this not formatted text. doing different. when space/enter typed in (and can detect uitextfield delegate), take written text , create view it.

the structure of view similar following:

+ view    + label text    + x (remove) button 

you add view container view. purpose of view keep search term views in list.

you can assign container view [uitextfield leftview].

of course, have handle removal, backspace etc.
