How would I play a sound when my iOS app launches; should I use an AVPlayer to play an mp3 file?


In didFinishLaunchingWithOptions: use below code to play audio
NSURL *url = [NSURL URLWithString:pathToYourFile];
AVPlayer *audioPlayer = [[AVPlayer alloc] initWithURL:url];
[audioPlayer play];

How to play mp3 file from url in iOS?

I am trying to play mp3 file located somewhere on remote server.I have the url of that music fileI have tried it playing it using AVAudioPlayer or AVPlayer but i am not able to play the mp3 file.Please tell me how can i play the mp3 file.
code to play music:
NSString *aSongURL = [NSString stringWithFormat:#"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];
// NSLog(#"Song URL : %#", aSongURL);
AVPlayerItem *aPlayerItem = [[AVPlayerItem alloc] initWithURL:[NSURL URLWithString:aSongURL]];
AVPlayer *anAudioStreamer = [[AVPlayer alloc] initWithPlayerItem:aPlayerItem];
[anAudioStreamer play];
// Access Current Time
NSTimeInterval aCurrentTime = CMTimeGetSeconds(anAudioStreamer.currentTime);
// Access Duration
NSTimeInterval aDuration = CMTimeGetSeconds(anAudioStreamer.currentItem.asset.duration);
Please tell me how do i do it?

Try Below Code.
NSURL *url = [NSURL URLWithString:#"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];
self.playerItem = [AVPlayerItem playerItemWithURL:url];
self.player = [AVPlayer playerWithPlayerItem:playerItem];
self.player = [AVPlayer playerWithURL:url];
[self.player play];

Try use AVAudioPlayer, see below
NSString *aSongURL = [NSString stringWithFormat:#"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL URLWithString:aSongURL] error:nil];
[audioPlayer play];
Hope it works.

iOS: playing sound while other apps are playing

in my app i need to play alert sounds.
if another app (like spotify) is running, when i run my code it stops the music from spotify whenever the alert sound plays.
is there anyway to avoid this?
this is my play sound code:
- (void)playSendSound
{
NSString* path;
NSURL* url;
path = [[NSBundle mainBundle] pathForResource:#"soundBit" ofType:#"aif"];
url = [NSURL fileURLWithPath:path];
player = nil;
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
[player play];
}

You are using AVAudioPlayer to play your alert sound and sure it will stop whatever music that is playing.
Modify your code to the following:
NSString* path;
NSURL* url;
path = [[NSBundle mainBundle] pathForResource:#"soundBit" ofType:#"aif"];
url = [NSURL fileURLWithPath:path];
player = nil;
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:NULL];
NSError *error = nil;
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryAmbient error:&error];
[player play];
This should prevent the sound that is playing to stop when you play your alert sound.
Hope this helps.

MPMusicPlayerController live streaming

I am developing an application that plays a live HTTP web radio streaming (.pls, .mp3 ...). Can i use the MPMusicPlayerController to play the stream ? Thaks.

I don't think you can play streaming audio using MPMusicPlayerController. You should look at AVPlayer.
NSURL *url = [NSURL URLWithString:url];
AVURLAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithAsset:asset];
AVPlayer *audioPlayer = [AVPlayer playerWithPlayerItem:playerItem];
[audioPlayer play];

How perform streaming of .m4a song file with AVAudioPlayer?

I'm trying to play this song from itunes store while I'm downloading it
Why the code below doesn't play?
NSLog(#"start");
NSURL *songUrl = [NSURL URLWithString:#"http://a1804.phobos.apple.com/us/r1000/064/Music/v4/9b/b3/c7/9bb3c7dc-a06f-f18c-3e41-2ce1e36f73b4/mzaf_7432104896053262141.aac.m4a"];
NSError* errorVar = nil;
AVAudioPlayer* song = [[AVAudioPlayer alloc] initWithContentsOfURL:songUrl error:&errorVar];
[song prepareToPlay];
[song play];

I think you have to use AVPlayer instead of AVAudioPlayer.
Apple documentation suggests AVAudioPlayer is used for playback of audio data from a file or memory. AVPlayer works equally well with local and remote media files.
self.player = [AVPlayer playerWithURL:<#Live stream URL#>];
[player addObserver:self forKeyPath:#"status" options:0 context:&PlayerStatusContext];
Refer Apple Docs for more info.

You can do
// soundUrl can be a remote url, don't need to be a file url
NSData *data = [NSData dataWithContentsOfURL:soundUrl];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:data error:nil];
