да, вы можете использовать AVAudioPlayer в App Delegate.
Что вам нужно сделать, это: - В файле appDelegate.h:it.
В appDelegate.m
файле do: -
Добавьте эти строки в метод FinishLaunching did
NSError *setCategoryError = nil;
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:&setCategoryError];
// Create audio player with background music
NSString *backgroundMusicPath = [[NSBundle mainBundle] pathForResource:@"SplashScreen" ofType:@"wav"];
NSURL *backgroundMusicURL = [NSURL fileURLWithPath:backgroundMusicPath];
NSError *error;
_backgroundMusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:&error];
[_backgroundMusicPlayer setDelegate:self]; // We need this so we can restart after interruptions
[_backgroundMusicPlayer setNumberOfLoops:-1]; // Negative number means loop forever
Теперь реализуйте методы делегата
#pragma mark -
#pragma mark AVAudioPlayer delegate methods
- (void) audioPlayerBeginInterruption: (AVAudioPlayer *) player {
_backgroundMusicInterrupted = YES;
_backgroundMusicPlaying = NO;
}
- (void) audioPlayerEndInterruption: (AVAudioPlayer *) player {
if (_backgroundMusicInterrupted) {
[self tryPlayMusic];
_backgroundMusicInterrupted = NO;
}
}
- (void)tryPlayMusic {
// Check to see if iPod music is already playing
UInt32 propertySize = sizeof(_otherMusicIsPlaying);
AudioSessionGetProperty(kAudioSessionProperty_OtherAudioIsPlaying, &propertySize, &_otherMusicIsPlaying);
// Play the music if no other music is playing and we aren't playing already
if (_otherMusicIsPlaying != 1 && !_backgroundMusicPlaying) {
[_backgroundMusicPlayer prepareToPlay];
if (soundsEnabled==YES) {
[_backgroundMusicPlayer play];
_backgroundMusicPlaying = YES;
}
}
}
