Model-View-Controller (MVC) architecture in iPhone applications development

The structure of iPhone applications code is based on the Model-View-Controller (MVC) architecture. It benefits the iPhone applications development or the object-oriented programs as a whole in many ways. MVC–based programs can be adaptable to changing requirements and their objects more reusable.

The main goal of the MVC architecture in iPhone applications development is to separate business logic, such as your application’s data and the rules that govern your application, from the user interface (presentation layer).

The MVC architecture considers there to be three types of objects:
1. Model objects
2. View objects
3. Controller objects

A goal of a MVC based application also should be to reuse as many objects as possible. View objects and model objects should be highly reusable and application-specific behavior should be implemented in controller objects.

Design Guidelines:

• Dependency should be minimal in case of all the MVC architecture implementations
• MVC roles can be merged in an object although making that object acts as both the controller and view object. Then it would be called a view controller. In the same way, you can also combine model-controller objects. Following MVC architecture makes code more reusable, understandable and extendable
• It is good design that a view object use controller object as mediator to know about changes in an model object

iOS Jailbreaking

In technical essence, jailbreaking of an iPhone means making the mobile device free from the limitations imposed on it by the carrier – AT&T or Verizon and Apple. The User installs a software application on the computer, and then transfers the same to the iPhone, where it ‘breaks open’ the iPhone’s file system to allow the User to modify it. The devices included are the iPhone, iPod touch, iPad and 2nd fen Apple TV. The jailbreaking phenomenon in iPhone programming is a form of privileged escalation, and the term has been applied to privilege the escalation on the computer systems too.

Why Jailbreaking?
It lets the iPhone user do everything from customizing look of your iPhone to installing third-party applications and customizing ringtones, etc. It even lets you to unlock your phone so one can use it with a carrier other than the one from which you purchased it.

Why NOT Jailbreaking?
Once you do it, you’re on your own. You may have voided the warranty, so cannot rely on Apple to fix your problems that you encounter. All the applications that Jailbreak your phone are unauthorized. And so, who knows you might end up using your smartphone as a mere paperweight.

iPhone - Bluetooth Programming

Two iPhone apps can be made able to communicate with each other using the Wireless protocol - Bluetooth. Some industry people say that Bluetooth is somewhat an expired technology, but still there are many Users in India, who have separately installed Bluetooth (via and as a private application) in their iPhones. The Bluetooth apps can be downloaded from the store to the iPhones. These applications can interact with each other over more than one iPhones at a time such as gaming or productivity reports, etc.

This protocol for iPhone programming is basically used for gaming, image sharing, and as a walkie-talkie software.

Moreover, Apple provides an application bundle named as ‘Bluetooth Mania.’ It allows the Users to use the iPhone as a walkie-talkie. In detail, the User needs not to call someone on the iPhone. Instead, if the other iPhone User is within the Bluetooth range, you can always use this app to communicate with each other too. Further, the smart iPhone developers can customize this app too.

IPhone programming: Implementation of Views Controllers

The User interface has always been the most important part of any project in iOS projects development. Because of the different screen sizes, apps often need separate versions of their interface for each device on a larger screen. This means creating new view hierarchies but might also mean creating completely different view controller objects to manage those views.

Following these below tips for View controllers will result in an interface that feels more supportive to the iPhone developers:
> Define separate view classes for iPhone and iPad devices
> Always put the shared code in a base class and then implement custom subclasses to address issues
> If using single view controller for both  platforms, your code must support iPhone & iPad screen sizes
> Your view controller must be able to handle differences between the two platforms

Cloud Server: Concept of Mobile Programming

A Cloud Server is the main and server-side component of the infrastructure that is located in the ‘Cloud.’ From the mobile apps developers point of view, a cloud server stays in between the mobile device and the actual cloud data services, which is being mobilized. The Cloud Server provides a Java based API to expose the data services. The system provides mobile-oriented features like data sync, real-time push, etc.

The Cloud Server further has 2 concepts:

1. A ChannelA Channel serves as a gateway for integration the on-device model/data objects with the server-side backend storage systems such as relational databases, Enterprise systems like CRMs, etc. It provides an interface to expose the backend data. The catch here is to keep a channel which is purely data-oriented component.

2. A MobileServiceBeanA MobileServiceBean frees up the developers from all the RPC concerns like security related issues, network connections, checking/unchecking payloads, etc. It exposes some coarse grained business process to the on-device Mobile App, and provides a simple request/response based synchronous invocation mechanism.
