ios - FBSDKLoginManager.loginWithReadPermissions 不在 iOS 上调用处理程序

简化一下，代码是这样的:

func login() {
     NSLog("Will login with read permissions")
     FBSDKLoginManager().logInWithReadPermissions(
            ["public_profile"],
            handler: {
                (result: FBSDKLoginManagerLoginResult!, error: NSError!) -> Void in
                    NSLog("Handler is called")
            })
     NSLog("Returning from login")
}

调用时，它会生成以下日志语句:

2015-05-25 11:35:07.886 MyApp[1213:646722] Will login with read permissions
2015-05-25 11:44:22.048 MyApp[1213:646722] Returning from login

(上述语句之间的较大时间差异是由于我使用调试器单步执行 logInWithReadPermissions 的内部结构。在没有调试器的情况下运行不会改变行为。)

我已经在安装了 Facebook native 应用程序并登录的设备上尝试过此操作，我也曾在没有 native 应用程序的设备上尝试过此操作，但我根本没有访问过 Facebook。我也在模拟器上试过这个。我得到了相同的结果。

我假设这是一个同步调用，但为了以防万一，我尝试在调用线程中无限期地等待——处理程序仍然没有被调用，并且设备上没有发生任何可见的事情。

我打开了我能找到的所有日志记录:

FBSDKSettings.setLoggingBehavior(
   [FBSDKLoggingBehaviorAppEvents,
    FBSDKLoggingBehaviorInformational,
    FBSDKLoggingBehaviorAccessTokens,
    FBSDKLoggingBehaviorUIControlErrors,
    FBSDKLoggingBehaviorGraphAPIDebugWarning,
    FBSDKLoggingBehaviorGraphAPIDebugInfo,
    FBSDKLoggingBehaviorNetworkRequests,
    FBSDKLoggingBehaviorCacheErrors,
    FBSDKLoggingBehaviorDeveloperErrors])

然后，在启动时，我得到以下任一信息:

无论哪种方式，我的处理程序都不会被调用，但 logInWithReadPermissions 函数返回正常。

我已经在我的 AppDelegate 中实现了以下所有内容:

func application(application: UIApplication,
                 didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

   FBSDKApplicationDelegate.sharedInstance().application(
       application,
       didFinishLaunchingWithOptions: launchOptions)
}

func applicationDidBecomeActive(application: UIApplication) {
    FBSDKAppEvents.activateApp()
}

func application(application: UIApplication,
                 openURL url: NSURL,
                 sourceApplication: String?,
                 annotation: AnyObject?) -> Bool {

    return FBSDKApplicationDelegate.sharedInstance().application(
        application,
        openURL: url,
        sourceApplication: sourceApplication,
        annotation: annotation)
}

我的 Info.plist 中有这些行:

<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fb140xxxxxxxxxxxxx</string>
        </array>
    </dict>
</array>
<key>FacebookAppID</key>
<string>140xxxxxxxxxxxxx</string>
<key>FacebookDisplayName</key>
<string>MyApp</string>

上面有什么我遗漏的吗？如果没有，我该如何进一步调试呢？我可以打开或关闭任何日志记录吗？我在 XCode 或 Facebook 端的应用程序设置中有任何人能想到我可以查看的内容吗？

最佳答案

你说:

"I tried waiting indefinitely in the calling thread -- the handler is still never called, and nothing visible is happening on the device."

这个调用绝对不是同步的，如果你让主线程在一个紧凑的等待循环中忙碌，那么它就无法“给你回电话”。

另一件要检查的事情是确保您的应用程序委托(delegate)没有同时实现

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {

如果您在应用委托(delegate)中实现此方法，则其他实现将被忽略:

func application(application: UIApplication,
                 openURL url: NSURL,
                 sourceApplication: String?,
                 annotation: AnyObject?) -> Bool
