Question

Learning as always, was going along quite nicely, until I realized I had no idea what the differences meant between these.

@class Player;
@class Map;

@interface View : NSView
{
    Player* player_;
    Map* currentMap_;
    NSMutableArray *worldArray;
    NSMutableArray *itemArray;
    float cellHeight_;
}

@end

Never mind, turns out the side the star is on has no effect at all. Now I know why I was so confused.

Answer 1

All objective C objects are referenced by pointers, which is what the * denotes. Whether the star is on the left or the right doesn’t matter to the compiler; I believe it’s personal preference.

float doesn’t have a * because it’s a C primitive, not an Objective C object.
