iOS 联系人选择器

Question

所以我正在做 Sinch 的教程！关于如何获取和呼叫联系人，好吧，它可以很好地加载联系人。问题是每当我 select 要呼叫的联系人时，应用程序崩溃并且 Xcode 在控制台上显示此错误。有人可以帮我吗？

它说的是最顶层发生的事情

inchAppToPhoneTutorial[1143:42160] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Parameter 'applicationKey' is invalid (was '')'

所以弄清楚你在哪里调用使用 applicationKey 的东西并弄清楚为什么它是空白的:)
