The view controller that manages an autocompletion view for suggesting common text completions while users type.
- iOS 8.0+
An autocompletion view can appear in place of the list of configuration items, just below the text view in the compose view. The compose view controller allows only one autocompletion view controller to be present at a time.
Note that your custom autocompletion view controller should set its
preferred property to an appropriate value.
SLCompose observes changes to the
preferred property and animates view size changes, if necessary.
