cs193p – Lecture #2 – Xcode 4

Please note, this blog entry is from a previous course. You might want to check out the current one.

Lecture #2 provides a short walk through of the Xcode developing environment. The first half of the lecture discusses the various classes of the model for the playing card game. The second is a life demonstration on how to start a project in Xcodes, placing buttons and labels in Storyboard and connecting them to the view controller.

At the end of the lecture the app called Matchismo displays a playing card and allows to flip it to show both sides of the card.

Assignment #0 is to follow the steps from the demonstration, add the model classes from the first half of the lecture and finally allow to flip through all cards of a deck.

To implement this last step, add a new property to hold the model of the game – the card deck – to the view controller. Don’t forget to include the model class:

iOS Dev – Lecture #3: Foundation Classes

The third lecture starts with a review of the last lectures followed by an introduction to data structures in Objective-C. Numbers are represented as int, float, double, NSNumber, booleans as BOOL, Strings as NSString and NSMutableString, dates as NSDate, and binary data as NSData. Further primitives are NSIndex and NSValue.
As collections there are arrays represented as NSArray and NSMutableArray, sets as NSSet and NSMutableSet, and dictionaries as NSDictionary and NSMutableDictionary.
In addition there are blocks for executable code.

Foundation classes are by default immutable which has the advantage of having no unwanted side-effects when passing objects to methods. To be changeable after initialization they have to be defined as Mutable.
