当用户尝试使用Facebook在应用程序中进行身份验证时，用户在其中授予权限后，safari窗口不会消失。 Safari重新加载页面并保持空白，而不是解雇并且不将用户返回到应用程序
我的appDelegate方法正在关注
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
return true
}
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}
问题出在哪里？
