Cocos2d MenuItem Selector and Accessing Instance Variable

Question

I have an instance variable declared in the implementation file which can be accessed using the property defined by synthesize

@synthesize myProperty

Now, I want to assign this property something inside the Selector event of the MenuItem in cocos2d library. You can think of it as a accessing myProperty in a callback function. For some reason whenever I access the property it says "property is out of scope". So I tried to assigned the access the self.myProperty which worked!!

But now I have a memory leak in self.myProperty. If I release self.myProperty in dealloc then it throws an exception saying that I also have myProperty release.

UPDATE 1: (Code)

NSString *voice;

@property (nonatomic,retain) NSString *voice; @synthesize voice;

-(void)repeatAlphabet:(id)sender 

{
 *// I cannot access the voice variable in this function.* 

[[SimpleAudioEngine sharedEngine] playEffect:[[voice lowercaseString] stringByAppendingString:@".caf"]]; 
}

-(void) addRepeatButtonOnScreen 

{

CCMenuItemImage * menuItem1 =[CCMenuItemImage itemFromNormalImage:@"image1.png"

selectedImage: @"image2.png"

  target:self

selector:@selector(repeatAlphabet:)];

CCMenu *menu = [CCMenu menuWithItems:menuItem1,nil]; 

menu.position = ccp(30, 450); 

[self addChild:menu]; 


}

Answer 1

Assuming you have defined an ivar corresponding to your property also called myProperty, and that your property is either retain or copy: in your dealloc you should do [myProperty release]; not [self.myProperty release].

UPDATE: after discussion and more code shown... 'out of scope' can be a symptom of not having retained a value that should be retained. For instance for a string value = @"Value" doesn't retain (and will become out of scope), fixed by using self.value = @"Value" or value = [@"Value" retain].
