Accessing a value of a class's variable from another - objective-c

Question

This is probably a silly question but I\'m having a hard time trying to solve it. The thing is that a have a class that implements a counter and at the end of it procedures

Answer 1

In your header file you declare your iVar as

{
    int movesCounter;
}

but you synthesize the property with

@synthesize movesCounter = _movesCounter; // note the underscore

so the movesCounter iVar does not get connected to the movesCounter property. If you are updating just movesCounter instead of self.movesCounter or _movesCounter then external classes will not be able to see these changes.
