是否可以在不停止iPod音乐的情况下播放声音？

Question

是否可以在不停止iPod音乐的情况下在应用中播放声音？

现在我正在使用以下内容,但它会停止iPod音乐

soundPath =[[NSBundle mainBundle] pathForResource:@"mySound" ofType:@"mp3"];
soundURL = [NSURL fileURLWithPath:soundPath];   
mySound = [[AVAudioPlayer alloc] initWithContentsOfURL:soundURL error:nil];
[mySound prepareToPlay];

然后

[mySound play];

Answer 1

是的,你可以使用以下代码

// setup session correctly
AVAudioSession *audiosession = [AVAudioSession sharedInstance];
[audiosession setCategory:AVAudioSessionCategoryPlayback error:nil];
OSStatus propertySetError = 0;

UInt32 mixingAllow = true;
propertySetError = AudioSessionSetProperty ( kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof (mixingAllow),&mixingAllow);

NSError *error = nil;
[audiosession setActive:YES error:&error];

// play sound
NSURL *url = [NSURL fileURLWithPath:filePath];
AVAudioPlayer *audioplayer = [[[AVAudioPlayer alloc] initWithContentsOfURL:url error:&;error]autorelease];

Answer 2

是的,或者只是

AVAudioSession *audiosession = [AVAudioSession sharedInstance];
[audiosession setCategory:AVAudioSessionCategoryAmbient error:nil];
