Facebook SDKlogin在Swift 2 iOS 9中抛出错误

我尝试使用iOS 9和Swift 2中的Facebook SDK进行简单的Facebooklogin，但总是抛出一个错误：

***由于未捕获的exception“NSInvalidArgumentException”，原因：' – [NSTaggedPointerString containsObject：]：发送到实例0xa326874756162667的无法识别的select器'

它发生在usr / include / dispatch / once.h中，我不能单独解决。 有人有什么想法吗？

代码在这里：

import FBSDKCoreKit import FBSDKLoginKit let loginManager = FBSDKLoginManager() loginManager.logInWithReadPermissions(["basic_info", "email", "user_likes"], fromViewController: self.parentViewController, handler: { (result, error) -> Void in if error != nil { print(FBSDKAccessToken.currentAccessToken()) } else if result.isCancelled { print("Cancelled") } else { print("LoggedIn") } }) 

更新：这是完整的错误堆栈：

提前致谢。

Answer 1

我已经解决了这个问题。 由于在文档中没有关于LSApplicationQueriesSchemes的任何内容，但是我得到了关于它缺less的错误消息，我把这个键和“fbauth2”值作为string写入了info.plist，但是它是一个数组，并且SDK试图获取string数组的元素，如果它是数组，则不进行任何检查。

不过，谢谢你的帮助。

Answer 2

查看链接 ，了解更多关于在iOS9中整合FacebookSDK时将“fbauth2”添加到.plist信息。

仅供参考，
我正面临着一个消息：

 *** Terminating app due to uncaught exception 'InvalidOperationException', reason: 'fbauth2 is missing from your Info.plist under LSApplicationQueriesSchemes and is required for iOS 9.0' *** First throw call stack: 

并通过在.plist添加以下内容来解决它

 <key>LSApplicationQueriesSchemes</key> <array> <string>fbapi</string> <string>fb-messenger-api</string> <string>fbauth2</string> <string>fbshareextension</string> </array> 

Answer 3

我认为你的错误不在你发布的代码中。 但尝试删除“basic_info”权限，因为它已被弃用，在iOS 9中，它可能会产生一些意想不到的价值。

你可以阅读这个：

“以前，basic_info是你必须要求的一个许可，并且将public_profile和user_friends一起隐藏起来。新的Facebookloginbasic_info现在已经被废弃了，不应该被请求，而是明确地询问public_profile和user_friends（如果需要的话）。
