I want to play music even if the app goes in background. I checked all stackoverflow links but none of them worked. Please help need to do it today.

我使用了以下代码:-

NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"Day At The Beach"  ofType: @"mp3"];

NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath];

NSError *error;
playerTemp = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];
playerTemp.numberOfLoops = 0;
AudioSessionSetActive(true);
[playerTemp play];

在您的控制器视图中编写此代码确实像这样加载方法

write this code in your controller's view did load method like this

- (void)viewDidLoad
{
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"in-the-storm" ofType:@"mp3"]];
    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
    [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
    [[AVAudioSession sharedInstance] setActive: YES error: nil];
    [[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
    [audioPlayer play];
    [super viewDidLoad];
}
