Coding an application with Twitter API use to be a lot of mess prior to iOS 5. There was no inbuilt support from Apple side. For even basic message tweeting, you had to integrate third party libraries like SAOAuth and  MGTwitterEngine.

Writing Calculator for iPhone iOS in Xcode

I believe, to learn any language with GUI capabilities one must take Calculator as an assignment. I’ve build that in FoxPro, VB 2.0, Oracle Power Objects, Java AWT, Swing and JavaScript. Now it is time to build the same for Apple iPhone using iOS Programming. What I am surprised to see is that this is really not challenging. It will not take much of your time to build Calculator to basic Level.

This calculator program is capable of taking input of any number with number buttons, Clear the screen, Perform Addition Subtraction, Multiplication and Division. No Negative numbers yet.
