ios7 - Why does iOS AVAudioPlayer's prepareToPlay method return false? -


i have array of audio players plays 1 of when user hits location. however, when call [preparetoplay] on player object, returns false - behaviour seems erratic , unpredictable , i'd know reasons return false.

my code looks like:

i = // loop var avaudioplayer *player = [[[myaudio getsharedaudio] audioplayers] objectatindex:i]; if (player != nil && ![[myaudio getsharedaudio] isplaying]) {    if ([player preparetoplay]) {        [player play];    } else {         nslog(@"not prepared.");    } }
