所以我有我的收音机应用程序的简单代码:

 -(IBAction)europaPlus:(id)sender{

        NSLog(@"EuropaPlus work");

        if (clicked ==  0) {

            clicked = 1;

            NSString *urlAddress = @"http://cast.europaplus.ua/europaplus.aac";

            NSURL *urlStream = [NSURL URLWithString:urlAddress];

            radioPlus = [[AVPlayer alloc] initWithURL:urlStream];

            [radioPlus play];}

        else {

            NSLog(@"EuropaPlus not work");

            [radioPlus release];

            clicked = 0;

        }
}

此外,我仅将 AVPLAYER 用于 URL 连接,但如何在 MAC OS 中为 AVPlayer 进行音量控制。我知道 IOS 中的 MPMVolumeControl,但我有 mac os 项目。谢谢。

player = [[AVAudioPlayer alloc] initWithContentsOfURL:
          [NSURL fileURLWithPath:resourcePath] error:&err];
player.delegate = self;
[player play];
player.volume=.number;
player.numberOfLoops=-number;

-(IBAction)slidervaluechanged {

     player.volume=slider.value; 

}
