我如何使用Apple Keychain？ [英] How do I use Apple Keychain?

问题描述

我正在尝试使用 scifihifi-iphone（来自Github）存储和检索用户名和密码。但是，当我添加类 SFHFKeychainUtils 时，我收到以下错误：

I am using trying to use scifihifi-iphone (from Github) to store and retrieve usernames and passwords. However, when I add the class SFHFKeychainUtils I get the following errors:

ld: symbol(s) not found

我要遗漏什么？当我点击错误时，它不会把我带到代码中的任何地方。

What am I leaving out? When I click the errors, it doesn't take me to any place in the code.

推荐答案

添加 Security.framework ，然后重建。有时我发现我必须构建干净然后重建。

Add Security.framework, then rebuild. Sometimes I find I have to build clean and then rebuild.

要添加它，右键单击Xco​​de中的目标，然后添加 - >现有框架并选择（或导航） ）到 Security.framework 。

To add this, right click on your target in Xcode, then Add->Existing Frameworks and choose (or navigate) to Security.framework.
