*How Tos* in iPhone App Development (baby steps) – updated
I’m just starting to learn how to write objective-c for iPhone application. Objective-c is very new to me, but I’ve known java and c# pretty well. So most of posts that I’m going to upload on iPhone app will be notes to myself, so I won’t forget and use it as references later.
#1 reference – how to instantiate an object!
In objective-c, “alloc” is used instead of “new”. Here’s a simple text on how to create an object. (assuming we are not using singleton’ized class)
1 2 | UIColor mycolor = [[UIColor alloc] initWithRed:0.32f green:0.37f blue:0.84f alpha:1.0f]; |
I was so confused with the objective-c grammar when I first started learning objective-c. As I looked at the grammar more and more, it became much more clear now luckily.

Programming flow for the iPhone application is like this:
- calls main method
- in main, calls “UIApplicationMain” with applicationDelegate class as a parameter along with other parameters
- applicationDelegate creates UIWindow and root level UIViewController
Those three steps are pretty much mandated in order to launch something in your iPhone app for the sake of MVC design pattern.
