在后台iOS应用中播放音乐

Question

In my code:

- (void) viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSURL* musicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"www/media/BlueZedEx" ofType:@"mp3"]];

AVAudioPlayer *click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];

NSLog(@"goldenace launchOptions = %@", musicFile);
click.delegate = self;
click.numberOfLoops = -1;
[click play];

}

But nothing music play when I run my app in simulator. Please help!

Answer 1

use this for Playing Background Audio:

 [[AVAudioSession sharedInstance] setDelegate: self];
 NSError *setCategoryError = nil;
 [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: &setCategoryError];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

Answer 2

This

www/media/BlueZedEx

is not a filename. It needs to be a filename of a audio file inside your project (drag and drop)
