Closed 4 years ago.
I can't figure out how to play a music file in an iPhone game.
Im creating a Game and I am trying to figure out how to play music whenever the app is launched.
I tried this:
- (void)awakeFromNib {
NSString *path = [[NSBundle mainBundle] pathForResource:#"musicamenu" ofType:#"mp3"];
AVAudioPlayer *theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
[theAudio play];
}

This is how you do it. In your v1AppDelegate.h file add
#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>
#interface v1AppDelegate : UIResponder <UIApplicationDelegate>
{
AVAudioPlayer *myAudioPlayer;
}
#property (nonatomic, retain) AVAudioPlayer *myAudioPlayer;
#property (strong, nonatomic) UIWindow *window;
#end
Now in your v1AppDelegate.m file add this
#import "v1AppDelegate.h"
#import <AVFoundation/AVFoundation.h>
#import <AudioToolbox/AudioToolbox.h>
#implementation v1AppDelegate
#synthesize window = _window;
#synthesize myAudioPlayer;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//start a background sound
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"Soothing_Music2_Long" ofType: #"mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath ];
myAudioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];
myAudioPlayer.numberOfLoops = -1; //infinite loop
[myAudioPlayer play];
// Override point for customization after application launch.
return YES;
}
If you wish to stop or start this music from anywhere else in your code then simply add this
#import "v1AppDelegate.h"
- (IBAction)stopMusic
{
v1AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
[appDelegate.myAudioPlayer stop];
}
- (IBAction)startMusic
{
v1AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
[appDelegate.myAudioPlayer play];
}

I recommend to add the play music method in applicationDidBecomeActive: method. Because you want the music played every time the app is launched. Note you should hold a reference to the player. Else the music will not be played.
- (void)applicationDidBecomeActive:(UIApplication *)application
{
// Play music on another queue so that the main queue is not blocked.
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[self playMusic];
});
}
- (void)playMusic
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"done" ofType:#"mp3"];
NSError *error = nil;
NSURL *url = [NSURL fileURLWithPath:path];
self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[self.player play];
}

For Swift 3.1 :
Use this two imports :
import AVFoundation
import AudioToolbox
Create a reference for your AVAudioPlayer :
private var mAudioPlayer : AVAudioPlayer?
Use this function for play a sound you are storing in your app :
func onTapSound(){
let soundFile = Bundle.main.path(forResource: "slap_placeholder.wav", ofType: nil)
let url = URL(fileURLWithPath: soundFile!)
self.mAudioPlayer = try! AVAudioPlayer(contentsOf: url as URL)
self.mAudioPlayer?.play()
}
