Я играю в Apple Music из своего приложения, код музыкального проигрывателя Apple выглядит так:
-(void) submitAppleMusicTrackWithProductID: (NSString *) productID // productID in US is the last numbers after i= in the share URL from Apple Music
{
[SKCloudServiceController requestAuthorization:^(SKCloudServiceAuthorizationStatus status) {
NSLog(@"status is %ld", (long)status);
SKCloudServiceController *cloudServiceController;
cloudServiceController = [[SKCloudServiceController alloc] init];
[cloudServiceController requestCapabilitiesWithCompletionHandler:^(SKCloudServiceCapability capabilities, NSError * _Nullable error) {
NSLog(@"%lu %@", (unsigned long)capabilities, error);
if (capabilities >= SKCloudServiceCapabilityAddToCloudMusicLibrary || capabilities==SKCloudServiceCapabilityMusicCatalogPlayback)
{
NSLog(@"You CAN add to iCloud!");
[[MPMediaLibrary defaultMediaLibrary] addItemWithProductID:productID completionHandler:^(NSArray<__kindof MPMediaEntity *> * _Nonnull entities, NSError * _Nullable error)
{
NSLog(@"added id%@ entities: %@ and error is %@", productID, entities, error);
NSArray *tracksToPlay = [NSArray arrayWithObject:productID];
[[MPMusicPlayerController applicationMusicPlayer] setQueueWithStoreIDs:tracksToPlay];
[[MPMusicPlayerController applicationMusicPlayer] stop];
[[MPMusicPlayerController applicationMusicPlayer] play];
self.isTrackChangedByNextPreviousButton = NO;
[[NSNotificationCenter defaultCenter]removeObserver:self name:MPMusicPlayerControllerNowPlayingItemDidChangeNotification object:nil];
[[NSNotificationCenter defaultCenter]removeObserver:self name:MPMusicPlayerControllerPlaybackStateDidChangeNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(handleTrackChanged:)
name:MPMusicPlayerControllerNowPlayingItemDidChangeNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(handlePlaybackStateChanged:)
name:MPMusicPlayerControllerPlaybackStateDidChangeNotification
object:nil];
[[MPMusicPlayerController applicationMusicPlayer] beginGeneratingPlaybackNotifications];
[[MPMusicPlayerController applicationMusicPlayer] setRepeatMode: MPMusicRepeatModeNone];
}];
}
else
{
NSLog(@"Blast! The ability to add Apple Music track is not there. sigh.");
}
}];
}];
}
-(void)handleTrackChanged:(id )notification
{
if (!self.AppleMusicPreviuosTrack)
{
self.AppleMusicPreviuosTrack = [[Tracks alloc] init];
}
if (self.AppleMusicPreviuosTrack.trackId == self.CurrentTrack.trackId && [MPMusicPlayerController applicationMusicPlayer].currentPlaybackRate == 0 && !self.isSongChangedManually)
{
self.isSongChangedManually = YES;
[self FilterArtistsTracks:@"next" :^(Tracks *track, NSError *err)
{
}];
}
else
{
if ([[MPMusicPlayerController applicationMusicPlayer] currentPlaybackRate]==1)
{
self.AppleMusicPreviuosTrack.trackId = self.CurrentTrack.trackId;
[[NSNotificationCenter defaultCenter] postNotificationName:kTrackChanged object:nil];
//Delay execution of my block for 20 seconds.
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 30 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
self.isSongChangedManually = NO;
});
}
}
}
-(void)handlePlaybackStateChanged:(id )notification
{
NSLog(@"handle_PlaybackStateChanged");
[[NSNotificationCenter defaultCenter] postNotificationName:kDidTrackPlaybackStatus object:nil];
if ([MPMusicPlayerController applicationMusicPlayer].currentPlaybackRate>0)
{
[self.playerMenuView.playpauseButton setImage:[UIImage imageNamed:@"pause"] forState:UIControlStateNormal];
}
else
{
[self.playerMenuView.playpauseButton setImage:[UIImage imageNamed:@"play"] forState:UIControlStateNormal];
}
}
который отлично работает. Теперь я хочу управлять треком с экрана блокировки, для этого я сделал следующий код в viewWillAppear
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[APP_DELEGATE becomeFirstResponder];
а метод remoteControlReceivedWithEvent записан в файле AppDelegate следующим образом:
-(void)remoteControlReceivedWithEvent:(UIEvent *)event
{
switch (event.subtype)
{
case UIEventSubtypeRemoteControlTogglePlayPause:
[APP_DELEGATE PlayPauseMusic:nil];
//[streamer pause];
break;
case UIEventSubtypeRemoteControlPlay:
[APP_DELEGATE PlayPauseMusic:nil];
//[streamer start];
break;
case UIEventSubtypeRemoteControlPause:
[APP_DELEGATE PlayPauseMusic:nil];
//[streamer pause];
break;
case UIEventSubtypeRemoteControlStop:
[APP_DELEGATE PlayPauseMusic:nil];
//[streamer stop];
break;
case UIEventSubtypeRemoteControlNextTrack:
[APP_DELEGATE next:nil];
break;
case UIEventSubtypeRemoteControlPreviousTrack:
[APP_DELEGATE previous:nil];
break;
default:
break;
}
}
Примечание. remoteControlReceivedWithEvent срабатывает каждый раз, когда iTunes дорожек воспроизводятся AVPlayer ИЛИ Spotify дорожек воспроизводятся с помощью Spotify iOS SDK .
Но тот же код не срабатывает при воспроизведении треков Apple Music с помощью -
[MPMusicPlayerController applicationMusicPlayer]
or
[MPMusicPlayerController systemMusicPlayer]
любая помощь будет оценена. Спасибо
