如何在swift中生成特定于设备的唯一uuid

Question

我想生成一个设备特定的随机uuid，即使用户卸载我的所有应用程序并重新安装不同于identifierforvendor也不会改变。我怎样才能实现这一点是Swift

Answer 1

您可以使用以下函数创建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
}
