Mobile app development has gained grounds in the current web market. With an easy availability of incredibly effective SDKs(Software Development Kits) it has become quite convenient to build rich mobile applications in a time-saving manner. Apache Flex, formerly known as Adobe Flex has emerged as one of the best SDKs for development and deployment of applications for different mobile platforms including iOS, Android, BlackBerry, Windows Phone etc. Keep on reading this blog to know about developing finest iPhone applications using the Flex SDK.

Opportunities of iPhone app development using Flex SDK

After having tested the preview releases of Flex SDK, it has been found that the brand new features incorporated within it will work wonders for developing applications that can run on different iOS versions. With all the libraries functioning properly, it has ensured that the iPhone applications support accelerometer, gestures and several multi-touch features.

Getting started with iPhone app development using Flex

Usually, in case of iPhone Application Development Services, the preview versions of Flex namely: Burrito(Flash Builder) and Hero(Flex SDK) can be used for building a great Flex application for iOS7 and iOS8. You can choose to compile this app using the Adobe's Packager for iPhone. While developing the iPhone app, it is important to ensure whether the same supports the built in features of iPhone including: microphone, camera, GPS and many more. Interaction with the web is yet another crucial parameter that needs to be checked while developing the iPhone app using Flex.

A brief on the Packager for iPhone

In the above blog section, I've mentioned about using the packager for developing iPhone apps. For those of you who aren't familiar with what a packager is, here's an easy explanation. The Packager for iPhone is based on Adobe AIRA SDK 2.0.1. It enables the developers to re-use the existing code, fetching the same from the ActionScript 3 projects for creating native apps for the iPhone. After Apple removed the restrictions in its developer agreement, developers were able to convert ActionScript3 code-based applications into iPhone apps as long as the code was not being downloaded.


As a Flex developer, how can you use the Packager for iPhone?

With Packager, you can easily switch between the app and the phone mode for making calls and sending SMSs. Also, you can choose to upload and send graphics and text data using the HTTP requests. Other utilities of this Packager include the following:

  • Building tables, menus, diagrams and interactive networks
  • Launching and watching videos
  • Utilizing web servers in full-I tested mode

Difficulties encountered with the use of Packager

You can avail iPhone Developer for Hire or even Flex developers all over the world have encountered various problems associated with the working of the Packager. One of the major problems is the difficulty in accessing the iPhone's camera and the microphone. That means, the packager can't exchange data with the APIs. Yet another issue faced by Flex developers is non-receipt of the coordinates via the built-in GPS. The developers found that the desired API was available but it wasn't active. Moreover, there are some other performance issues that have been reported by the Flex app developers. Some of them include:

  • Flex application runs slower as compared to the native application
  • Size of a Flex applictaion is 2-3 times bigger as compared to that of a similar native application


It is vital for the Flex app developer to make a note that due to the frozen state of packager for iPhone for half a year, it still lacks some of the crucial functionality that's required for converting complex Flex applications into iOS applications.

With Adobe making continuous efforts towards improving the support for iOS development, it would be great for developers to build a full-featured interface that works well for developing iOS applications in Flex. Today, with most of the app components been optimized for working with mobile devices, the final beta release of Adobe Flex will bring in more possibilities for the app developers.
