NSDictionary到CGPoint

Question

我正在开发一款游戏,其中我试图点击两种不同的类型,如果分别点击单击和双击.

继承人我在触摸开始的方法:

- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
    for( UITouch *touch in touches ) 
    {

        CGPoint location = [touch locationInView: [touch view]];
        location = [[CCDirector sharedDirector] convertToGL: location];

        NSLog(@"TOUCH LOCATION IN TOUCH BEGAN  = (%f , %f)", location.x , location.y);

        NSUInteger tapCount = [touch tapCount];

        switch (tapCount)
        {
            case 1:
            {
                NSDictionary * touchloc = [NSDictionary dictionaryWithObject:[NSValue valueWithCGPoint:location] forKey:@"location"];
                [self performSelector:@selector(startTimer:) withObject:touchloc afterDelay:3];
                break;
            }   
            case 2:
            {
                [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(startTimer) object:nil];
                [self performSelector:@selector(removeBall) withObject:nil afterDelay:1];
                break;
            }

            default:
            {
                break;
            }
        }
  }

现在,perform selector(startTimer:)在我接触到的点的坐标NSPoint(我正在使用NSDictionary)所有我想知道的是......我们如何将这些点转换为CGPoints ...？

不知道怎么办呢？

任何帮助将得到真正的赞赏.

如果你正在使用,NSValue你可以CGPoint从那里使用CGPointValue.

例如

NSDictionary * touchloc = [NSDictionary dictionaryWithObject:[NSValue valueWithCGPoint:location] forKey:@"location"];
    CGPoint points = [[touchloc valueForKey:@"location"] CGPointValue];
