I know there are options to customize UIActionSheet, but I notice many app's "share/send" options all look similar to this:
Is there some sort of template that makes this or something like this more automatically than creating all one's own buttons etc to try to mimic this? I tried to look through the docs (https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/UIKitUICatalog/UIActionSheet.html) and searching SO but didn't find anything. Can someone point me to the well-known and obvious sdk functions I would use to create this sort of sharing action sheet? Thanks a lot for any advice.
What you are looking for is this "UIActivityViewController", introduced in iOS 6, provides a unified services interface for sharing and performing actions on data within an application.
Apple's Doc is here: UIActivityViewController - Apple
