Sound overlapping with multiple button presses

Question

When I press a button, then press another one, the sounds overlap. How can I fix that so the first sound stops when another one is pressed?

 - (void)playOnce         


        

Answer 1

Add a check to see if the player is already playing at the beginning of each method:

if (theAudio.playing == YES) {
    [theAudio stop];
}
