You can use the singleton design pattern and make a global object. But in general global variables / objects / singletons are a hint that something with your design is wrong.

Create a singleton this way:

+ (CardPainter*) sharedPainter { 
    static CardPainter* sp; 
    static dispatch_once_t token; 
    dispatch_once(&token, ^{  
        sp = [[CardPainter alloc] init]; 
    });
    return sp; }
