Build app with Xcode 4 - it always show some error about PNG image

Question

When I build my app with Xcode 4 it always show this error message:

CopyPNGFile /Users/michaelchen/Library/Developer/Xcode/DerivedData/iMusicBox-boeawugacmha         


        

Answer 1

I solved this error, it's appear when you rename the images after put into the project, so for solve this problema first should delete the current images, rename files from finder and later copy this images into the project.
