I want to develop ios share extention with custom callout. In apple documents
To provide a custom compose view instead of the standard one, deselect “Use standard social compose interface” in the Xcode target-adding pane. When this checkbox is deselected, the default SharingViewController class is based on NSViewController or UIViewController, depending on the platform you chose.
but I can't find the check box. Can anyone show me how to disable it and is there any good tutorials for share extention.
Thanks
