title: Create a gallery for local app content in iOS
body: <p>My app takes some videos and pictures and stores them in the Application Home/Documents folder. I want to create a gallery that will open and display (and playback) these items. I looked into MPMediaPickerController and it looks like the only option for data source there is the Photos Album.</p>
  
  <p>It looks like I will have to go with creating UICollectionView. Is this the right way to do this or is there another way similar to MPMediaPickerController but with setting the source to an array of data objects?</p>
