另一种全屏模式

AppDelegate中做下面几个方法

@property (nonatomic, assign) BOOL screenRotation;
+ (AppDelegate *)getAppdelegate;

/*----------------------------横屏--------------------------------------------*/
+ (AppDelegate *)getAppdelegate{
    return (AppDelegate *)[UIApplication sharedApplication].delegate;
}

- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    if (self.screenRotation){
        return UIInterfaceOrientationMaskLandscapeRight;
    }
    return UIInterfaceOrientationMaskPortrait;
}
/*----------------------------end--------------------------------------------*/

然后强制横屏，这里是直接将手机强制横了过来。。。

- (void)old_fullView{
    [AppDelegate getAppdelegate].screenRotation = true;
    [[UIDevice currentDevice] setValue: [NSNumber numberWithInteger: UIInterfaceOrientationLandscapeRight] forKey:@"orientation"];

    /***新方法***/
    /*记录进入全屏前的parentView和frame*/
    self.videoView.videoViewParentView = self.videoView.superview;
    self.videoView.videoViewFrame = self.videoView.frame;
    
    
    self.videoView.frame = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height);
    
    [kAPP_Window addSubview:self.videoView];
}


- (void)old_backView{
    [AppDelegate getAppdelegate].screenRotation = false;
    [[UIDevice currentDevice] setValue: [NSNumber numberWithInteger: UIInterfaceOrientationPortrait] forKey:@"orientation"];
    
    self.videoView.frame = self.videoView.videoViewFrame;
    [self.videoView.videoViewParentView addSubview:self.videoView];
}
