navigationbar - iOS navigation bar item image size

Question

I want to customize my NavigationBar button and using my own images.

The question is what the size should be?

I found that the button size should be 40*40, so the image should be 80*80 for retina?

Answer 1

These are the sizes that the documentation recommends for custom icons now.

• @2: 50 x 50
• @3: 75 x 75

Create two images of the above pixel sizes and then add them to a new image set in your Assets.xcassets file. (Apparently the @1 size is no longer needed.)

Alternatively, you could use a universal vector image (pdf) (see here and here). This has been my preference recently.
