[iOS 仿QQ消息推送框 - (遮住顶部状态栏)]

老样子看图:

上图是有Bug 的 下面是正确的图

遮罩方法参考:
IOS截图分享，状态栏挡住了UIView处理

这里的self 指UIView(即你用来遮住状态栏的view.)

   //遮盖状态栏方法
        UIWindow *wd = [self mainWindow];
        [wd addSubview:self];
        wd.windowLevel = UIWindowLevelAlert;

/** 获取window */
- (UIWindow*)mainWindow{

    UIApplication *app = [UIApplication sharedApplication];
    if ([app.delegate respondsToSelector:@selector(window)])
    {
        return [app.delegate window];
    }
    else
    {
        return [app keyWindow];
    }
}

用到的方法:
添加轻扫手势

     //添加向上的轻扫手势
        UISwipeGestureRecognizer *swipGR = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipaction:)];
        swipGR.direction = UISwipeGestureRecognizerDirectionUp;//设置扫的方向
        [self addGestureRecognizer:swipGR];

/** 轻扫手势(向上) */
- (void)swipaction:(UISwipeGestureRecognizer*)sender{
    if (sender.state == UIGestureRecognizerStateEnded) {
        [self animationUP:0.15f delay:0.f];
    }

}

具体Demo代码贴出

1.调用方法

     SDDrowNoticeView   *v = [SDDrowNoticeView createDrowNoticeView:@[@"消息标题",@"消息内容-消息内容"]];
        [self.view addSubview:v];
        [v animationDrown];

以上

(也可以添加播放系统提示音的功能, 这个稍后加上吧)
