iphone - MemoryLeak problem in following case -

i getting memory leak when click play button....

i testing "leak" tool under "run , performance tool"....on simulator

i getting leak when click play button first time.....

here code....

-(ibaction)play {       [self setplayer];     [self playme];   }    -(ibaction)stop {     [self stopme];     [self releaseplayer];  }   -(void)setplayer {      nsurl *file = [[nsurl alloc] initfileurlwithpath:                    [[[nsbundle mainbundle] resourcepath] stringbyappendingpathcomponent:@"shut up.mp3"]];     nserror *err = nil;     player = [[avaudioplayer alloc] initwithcontentsofurl:file error:&err];      [file release];     player.numberofloops = -1;     [player preparetoplay];     player.volume=1.0;   }   -(void)playme {     if (!isplaying)     {         [player play];         isplaying=yes;     } }   -(void)stopme {     if (isplaying)     {         [player stop];         isplaying=no;     } }  -(void)releaseplayer {     if(!isplaying)     {         [player release];         player=nil;     }     isplaying=no; } 

i think, below statement source of memory leak,

player = [[avaudioplayer alloc] initwithcontentsofurl:file error:&err];

as per blog tutorial code must below.

-(void)setplayer {      nsurl *file = [[nsurl alloc] initfileurlwithpath:                    [[[nsbundle mainbundle] resourcepath] stringbyappendingpathcomponent:@"shut up.mp3"]];     nserror *err = nil;      nsdata *data = [nsdata datawithcontentsoffile:file];     avaudioplayer *player = [avaudioplayer alloc];         if([player initwithdata:audiodata error:null])      {          player.numberofloops = -1;         [player preparetoplay];         player.volume=1.0;         [player autorelease];     }      else      {         [player release];         player = nil;     }     [file release]; } 

the leak-free version stores pointer returned alloc, rather pointer returned initwithdata:error:. way, whatever happens, player can still released.
