First, storyboard and xib

• Contrast:
• The same point: all in the form of IB programming, you can quickly build a GUI.
• Differences: Xib focuses on single-file (separate controller or view) editing, storyboard focuses on multi-page correlation. Storyboard can intuitively comb out the logic between pages, and all page jump logic can be in -(void) Prepareforsegue: (Uistoryboardsegue *) Segue Sender: (ID) sender ; method is completed to facilitate the unified management of data between interfaces.
  
• Note: Do not use code to initialize a window in the Appdelegate-application:didfinishlaunchingwithoptions: method. Set the created storyboard to Maininterface in the application configuration general.
