Sprite Kit declaration a local node

Question

Which way is recommended for declare a local node?

(1) inside interface in the header file

@interface MyScene() <SKPhysicsContactDelegate>

@property (nonatomic) SKSpriteNode *player;            

@end

(2) inside interface in the implementation file

@interface MyScene() 

@property (nonatomic) SKSpriteNode *player;            

@end

(3) inside implementation in the implementation file

@implementation MyScene
{
    SKSpriteNode *_player;
}
