for more customizability planning build button comprised of uiview , tap gesture recognizers subviews, i'm not sure. possible create uiview accessible uibutton?

accessible in context refers ui elements can used using apple's accessibility features, such voiceover (see illustration below).

for example, visually impaired person not able see view or subviews, or buttons matter; accessibility software "voiceover" built every ios device read her/him kind of object , title, "button: continue" (if button title "continue").

you can see tap gesture recognizer not read voiceover , less "accessible".
