iOS 视频播放全屏和取消全屏功能实现

iOS 视频播放全屏和取消全屏功能实现 所需全屏的视频所在的vc需要导航控制器控制

自定义 全屏vc VedioPlayerViewController 并定义属性

/// 自定义的那个视频类
///@property (nonatomic,strong) VedioPlayer *vedioPlayer;

在VedioPlayer中定义属性

///视频展示的view 的父视图
@property (nonatomic,strong) UIView *currentSuperView;

在视频类定义方法 全屏实现

///取消全屏
- (void)fullScreen:(UIBarButtonItem *)btnItem{
	///视频展示的view 的父视图
    self.currentSuperView = self.superview;
    ///拿到window
    UIWindow *window = [UIApplication sharedApplication].keyWindow;
    ///全屏vc初始化
    VedioPlayerViewController *vc = [VedioPlayerViewController new];
 	///判断是否由导航控制器控制
    if ([window.rootViewController isKindOfClass:[UINavigationController class]]) {
    	///拿到导航控制器控制
        UINavigationController *nvc = (UINavigationController *)window.rootViewController;
        ///把全屏视频的vc推进去
        [nvc pushViewController:vc animated:NO];
        ///重新设置视频大小
        [self setFrame:CGRectMake(0, 0, vc.view.frame.size.width, vc.view.frame.size.height)];
        
        //全屏后 按钮绑定取消全屏方法
        [self.fullScreenItem setAction:@selector(cancelFullScreen:)];
         
        ///vc.conciseVedioPlayer = self;
        ///添加视频到全屏vc
        [vc.view addSubview:self];
		
		///自动播放
		[vc.conciseVedioPlayer startOrStop];
        
    }
    
}

在视频类定义方法 取消全屏实现

- (void)cancelFullScreen:(UIBarButtonItem *)btnItem{
    
    ///拿到window
    UIWindow *window = [UIApplication sharedApplication].keyWindow;
 	///判断是否由导航控制器控制
    if ([window.rootViewController isKindOfClass:[UINavigationController class]]) {
    	///拿到导航控制器控制
        UINavigationController *nvc = (UINavigationController *)window.rootViewController;
        ///推出一个vc，自然就回到原来的视图了
        [nvc popViewControllerAnimated:NO];
        ///把视频添加到原本的视图
        [self.currentSuperView addSubview:self];
        ///重新设置视频大小
        [self setFrame:self.currentFrame];
       
       	//取消全屏后 按钮重新绑定全屏方法
        [self.fullScreenItem setAction:@selector(fullScreen:)];
         ///自动播放
        [self startOrStop];
    }
    
}
