集成Facebook SDK后,我在启动应用程序后立即收到以下错误: "无法识别的选择器发送到实例"
我做了什么:
我使用适用于iOS 8.2的XCode 6设置了一个简单的简单视图控制器应用程序,并将Facebook iOS SDK与Cocoapods集成在一起。
我通过"入门"部分并将nesseccary代码放入AppDelegate并更改.plist-File。 运行应用程序时,它会立即停止使用"无法识别的选择器" -Error。
我也试过了Example-App" Scrumptious"从Facebook-SDK,运行非常好。我将Scrumptions中的代码构建到我的应用程序中,并且遇到了和以前一样的错误。下面我将发布callstack。
Facebook建议-ObjC切换到链接器标志来解决这些错误。但是这个国旗已经确定了(我认为cocoapods已经确定了)。
我该怎么办?缺什么?
这是callstack:

答案 0 :(得分:2)
看看你的plist-File。它必须包含FacebookAppId,DisplayName和URL Schemes。如果只有一个丢失,你会收到这样的错误。
以下是我使用Facebook-API正常运行的应用之一:
