avaudioplayer - How to have multiple audio streams play overlapping in iOS? -

i defining 3 area of screen 'hot-spots' if there touch detected, plays zone-specific sound. works great, except if click on zone 1 , zone 2, zone 2 sounds cuts off zone 1. want sound of zone play until completed. so, if click zone 1 , zone 2, zone 1's sound keep playing, , zone 2 play on zone 1.

here code have (which works fine, doesn't allow audio overlaps):

   if(point.y < 316 && point.y > 76 && point.x < 220 && point.x > 200)     {         nsurl *url = [nsurl fileurlwithpath:[nsstring stringwithformat:@"%@/sound1.mp3", [[nsbundle mainbundle] resourcepath]]];          nserror *error;         audioplayer = [[avaudioplayer alloc] initwithcontentsofurl:url error:&error];         audioplayer.numberofloops = 0;          if (audioplayer == nil)             nslog([error description]);         else             [audioplayer play];     }     if(point.y < 316 && point.y > 76 && point.x < 260 && point.x > 240)     {         nsurl *url = [nsurl fileurlwithpath:[nsstring stringwithformat:@"%@/sound2.mp3", [[nsbundle mainbundle] resourcepath]]];          nserror *error;         audioplayer = [[avaudioplayer alloc] initwithcontentsofurl:url error:&error];         audioplayer.numberofloops = 0;          if (audioplayer == nil)             nslog([error description]);         else             [audioplayer play];     }     if(point.y < 316 && point.y > 76 && point.x < 300 && point.x > 280)     {         nsurl *url = [nsurl fileurlwithpath:[nsstring stringwithformat:@"%@/sound3.mp3", [[nsbundle mainbundle] resourcepath]]];          nserror *error;         audioplayer = [[avaudioplayer alloc] initwithcontentsofurl:url error:&error];         audioplayer.numberofloops = 0;          if (audioplayer == nil)             nslog([error description]);         else             [audioplayer play];     } 

can please me figure out how make these sounds overlap? thanks!

it looks you're reassigning audioplayer each case. if audioplayer playing 1 sound , reassign play other sound, original audioplayer destroyed , stop playing.

the way i've solved problem in past set multiple avplayer objects, like:

avplayer *_player[max_channels]; nsuinteger _currentchannel; 

then play:

_player[_currentchannel] = [[avaudioplayer alloc] initwithcontentsofurl:url error:&error]; _currentchannel++; if (_currentchannel == max_channels) {     _currentchannel = 0; } 

then don't infinite number of overlapping sound effects, can predefine "reasonable" number max_channels , have many overlapping effects before next sound stops first sound.
