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，即使用户卸载所有应用程序并重新安装，而不是像identifierforvendor那样，该uuid也不会更改。我如何才能做到这一点Swift

Answer 1

您需要创建随机UUID并将其保存到钥匙串中。试试下面的链接

Answer 2

您可以使用下面的函数用于创建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 
}
