title: How do I programmatically snap a UIPickerView to the bottom of the parent view it resides in, in iOS 7/Objective-C?
body: <p>So I have UICollectionViewController and have added a UIPickerView to controllers view. Right now the UIPickerView sits beneath the nav bar.</p>
  
  <p>How do I make it automatically take the bounds of the view it's within, whether on an iPhone 4 or iPhone 5 and use this to snap the UIPickerView to the bottom of it's parent.</p>
  
  <p>Regards</p>
