How do I specify exact positioning and font attributes an an iOS (iPhone / iPad) design document? -

-

my biggest issue designer working ios developers helping them translate psds iphone/ipad in pixel perfect manner.

my developer told me large company build app provided him design specification sheet ultra specific, outlined exact positioning of every element, font size, line height, etc. prepare design document specify:

  • exact positioning of elements
  • exact spacing between each element
  • font sizes
  • line heights of fonts
  • colors

what types of measurements should use each of above? suggest resources on web this? thank time.

if haven't looked @ apple human interface guidelines place start. required screen resolution information in there. can give developer required spatial info in pixels.

an iphone 5 have coordinate of (0,0) top left corner of screen , bottom right (320, 568).

  • for positioning elements, (x-coordinate, y-coordinate, width, height) in pixels.
  • spacing between elements: number of pixels
  • font sizes in points.
  • line height in pixels or em
  • colors in hex color codes
