Curtain 是一个 Swift pod，可以帮助您实现计时器背景动画。实现起来非常简单，使用提供的选项来自定义背景颜色、背景填充方向和退出动画。

示例

使用 Curtain 来动画化您的计时器。自定义您的退出动画和背景颜色来提供更好的用户体验。支持垂直和水平两种方向。

安装

CocoaPods

Curtain 通过 CocoaPods 提供。要安装它，只需将以下行添加到您的Podfile中

pod 'Curtain'

Carthage

Carthage 是一个去中心化的依赖管理器，构建您的依赖并提供二进制框架。

为了使用Carthage将 Curtain 集成到您的Xcode项目中，在您的 Cartfile 中指定它

github "igorsquadra/Curtain"

运行 carthage update --platform iOS 来构建框架，然后将从 Curtain.framework 拖到您的Xcode项目中。

在您的目标应用程序的“构建阶段”设置选项卡中，点击“+”图标，选择“新建运行脚本阶段”，并将框架路径添加如下所述，见Carthage 快速开始步骤 4、5和6

使用方法

要实现Curtain，创建一个BackgroundProgressView并将其添加为子视图。

import Curtain

// Initialize the progress view.
var backgroundProgressView: BackgroundProgressView!
backgroundProgressView = BackgroundProgressView.init(frame:
    CGRect.init(
        x: 0,
        y: 0,
        width: 0,
        height: 0
))

// Add it as subview.
view.addSubview(backgroundProgressView)

使用setup方法自定义以下参数

// Setup your progress view.
backgroundProgressView.setup(
    withDirection: .vertical, // Direction type should be .horizontal or .vertical.
    withTime: 15.0,
    view: view.frame,
    color: UIColor.init(red: 109/255, green: 212/255, blue: 0/255, alpha: 1.0),
    initialSize: 0, // Set initial size, default is 0.
    autoreset: true, // If false the progress view remains full at the end of timer.
    resetType: .linear // The reset animation should be .linear or .fade
)

调用start方法以开始动画。使用time参数以新时间开始动画（如果为nil，则使用在setup方法中传递的时间）。

// Start progress animation
backgroundProgressView.start(withTime: 35.0)

使用reset方法将进度视图重置为动画状态。

// Reset progress animation
backgroundProgressView.reset()
