#The Cocoa Touch Framework#

  • Series of frameworks that include:
    • UIKit (based on Application Kit)
      • Provides key objects needed to run apps
      • Coordinates handling of user input
      • Coordinates display of content on screen
    • Foundation
    • Game Kit
    • iAd
    • Map Kit
      • Core Audio

#Model-View-Controller (MVC) Design Pattern#

  • Separation of logic
  • Defines roles objects play in app
  • Defines the way objects communicate with each other
  • Abstraction
  • In short: modifying either model or view has no effect on on another
  • The value of MVC, think about it: what if Apple comes out with another device which the view is programmed differently than on the iPad or iPhone?

#Your First App#

  • See SimpleApp project

#Interface Builder#

  • Good for building widget-based interfaces
  • .xib (pronounced NIB file)
  • Not good for games, anything that requires the drawing surface

#iOS Simulator#

  • The best simulator we got!
  • Very different than hardware
  • Typically, networking is faster on the simulator
  • Can't simulate multitouch (e.g., the three-finger salute variety)

#Windows, Views, and Widgets#

  • A window is an instance of UIWindow; an empty surface to host one or more views
  • Apps must have one window
  • A view is an instance of UIView:
    • Defines content for a rectangular region of window
    • For drawing, interaction, animation, etc.
    • A view can hold a number of widgets
  • Widgets: buttons, labels, sliders, pickers, etc.
