Instance Method

activateContextHelpMode(_:)

Places the receiver in context-sensitive help mode.

Declaration

func activateContextHelpMode(_ sender: Any?)

Parameters

sender

The object that sent the command.

Discussion

In this mode, the cursor becomes a question mark, and help appears for any user interface item the user clicks.

Most apps don’t use this method. Instead, apps enter context-sensitive mode when the user presses the Help key. Apps exit context-sensitive help mode upon the first event after a help window is displayed.
