Facebook SDK登录在swift 2 iOS 9中引发错误

Question

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

***由于未捕获的异常'NSInvalidArgumentException'终止应用程序，原因：' - [NSTaggedPointerString containsObject：]：无法识别的选择器发送到实例0xa326874756162667'

它发生在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")
    }
})

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，如果它是一个数组，则不进行任何检查。

但是，谢谢你的帮助答案。

Answer 2

查看链接以了解有关在iOS9中集成FacebookSDK时将“fbauth2”添加到.plist更多信息。

仅供参考，
我正面临崩溃，并收到以下消息：

*** 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:

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。

你可以读到这个：

“以前，basic_info是你必须要求的权限，并且暗示了public_profile和user_friends在一起。使用新的Facebook登录basic_info现在已被弃用，不应该被请求。而是明确要求public_profile和user_friends（如果需要）。”
