iphone - release sounds and memory manegment -

hello in application use code below handle , play sounds, want know if need release things or nothing do.

the code :

 -(void) playnote: (nsstring*) note type: (nsstring*) type {  cfurlref        soundfileurlref; systemsoundid   soundfileobject; cfbundleref mainbundle; mainbundle = cfbundlegetmainbundle ();     // url sound file play     soundfileurlref  =  cfbundlecopyresourceurl (mainbundle,             (cfstringref)note,             (cfstringref)type,             null);      // create system sound object representing sound file     audioservicescreatesystemsoundid (soundfileurlref, &soundfileobject);      audioservicesplaysystemsound (soundfileobject); } 

thanks ,

you need call

audioservicesdisposesystemsoundid 

to clean when done sound.

in header

@interface xyz {   systemsoundid soundfileobject; }; 

in .m file, create init method (if dont have one):

-(id)init {    if ( (self = [super init]) )    {      audioservicescreatesystemsoundid (soundfileurlref, &soundfileobject);    }    return self; } 

in dealloc

-(void)dealloc {    audioservicedisposesystemsoundid(soundfileobject);    [super dealloc]; } 

you should declare soundfileurlref ivar
