位置不同CGPoint

Question

你好 我如何找到这两个cgpoint？他只给了我一个。

-(void)gestureLoad {

//GESTURE

UIGestureRecognizer *recognizer;


recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(numTap2:)];
[(UITapGestureRecognizer *)recognizer setNumberOfTouchesRequired:2];
[self.view addGestureRecognizer:recognizer];
self.tapRecognizer = (UITapGestureRecognizer *)recognizer;
recognizer.delegate = self;
[recognizer release];
}

- (void)numTap2:(UITapGestureRecognizer *)recognizer {


CGPoint location = [recognizer locationInView:self.view];


...other actions...
}

多谢！

Answer 1

从-[UIGestureRecognizer numberOfTouches]的描述来看：

使用此返回值
循环中的方法，您可以要求
使用单个触摸的位置
locationOfTouch:inView: 方法。

因此，为每次触摸调用 -locationOfTouche:inView: 来获取相应的位置。
