ios - 如何快速生成设备特定的唯一uuid

Question

我想生成一个特定于设备的随机 uuid，即使用户卸载我的所有应用程序并重新安装它也不会改变，这与 identifierforvendor 不同。我怎样才能做到这一点是 Swift

Answer 1

您可以使用以下函数来创建 UUID:

func getUniqueDeviceIdentifierAsString() -> String {
    var appName: String? = (Bundle.main.infoDictionary?[(kCFBundleNameKey as? String)] as? String)
    var strApplicationUUID: String = SSKeychain.password(forService: appName, account: "incoding")
    if strApplicationUUID == nil {
        strApplicationUUID = UIDevice.current.identifierForVendor.uuidString
        SSKeychain.setPassword(strApplicationUUID, forService: appName, account: "incoding")
    }
    return strApplicationUUID
}
