开机动画 开灯关灯

开灯关灯

 if(sender.selected) {
               
                [sender setTitle:@"关灯"forState:UIControlStateNormal];
                [device setTorchMode:AVCaptureTorchModeOn];
                [device setFlashMode:AVCaptureFlashModeOn];
               
            } else {
               
                [sender setTitle:@"开灯"forState:UIControlStateNormal];
                [device setTorchMode:AVCaptureTorchModeOff];
                [device setFlashMode:AVCaptureFlashModeOff];
               
            }

            [deviceunlockForConfiguration];

开机动画,或者再window上写,不过需要纯代码创建window

staticdispatch_once_tonceToken;

   dispatch_once(&onceToken, ^{
       
       
        // 开机启动动画
        UIImageView*splashView = [[UIImageViewalloc]initWithFrame:CGRectMake(0,0,ScreenWidth,ScreenHeight)];
        //将图片添加到UIImageView对象中
        splashView.image=[UIImageimageNamed:@"bg_night_snow"];
        [self.viewaddSubview:splashView];
        [self.viewbringSubviewToFront:splashView];
        [UIView animateWithDuration:4.fanimations:^{
           
            self.navigationController.navigationBar.hidden= YES;
            splashView.frame=CGRectMake(-55/375. * ScreenWidth, -100./ 667 *ScreenHeight,ScreenWidth + 100,ScreenHeight + 100+100);
        } completion:^(BOOLfinished) {
            splashView.hidden= YES;
            self.navigationController.navigationBar.hidden= NO;

        }];

    });
