[iOS Development] How to Create Hello World Application for iOS using Xcode

I’ve recently taken it upon myself to get into iOS development. I use iOS on a daily basis on my iPhone and got an interest to start developing for the devices as well.

Starting Point

• Basic knowledge of  C and hopefully some Object Oriented programming, iOS SDK uses Objective-C, which is a superset of the C language.
• iOS development is done using 2 main programs, Xcode and the Interface Builder (there is also the iOS simulator, which is used to test your apps at first).
• All development toolkit which run solely on Intel based Macs. So unfortunately if you’re a PC and not a Mac you’re a bit stuck.

Development Environment

Firstly let’s have a look at those programs you’ll be using to develop for iOS, starting with Xcode.Open  the xcode application (easiest way to do so is to use spotlight and type xcode and run the application from there, or you can find xcode in /Developer/Applications/).

Step -1 :
Opening splash screen for Xcode which gives you the option to start a new project or open an existing project.Select “Create a new Xcode project”, click that and you’re brought to below figure.

Step -2 :

 Next you can able to see different projects you can create. For this "Hello World" example select the “View based application” and save it in a directory you’re happy with (I’ve set up a developer directory for all of my projects to go into).

Step - 3 :

Once you’ve chosen a name for your project the next screen you’re brought to workspace of Xcode.

iRamTestAppViewController.xib” is the Interface Builder file that Xcode created for you when you selected a ‘View-based application’; the XIB file contains your view, and ‘iRamTestAppViewController.m’ is your view controller, but that’s not important for now.Double clicking “iRamTestAppViewController.xib” will open your xib file in Interface Builder.

Step - 4 :

Drag a label from the library to your view.By default Interface Builder will add a View to your XIB which will display when your XIB file is opened. 

To the left of your view in Interface Builder, there is a window called “Library”, the library contains objects for controls and views you can use in your interface. For this tutorial we just need a label, so find the ‘Label’ object in the library, then click and drag it onto your view.

Step - 5 :

To Customize the labelChange the text on the label to “Hello World’ by double clicking the label and typing “Hello World” and hitting return. While the label object is still selected, use the Attributes Inspector (to the right) to change some of the appearance attributes of the label, in this  example I changed the font size to 58, and added a shadow with a 1 pixel horizontal and vertical offset. 

Step - 6 :

Now you set to go .In Xcode click the ‘Build & Run’ button at the top of the Project Window, this will build your app bundle and run the app in the iPhone simulator.

 

From this Tutorial, you can able to create simple application for iOS using XCode. Coming week will walkthrough about Objective -c, Cocaco Touch Frameworks and UI designs.

Mac OSX Lion - In-depth Review and Final Thoughts

Finally the new Big Cat "Lion" in Apple OSX family came out from the cage and roars loudly with new features to take OSX into next level.Apple bridged a gap between what’s been called mobile OS, (or in their case, iOS), and desktop OS, further turning what it means to own a computer with killer desktop experience.

Installation                  

Install Mac OSX Lion is so easy now , just go to Mac App Store and you can search "OSX Lion" then download the entire OS by just like an app from App Store.

 

Starting with Scrolling Gestures

When your computer starts for the first time after having had Lion fully installed, you’ll be able to see the  window shows the demo about  the  entire scrolling gestures.
Swipes between pages in PDF,Word 

                        

Swipes between Full Screen Apps

Mission Control , swipes up Three or Four Fingers to see many desktops 

App Expose to switch between apps by swipes down Three or Four Fingers

                              

Like iOS , you can see the page flow of installed Mac Apps by spread with thumb and  Three or Four Fingers.

Multiple Desktops

In OSX Lion now you can able to create multiple desktops and each one of them with their own desktop wallpaper, open windows, docked apps, and open apps.

Dashboard

You can access dashboard  by three-finger-swiping all the way to the left, or by clicking it in Mission Control. If  Widget production is going to increase, Widgets will have to be placed in the Mac App Store.
LaunchPad
When you see the Launchpad, you will  instantly understand why this version of Mac OS is being called a bridge between Apple’s desktop operating system and mobile Apple’s iOS, as seen on iPhone, iPad, and iPod Touch.

Just like in iOS, you’re also able to take one app and place it atop another to create a folder with the two inside, this folder then up for additional apps in the future.
Misson Control

Mission Control is accessible by you by clicking the Mission Control icon in your dock, or by swiping three fingers upward on your trackpad.Another use you might consider for Mission Control and your multiple desktops is giving each member of your family a different desktop to work with.

Another great use of  this Mission Control is make you WANT to use a lot of windows at once. which makes the best use of the operating system’s abilities.

Finder

“All My Files” is an File Explorer by being a separation of every single file you have on your computer in one place, separated by filetype and the Show All” button for each category, this being a viable option for me to separate videos.

AirDrop

AirDrop, an extremely simple system in which you can connect peer to peer with people running AirDrop on computers near you.Apple mentioned t this functionality works out to about 30 feet, this being the range of MacBooks can see one another. This system is not connected via Wi-fi, again, it’s peer to peer, meaning you don’t need the internet at all to make it work, just two Apple computers.

Spotlight

Spotlight desktop search to  find anything and everything and this new iteration in Lion shows not only results on your computer aslo searches the webpages, music, web searches searches, and more. Mouse-over any result to see a preview. 

Very simple and a very handy  option for opening apps, browsing the web, and finding old emails.

Safari

Safari in Lion gets the new Scoop with Full screen and use a three finger to back and forth, or forward and backward.Instead of clicking the back button or the forward button, you have only to swipe with two fingers to the right or to the left.You can  also able to pinch to zoom or double-tap to zoom.

Mail, Contacts & Calendars 

iCal and iChat                                                                                                                                                                                  iCal get the  giant boost once the iCloud is active and running, and iChat being promoted by the in-browser connection to your accounts is a massive potential plus.

 Mail

Major UI change in Mail app with new search feature.

Contacts

Lot of change has happened to the functionality, again, of Address Book, but it looks a whole lot more enticing.

Final Thoughts

• OSX Lion eyes on the notion that Mac OS X Lion would be like iOS for desktop
• Full Screen App takes the ease of productivity.
• Trackpad Touch Gestures makes your day to day activities easier.
• App Store makes u get lot more Lion Featured Full Screen Apps.
• OSX Lion is worth to update for new desktop experience

iOS 5 Beta 2 - Features and Changes

iOS 5.0 beta 2 was released yesterday and there have been a few new features spotted. Most of these are extremely minor changes, however there is one major feature that was turned on in the below


New Notification Lock-Screen Look

Not so much new, however it is a minor change. When your phone receives a notification it will display the most recent one as a bubble. Then, when the notification has been there for a minute or so, it turns into the bars like the previous beta.

WiFi syncing
This feature was a major one featured at WWDC ’11. Really, it works as expected with no errors. I restored my iphone last night and set it to WiFi sync; this morning, all my content was on it. It was truly amazing and is definitely the way of the future.

Crisper Font in Messages 

Messages application it has a new font looks a lot crisper. You can see a picture of that below.

iCloud icon changed

In iOS 5beta 1, the icon for iCloud in settings was originally purple. Not anymore, the purple icon has been replaced by the brushed aluminum one, and it looks a lot better.
