UIImagePickerController continue to select image
<p>I know UIImagePickerController can only select one image from library each time. When user select one image, UIPickerController will disappear. But I noticed the app "Good Reader", when it launchs UIImagePickerController, after user choose one image, it prompt a small window says "processing the image", but UIImagePickerController does not dissappear which will let the user continue to choose other images.</p>

<p>I do not know how this can be realized?</p>

<p>Welcome any comment.</p>

<p>Thanks interdev</p>
