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'm on latest Xcode version. I'm using following code to restart my background music. But these codes are not restarting the background music.
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"game" ofType:#"wav"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
[player stop];
player.currentTime = 0;
[player play];
To use AVAudioPlayer, you need a strong reference to it. Try to set the player as a property of your controller, then use [self.player play]
Declare AVAudioPlayer into .h file.
I am having trouble with my audio.
here is the code:
AVAudioPlayer *audioPlayer;
NSString *audioPath = [[NSBundle mainBundle]pathForResource:#"Cheering" ofType:#"mp3"];
NSURL *audioURL = [NSURL fileURLWithPath:audioPath];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:nil];
[audioPlayer play];
It will not play like this. The code steps through just fine but no audio. If I put a break on the last line and then step through it plays properly. I have tried everything I can to get this to work but have no clue where to go from here.
It is acting like it needs a delay before the play command.
Try this Sure It will Works
NSURL* url = [[NSBundle mainBundle] URLForResource:#"Cheering" withExtension:#"mp3"];
NSAssert(url, #"URL is valid.");
NSError* error = nil;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
if(!audioPlayer)
{
NSLog(#"Error creating player: %#", error);
} else
{
[audioPlayer play];
}
Did you try
[audioPlayer prepareToPlay]
before you actually try to play it?

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...
- (void)viewDidLoad {
[super viewDidLoad];
[audioPlayer stop];
NSString *Path = [[NSBundle mainBundle] pathForResource:#"Keep the Shoes Moving" ofType: #"m4a"];
NSURL *URL = [[NSURL alloc] initFileURLWithPath: Path];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:URL error:&error];
audioPlayer.numberOfLoops = -1;
[audioPlayer play];
[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications]; }
What happens with this is every time I navigate back to this viewController it plays another track. So then I have two tracks playing over each other. How would I get this to stop??
Store your AVAudioPlayer instance in a property and call it’s stop method when you want it to stop playing.
