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音乐的情况下播放应用程序中的声音？

现在，我使用以下，但它停止的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，你可以使用下面的代码

// 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，或者只是

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