remoteControlReceivedWithEvent llamó al dispositivo iOS 7.0 pero no a iOS 8.0
Tengo una aplicación que reproduce audio en segundo plano. Estoy tratando de corregir un error donde los controles de audio (reproducción / pausa), en la pantalla de inicio (etc.), NO funcionan en iOS 8.0+ pero funcionan FINE en iOS 7.0. He estado investigando tratando de descubrir cuál es el problema y he estado vacío. Cualquier idea sería muy apreciada. Aquí está lo que tengo en su lugar.
En la configuración del proyecto: me he asegurado de queUIBackgroundModes
se establece enaudio
.
En AppDelegate.h: tengo un miembro para elAVAudioSession* session;
así como elAVPlayer *audioPlayer;
En el AppDelegate.m:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
self.session = [AVAudioSession sharedInstance];
NSError* error = NULL;
[self.session setCategory:AVAudioSessionCategoryPlayback error:&error];
[self.session setActive:YES error:&error];
if (error) {
NSLog(@"AVAudioSession error: %@", [error localizedDescription]);
}
En el AudioPlayerViewController.m
- (void)viewDidLoad {
//Get the Audio
NSURL *url = [NSURL URLWithString:self.audioUrl];
AVAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
//Setup the player
self.playerItem = [AVPlayerItem playerItemWithAsset:asset];
appDelegate.audioPlayer = [AVPlayer playerWithPlayerItem:self.playerItem];
//Setup the "Now Playing"
NSMutableDictionary *mediaInfo = [[NSMutableDictionary alloc]init];
[mediaInfo setObject:self.title forKey:MPMediaItemPropertyTitle];
[mediaInfo setObject:self.artist forKey:MPMediaItemPropertyArtist];
[mediaInfo setObject:self.album forKey:MPMediaItemPropertyAlbumTitle];
[mediaInfo setObject:[NSNumber numberWithDouble:duration ] forKey:MPMediaItemPropertyPlaybackDuration];
[[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:mediaInfo];
}
// Process remote control events
- (void) remoteControlReceivedWithEvent:(UIEvent *)event {
NSLog(@"AudioPlayerViewController ... remoteControlReceivedWithEvent top ....subtype: %d", event.subtype);
if (event.type == UIEventTypeRemoteControl) {
switch (event.subtype) {
case UIEventSubtypeRemoteControlTogglePlayPause:
[self togglePlayPause];
break;
case UIEventSubtypeRemoteControlPause:
[self doPause];
break;
case UIEventSubtypeRemoteControlStop:
[self doPause];
break;
case UIEventSubtypeRemoteControlPlay:
[self doPlay];
break;
case UIEventSubtypeRemoteControlPreviousTrack:
[self nextOrPrevTrack];
break;
case UIEventSubtypeRemoteControlNextTrack:
[self nextOrPrevTrack];
break;
default:
break;
}
}
}
-(void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self becomeFirstResponder];
}
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[[UIApplication sharedApplication] endReceivingRemoteControlEvents];
[self resignFirstResponder];
