NSURL *url = [NSURL URLWithString:[urlstr stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
NSData *songData=[NSData dataWithContentsOfURL:url];
self.audioPlayer = [[AVAudioPlayer alloc] initWithData:songData error:nil];

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.
I am trying to get itunes song previews to play in my app. I have found some other questions like this but none of the solutions have worked for me. I am already signed up with the Affiliate program that apple has. Here are some of the things I have tried:
This got me the itunes preview URL that I am trying
NSUInteger numberOfResults = 200;
NSString *searchString = #"AC/DC";
NSString *encodedSearchString = [searchString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *finalSearchString = [NSString stringWithFormat:#"https://itunes.apple.com/search?term=%#&entity=song&limit=%u",encodedSearchString,numberOfResults];
NSURL *searchURL = [NSURL URLWithString:finalSearchString];
dispatch_queue_t iTunesQueryQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, kNilOptions);
dispatch_async(iTunesQueryQueue, ^{
NSError *error = nil;
NSData *data = [[NSData alloc] initWithContentsOfURL:searchURL options:NSDataReadingUncached error:&error];
if (data && !error) {
NSDictionary *JSON = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
NSArray *array = [JSON objectForKey:#"results"];
NSLog(#"Array is:%#",array);
}
});
This plays nothing
NSURL *url = [NSURL URLWithString:[_backgroundPreviewList objectAtIndex:randomPreview]];
NSData *_objectData = [NSData dataWithContentsOfURL:url];
NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithData:_objectData error:&error];
audioPlayer.numberOfLoops = 0;
audioPlayer.volume = 1.0f;
[audioPlayer prepareToPlay];
if (audioPlayer == nil)
{
NSLog(#"%#", [error description]);
}
else
{
[audioPlayer play];
}
This also played nothing
AVPlayer* aPlayer = [AVPlayer playerWithURL:url];
[aPlayer play];
I even tried this that didn't work
MPMoviePlayerController* player = [[MPMoviePlayerController alloc] initWithContentURL:url];
[player play];
If anyone has done this can they let me know how to play the songs.
This is released and working using MPMoviePlayerController, which I believe is the recommended approach for the streaming previews. Depending on what you are trying to do, you might have to work through some steps to enable play in the background. Good luck. p.s. if you get the AVPlayer working there are more docs available with solutions for background play see Technical QA doc 1668 from Apple
{
self.songPreview = [[MPMoviePlayerController alloc] init];
self.songPreview.movieSourceType = MPMovieSourceTypeStreaming;
/// set your URL from wherever you are getting it
[self.songPreview setContentURL:self.previewArtWorkButton.currentPreviewURL];
[self.view addSubview:self.songPreview.view];
/// i have set this next property to hidden because i am controlling volume and play programmatically
[self.songPreview.view setHidden:YES];
/// i have this next property set to No because I am using another trigger to play the /// song and not auto play after the buffering has completed
[self.songPreview setShouldAutoplay:NO];
[self.songPreview prepareToPlay];
}
/// later i call the play method
[self.songPreview play];
I have got it working. One of the things I changed is I took that specific class out of ARC to make sure things were staying around. Here is the code I am using now
NSURL *url = [NSURL URLWithString:#"URL"];
AVPlayerItem* playerItem = [AVPlayerItem playerItemWithURL:url];
NSLog(#"The url is: %#", url);
if(_player)
{
[_player release];
}
_player = [[AVPlayer playerWithPlayerItem:playerItem] retain];
[_player play];
_player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
Where _player is an AVPlayer object
I have two pieces of code:
Code 1 - This is playing a music file via the in-ear speaker:
NSString *tileDirectory = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"8Ocean.mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:tileDirectory];
NSError *error=nil;
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];
if(!error)
{
[self.audioPlayer prepareToPlay];
UInt32 sessionCategory = kAudioSessionCategory_PlayAndRecord;
AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(sessionCategory), &sessionCategory);
[self.audioPlayer play];
}
else
{
NSLog(#"%#",error.localizedDescription);
}
Code 2- This is playing a music file during a phone call (is routed to in-ear or speaker phone depending on user setting during the phone call)
NSString *tileDirectory = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"8Ocean.mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:tileDirectory];
NSError *error=nil;
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error];
if(!error)
{
[self.audioPlayer prepareToPlay];
self.audioPlayer.volume=10.0;
UInt32 sessionCategory = kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride);
[self.audioPlayer play];
}
else
{
NSLog(#"%#",error.localizedDescription);
}
My issue is:
Code 1 and 2 work well independently. However, after using code 1, code 2 will not work at all (unless the app is killed and restarted)
I have tried everything I can think of but cannot work out where the problem is from.
Your app needs to handle audio session interruptions from phone calls in order for audio processing not to be killed for your app.
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];
I've an AVAudioPlayer with a MP3-file. But before playing, you'll hear a hitch.
This is my code:
NSString *geluid = [NSString stringWithFormat:#"RG_%#", nummer];
NSString *path = [[NSBundle mainBundle] pathForResource:geluid ofType:#"mp3"];
AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate=self;
[theAudio prepareToPlay];
[theAudio play];
NSURL *url = [NSURL fileURLWithPath:path];
avplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[avplayer prepareToPlay];
[avplayer play];
For example: You hear "Ssstop here", in stead off "Stop here".
Please help me to fix it.
Is this code running two AVAudioPlayer instances at the same time ?
Why are you using both avplayer and theAudio ?
From looking at it it looks like you should get rid of one of them...
