objective-c - how can I use a CGPoint value from one method in another within the same class

Question

Sorry if this sounds quite simple. I am new to Cocos2d and Obj-C. I want to compare the CGPoint value of a sprite in one method with a value caluculated in another method. How can I access this value from one method to another within the same class?

Answer 1

メソッドに渡すか、値を保持するプライベート プロパティを宣言します。

@property (nonatomic, assign) CGPoint myCGPoint;

そして、実装ファイルで合成します。

@synthesize myCGPoint;
