生成钥匙串IBM Mobile First V 7.1

Question

我在iOS应用程序上使用IBM Mobile First V 7.1，问题是我的应用程序提交到商店后，Fabric开始向我发送奇怪的异常：

致命异常：无法生成密钥对。 钥匙串返回以下状态：-25308

每次我检查Crashlytics时，都会看到异常的不同跟踪堆栈，以下是我得到的异常之一：

经过一番调查和搜索，我发现了一些建议来启用“钥匙串共享”，下面的屏幕快照是我的应用程序应享有的权利：

请任何建议我该如何解决此问题，或者应该应用任何缺少的配置

致命异常：无法生成密钥对。 钥匙串返回以下状态：-25308

当手机锁定或在后台模式下运行时，如果应用尝试生成密钥对，则会发生上述错误。 似乎是您的应用在后台或手机被锁定时正在执行MFP请求。

当前，Mobilefirst iOS 7.x客户端SDK不支持在后台运行的MFP请求。 如果要访问不安全的资源，则可以使用非MFP API。
