Support UITextViews

[fatuhoku]

TOMSSuggestionBar doesn't work with UITextViews at the moment because it works with any UIControl <UITextInput>, which UITextView is not. In fact, UITextView is a subclass of UIScrollView <UITextInput>.

Problem: the suggestion bar normally observes the UIControlEventEditingChanged event, which is only officially emitted by UIControl subclasses. Yet we want TOMSSuggestionBar to support all sorts of controls, like

• UISearchBar
• UITextView
• UITextField

Looking at the class hierarchy their common superclass is UIResponder — this is too high up for UIControl behaviours.

~~Possible Solution: use https://github.com/andrewsardone/UITextView-UIControl~~

I agree, that would be nice! What do you mean by solution? Do you mean like UITextView+UIControl should be added as dependency to the project?

Hmm...

Yes — UITextView+UIControl it works brilliantly — from TOMSuggestionBar's perspective we may need to handle UITextView as a special case, and check for the availability addTarget:action: with respondsToSelector: or something horrible like that.

There's no level of abstraction where UITextView fits in neatly, basically. :(
