ios触屏事件指南

//在一个函数里面（初始化等）里面添加要识别触摸事件的范围
    infoView=[[UIView alloc] initWithFrame:CGRectMake(20, 100,220, 280)];//范围，出了这个范围就检测不到触摸了
    infoView.backgroundColor=[UIColor blueColor];
    infoView.alpha=0.6;
    [self.view addSubview:infoView];
    /******************监视手势控制*****************///有上下左右，我只用到了左右，上下注掉了。
