Question

i want to create custom object to get set value on it.

-(id)initWithURLString:(NSString *)url
{
if (self = [super init])
{
    self.XXX = XXX;
    self.YYY = YYY:
}
return self;
}

until here i am ok, i can set / get when i call my custom class. however i need more detailed one. i want to add sub keys to my object variables as like.

myObj.XXX.x

myObj.YYY.y

also i want to set / get sub keys.
any idea much appreciated.
thank you.

Answer 1

In that case, you need the type of XXX to have its own properties.

For instance,

An example subtype interface:

@interface MySubtype : NSObject
  int x;
  int y;
}

@property(nonatomic, assign) int x;
@property(nonatomic, assign) int y;

And an example interface for your main type:

@interface MyType : NSObject
  MySubtype *subType;
}

@property(nonatomic, retain) subType;
