P.S. Technology is only a small part of your app success. There is the business, sales and marketing that you need to think of too :). Which is why I also provide a bunch of free education on how to succeed on the App Store - http://kerofrog.com :).

A detailed look at Dapp’s iPhone Code Generator

May 13, 2010 0

We have had a few questions about how the code generation capabilities in Dapp work. I thought I would write a post answering some of the more common questions, however. If you just want to visually see how it works, then watch our Hello World tutorial.

Will Dapp be affected by the new clause in the iPhone developer agreement (clause 3.3.1) which states that iPhone apps can not be written on third-party platforms, and then subsequently converted into native iPhone code.

Clause 3.3.1 — Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).

Dapp has originally been written in Objective-C and is not affected by this clause.

How are these mockups converted into code?

The collection of mockup pages is converted into a group of code files, then compressed along with any images that the user has implemented within Dapp. Once compressed, Dapp opens up the default iPhone mail browser and attaches the compressed file. The user then just has to press send and the file is emailed to their predefined email address.

Can I reuse the code created by Dapp in my own projects?

Certainly. You may reuse the code for any personal or commercial purposes. All we ask is that if you redistribute the code in it’s original form that you do not remove or change the disclaimer.

I have just started to learn how to code my own iPhone apps, what do I have to do to get an iPhone app prototype up and running?

Nearly everything is provided for you. You just need to start a new project in Xcode then delete three files that were automatically created as part of the Xcode project. Drag and drop the files you uncompressed from the zip file provided by Dapp into your Xcode project and that’s it.  You can then press ‘Build & Run’ to run your iPhone app prototype. Our Hello World video tutorial will show you the process.

Naturally, experienced developers can simply drag and drop whichever individual files they require.
