我尝试使用iOS 9和Swift 2中的Facebook SDK进行简单的Facebook登录，但它总是让我错误：
***由于未捕获的异常终止应用＆＃39; NSInvalidArgumentException＆＃39;，原因：＆＃39; - [NSTaggedPointerString containsObject：]：发送到实例的无法识别的选择器 0xa326874756162667＆＃39;
它出现在usr / include / dispatch / once.h中，我不能单独解决它。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")
}
})

我已经解决了这个问题。由于文档中没有关于LSApplicationQueriesSchemes的任何内容，但是我收到了关于缺少它的错误消息，我将密钥和“fbauth2”值作为String写入info.plist，但它是一个数组，SDK试图获取字符串数组的元素，如果是数组，则不进行任何检查。
但是，谢谢你的帮助答案。

检查link以了解有关添加＆＃39; fbauth2＆＃39;的更多信息在iOS9中集成FacebookSDK时.plist。
仅供参考，
我正面临崩溃，并发出以下消息：
*** 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:

</array>

我认为您的错误不在您发布的代码中。但是尝试删除“basic_info”权限，因为它已被弃用，而在iOS 9中它可能会产生一些意想不到的价值。
您可以阅读：
“以前，basic_info是您必须要求的权限，并且暗示了public_profile和user_friends在一起。使用新的Facebook登录basic_info现在已弃用，不应该被请求。而是明确要求public_profile和user_friends（如果需要）。 “
