ios - UIImageView in full screen mode -


i think going wrong way need little help, please.

my goal:

i have uiimageview displays single image user. view in uiview. when user taps on image go full screen mode. current facebook , ebay ios apps on iphone.

once in mode, user can zoom on image , when done - swipe / down on image , goes last view.

problem

i not entirely sure how done. on apps mentioned, there new bar appears @ bottom of screen - bar allows user other actions. this, along swipe gesture makes me believe full screen mode presented new view controller. noticed scroll or down on ebay ios app, background starts change clear colour see view presented from. did not know possible uiviewcontroller when dismissing it? not sure how done.

i tried setting uiimageview full screen - misses else described above.

can point me in right direction. i'd appreciate it.

thanks!

i present new view controller in front of first 1 image full screen and, optionally, other controls. think effect of seeing presenting view controller behind obtained taking snapshot of , setting background of presented view controller (with method drawviewhierarchyinrect:afterscreenupdates: or other if < ios7, see this link).
