这是什么平台？ios吗？ios的话，被点击view重写touchesBegan:withEvent:- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event    if (touches.count == 1)//单指操作     {        UITouch *touch = touches.anyObject;        CGPoint touchLocation = [touch locationInView:self.window];        NSLog(@"%@",NSStringFromCGPoint(touchLocation));     }
