   I've got a class that i'm trying to have save an array of information, it's something like

   //my .h file
   @interface mySprite : CCSprite {
   	NSMutableArray *myArr;
   }
   
   -(void)SetArr: mArr:(NSMutableArray *)someArr;
   -(NSMutableArray *)GetArr;
   
   //my .m file
   
   -(void) setArr:(NSMutableArray *)someArr {
   		myArr = arrFileNames;
   		NSLog(@"SetSoundFile: \n%@",myArr);
   }
   
   -(NSMutableArray *)GetArr {
   	return myArr;
   }

   my problem is that when i set myArr, it's taking the values and my NSLog is showing me the contents of myArr. When I go and call GetArr to get the array, it comes back empty.

   HELP!

   You need to retain objects that your class will be managing:

   -(void) setArr:(NSMutableArray *)someArr {
   		[myArr release];
   		myArr = [someArr retain];
   		NSLog(@"SetSoundFile: \n%@",myArr);
   }
   
   -(NSMutableArray *)GetArr {
   	return myArr;
   }
   
   - (void) dealloc
   {
       [myArr release];
       [super dealloc];
   }

   KArl is right, but I want to add that you must check for self assignment in your setter, otherwise it will be referencing garbage when release is called in the settr. Why not use @property and let the compiler write the setters and getters?

   @Shemp: Mostly because i'm still new to obj-c. Thanks to you and @Karl for your help.
