title: Detecting unknown number of simultaneous taps
body: <p>I'm working on an app that will be used by two to four people using a single iPad. Each of them will be tapping with one or more fingers. They are not coordinated with each other. So gestures could be recognized as any number of taps. Do I need to create separate gesture recognizers for each number of fingers scenario? I will also need to know the locations of each of the taps.</p>
  
  <p>I know the iPad recognizes a maximum of 11 touches, and this app will probably run into that limit. So if I can avoid having to code 11 separate recognizers, that would be great.</p>
