单选按钮组

iOS 平台缺失的单选按钮组组件。

用法

let radioGroup = RadioGroup(titles: ["First Option Title", "Another Option Title", "Last"])
radioGroup.selectedIndex = 0
radioGroup.addTarget(self, action: #selector(optionSelected), forControlEvents: .valueChanged)

SwiftUI 用法

RadioGroupPicker(selectedIndex: $selection, titles: ["One", "Two", "Three"])
    .fixedSize()

更改外观

以下属性可以在 Interface Builder 中、代码中或通过 UIAppearance 代理设置（例如，RadioGroup.appearance().titleColor = .red）。使用 SwiftUI 时，您可以在 RadioGroupPicker 初始化器中设置它们，或用作视图修饰符（例如，.buttonSize(32)）。

布局

radioGroup.isVertical = false           // default is true => buttons are stacked vertically
radioGroup.titleAlignment = .right
radioGroup.isButtonAfterTitle = true    // default is false => button left (leading) relative to title

颜色和字体

radioGroup.tintColor = .green       // surrounding ring
radioGroup.selectedColor = .red     // inner circle (default is same color as ring)
radioGroup.selectedTintColor = .blue  // selected radio button's surrounding ring (default is tintColor)

radioGroup.titleColor = .blue
radioGroup.titleFont = myFont

或使用富文本字符串

radioGroup.attributedTitles = [
    NSAttributedString(string: "Italic", attributes: [.obliqueness: 0.3]),
    NSAttributedString(string: "Underline", attributes: [.underlineStyle: 1]),
]

尺寸

radioGroup.buttonSize = 42.0
radioGroup.spacing = 12             // spacing between buttons
radioGroup.itemSpacing = 12         // horizontal spacing between button and title

按钮外观

RadioButton.appearance().size = 32              // height=width of button
RadioButton.appearance().ringWidth = 3
RadioButton.appearance().ringSpacing = 7        // space between outer ring and inner circle
RadioButton.appearance().selectedColor = .blue  // color of inner circle
