iOS实现视频播放全屏和取消全屏功能

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

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

///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];   } }

- (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]; } }
