我找到了一些相关的帖子：
UIImagePickerControllerDelegate to Swift?
how to capture camera with UIImagePickerController in swift?
但它们都不适用于beta 3，因为UIImagePickerControllerDelegate已更改：
func imagePickerController(picker: UIImagePickerController!, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]!)
我的问题是如何从info Array获取UIImage对象？感谢

它是一个字典，用UIImagePickerControllerOriginalImage
let image = info[UIImagePickerControllerOriginalImage] as UIImage
