我正在尝试将音频重定向到AppRTC iOS example中的扬声器。
我试过了:
AVAudioSession* session = [AVAudioSession sharedInstance];
//error handling
BOOL success;
NSError* error;
//set the audioSession category.
//Needs to be Record or PlayAndRecord to use audioRouteOverride:
success = [session setCategory:AVAudioSessionCategoryPlayAndRecord
error:&error];
if (!success) NSLog(@"AVAudioSession error setting category:%@",error);
//set the audioSession override
success = [session overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker
error:&error];
if (!success) NSLog(@"AVAudioSession error overrideOutputAudioPort:%@",error);
//activate the audio session
success = [session setActive:YES error:&error];
if (!success) NSLog(@"AVAudioSession error activating: %@",error);
else NSLog(@"audioSession active");
没有错误,但是不起作用。我怎样才能解决这个问题?
最佳答案
我通过解决方案解决了。
只是听AVAudioSessionRouteChangeNotification
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didSessionRouteChange:) name:AVAudioSessionRouteChangeNotification object:nil];
并使用didSessionRouteChange选择器,如下所示:
- (void)didSessionRouteChange:(NSNotification *)notification
{
NSDictionary *interuptionDict = notification.userInfo;
NSInteger routeChangeReason = [[interuptionDict valueForKey:AVAudioSessionRouteChangeReasonKey] integerValue];
switch (routeChangeReason) {
case AVAudioSessionRouteChangeReasonCategoryChange: {
// Set speaker as default route
NSError* error;
[[AVAudioSession sharedInstance] overrideOutputAudioPort:AVAudioSessionPortOverrideSpeaker error:&error];
}
break;
default:
break;
}
}
