
super.viewDidLoad()
let play = Bundle.main.path(forResource: "A" , ofType: "mb3")
do{
audio = try AVAudioPlayer(contentsOf: URL(fileURLWithPath: play!))
}
catch{
print(error)
}
}
@IBAction func button(_ sender: Any)
{
audio.play()
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
}
