(using AVFoundation.framework)
#import "AVFoundation/AVFoundation.h"
So I got a problem, I tried this code first in init method of my class (that is the one that is loaded first)
NSString* soundFilePath = [[NSBundle mainBundle] pathForResource:#"music" ofType:#"mp3"];
NSURL* soundFileURL = [NSURL fileURLWithPath:soundFilePath];
AVAudioPlayer* player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
player.numberOfLoops=-1;
[player play];
But it didn't work, than I decided to do it in thread:
in init method:
[NSThread detachNewThreadSelector:#selector(playMusic) toTarget:self withObject:nil];
and method itself:
-(void) playMusic {
NSString* soundFilePath = [[NSBundle mainBundle] pathForResource:#"music" ofType:#"mp3"];
NSURL* soundFileURL = [NSURL fileURLWithPath:soundFilePath];
AVAudioPlayer* player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
player.numberOfLoops=-1;
[player play];
}
it is declared in *.h file of course. It also didn't work.
I tried to debug, on line
}
of playMusic method the file is played for 2 or 3 seconds and then stops. It isn't played without debug. What is the problem?
The AVAudioPlayer will be deallocated immediately. You need to retain the player.
So make the AVAudioPlayer an instance variable of the class.

I have a timer that plays a sound when time reaches 0, but now I can't understand how to fire the event in order to play the sound if the app is in background mode or the screen is locked, What I found searching on the web was to set "UIBackgroundModes" in my .plist file, and add "audio" as array member.
UIBackgroundModes Array
Item0 String audio
Then add in the app delegate the following code:
NSError *setCategoryErr = nil;
NSError *activationErr = nil;
[[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error:&setCategoryErr];
[[AVAudioSession sharedInstance] setActive:YES error:&activationErr];
But the sound doesn't get played.. So I was wondering if it's possible to do something like this or I should change method
EDIT:
I imported:
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>
And this is the code I use to create the sound:
AVAudioPlayer *player;
NSString *soundFilePath = [NSString stringWithFormat:#"%#/clock.mp3",
[[NSBundle mainBundle] resourcePath]];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL
error:nil];
player.numberOfLoops = -1;
dispatch_async(dispatch_get_main_queue(), ^{
[player prepareToPlay];
});
Then to play it:
[player play];
I have just a snippet of Swift code but it should be easy to convert it to Obj-C
Try to use AVPlayerItem init with URL and then set AVPlayer init with PlayerItem
let assetUrl = self.nowPlayingItem!.associatedItem!.valueForProperty(MPMediaItemPropertyAssetURL) as! NSURL
let playerItem = AVPlayerItem(URL: assetUrl)
if let player = self.player {
player.replaceCurrentItemWithPlayerItem(playerItem)
} else {
self.player = AVPlayer(playerItem: playerItem)
}
self.player!.play()
and for this line of code:
NSString *soundFilePath = [NSString stringWithFormat:#"%#/clock.mp3",
[[NSBundle mainBundle] resourcePath]];
Have you tried:
[[NSBundle mainBundle] URLForResource:#"song" withExtension:#"mp3"];
// Create a new player item
NSURL *assetUrl = [nowPlayingItem valueForProperty:MPMediaItemPropertyAssetURL];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:assetUrl];
// Either create a player or replace it
if (self.player) {
[self.player replaceCurrentItemWithPlayerItem:playerItem];
} else {
self.player = [AVPlayer playerWithPlayerItem:playerItem];
}
nowPlayingItem is here a MPMediaItem but just replace NSURL *assetUrl = [nowPlayingItem valueForProperty:MPMediaItemPropertyAssetURL]; by NSURL *assetUrl =[[NSBundle mainBundle] URLForResource:#"song" withExtension:#"mp3"];
I'm trying to use AVAudioPlayer to play an mp3. Here is the code that I have:
- (void) playClip {
NSString *mp3File = [[NSBundle mainBundle] pathForResource:#"inFavor" ofType:#"mp3"];
AVAudioPlayer *avPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:mp3File] error:NULL];
[avPlayer play];
}
the name of the file that I'm referencing is "inFavor.mp3"
I'm a bit new to Objective-C so I'm not exactly sure why this isn't working. I'm using Xcode 5.
Make the AVAudioPlayer a property of the class so that it is not released when the function goes out of scope.
#property (strong, nonatomic) AVAudioPlayer* avPlayer;
Then initialize with
self.avPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:mp3File] error:NULL];
try this code, you need to check the error. paste the log you are getting in error
NSError *error;
NSString *path = [[NSBundle mainBundle] pathForResource:#"inFavor"
ofType:#"mp3"];
AVAudioPlayer* avPlayer =
[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path]
error:&error];
if (error) {
NSLog(#"failed playing error: %#", error);
}else{
//avPlayer.delegate = self;
[avPlayer play];
}
I want to implement a player that plays sounds and/or music. I have these two methods:
-(void)playSound:(int)soundIndex
{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[SoundFxFilenameArray objectAtIndex:soundIndex] ofType:#"mp3"]];
if(FxPlayer)
{
[FxPlayer release];
FxPlayer = nil;
}
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategorySoloAmbient error:nil];
FxPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[FxPlayer play];
}
-(void)playMusic:(NSString *)filename
{
NSURL *url = [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:filename ofType:#"mp3"]];
if(MusicPlayer)
{
[MusicPlayer release];
MusicPlayer = nil;
}
MusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
[MusicPlayer play];
}
Now, [[SoundPlayer sharedManager] playSound:FXIndex_Default] works just fine. When I try to play music though, [[SoundPlayer sharedManager] playMusic:#"music_file_name_here" just doesn't do anything. Note that both the sound file and the music file are of the same format (mp3).
Also, the "sharedInstance" is because I implemented the singleton pattern for this audio player.
Any pointers or ideas on what is so wrong in my code so that I can play sounds but not music?
Use fileURLWithPath instead of URLWithString in playMusic:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:filename ofType:#"mp3"]];
URLWithString expects a complete URL such as "file://path/to/file.mp3" as argument, fileURLWithPath expects just a file path.
I am trying to setup a stopwatch alarm that is enabled via UISwitch. I want the alarm to be triggered after an x amount of secs after the timer has started. I have an ivar int variable (timerCount) that holds the amount of secs that has passed and I want to play a sound based on that ivar. When the timer begins and I enable the switch I would hope that the player would fire at 10 secs, but that is not the case. I know the "if statement" is the culprit because when I remove it the AVPlayer will play the wav file when the switch is enabled. I just need another set of eyeballs to look at this and figure out what I missed.
Here is the code snippet:
- (IBAction)timerSound{
if (voiceSwitch.on){
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"horn"
ofType:#"wav"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath];
player = [[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error: nil];
if (timerCount == 10)
[self.player play];
}
else {
[self.player stop];
}
}
You are looking for playAt:.
Example based on yours –
- (IBAction)valueChanged:(id)sender {
UISwitch *aSwitch = (UISwitch*)sender;
if ( aSwitch.on ) {
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"horn"
ofType:#"wav"];
NSURL *fileURL = [NSURL fileURLWithPath:soundFilePath];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL
error:nil];
[audioPlayer playAtTime:(audioPlayer.deviceCurrentTime + 3)];
} else {
[audioPlayer stop];
}
}
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag {
[self.theSwitch setOn:NO animated:YES];
[player release];
}
in my app i use AudioToolbox framework and i need to play a loop can i ?
this is the AVAudioplayer code that goes slowly with 2 touches simultaneously
- (AVAudioPlayer *)getNoteFromFilename:(NSString *)name andoftype:(NSString *)type{
NSString *soundPath = [[NSBundle mainBundle] pathForResource:name
ofType:type];
NSURL *fileURL = [NSURL fileURLWithPath:soundPath];
AVAudioPlayer *note = [[[AVAudioPlayer alloc] initWithContentsOfURL:fileURL
error:nil] autorelease];
return note;
}
in the viewdidload
ViewDidLoad {
self.Note = [self getNoteFromFilename:#"Note" andoftype:#"wav"];
}
calling it by this in IBAction :
[Note prepareToPlay];
[Note play];
NB: i have retaind all the button and the AVAudioPlayer
Use AVAudioPlayer instead. There you can easily loop using the numberOfLoops property.
