Facebook SDK 在 Swift 2 iOS 9 中登录时出错。

我试图在iOS 9和Swift 2中使用Facebook SDK制作一个简单的Facebook登录，但它总是抛出一个错误：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSTaggedPointerString containsObject:]: unrecognized selector sent to instance 0xa326874756162667'

这发生在usr/include/dispatch/once.h中，我无法独自解决它。有人有什么想法吗？

代码在此处：

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：以下是完整的错误堆栈：

@ChrisH 是的，我添加了，但是当我回答时，我添加的方式不正确，SDK没有检查它是否是一个字符串数组。 - Gabriel
@Gabriel，你能发一下可用的代码吗？我在使用Swift 2.0时也遇到了问题。 - Saty

我已经解决了这个问题。虽然文档中没有提到LSApplicationQueriesSchemes，但是我收到了缺少该项的错误消息。我将键和值“fbauth2”写入info.plist作为字符串，但它实际上是一个数组，而SDK在获取字符串数组的元素时没有进行任何检查。

不过，感谢大家提供的帮助回答。

非常感谢！ - AsTeR

请查看链接，了解如何在iOS9中集成FacebookSDK时将“fbauth2”添加到.plist。

FYI，我遇到了以下崩溃信息：

*** 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:

通过在.plist中添加以下内容解决了它。

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

我认为你的错误不在你发布的代码中。但是尝试删除"basic_info"权限，因为它已经被弃用，在iOS 9中可能会产生一些意外的值。

你可以阅读这个：

"以前，basic_info是一个必须要请求的权限，并暗示了public_profile和user_friends。随着新的Facebook登录，basic_info现在已经被弃用，不应该再请求。相反，明确地请求public_profile和user_friends（如果需要）."

谢谢，这会有所帮助，但问题仍然存在。 - Gabriel
