title: iPhone/iOS: How to implement Drag and Drop for subviews of a Scrollview?
body: <p>I am having an horizontal scrollview in an <code>UIViewController</code>, where i have many images in small sizes. I am keeping the images in scrollview because the images are more, so user can scroll horizontally and choose images. But, the problem is, i have to select an image and drag and drop to that <code>UIViewController</code> view. But, since the images are in scrollview, drag and drop images into <code>UIViewcontroller</code>'s view is not working, not detecting the touch events too. 
  Please <strong>NOTE</strong>: If i don't have scrollview but just keeping the images also into <code>UIViewcontroller</code>'s view itself, drag and drop the images on the same screen, is working very well. </p>
  
  <p>How can I resolve this when I need to have scrollview and drag and drop images, any advice/help please?</p>
