What units to use when creating a mobile application for iOS: pixel or point?

Question

User interface

I draw design in photoshop mobile application. The developer says that when programming, he uses points. I'm just starting to check all these techs. details. Explain, pliz, if I'm going to keep all my calculations in points, then what resolution should I set for iphone 5, 6, etc.

Answer 1

In your case, the Resolution parameter will not affect anything. This parameter is responsible for the resolution of printing on paper (roughly speaking, how many pixels the printer will put in 1 cm of the sheet) and how the image will look when you link one file to another. That is, if you have a file with a picture with a resolution of 144 px/inch and you link this file in Flash to a document with a resolution of 72 px/inch, then the linked picture will look 2 times smaller than it is in the original.
So just leave it at the default of 72 Pixel/Inch. This is the default value for screen graphics.

Answer 3

As an iOS developer and a bit of a designer rolled into one: set pixels and draw one layout on the largest iPhone, it's 1242x2208 px. I myself suffered with this issue until I was not experienced.
Then give the png to the programmer, saving the files as [email protected]
They are automatically scaled down and are very good for all iPhones. There are no pixels in iOS development, there are points, they are weakly logically connected with graphics and this is a mess, so do it in pixels, and if the developer asks you to do it in points, then he himself does not fumble. Then give him a psd template and let him typeset.
If there are orders for iOS development, write to me :) [email protected]
