I am putting my finishing touches on my application, and in doing that I created a launch image and some templates in light room. I have run the application through the simulator to test it out first, then went to test on my IOS Device through Xcode, which I have been doing the whole time through this application. It compiles and runs great through the simulator, but when I try and run it through my phone it gives me 13 issues. All of them are the same:

/CliffHanger/CliffHanger v5/CliffHanger v4.0/NoStarImage.png pngcrush caught libpng error:
Not a PNG file..

Could not find file: Xcode/DerivedData/CliffHanger_v4.0-
aqfzdgffvepdrdburawodkfmfqym/Build/Products/Debug-iphoneos/CliffHanger v4.0.app/NoStarImage.png
Command 
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/copypng 
emitted errors but did not return a nonzero exit code to indicate failure

I know this seems like a straight forward error, basically saying it is not a PNG file, but it is a PNG file.... This is why it is baffling me.....

  • Maybe worth looking at some of the suggestions in this question: http://stackoverflow.com/questions/5387671/ipad-png-crush-error – Nick May 27 '14 at 15:53
  • Have you tried opening it in something like Photoshop and saving it out again as a PNG? Also, make sure that your resources are also ticked to be included in the target. – aronspring May 27 '14 at 15:58
  • Did you lookup the exit code? What was it and it's description? – zaph May 27 '14 at 16:02
  • @Goodsum I went to get info and checked the extension there – user3669844 May 27 '14 at 16:09
  • If you fixed it, post the solution as an answer and accept it. – NobodyNada May 28 '14 at 00:36
  • I tried earlier, but wouldn't allow me. Hadn't been long enough – user3669844 May 28 '14 at 01:35
  • @user3669844 Just because the extension says it's a PNG doesn't mean that it actually is a correct PNG. That's why it would be a good idea to open it in an Editor and save it out as a new image. – aronspring Jun 03 '14 at 11:20

I figured out my issue. I went back and re-saved all of my images doing this : Open up image with Preview -> File > Export > Format change to PNG
