Hi everyone! I'm a manager in the app promotional servise, so want to share my experience. First of all, you should familiarize yourself with the iPhone operating system (iOS) and the iPhone user interface. This information is freely available on the internet. There are many forums and training material on the net for this. The next step is to make a sketch of the app that you would like to produce. You can experiment with various buttons, navigational schemes and texts. Use the iPhone (GUI) Photoshop template in order to design the app’s layout. If you aren’t familiar with this, you can use a third party designer for this part of the project.
The next step is to open XCode and write the code for your app by using Objective C. If you aren’t familiar with these programming languages, you can hire a third party programmer for the job. Don't forget to use mobile app promotion services
to make your app visible to customers! The final step is to submit the app to the app store once it is finalized. This is how to develop iPhone app the easy way.
