Background Music ??

Hello, I'm trying to play background music but it is not working.
</Edited>
I just wanna Know, does the simulator support the background music ? If there is a way then post some code or link.

Can anyone please help me on this.

Thanks, Ammad.

This is what I did.

•Add AVFoundation.framework

•Add aif audio file to project

•.h File

Code:

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>



@interface FirstViewController : UIViewController {
	AVAudioPlayer *playBackAudio;
		
}

-(IBAction)playBackAudio;

@end

•.m File

Code:

#import <AVFoundation/AVAudioPlayer.h>



@implementation FirstViewController


-(IBAction)playBackAudio
{

	[playBackAudio play];
}



/*
 // The designated initializer.  Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
 - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
 if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
 // Custom initialization
 }
 return self;
 }
 */


// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
	{
		NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/audio.aif", [[NSBundle mainBundle] resourcePath]]];
		
		NSError *error;
		playBackAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
		playBackAudio.volume = 0.1;
		playBackAudio.numberOfLoops = -1;
	}
	
	
		
    [super viewDidLoad];
}


/*
 // Override to allow orientations other than the default portrait orientation.
 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
 // Return YES for supported orientations
 return (interfaceOrientation == UIInterfaceOrientationPortrait);
 }
 */

- (void)didReceiveMemoryWarning {
	// Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];
	
	// Release any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
	// Release any retained subviews of the main view.
	// e.g. self.myOutlet = nil;
}


- (void)dealloc {
	[playBackAudio release];
	    [super dealloc];
}


@end

You can change the settings for loop and volume. I'm pretty new to this my self so be careful with what I provided but it worked for me. You could also probably simplify it as I set this up to have a button to start it. You could just add the play command in the view did load. Hope this helps, good luck.

Can you please explain that when -(IBAction)playBackAudio is called ? because it's an IBAction then , when any button will be pressed it will be called, I changed it to (void).
and will it support the the .mp3 extension ? because i'm using .mp3 and it is not working...

I think you should be able to remove the ibaction and just put the play command in the viewdidload. I used aif, didn't try mp3.

Ammad · 08-05-2010, 02:12 PM

yeah i did that , its working now , thanks for your help s8film40.

I also did it through threading like this:
- (void)viewDidLoad {
NSThread *thread = [[NSThread alloc] initWithTarget:self selector:@selector(backgroundMusic

object:nil];
[thread start];
...
...
...
}

-(void) backgroundMusic

id)sender
{

NSLog(@"I'm in ");
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"backgroundMusic.mp3" ofType:nil];

// Convert the file path to a URL.
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:filePath];

//Initialize the AVAudioPlayer.
audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:fileURL error:nil];

// Preloads the buffer and prepares the audio for playing.
[audioPlayer prepareToPlay];

//audioPlayer.currentTime = 0;

[audioPlayer play];

[filePath release];
[fileURL release];
}
