Good time of day!

I am writing an application and I need the following: when you first start the application, the very first thing that the user sees after the download window is the language selection window and offers to log in via your facebook account.

How this can be implemented so that in subsequent launches of the application this window no longer appears.

I am a beginner, I can not yet doctrine, practice is not enough, help others! )

  • Would write on what write the application something, and then in different systems it is implemented differently - aknew
  • Yes, the question was on objective-c, implemented through the use of NSUserDefaults - pupkinn

If this data is missing, does this indicate that this is the first launch? Give out the window if there is no data, that's all.
