Question

How do I gain access to a crashSound.wav file I’ve put in my Supporting Files folder of my xCode Project? Because the following code isn’t working :

@interface Game()
{
    // code...

    AVAudioPlayer *crashSound;

    // code...
}
@end

@implementation Game

- (id) init 
{ 
    // code...

    NSURL *crashSoundFile = [[NSURL alloc] initWithString:@"crashSound" ]; // <--PROBLEM

    crashSound = [[AVAudioPlayer alloc] initWithContentsOfURL:crashSoundFile error:NULL];

    // code...
}
-(void) play // this is my "main" method that will be called once the playButton is pressed
{
   [crashSound play];[crashSound play];[crashSound play];

}
@end

@"crashSound" is not a valid URL. You must supply an actual URL.

URLs to images, sounds, etc. (resources) in your project are not predictable at compile-time, and must be generated at run-time. This is easy using NSBundle.

NSBundle *bundle = [NSBundle mainBundle];
NSURL *crashSoundFile = [bundle URLForResource: @"crashSound" withExtension: @"wav"];

Ta da.
