iphone - UIButton images look fine in IB but get stretched when displayed on app -


i'm developing enterprise app tracking mileage , maintenance company vehicles. i've added graphic buttons snazz bit. buttons way they're supposed on xib in ib, , on iphone other uiviews correct, on 1 particular uiview graphic images stretched way out of proportion vertically.

the first image below shows how it's supposed look, 3 graphics buttons @ bottom. second image shows how it's showing on phone. button on screen cap shows normally, can't counted on stay way.

it not consistent. calling view @ time may show image stretched or may not show image @ all. shows image normally, button looks below.

the development phone 4s running 6.1.3. views set retina 3.5 screen. xcode latest (whatever is).

the way it's supposed look

the way looks on phone

again, it's on 1 view problem shows up. there uiview on same view controller hidden when uiview shown. button graphics on other view fine. of other views , view controllers use same graphics on uibutton, without problem.

in interface builder (xcode) created view using 4.5-inch screen height.

but device seeing problem 5-inch screen. view resized fit.

and when that, autolayout constraints interface builder put on subviews take on determine they do. constraints causing heights change.
