ioS beginnings part 2


Delegate file (h) example:

#import <UIKit/UIKit.h>

@class ViewController;

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (strong, nonatomic) ViewController *viewController;


Controller File (h) example:

@interface ViewController : UIViewController


Change the view controller example in your delegate:

@property (strong, nonatomic) UINavigationController*viewController;

Other choices:

First Steps into ioS

I had never done any programming in native mobile development with the ioS operating system prior to now. The way i found the Xcode on the iMac was searching the files on computer until i found out about cmd-space and entered xcode in the search box. There was a pdf on the computer named about Xcode 4.2

“Xcode is the complete developer toolset for creating applications for Mac, iPhone, and iPad”

In Xcode, you would start by doing File -> new project  and then single view application and click next where you enter a product name, a company identifier,  device such as iphone or ipad (dont click storyboarding, but click automatic reference counting), and then indicate where project goes and then you will click create.

After XCode loads the new project, you can click run to launch the simulator (or cmd-r).

You will see files AppDelegate.h AppDelegate.m ViewController.h ViewController.m ViewController.xib

Click on the sidebar the AppDelegate.h then on right at top click the tuxedu icon which will display now the AppDelegate.m beside the other file.

@interface AppDelegate : UIResponder <UIApplicationDelegate>

In the editor, if you click the command button the identifiers become URLs

On right side,

[ standard ] [ assistant] [ version ]            [Navigator] [Debug] [Utilities]                                  [open]
editor                                                                 view                                                         organizer

Utilities: toggle panel on right side, Debug : toggle panel on bottom, Navigator: toggle panel on left

bottom utilities:

  • file template library
  • code snippet library
  • Objects
  • Media library

iOS programming Field Of Dreams

I guess you could say 2012 has been my Field Of Dreams . In this year, I expanded my playing field of technical knowledge learning several new computer programming languages and tool sets.

I started year off learning Base SAS Programming with SAS 9.3. I also got exposed to SAS Enterprise Guide tool. My training in data continued with Data Flux by SAS. I thought about continuing my growth in the data with possibly getting certified.But, at the end of the day, what really interested me was creating GUIs.

In my next project, I was fortunate enough to enhance my front end development knowledge base by working with Sencha EXTJS4 javascript library. I really got to learn the in and outs of this library.

Next, I was part of another front end technology project with JQuery and KnockoutJS  technologies. Knockout uses the MVVC pattern which I had used before so it really fit well with me.

I have played around with BootstrapJS and even have used all different web service tools like Apache CXF and Spring-WS

This entry begins my exploration into ioS programming.
