user interface - PSD pixels to ios points -

-

i received design (photoshop) layout designer in pixels. how convert points required ios?

i tried substituting pixles points thinking may 1:1 conversion on coding in app design looks weird (bigger expected).

table header height example: tried converted 32px+40px of psd = 72 points in ios in comps table header little bigger navbar (which ofcourse 44 points).

should designer providing layout in points rather pixels?

if not how convert pixels points ios?

converting pixels points depends on target ios device. on 1x device (ipad 1 & 2, iphone 3gs), 1 uikit point == 1 pixel. on retina devices (ipad 3 , up, iphone 4 , up), 1 uikit point == 2 pixels.
