获取屏幕window

[UIApplication sharedApplication].keyWindow]

屏幕上手势监听

问题：设计弹出层使用window来实现，对item的背景设置了tap事件，并设置了跳转，对window的touch事件进行设置，点击后window消失，但是touch会拦截tap的事件，只好进行修改，对tap设置了代理来进行区别tap动作

代码：

- (void)dismiss{
    [self setHidden:YES];
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    // 点击消失
    [self dismiss];
}
//如果不加手势监听会直接执行touchesBegan  是对话框消失
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {

    // Disallow recognition of tap gestures in the segmented control.
    if ((touch.view ==_bg_head) && (gestureRecognizer == _headtap)) {
        [self gotoEditUserInfoController];
    }
    if ((touch.view ==_bg_setting) && (gestureRecognizer == _settingtap)) {
        [self gotoSettingController];
    }
    return YES;
}
