How do I make a button play sounds in a certain order using an array?

Question

I'm coding in Objective-C for the iPhone and I am trying create an array that plays a series of sounds. For example the first time I press the button I want it play sound "0.wav", but the second time I want it to play "1.wav", then "2.wav", "3.wav", etc. Then when I've played a total of 14 sounds (up to "13.wav") I want the loop to start over playing with 0.wav. I've looked around Google and the Apple development documentation for almost 4 days without much luck. So if someone could help me generate a code for this that would be greatly appreciated and if you wouldn't mind could you attempt to explain the code briefly so that I can learn what each part does.

Thank you, Joey

EDIT

Okay I've gotten the Array part down (thanks to Thomas) however neither of us are sure how to implement the soundID from the array to the action where I play the sound and how to play that sound. I used the format Thomas used for his array below if that helps you with your answer.

Thanks, Joey

Answer 1

First, create the array of your different sounds and a variable to hold the current index:

NSArray *sounds = [[NSArray alloc] initWithObjects:@"0.wav", @"1.wav", nil]; // add all your files here
NSUInteger currentSound = 0;

Then, when you handle your button tapped event, go to the next sound, and play it. If it's at the end of your NSArray, go back to index 0:

currentSound++;
if (currentSound >= [sounds count]) {
    currentSound = 0;
}

// play the sound. Just call your own method here
[self playSoundWithFilename:[sounds objectAtIndex:currentSound]];
