Question

当我直接将我的应用程序构建到我的iPhone时，我可以将项目存储在keyChain中，但如果我将其存档并将其发送到ItunesConnect并且有人使用testFlight下载它，则不会将该项目存储在keyChain中

以下是他尝试访问钥匙串的日志：

修改

这就是我用来在钥匙串中放置东西的内容：https://github.com/jrendel/KeychainWrapper/blob/master/KeychainWrapper/KeychainWrapper.swift

我不知道它是否使用kSecClassGenericPassword。这就是我将信息放入钥匙串的方法：

KeychainWrapper.setString(self.username.text, forKey: "username")
KeychainWrapper.setString(self.password.text, forKey: "password")

我用它来取回它：

if let u = KeychainWrapper.stringForKey("username") {
        username = KeychainWrapper.stringForKey("username")!
        password = KeychainWrapper.stringForKey("password")!
}

Answer 1

您应检查设备上无法访问钥匙串的控制台，并查找指示钥匙串访问问题的日志。这听起来像权利问题。查看此常见问题解答，了解如何解决您可能在控制台中看到的问题：

我认为您可能没有填写钥匙串项目的所有必要信息。如果您使用的是kSecClassGenericPassword，那么您需要同时填写kSecAttrAccount和kSecAttrService

Answer 2

这似乎是Swift编译器的一个错误。

如果您在目标的“构建设置”中将“发布”的“优化级别”更改为“无”，则该工作
