iPhone play, pause and stop playing music

This is the small iPhone SDK example that will show you how to play, pause and stop the music on button clicks.

You can create the example in view based application. But for playing the music you need to add AVFoundation. framework into the Frameworks folder. After that just drag and paste the music or audio file into the resources folder, which you are going to play on button click.

Once you done, just open your ViewController.xib file and add three buttons for the different actions and hooked them with the appropriate actions. Now just look into the code ... your code must look like the given one.

buttonSoundViewController.h

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

@interface buttonSoundViewController : UIViewController <AVAudioPlayerDelegate> {

    AVAudioPlayer *theAudio;

}

-(IBAction) playSound:(id)sender;
-(IBAction) stop:(id)sender;
-(IBAction) pause:(id)sender;

@end

buttonSoundViewController.h

#import "buttonSoundViewController.h"

@implementation buttonSoundViewController

-(IBAction) playSound:(id)sender{

    [theAudio play];

}

-(IBAction) stop:(id)sender{
[theAudio stop];
}

-(IBAction) pause:(id)sender{
[theAudio pause];
}

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {

NSString *path = [[NSBundle mainBundle] pathForResource:@"awh_man" ofType:@"wav"];

theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];

theAudio.delegate=self;

theAudio.numberOfLoops = -1;

[super viewDidLoad];
}

- (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 {
[super dealloc];
}

@end

Unlike the previous example of "sound on button click", we have created the NSBundle class but instead of defining it into the button action, we witted it into the "ViewDidLoad" event. And on the button actions we have just given the variable names with appropriate actions like play, pause and stop. Take a look at the code...

ViewDidLoad event

- (void)viewDidLoad {

NSString *path = [[NSBundle mainBundle] pathForResource:@"awh_man" ofType:@"wav"];
theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate=self;
theAudio.numberOfLoops = -1;

[super viewDidLoad];
}

Button Actions

-(IBAction) playSound:(id)sender{

    [theAudio play];

    }
-(IBAction) stop:(id)sender{
    [theAudio stop];
}
