  1. 2011.08.17 [IPhone Dev] CGPoint NSMutableArray (2)
  2. 2011.08.10 [CGPoint Array] CGPoint MutableArray?

You can't use NSMutableArray with CGPoint.

In other language we can just use " List<Template> ".

But in objective-c we use like this.

NSMutableArray * pointArray = [NSMutableArray array];

[pointArray addObject:[NSValue valueWithCGPoint:location]];

[pointArray addObject:[NSValue valueWithCGPoint:lastPoint]];


CGPoint retrievedPoint = [[pointArray objectAtIndex:0CGPointValue];

Turns out, we can only use NSMutableArray with a class or something that can make a instance with it.

So now you got a solution.

Have a good time~

CGPoint로는 MutableArray를 사용할 수가 없네;

왜 List를 만들어 놓지 않은 걸까;;

List<CGPoint> list;

이러면 얼마나 쉽니;;

암턴 해결 방법은 아래와 같다.

NSMutableArray * pointArray = [NSMutableArray array];

[pointArray addObject:[NSValue valueWithCGPoint:location]];

[pointArray addObject:[NSValue valueWithCGPoint:lastPoint]];


CGPoint retrievedPoint = [[pointArray objectAtIndex:0] CGPointValue];
