AVAudioPlayer doesn't start playing in background

Question

I am using AVAudioPlayer and NSFileHandle to do audio streaming. The basic idea is that I save the streaming audio data to the device with file sys

Answer 1

Please use this code in - (void)applicationDidEnterBackground:(UIApplication *)application

UIApplication *app = [UIApplication sharedApplication];
UIBackgroundTaskIdentifier bgTask = 0;

bgTask = [app beginBackgroundTaskWithExpirationHandler:^{ 
[app endBackgroundTask:bgTask]; 
}];
AudioSessionSetActive(false);

and use this code in - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

AudioSessionInitialize (NULL,NULL,NULL,NULL);
UInt32 sessionCategory = kAudioSessionCategory_MediaPlayback;
AudioSessionSetProperty (kAudioSessionProperty_AudioCategory,sizeof (sessionCategory),&sessionCategory);
AudioSessionSetActive(true);

hope this helps.
