In the 990 release notes the following is stated:
iOS: Add “twitter” as a type for native.showPopup() — see daily API docs for details. Core: Also adds native.canShowPopup(name) which is mostly useful for “mail” and “sms”.
However the 990 API docs haven’t been updated. [import]uid: 70847 topic_id: 34194 reply_id: 334194[/import]
