FBSDKLoginManager.loginWithReadPermissions不在iOS上调用处理程序

FBSDKLoginManager.loginWithReadPermissions不在iOS上调用处理程序,第1张

概述简化,代码是这样的: func login() { NSLog("Will login with read permissions") FBSDKLoginManager().logInWithReadPermissions( ["public_profile"], handler: { (resu 简化,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")}

调用它时,它会生成以下日志语句:

2015-05-25 11:35:07.886 MyApp[1213:646722] Will login with read permissions2015-05-25 11:44:22.048 MyApp[1213:646722] Returning from login

(上面的语句之间的大的时间差异是由于我使用调试器来逐步执行logInWithReadPermissions的内部.没有调试器的运行不会改变行为.)

我已经在安装了Facebook原生应用程序并且我已登录的设备上试过这个,我在没有本机应用程序的设备上试过这个,我从来没有访问过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,我试着在调用线程中无限期地等待 – 处理程序仍然没有被调用,并且设备上没有任何可见的事情发生.

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,我得到这样的:

或这个:

无论哪种方式,我的处理程序从未被调用,但logInWithReadPermissions函数返回正常.

我在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)}

我在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>

我在上面遗漏了什么?如果没有,我该如何进一步调试呢?我可以打开或关闭的任何日志记录?我在XCode或Facebook方面的应用程序设置中的任何人都可以想到我可以看到的东西?

解决方法 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,如果你让主线程忙于紧密的等待循环,那么它将无法“回电”.

要检查的另一件事是确保您的应用程序委托也没有实现

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

如果在app delegate中实现此方法,则将忽略其他实现:

func application(application: UIApplication,annotation: AnyObject?) -> Bool
