I need to create an audio player with 4-5 melodies - iphone

Question

I am new in Iphone SDK programming
I need to create audio player but without array. Melodies have names "sound1, sound2, sound3..."
My code here:
NSUInteger x;
for (x=1; x<=tuneNums; x++)
{
path = [[NSBundle mainBundle] pathForResource:#"sound%d" ofType:#"wav"];
if([[NSFileManager defaultManager] fileExistsAtPath:path])
{
aSound = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:&error];
[aSound setNumberOfLoops:0];
aSound.delegate = self;
[aSound prepareToPlay];
}
}
All button I have and work great, but only with one mellody:( But how release 4-5 melodies i dont know :(
P.S. Forgive me for my english I'm just out of Siberia

Answer 1

You are allocating an AVAudioPlayer on each cycle, and you get only one 'melody' because that's the one allocated in the last cycle.
As 7KV7 pointed out, you should allocate one AVAudioPlayer when the user presses a button, play the corresponding audio file, and then release/recreate it when another button is pressed.
Something like:
- (void)button1Pressed:(id)sender {
// release the current player
if(aSound) {
[aSound release], aSound = nil;
}
// create a new player with the first file
aSound = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:&error];
[aSound setNumberOfLoops:0];
aSound.delegate = self;
[aSound prepareToPlay];
}
How to determine which audio file to play when a button is pressed is up to you. If you are going to have only four audio files, the simplest way is to have a fixed number of buttonPressed selectors (e.g. button1Pressed, button2Pressed) and associate them to your four buttons.

Answer 2

if i got you right you should add the method-
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag{
[player release];
}
and don't forget to set your view controller as the player delegate.
aSound.delegate=self;
