我只是想检查以确保我的Parse和Facebook SDK设置对于Facebook注册和登录是正确的，但我在测试期间遇到了一个问题，我在我的视图中设置了Parse注册功能加载，在过去构建应用程序时，我带来了验证Facebook凭据页面，但是我将该行打印到用户已取消的控制台，但我不确定为什么会发生这种情况。
打印的行= "Uh oh. The user cancelled the Facebook login."

如果您正确设置框架并遵循Parse的Facebook设置指南（https://parse.com/docs/ios/guide#users-facebook-users）的步骤，此代码将起作用。我在这个代码和你的代码之间注意到的两个主要区别是视图控制器中PFFacebookUtils登录功能的语法，而应用委托代表最后的func应用程序放在我的func applicationWillTerminate之前。

PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
PFFacebookUtils.initializeFacebookWithApplicationLaunchOptions(launchOptions)
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
func applicationWillResignActive(application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.

// Dispose of any resources that can be recreated.
}
let permissions = [ "email","user_birthday", "public_profile", "user_friends"]
@IBAction func loginButtonPressed(sender: AnyObject) {
PFFacebookUtils.logInInBackgroundWithReadPermissions(permissions) {
(user: PFUser?, error: NSError?) -> Void in
if let user = user {
if user.isNew {
println("User signed up and logged in through Facebook!")
} else {
println("User logged in through Facebook!")
}
} else {

}
}
}
}
希望这能解决你的问题！
