The final step is to build and run the application. In order to fully test the pinching and rotation recognition it will be necessary to run the application on a physical device (since it is not possible to emulate two simultaneous touches within the iOS iPad Simulator environment). Assuming provisioned device is attached (see [[Testing iOS 4 Apps on the iPad – Developer Certificates and Provisioning Profiles (Xcode 4)|Testing iOS 4 Apps on the iPad – Developer Certificates and Provisioning Profiles]] for more details) simply click on the Xcode ''Run'' button. Once the application loads onto your iPad device, perform the appropriate gestures on the display and watch the status label update accordingly.
