TVButton

TVButton 可在 UIButton 控件上重新创建类似于在 Apple TV 上看到的美丽视差效果。长按或拖动即可触发效果。要使用视差效果，您至少需要两/三层具有相同尺寸的图像。以下是一个具体实例：

let bg = TVButtonLayer(image: UIImage(named: "TVBG.png")!)
let pattern = TVButtonLayer(image: UIImage(named: "TVBtnPattern.png")!)
let top = TVButtonLayer(image: UIImage(named: "TVbtnTop.png")!)
tvButton.layers = [background, pattern, top]

然后，您可以通过更改以下属性来自定义视差效果强度：

tvButton.parallaxIntensity = 1.3

TKRubberIndicator

TKRubberIndicator是Swift制作的库，它可在应用程序中添加橡胶动画页面控件。要使用它，您需要首先导入TKRubberPageControl框架。然后，您需要将以下代码添加到控制器中：

override func viewDidLoad() {
        super.viewDidLoad()

        page.center = self.view.center
        page.valueChange = {(num) -> Void in
            print("Closure : Page is \(num)")
        }
        page.addTarget(self, action: "targetActionValueChange:", forControlEvents: UIControlEvents.ValueChanged)
        self.view.addSubview(page)

        page.numberOfpage = 2
    }

    @IBAction func pageCountChange(sender: UISegmentedControl) {
        page.numberOfpage = (sender.selectedSegmentIndex + 1) * 2
    }
    func targetActionValueChange(page:TKRubberIndicator){
        print("Target-Action : Page is \(page.currentIndex)")
    }

DimensionsPickerView

只需要几行代码，DimensionsPickerView 就可让您添加一个漂亮的视图，该视图可用于测量数据输入。可通过以下方式自定义占位符单位，字体颜色，间距和边框颜色/宽度：

sizePickerView.textFieldConfigureBlock = { index, field in
    switch index {
    case 0:
        field.placeholder = "w"
    case 1:
        field.placeholder = "h"
    default:
        break
    }
}
        
sizePickerView.pickerFieldConfigureBlock = { field in
    field.text = "m"
}
        
sizePickerView.tintColor = UIColor.red
sizePickerView.spacingBetweenValueFields = 0
sizePickerView.spacingBetweenUnitAndValues = 30
        
sizePickerView.layer.cornerRadius = 5
sizePickerView.layer.borderColor = UIColor.white.cgColor
sizePickerView.layer.borderWidth = 1.5
