1. UIView 視圖的漸層填充

override func viewDidLoad() {

        super.viewDidLoad()

        // Do any additional setup after loading the view, typically from a nib.

        //漸層填充色的圖形

        let rect = CGRect(x: 30, y: 60, width: 200, height: 200)

        let gradientView = UIView(frame: rect)

        let gradientLayer = CAGradientLayer()

        gradientLayer.frame = gradientView.frame

        

        let fromColor = UIColor.yellowColor().CGColor

        let midColor = UIColor.redColor().CGColor

        let toColor = UIColor.purpleColor().CGColor

        gradientLayer.colors = [fromColor,midColor,toColor]

        //將設定好的漸層層,添加到視圖對象的層中.

        view.layer.addSublayer(gradientLayer)

        //將視圖對象,添加到當前視圖控制器的根視圖

        self.view.addSubview(gradientView)

    }

 

2. UIView視圖的紋理

override func viewDidLoad() {

        super.viewDidLoad()

        // Do any additional setup after loading the view, typically from a nib.

        

        

        //將匯入的圖片作為紋理,平鋪整個螢幕

        let image = UIImage(named: "Sample")

        //建立顏色對象,將匯入的圖片賦予該對象

        let patternColor = UIColor.init(patternImage: image!)

        self.view.backgroundColor = patternColor

    }
