swift 播放器全屏显示

点击全屏按钮

    @objc func clickFullScreenButton() {
        isFullScreen.toggle()
        DispatchQueue.main.async {
            UIDevice.current.setValue(self.isFullScreen ? UIInterfaceOrientation.landscapeRight.rawValue : UIInterfaceOrientation.portrait.rawValue, forKey: "orientation")
        }
    }

 

    public var isFullScreen: Bool = false {//是否全屏
        didSet {
            DispatchQueue.main.async {
                if self.isFullScreen {
　　　　　　　　　　　　//videoView 重新布局
                    self.videoView.snp.remakeConstraints { (remake) in
                        remake.left.right.equalTo(0)
                        remake.top.equalTo(0)
                        remake.height.equalTo(ScreenWidth)
                    }
                    self.navigationController?.setNavigationBarHidden(true, animated: true)
                    
                } else {
                    self.videoView.snp.remakeConstraints { (remake) in
                        remake.left.right.top.equalTo(0)
                        remake.height.equalTo(180)
                    }
                    self.navigationController?.setNavigationBarHidden(false, animated: true)
                    
                }
                
                self.view.bringSubviewToFront(self.videoView)
            }
        }
    }

 

给 ViewController 添加系统旋转通知

    NotificationCenter.default.addObserver(self, selector: #selector(orientationDidChange), name:UIDevice.orientationDidChangeNotification, object: nil)
    sharedDelegate.rotate = true

    @objc func orientationDidChange() {
        if playerItem == nil {
            return
        }
        let ttt = UIDevice.current.orientation
        if ttt == .landscapeLeft || ttt == .landscapeRight {
            isFullScreen = true
        }
        if ttt == .portrait {
            isFullScreen = false
        }
    }

 

 

AppDelegate 中 添加变量和方法

    var rotate = false
    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        if rotate {
            return .allButUpsideDown
        }
        return .portrait
    }

 

退出时

    override func viewWillDisappear(_ animated: Bool) {
        sharedDelegate.rotate = false
        UIDevice.current.setValue(UIInterfaceOrientation.portrait.rawValue, forKey: "orientation")
    }
