Bad access code when allocating a class containing a CGPoint and initializing it

Question

I have been trying to figure out what is the problem with the code I've written and I have not the slightest clue why is it wrong. Another thing I noticed was that Xcode is treating my CGPoint as a pointer, preventing me from using arrow notation. I need it to be a property for the purposes of my program in .h file

@property (nonatomic) CGPoint* directionUsed;

in controller file

// up is just an instance of the class direction.
// Direction is a class that returns itself

self.up =    [[Direction alloc]initWithX:0 y: -1]; 

designated initializer in .m file:

-(id)initWithX:(int)x y:(int)y{

self = [super init];

if(self){
    self.directionUsed->x = x; //not letting me use dot notation
    self.directionUsed->y = y;
}
return self;

}

Thanks for the help!

Answer 1

The problem is that you defined your CGPoint as pointer

just change your code

from

@property (nonatomic) CGPoint* directionUsed;

to

@property (nonatomic) CGPoint directionUsed;

Edit

In order to assign a value to directionUsed you need to allocate the struct first You need to change your code

from

self.directionUsed->x = x;
self.directionUsed->y = y;

to

CGPoint point;
point.x = x;
point.y = y;
self.directionUsed = point;
