Is there a way to suppress gesture recognition? What inspires me to ask this question is watching my grand-daughter, who is a toddler, using an iPad. Quite often, she will accidentally invoke a gesture recognizer that switches apps. An example of this would be the four finger gesture where you can slide an app out of the way.
For a "child proof" app, is it possible to suppress these? Failing that, is it possible to suppress switching to another app? At first thought, that seems out of scope of an app, but maybe there is a way to do it.
You don't need to do it in your app, because it is an accessibility feature of iOS 6. It is called "Guided Access" and you can enable it in Settings -> General -> Accessibility in the Learning section.
