ios - App size with different iPhone models -

-

i have problem app, app simple , created in viewcontroller of iphone 5s size.

but problem here, when run app on iphone 6 mode ore 6 plus or 4s, size doesn't change in proportion iphone size, fixed background problem dragging background image view , clicking "center horizontally in container", "center vertically in container", "equal widths", "equal heights".

but when try same small round buttons, app destroyed , button deformed.

seems you're hardcoding ui positions , sizes in app. take auto layout. name suggests, allows have same ui layout on devices support, without hardcoding frames.
