Mobile App Development: iOS (NEW)

The mobile application development scenario seems as much crowded as people trying to build the apps themselves. However, out of native Android, native iOS, PhoneGap and Appcelerator Titanium, native iOS mobile app development appears more complex than the others.

 This blog post, however, provides a brief outline in regard to iOS Mobile App Development as given below. Incidentally, most app development processes have the following primary building blocks.

  • Xcode – The development environment
  • Storyboards – For laying out and configuring the user interface
  • View controllers – That provide the basic logic for interacting with each of the views expressed in the storybooks
  • Navigation controllers – That enable the users to navigate amongst the diverse views

 Xcode

Most apps in Apple’s App Store are written in the Objective-C programming language, while developers characteristically use Xcode to develop their apps.

 However, you need to use Mac OS X to build iOS, as other operating systems are not supported, while the development tools that you will need iOS 7 SDK and Xcode 5 are free of charge. Also, you can run the app in iOS simulator, which again is part of the iOS SDK. Nevertheless, you need to pay some money annually to run your app on a device and make it available in Apple’s App Store.

 Nevertheless, once you have installed Xcode, you can create a new project. Select “Create a new Xcode project” from the screen via File → New Project in the menu. On clicking “Next” you will be presented with a dialog box to enter some necessary information in regard to your app. You also need to remember that the “Devices” settings restrict your app to run only on an iPhone or an iPad; while the “Universal” option enables you app to run on both. 

 Storyboards

Starting with iOS 5, Xcode has had storyboards, which enable you to lay out a series of view controllers and characterize the content for each. However, when an app is running on an iPhone or iPod Touch, the _iPhone version of the file will be used, while the  _iPad will be used for iPads. Needless to say, this permits a different layout to be used for  iPad’s larger display.

 View controllers and Navigation controllers

The screen functionality of iOS apps is grouped into a terminology known as View controllers. An app may have two view controllers – One for the principal screen while another for the settings screen. Basically, view controllers comprise the logic needed to interact with the controls on a screen. It also interacts with another constituent known as Navigation controller that helps provide the means for moving between view controllers. The navigation controller also provides the navigation bar that usually appears at the top of each screen. The controllers, incidentally, are pressed into a stack of views that are controlled by the navigation controller, while users move from screen to screen.
