键盘没有出现，facebook sdk

Question

i am having a problem, i want to call the facebook sdk, so i can post from my app. When I was calling the dialog for the login from a pushed view it was ok, but now i am showing a view using presentModalViewController and from that view i want to call the facebook login dialog. but now the keyboard does not appear. i didn't change anything just the way i present the view. do you have an idea what can be happening ?

I am using splitview controller, from the detail view (that is modaly presented) i call the facebook sdk what should be wrong ?

在你的应用程序委托的函数didFinishLaunchingWithOptions添加以下代码

[self.window makeKeyAndVisible]
