iOS联系人选取器

所以我正在从Sinch做一个教程！关于如何获取和呼叫联系人，那么它加载联系人就好了。问题是，无论何时我选择联系人进行调用，应用程序崩溃，Xcode都会在控制台上显示此错误。任何人都可以帮助我吗？iOS联系人选取器

最新的iOS版本？ –

即时通讯使用Xcode 8，但iOS部署目标为8.3，代码位于Objective-C –

它说，在最高层

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

发生了什么事那么找出你所呼叫的东西利用了applicationKey并找出为什么它是空白:)
