ios - Looping .wav file -

i making alarm app iphones , want continuously loop audio until button pressed again. of play audio once when pressed. here's code:

-(ibaction)playaudiobutton:(id)sender {  audioservicesplaysystemsound(playsoundid);  }  - (void)viewdidload {  nsurl *soundurl = [nsurl fileurlwithpath:[[nsbundle mainbundle] pathforresource:@"sound" oftype:@"wav"]];  audioservicescreatesystemsoundid((__bridge cfurlref)soundurl, &playsoundid);  [super viewdidload]; // additional setup after loading view, typically nib. } 

any suggestions?

use avaudioplayer play sound. must add avfoundation.framework project work. start declaring avaudioplayer object. must declared either property strong attribute, e.g.

@property (strong, nonatomic) avaudioplayer *audioplayer; 

or instance variable __strong attribute

@interface class : superclass //or @implementation class {     avaudioplayer __strong *audioplayer; } 

then, load , play file,

- (void)viewdidload {     nsstring *audiofilepath = [[nsbundle mainbundle] pathforresource:@"sound" oftype:@"wav"];     nsurl *audiofileurl = [nsurl fileurlwithstring:audiofilepath];     audioplayer = [[avaudioplayer alloc] initwithcontentsofurl:audiofileurl error:nil];     audioplayer.numberofloops = -1; //plays indefinitely     [audioplayer preparetoplay]; }   - (ibaction)playaudiobutton:(id)sender {     if ([audioplayer isplaying])         [audioplayer pause]; //or "[audioplayer stop];", depending on want     else         [audioplayer play]; } 

and, when want stop playing sound, call

[audioplayer stop];
