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("Han
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 permissions 2015-05-25 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：

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？
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, openURL url: NSURL, 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,
openURL url: NSURL,
sourceApplication: String?,
annotation: AnyObject?) -> Bool
