-(void)dealloc
{
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIApplicationUserDidTakeScreenshotNotification object:nil];

//监测当前设备是否处于录屏状态
    UIScreen * sc = [UIScreen mainScreen];

        if (sc.isCaptured) {
            NSLog(@"正在录制~~~~~~~~~%d",sc.isCaptured);
            [self screenshots];
        }
    } else {
        // Fallback on earlier versions
    }
    if (@available(iOS 11.0, *)) {

        [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(screenshots) name:UIScreenCapturedDidChangeNotification  object:nil];
