In what's app (for example) when you click on the + sign next to the text input, you get this little menu tp pick from a number of sources, like the camera, photo library, documents, and so forth. Is this a build in controller or is that custom made. How would I go about recreating that ? (I want to be able to let the user pick an image from the camera, library, documents or a webview)

Thanks, now I know what to look for, but I am using UIKit, so now I search for Actionsheet and UIKit. Thanks!
