I want to play mp3 file placed in resources as code is given below,
NSString *st=#"alarm_1.mp3";
NSLog(st);
NSURL* musicFile = [NSURL fileURLWithPath:st];
AVAudioPlayer *click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
//AVAudioPlayer *click1=[[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL URLWithString:#"alarm_1.mp3"]];
[click prepareToPlay];
[click play];
[click release];
but unfortunately i cant hear the sound
please help
I don't think your file name is right. Try this syntax:
NSURL *clickURL = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]initWithContentsOfURL:clickURL error:nil];
I had a similar problem due to ARC. Instead of defining the AVAudioPlayer in the same method you are using it, you should should have an instance variable somewhere else, such as the UIViewController. This way ARC doesn't auto release this object and audio can play.
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/alarm_1.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;
[audioPlayer play];
This is answer

I currently have this code that works. I have two questions.
How do I set the directory to "Supporting Files"?
How do I use a variable in the file name? I need it to pull an mp3 of any animal based on a variable.
- (void)playAnimal{
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/Sheep.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = 0;
if (audioPlayer == nil)
NSLog([error description]);
else
[audioPlayer play];
}
I'm very new to Objective-C, so a lot of syntax things are new to me as well as general methods. Thanks for your patience!
Use the following:
NSString *path = [[NSBundle mainBundle] pathForResource:#"Sheep" ofType:#"mp3"]];
NSURL *url = [NSURL fileURLWithPath:path];
When your resources are copied to the bundle, they do not retain their directory structure. Just identify the resource by name and it will find the path for it.
Just as an FYI, the following works, as well:
NSString *path = [[NSBundle mainBundle] pathForResource:#"Sheep.mp3" ofType:#""]];
NSURL *url = [NSURL fileURLWithPath:path];
This may be useful if you have a set of resources logically grouped together in a plist and you are programmatically reading those out. For example:
// reference to a dictionary with the entry 'Sheep.mp3'
NSString *resourceName = [dictionary objectForKey:item1];
NSString *path = [[NSBundle mainBundle] pathForResource:resourceName ofType:#""]];
NSURL *url = [NSURL fileURLWithPath:path];
I had code in a old sdk 3.0 project of mine that is not working with the new sdk. I have copied the code in a very simple project (just a uivue project and I put the sound code in onload) to make sure nothing else I did is messing it up.
I'm getting a error code -46, Domain NSOSStatusErrorDomain
code
- (void)viewDidLoad
{
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"EvilDrop-2.mp3",
[[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.volume=1.0;
audioPlayer.numberOfLoops= 0;
[audioPlayer play];
audioPlayer.delegate = self;
}
That's because you're not using -[NSString stringWithFormat: correctly. However, you don't need that method.
Try this code:
NSURL *myURL;
myURL = [[NSBundle mainBundle]
URLForResource:#"MyFile"
withExtension:#"mp3"];
Heres what I have:
-(void)awakeFromNib {
NSString *path = [[NSBundle mainBundle] pathForResource:***AUDIOFILE*** ofType:#"mp3"];
AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path]
error:NULL];
[theAudio play];
The coding is fine, except I don't know how to call out my resource for the sound to play or whatever.
If your Audio file is inside your project then you just need to give Filename without extension in place of *AUDIOFILE*.
It is good practice to use [theAudio prepareToPlay] method for AVAudioPlayer.
i wanna play music with MPMusicPlayerController.
MPMediaItem * mediaItem = [];
MPMediaItemCollection *songs;
NSArray * array = [NSArray arrayWithObjects:mediaItem, nil];
songs = [MPMediaItemCollection collectionWithItems:array];
[[MPMusicPlayerController iPodMusicPlayer] setQueueWithItemCollection:songs];
i don't know how to give mediaItem, and i have a mp3 file.
Help me. thank you!
No, the MPMusicPlayerController will only play music from the Media Library (That's why its located in the MP/MediaPlayer framework) You'll need to use the AVAudioPlayer or the AVPlayer class. A bit more work implementing that unfortunately.
Something along the lines of this should get you started:
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/audiofile.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;
if (audioPlayer == nil)
NSLog([error description]);
else
[audioPlayer play];
My Problem is the following. I got this code and i guess a corrupt NSURL since the AVAudioPlayer is nil after initializing:
NSString *dummyURLString = #"http://a825.phobos.apple.com/us/r2000/005/Music/d8/a8/d2/mzi.jelhjoev.aac.p.m4p";
NSError *error;
NSURL *url = [NSURL URLWithString:dummyURLString];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[player play];
Any suggestions what is going wrong here?
The &error shows this:
Error Domain=NSOSStatusErrorDomain Code=-43 "Operation could not be completed. (OSStatus error -43.)"
AVAudioPlayer only works with local URL's. It must be a File URL (file://)
See Apple's Technical Q&A QA1634
I tried this first but got error 2003334207:
NSData *soundData = [NSData dataWithContentsOfURL:URL];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithData:soundData error:&error];
Seems that AVAudioPlayer really wants a file. So I put the data into a file first:
NSURL *url = [NSURL URLWithString:#"http://a825.phobos.apple.com/us/r2000/005/Music/d8/a8/d2/mzi.jelhjoev.aac.p.m4p"];
NSData *soundData = [NSData dataWithContentsOfURL:url];
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent:#"sound.caf"];
[soundData writeToFile:filePath atomically:YES];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL
fileURLWithPath:filePath] error:NULL];
NSLog(#"error %#", error);
Instead of using the AVAudioPlayer you can use the AVPlayer. The AVPlayer works as well with remote URLs
