Player for iPhone Programming?

I am using AVAudioPlayer in my program, but having touble in something

I have 10 sounds, and as I click one to play or th开发者_运维技巧en others don't stop, I tried to solve by

[myPlayer stop];
myPlayer = nil;

it works, but takes time, so what should I do to stop when it click 2nd row on tableview for playing another sound?

If any query regarding question, you may ask in comments,
