Running the project on an iOS device

In this section, we will create a video synthesizer project and run it on iOS Simulator and an iOS device. The project will be based on code we developed in Chapter 3, Adding a GUI and Handling Keyboard Events.

Tip

If you have no source code for the project we made in Chapter 3, Adding a GUI and Handling Keyboard Events, please get it from the example code files for this book.

To develop iOS projects, you must have a computer running OS X (such as MacBook, Mac Pro or Mac mini). This is mandatory before you go ahead with this section.

To deploy the project on a real iOS device and publish it on the Apple App Store, you need two things:

An iOS device (iPhone, iPad, or iPod touch)
An iOS Developer License from Apple (this costs $99 per year; you can buy it at developer.apple.com/programs)
Note
You can still develop a project and run it in iOS Simulator without this license but can't upload it on your iOS device and publish on the App Store.
