Combining View Controllers - iOS

One of the commonly asked questions that beginning iOS developers always asked is how to combine the tabbed-bar controller together with the navigation-controller. In the video above, I have demonstrated this by building a simple application. I have also made the source code available - you can download it here. Enjoy!

Displaying Status Bar Notifications in Android

Developers of Android are no doubt familiar with the Toast class, which displays a little pop-up containing whatever message you want to display to the user.

However, the Toast pop-up will automatically dismiss itself after a while, making it useful as a tool to provide timely feedback to the user (such as informing the user that a file has been saved successfully), but not a really good tool to use for some asynchronous action (such as telling the user that an incoming SMS message has arrived). For the latter, you can make use of the Status Bar Notification feature of Android, which displays a persistent notification on the status bar of your Android device. This notification can be dismissed when the user has read it, and thus this makes it a good tool for delivering notifications to the users to respond at their convenience.

In this article, I shall walk you through the steps to creating status bar notifications for your Android application.

Using your Borders Gift Card (Singapore) to offset against my courses

Recently, it was reported in the Singapore papers that due to the closure of Borders at Wheelock place, customers could no longer use its previously issued gift cards to make purchases at other branches. While this is a very disappointing news to a lot of customers, I have decided to follow the spirit of German Airline Lufthansa, who has very generously offered to let customers offset their air tickets value using their existing gift card.

As a book lover myself, I visit book stores regularly, especially Borders. I had been going there since I was a student, and had many fond memories. The smell and feel of books, and the aroma of coffee that fills the store has become a part of many peoples' lives.

Hence, I would like to offer existing Borders gift card holders to offset the fees for my courses using their existing Borders gift card. Every customer can offset a maximum of S$50 for any courses that they sign up. At this moment, here are the courses scheduled to run in Sep and Oct 2011:

September 2011

* 12 Sep 2011 - Objective-C Programming - S$499

* 13-14 Sep 2011 - Foundation of iPhone Programming - S$997

* 19-20 Sep 2011 - Android Programming - S$997

October 2011

* 3 Oct 2011 - Objective-C Programming - S$499

* 4-5 Oct 2011 - Foundation of iPhone Programming - S$997

Sample Project by Android Course Participant - Converts between degrees of Latitude and Longitude and MGRS

In last week's Android class at Fort Gordon, I have an outstanding participant - Chiam Krause, who took some jar files from the World Wind JAVA SDK and put together a coordinate converter that converts between degrees of Latitude and Longitude and MGRS. He has kindly shared the source code of his project on bitbucket. The project name is GridSquare.

Check out his blog here. Thanks, Chiam!

Foundation of iPhone Programming - 21-22 July 2011

Here is another fun iPhone programming course that I had conducted last week. As usual, after the class I think I have converted a few people to buy their first Mac in their life. :-)

And what a time to run the course, Apple just released Lion and a slew of new machines....Mac Mini and MacBook air.....

Learning Objective-C Programming (Singapore) - 19 July 2011

One of the hurdles that most developers encounter when starting out on iOS development is the language - Objective-C. While Objective-C is an extension of the C Programming language, its syntax left most of the developers who are deeply entrenched in Java and C# very confused. In addition, Objective-C in iOS requires developers to manage their own memory usage carefully so that memory is utilized efficiently. In fact, a little mistake in deallocating objects in Objective-C is enough to make your application spiralling out of control. It is with this intention that I am launching this new course on Objective-C programming.

In this one-day course, I will show you how to get started in Objective-C programming the easy way. Through this lab-intensive course, you will learn:

1. The basic syntax for calling properties and methods

2. How to declare and implement a class, its methods, and properties

3. Access Privileges

4. Initializers

5. How protocols and delegates work

6. The common classes used in Objective-C

7. The 101s of memory management for Objective-C in Cocoa/Cocoa Touch

8. And more!

If you are just getting started with iOS programming, this course is a must-have to ensure that you will become productive in the shortest amount of time.

Note that this is not an introductory class on programming. Attendees are expected to have some experience in programming using languages such as Visual Basic, C, C++, Java, or C#.

Venue: Mountbatten Square (Singapore)

Date: 19 July 2011 (Tue)

Time: 9am to 5pm

Fee: S$499 (nett)

Alumni for the iOS courses (Foundation of iPhone Programming and Advanced iOS Programming courses) will get a S$100 discount.

Inaugural weekend iPhone class - 2-3 July 2011

The first iPhone weekend class was a great success. :-) I had a lot of fun running the class and boy, we had an aspiring 9-year old iPhone developer!
