从OC到Swift（7） - 资源名管理

• 参考Android的资源名管理方法

let img = UIImage(named: "logo")
let btn = UIButton(type: .custom)
btn.setTitle("添加", for: .normal)
performSegue(withIdentifier: "login_main", sender: self)

let img = UIImage(R.image.logo)
let btn = UIButton(type: .custom)
btn.setTitle(R.string.add, for: .normal)
performSegue(withIdentifier: R.segue.login_main, sender: self)

enum R {
    enum string: String {
        case add = "添加"
    }
    enum image: String {
        case logo
    }
    enum segue: String {
        case login_main
    }
}

extension UIImage {
    converience init?(_ name: R.image) {
        self.init(named: name.rawValue)
    }
}
extension UIViewController {
    func performSegue(withIdentifier identifier: R.segue, sender: Any?) {
        performSegue(withIndentifier: indetifier.RawValue, sender: sender)
    }
}
extension UIButton {
    func setTitle(_ title: R.string, for state: UIControl.State) {
        setTitle(title.rawValue, for: state)
    }
}

• 资源名管理的其他思路

let img = UIImage(named: "logo")
let font = UIFont(name: "Arial", size: 14)

let img = R.image.logo
let font = R.font.arial(14)

enum R {
    enum image {
        static var logo = UIImage(named: "logo")
    }
    enmu font {
        static func arial(_ size: CGFloat) -> UIFont? {
            UIFont(name: "Arial", size: size)
        }
    }
}
