Xcode 2x，3x图像缩放不起作用？

Question

I have an image called shareIdea. I created @2x, @3x and named them shareIdea@2x and shareIdea@3x. I have added them to xcode as you can see in the image here:

However when I compile and run. The images used along my toolbar are still the 22px. So I'm unsure what to do or how to fix it.

Answer 1

In each device you have a image proportion that the SO will request, they will use the "maximum" available for each one.

• 4, 4s, 5, 5s and6 (Max @2x)
• 6 plus (Max @3x )
