A.2. Preparing your iOS device for development

When you develop applications for iOS devices, you naturally also want to test them on an actual device and not just in the simulator. Because iOS applications have to be digitally signed in order to run on a device, you have to get a digital certificate from Apple and install a Provisioning Profile on your device. Let’s do that next.

A.2.1. Creating a certificate

First, launch an application on your Mac called Keychain Access (it’s in the Applications folder inside the Utilities folder). In the menu bar, select Keychain Access > Preferences, and set both Online Certificate Status Protocol and Certificate Revocation List on the Certificates tab to Off. Next, select Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority...” from the menu bar. You should see the window depicted in figure A.2.
