在这一章中学习到多分辨率屏幕适配问题,ScrollView、assets.xcassets 的初步认识

        // Do any additional setup after loading the view, typically from a nib.
        
        let iosDeviceScreenSize: CGSize = UIScreen.main.bounds.size//初始化关于设备的结构体
        
        let deviceWidth = iosDeviceScreenSize.width//设备的宽,单位(点)pt
        let deviceHeight = iosDeviceScreenSize.height//设备的高,单位(点)pt
        let deviceName = UIDevice.current.name  //获取设备名称 例如:梓辰的手机
        let sysName = UIDevice.current.systemName //获取系统名称 例如:iPhone OS
        let sysVersion = UIDevice.current.systemVersion //获取系统版本 例如:9.2
        let deviceUUID = UIDevice.current.identifierForVendor?.uuidString//获取设备唯一标识符 例如:FBF2306E-A0D8-4F4B-BDED-9333B627D3E6
        let deviceModel = UIDevice.current.model //获取设备的型号 例如:iPhone
        
        print("\(deviceName) - \(sysName) - \(sysVersion) - \(deviceModel) - \(deviceUUID) - ")
        print("\(deviceWidth) - \(deviceHeight)")

        }
        
    }
    
    override func viewDidLayoutSubviews() {
        self.ScrollView.contentSize = CGSize.init(width: self.view.frame.size.width, height: 1000)
        //设置scrollView的CG(滚动的)宽和高
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
