iPhone and iPad SDK Programming Class
Programming the Apple iPhone and iPad devices using the IOS SDK can be challenging for beginners, but rewarding. This class
covers a broad overview of iPhone and iPad programming, including a coverage of Objective-C, UIKit framework, and other frameworks needed
for successful completion of iOS projects.
Lecture 4 - More UITableView and delegation
In this lecture, delegation was discussed in more detail. A homebrew delegate property was built from scratch in the sample
delegate-tutorial-ios-UCLA-201202.zip
.
UITableView was discussed in more detail, particularly recycling the UITableViewCell rather than building a new one with Alloc/Init each time.
Custom UITableViewCell objects were shown to be just specialized UIView objects that can be customized like any other UIView.
Specialized UIView objects are abundant in UIKit. We looked at some of the properties of UIImageView and UIScrollView in the
ios-tableview-tutorial-UCLA-201202.zip
demo, and how some of these views can be used in custom UITableViewCell objects.
This link to the Ray Wenderlich site has been both really helpful in completing specific tasks as well as an inspiration for app ideas. Check

Homework 4: Customizing UITableView
The purpose of this homework assignment is to gain more practice working with UITableView and UITableViewCell objects. Understanding
of these concepts will be fundamental to many(most?) applications on iPhone and iPad.
Create an iPhone application. Add a UITableView to the screen
that displays data you have stored as NSDictionary objects in an NSArray. Subclass UITableViewCell, and add custom views to the cell that best
display the NSDictionary objects found in your array.
Lecture 3 - Foundation Classes, drawing to the screen, delegation introduction
Homework 3: Investigating delegation and the UITableView
The purpose of this homework assignment is to gain more practice working with Objective-C and the Foundation classes. Additionally, it
will help you to become more familiar with delegation and the UITableView class. Hopefully you will have fun with the assignment and will experiment
outside of the homework requirements, for example by adding a custom view to the UITableviewCell or by changing the appearance of the cell.
This one could take up some time as some of the concepts may be unfamiliar.
Create an iPhone or iPad application using either the window-based or the view-based template. Add a UITableView to the screen
that displays data you have stored in an NSArray. After you get it working, use the appropriate delegate method to change the
height of each UITableViewCell to be 100 points. This
assignment will take some time, but will be a foundation for many iphone projects.
See the EditableTableView.zip xcode project for a good example of the elements required.
Lecture 2 - Objective-C, Foundation Classes and UIViews
In this lecture, Objective-C concepts were reviewed. Foundation classes such as NSString were discussed. The UIView runtime hierarchy was demonstrated.
UCLA_Day2_Demo201201 project was created
during class to demonstrate placing UIViews onto the screen.
Homework 2: UIViews
Create an iPad application with three UIViews overlapping one another. Set the alpha property of the views such that
the view on the bottom is still visible. Try completing the project both in code and with Interface Builder.
Lecture 1 - iPhone/iPad Platform and Objective-C
In this lecture, the iOS Platform is introduced using the iPad and iPhone. The Objective-C language and its basic
elements was introduced.
Objective-C is an extension of the ANSI C language which has been extended to include certain features centered around
object oriented programming.
The following Objective-C extensions that are discussed and should be reviewed: @interface, @class, @property, [] (square brackets), #import,
- (minus sign to mark an instance method), + (plus sign to mark an instance method).
UCLA_Day1_Demo project was created during class to demonstrate some of these concepts. See the readme.txt file in the iOS project for more information.
Homework 1: Getting Started
Send me an email with iOS in the subject line.
Read 'Learning Objective-C: A Primer' from Apple listed below.
Install the iOS SDK and XCode.
Create an iphone application using the view-based template. Display "Hello, World." on an instance of a UILabel. See UCLA_2012_HelloWorld.zip for a completed solution
to the homework assignment.
