I don't know if this is objective C / Cocos2D specific, and if it is objective C, maybe someone could tell me the ideal forum to ask that question?

This is just a function to test if a board is clear, and I'm creating a pointer and setting it to whichever cell we're checking. The object in the boardArray is a Block which subclasses CCSprite.

Heres the code:

-(bool)boardCleared {
for (int i = 0; i < 8; i++) {
for (int j = 0; j<8; j++) {
Block * blocko = [[boardArray objectAtIndex:i] objectAtIndex:j];
if (blocko.blockType != 0) {
return NO;
}
}
}
return YES;
}

The question is, is the pointer blocko need to be released? Or does it not count.

Thanks

SwizzerSweet, you do not need to release the pointer blocko. blocko is a local variable that is destroyed when you return from the method -(bool)boardCleared; blocko is not an object itself, it merely points to an object that you already created, or in this case, many objects as you cycle through your two for loops.

The rule of thumb here is - if you did not alloc it or retain it, you do not need to release it.

Okay thanks. :)

I wasn't sure if pointers are considered primitives or not.
