问题描述

UITapGestureRecognizer添加新view

获取触摸的代码：

 UITapGestureRecognizer*singleTap = [[[UITapGestureRecognizer alloc] initWithTarget: self action:@selector(doSingleTap:)] autorelease]; singleTap.numberOfTouchesRequired = 2; [self.view addGestureRecognizer:singleTap

在doSingleTap:方法中：

-(void)doSingleTap:(UITapGestureRecognizer *)recognizer{    CGPoint point = [recognizer locationOfTouch:0 inView:self.view];    NSLog(@""location X =>%flocation  =>%f ""point.xpoint.y);    CGPoint point1 = [recognizer locationOfTouch:1 inView:self.view];    NSLog(@""location X =>%flocation  =>%f ""point1.xpoint1.y);     NSLog(@""location X =>%flocation  =>%f ""xy);    UIView *test1 = [[UIView alloc]initWithFrame:CGRectMake(point.x point1.y x y)];    test1.backgroundColor= [UIColor greenColor];    [self.view addSubview:test1];}

需要的功能就是，通过手指触摸指定位置的屏幕，来添加新的视图，还可以让用户用手指划动调整新视图的坐标，(xywh)。
搜索了很多网页也没找到实现方法，请高手帮忙指点，谢谢。

解决方案

使用TouchBegin 和 TouchMove 来实现比较好.
