锁匠错误:Locksmith.LocksmithError.interactionNotAllowed [英] Locksmith error: Locksmith.LocksmithError.interactionNotAllowed

问题描述

我们正在使用Locksmith来保存Keychain的用户数据.最后，一切正常，但由于某些原因，我们收到了崩溃，错误为Locksmith.LocksmithError.interactionNotAllowed.

we're using Locksmith to save user data for Keychain. In our end everything works as it should but for some reason we receive crashes with the error Locksmith.LocksmithError.interactionNotAllowed.

遵循发生崩溃的代码:

func updateUserAccessToken(forAccount account: String, token: String) {
    var userAccessToken = Locksmith.loadDataForUserAccount(userAccount: account) ?? [String: Any]()
    userAccessToken["token"] = token
    try! Locksmith.updateData(data: userAccessToken, forUserAccount: account)
}

为什么上面的代码对其他用户崩溃?直到.现在我们无法复制上述崩溃.很感谢任何形式的帮助.谢谢！

Why is the code above crashes for other users? 'til . now we can't replicate the said crash. Any help is very much appreciated. Thanks!

更新: 因此，我们最终能够复制此崩溃，这是因为我们正在锁定设备的同时访问钥匙串.我发现您可以更改钥匙串的可访问性选项"，但是我不确定如何在Locksmith中进行操作.有人吗?

UPDATE: So we finally able to replicate this crash, and it's because we're accessing the keychain while the device is locked. I found out you can change the Keychain's "accessibility option" but I'm not sure how to do it in Locksmith. Anybody?

推荐答案

我发现，如果您使用的是协议基础方法，则更改可访问性选项更容易.但是很遗憾，我们的应用程序未使用它.所以我要做的就是创建一个扩展，如下所示:

I found out that if you're using a protocol base approach changing the accessibility option is much more easier. But unfortunately our app doesn't use it. So what I did was I created an extension as follow:

extension Locksmith {
    fileprivate static func loadDataForUserAccount(userAccount: String,
                                                   inService service: String = LocksmithDefaultService,
                                                   accessibleOption: LocksmithAccessibleOption) -> [String: Any]? {
        struct ReadRequest: GenericPasswordSecureStorable, ReadableSecureStorable {
            let service: String
            let account: String
            var accessible: LocksmithAccessibleOption?
        }

        let request = ReadRequest(service: service, account: userAccount, accessible: accessibleOption)
        return request.readFromSecureStore()?.data
    }

    fileprivate static func updateData(data: [String: Any],
                                       forUserAccount userAccount: String,
                                       inService service: String = LocksmithDefaultService,
                                       accessibleOption: LocksmithAccessibleOption) throws {

        struct UpdateRequest: GenericPasswordSecureStorable, CreateableSecureStorable {
            let service: String
            let account: String
            let data: [String: Any]
            var accessible: LocksmithAccessibleOption?
        }

        let request = UpdateRequest(service: service, account: userAccount, data: data, accessible: accessibleOption)
        return try request.updateInSecureStore()
    }
}

注意::更改可访问性选项" 可能会使您无法访问以前使用默认可访问性选项" 保存的数据.如果需要这些数据，则可能需要单独处理.

NOTE: changing the "accessibility option" may loss your access to the data previously saved with the default "accessibility option". If you need those data you may need to handle it separately.
