Iphone graphice design

I designed buttons are not clear in corners in my app i开发者_StackOverflow社区n iphone, what is the photoshop resolution for designing Iphone icons and other navigation icons?

Here you'll find all the information you need: Apple documentation on creating icons and other artwork

Use the 300 resolution when you are doing the Photoshop design.

The specific resolution isn't actually what they're looking at. What matters is the number of pixels in the document. so 1" x 1" @ 100 is the same as 2" x 2" @ 50

Also here are some great scripts for exporting assets ready for iPhone use.
