Action 增加触发方式, 高亮样式设置, 支持单击或按住

• 修复 UILabel 点击位置错误问题
• Action 增加触发方式, 高亮样式设置, 支持单击或按住

点击:

// 文本
let a: AttributedString = .init("lee", .action({  }))
// 附件 (图片)
let b: AttributedString = .init(.image(image), action: {
    // code
})

// 建议使用函数作为参数 语法上比直接使用闭包更加整洁.
func clicked() {
    // code
}
// 正常初始化
let c: AttributedString = .init("lee", .action(clicked))
let d: AttributedString = .init(.image(image), action: clicked)
// 字面量初始化
let e: AttributedString = "\("lee", .action(clicked))"
let f: AttributedString = "\(.image(image), action: clicked)"

// 获取更多信息 
func clicked(_ result: AttributedString.Action.Result) {
    switch result.content {
    case .string(let value):
        print("点击了文本: \(value) range: \(result.range)")
                
    case .attachment(let value):
        print("点击了附件: \(value) range: \(result.range)")
    }
}

label.attributed.text = "This is \("Label", .font(.systemFont(ofSize: 20)), .action(clicked))"
textView.attributed.text = "This is a picture \(.image(image, .custom(size: .init(width: 100, height: 100))), action: clicked) Displayed in custom size."

按住:

func pressed(_ result: AttributedString.Action.Result) {
    switch result.content {
    case .string(let value):
        print("按住了文本: \(value) range: \(result.range)")
                
    case .attachment(let value):
        print("按住了附件: \(value) range: \(result.range)")
    }
}

label.attributed.text = "This is \("Long Press", .font(.systemFont(ofSize: 20)), .action(.press, pressed))"
textView.attributed.text = "This is a picture \(.image(image, .custom(size: .init(width: 100, height: 100))), trigger: .press, action: pressed) Displayed in custom size."

高亮样式:

func clicked(_ result: AttributedString.Action.Result) {
    switch result.content {
    case .string(let value):
        print("点击了文本: \(value) range: \(result.range)")
                
    case .attachment(let value):
        print("点击了附件: \(value) range: \(result.range)")
    }
}

label.attributed.text = "This is \("Label", .font(.systemFont(ofSize: 20)), .action([.color(.blue)], clicked))"

自定义:

// 触发方式为 按住, 高亮样式为 蓝色背景色和白色文字
let custom = AttributedString.Action(.press, highlights: [.background(.blue), .color(.white)]) { (result) in
    switch result.content {
    case .string(let value):
        print("按住了文本: \(value) range: \(result.range)")
        
    case .attachment(let value):
        print("按住了附件: \(value) range: \(result.range)")
    }
}

label.attributed.text = "This is \("Custom", .font(.systemFont(ofSize: 20)), .action(custom))"
textView.attributed.text = "This is a picture \(.image(image, .original(.center)), action: custom) Displayed in original size."
