How do I get a thumbnail or saveable path from UIImagePickerController to use for a UIImageView?

Question

Could somebody please explain or show some sample code of how I can use get a thumbnail to be put into a UIImageView after the user selects a photo with UIImagePickerController?

Answer 1

Saving the URL can be problematic:

1. at least in iOS 4.x, the URLs is not guaranteed to be unique. They can be reused if user deletes/add pictures, which is obviously common. So, the URL you kept can point to a different picture in the future!
2. When the user updates to iOS 5, the URLs are no longer valid. UGH!!! Apple has rewritten Photo Library, with no backward compatibility.
