iOS 全局竖屏单个viewcontroller点击按钮支持横屏

问题描述：项目工程只支持竖屏，在播放器页面需要点击按钮进行横竖屏切换，并能根据手机的方向进行自动旋转

如图：只勾选了竖屏

解决方法：（主要是采用视图transform的原理横屏时调整视频视图上的每个控件坐标位置竖屏在调整回去）

1.电池状态栏的显示与隐藏

首先在plist文件中添加View controller-based status bar appearance 设置为no

然后在控制器中通过[[UIApplication sharedApplication] setStatusBarHidden: withAnimation:NO]方法

[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];

来显示或者隐藏状态栏，一般情况下竖屏时状态栏会显示横屏则隐藏

导航栏也进行隐藏换成自己的头部视图条

self.navigationController.navigationBarHidden = YES;

2.通知监测状态栏方向（自动旋转屏幕）

设置全局的orientation：

orientation = [UIDevice currentDevice].orientation;

通知：

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientChange:) name:UIDeviceOrientationDidChangeNotification object:nil];

方法：

- (void)orientChange:(NSNotification *)noti {
//    UIDeviceOrientation orientation = [UIDevice currentDevice].orientation;

    orientation = [UIDevice currentDevice].orientation;

    NSLog(@"打印现在的设备方向：%ld",(long)orientation);
    switch (orientation)
    {
        case UIDeviceOrientationPortrait: {
            NSLog(@"屏幕竖直");
            isFullScreen = NO;
            [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];
//            [UIView animateWithDuration:0.25 animations:^{
//                playView.transform = CGAffineTransformMakeRotation(0);
//                playView.frame = CGRectMake(0, 0, widthAll, 300);
//                topView.frame = CGRectMake(0, 0, widthAll, 50);
//                footView.frame = CGRectMake(0, 250, widthAll, 50);
//                menuBtn.frame = CGRectMake(widthAll-100, 10, 100, 30);
//            }];
            [self shupinAction];
        }
             break;

        case UIDeviceOrientationLandscapeLeft: {
            
            isFullScreen = YES;
            NSLog(@"屏幕向左转");
            [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
            [self rightHengpinAction];
//            [UIView animateWithDuration:0.25 animations:^{
//                playView.transform = CGAffineTransformMakeRotation(M_PI*0.5);
//                playView.frame = CGRectMake(0, 0, widthAll, heightAll);
//                topView.frame = CGRectMake(0, 0, heightAll, 50);
//                footView.frame = CGRectMake(0, widthAll-50, heightAll, 50);
//                menuBtn.frame = CGRectMake(heightAll-100, 10, 100, 30);
//            }];
        }
            break;
        case UIDeviceOrientationLandscapeRight: {
            isFullScreen = YES;
            NSLog(@"屏幕向右转");
            [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
            [self leftHengpinAction];
//            [UIView animateWithDuration:0.25 animations:^{
//                playView.transform = CGAffineTransformMakeRotation(-M_PI*0.5);
//                playView.frame = CGRectMake(0, 0, widthAll, heightAll);
//                topView.frame = CGRectMake(0, 0, heightAll, 50);
//                footView.frame = CGRectMake(0, widthAll-50, heightAll, 50);
//                menuBtn.frame = CGRectMake(heightAll-100, 10, 100, 30);
//            }];
        }
            break;
        default:
            break;
    }
}

3.点击按钮进行横竖屏切换

添加按钮，设置点击方法

-(void)rotateScreeen:(UIButton *)btn
{
    NSLog(@"旋转屏幕");
    btn.selected = !btn.selected;
    if (btn.selected) {
        isFullScreen = YES;
        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:NO];
        
        if (orientation == UIDeviceOrientationPortrait) {
            NSLog(@"当前竖屏模式");
            [self rightHengpinAction];
        }else if(orientation == UIDeviceOrientationLandscapeLeft)
        {
            NSLog(@"当前左横屏模式");
            [self shupinAction];
        }else if(orientation == UIDeviceOrientationLandscapeRight)
        {
            NSLog(@"当前右横屏模式");
            [self shupinAction];
        }
        
        
    }else{
        isFullScreen = NO;
       [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];
        [self shupinAction];

    }
    

}
