Midterm Topics

Everything we've covered so far is fair game, but focus on the following:

• Core primitive data types: int, float, BOOL
• Common structs: CGSize, CGRect
• Core Foundation classes: NSArray, NSDictionary, NSString
• Core UIKit Classes: UIView, UILabel, UIButton, UIImageView, UIColor
• Format strings
• All about properties: what they do for us, strong v. weak, stack v. heap
• Patterns: MVC, Target-Action, Notifications, Delegation and Protocols
• CoreLocation and MKMap frameworks

Be able to write:

• An Objective-C class with:
  • private ivars
  • public properties
  • method declarations:
    • that have a return value
    • that take 0 parameters
    • that take 1 or more parameters
  • method implementations (see above)
  • an init method
  • a description method
• A C function that takes arguments and returns a value
• Code that concatenates 2 strings
