CHITouchySuperButton

CHITouchySuperButton 是一个可以直接使用的 UIButton 子类，它允许你仅用几行代码就能创建和自定义一个高度交互的按钮。 这个类兼容 UIView 的可动画属性：transform，alpha，center，frame，bounds 和 backgroundColor。 这个类被广泛用于所有 SongShift 应用中，使其感觉更具互动性。 此软件包仅与 iOS 应用兼容，并以 iOS 10+ 为目标。

安装

要安装 CHITouchySuperButton，你必须手动添加 源文件，或使用 Swift Package Manager。 要使用 Swift Package Manager 安装，请按照 Apple 官方文档 中的说明进行操作。

  1. 打开你的应用程序项目设置，选择你的应用程序目标，然后导航到其 General 窗格。
  2. 单击“Frameworks, Libraries, and Embedded Content”部分中的 + 按钮，然后选择本地软件包的库以将其链接到你的应用程序目标中。
  3. 通过单击“Add Other”，然后单击“Add Package Dependency”来添加此包，然后粘贴包的 GitHub URL。

用法

CHITouchySuperButton 的用法非常简单。 首先导入模块

import CHITouchySuperButton

然后，像创建标准 UIButton 一样创建 CHITouchySuperButton 的实例。 这可以通过界面构建器或以编程方式完成

let button = CHITouchySuperButton(frame: .zero)
// add a target for .touchUpInside just like a normal UIButton
button.addTarget(self, action: #selector(buttonPressed(_:)), for: .touchUpInside)
button.backgroundColor = UIColor.systemBlue
button.layer.masksToBounds = true
button.layer.cornerRadius = 13
button.setTitle("Touchy Super Button", for: .normal)
button.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(button)

view.addConstraints([
    button.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 30),
    button.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -30),
    button.centerYAnchor.constraint(equalTo: view.centerYAnchor),
    button.heightAnchor.constraint(equalToConstant: 65)
])

现在，要告诉 CHITouchySuperButton 你希望它在按下和释放时如何显示，你需要实现两个 TouchBlock

// tell CHITouchySuperButton what to do when pressed down
button.buttonPressed = { button in
    // modify transform, alpha, center, frame, bounds, or backgroundColor
    button?.transform = CGAffineTransform(scaleX: 0.92, y: 0.92)
}

// tell CHITouchySuperButton what to do when released
button.buttonReleased = { button in
    // do NOT put your actions here, just your animations. use addTarget to add an action.
    button?.transform = .identity
}

就是这样！ 上面的代码将产生位于本自述文件顶部的“形变”效果。

默认情况下，touchy 按钮在释放时会产生触觉反馈。 要禁用此功能，只需将你的 CHITouchySuperButton 上的 hapticFeedbackEnabled 设置为 false 即可。
