Tips & Tricks: Installing an iPhone or iPad App with Provisioning Profile

To install an iPhone or iPad application on a limited number of devices, use the method of distribution called “Ad hoc”.


uses iTunes. First connect your iPhone to the computer. When your iPhone it detected by iTunes, click and go to the “Summary” tab.



Then click on “Serial Number”. The field will change to “Login (UDID)”.



You just have to copy the UDID “ + c” in mac or “Ctrl + c” under Windows. Now you can copy it to your e-mail.

Once you have communicated your UDID, just continue with the last two Ad Hoc distribution steps.

STEP 2 – The application is compiled and signed with the distribution profile. It is in this profile that devices authorized to the run application are listed.

STEP 3 - Deploying the application on your device.

Let’s now focus on this last step, where two files are needed:

• A compressed file containing the provisioning profile (valid for a limited time).

• A compressed file containing the application.

These two files (once unzipped) should be dragged on the iTunes icon:



Note: iTunes may ask you to replace the existing application or profile.

Once copied, you simply synchronize your device. Please note that a newly installed application will be displayed on the first application screen in on the first available spot, and not on the last application page.
