iphone - Stopping the audio after playing with AVAudioPlayer -

hi guys hope can me issue.

what when user left view b view a, audio plays, when user left view view b, audio stops.

so when user left view b (removing viewb superview) main view view a, methods playit & hahaplay called. when user left view view b (view add subview b) stopplaying method called instead. here's problem, stopplaying method called, audio not stopped. realised alert shown reason statement> [audioplayer stop]; not functioning.

i've defined audio player in header file fyi.

all methods below in viewcontroller called soundview.

sorry might doing whole thing in wrong way, maybe of can enlighten me , correct mistakes?

-(void)playit{      filepath = [[nsbundle mainbundle] pathforresource:@"6431"                                                 oftype:@"aiff"];     fileurl = [[nsurl alloc] initfileurlwithpath:filepath];     audioplayer = [[avaudioplayer alloc]                     initwithcontentsofurl:fileurl error:nil]; }  -(void)hahaplay{      uialertview *alert = [[uialertview alloc] initwithtitle:@"playing" message:@" playing" delegate:nil cancelbuttontitle:@"yep, did." otherbuttontitles:nil];     [alert show];      [alert release];      [audioplayer preparetoplay];     if(![audioplayer isplaying]){          [audioplayer play];     }  - (void)stopplaying{     uialertview *alert = [[uialertview alloc] initwithtitle:@"stop playing" message:@"stop playing" delegate:nil cancelbuttontitle:@"yep, did." otherbuttontitles:nil];     [alert show];      [alert release];       [audioplayer stop];  } 

maybe you're losing reference somewhere mistake, try setting breakpoint near stop call, , checking audioplayer in case audioplayer nil. saying because reason of these type of problems me...

also following work?

[audioplayer pause] audioplayer.currenttime = 0;
