Xcode 4.5 - CopyPNGFile persists. Need new ideas

Question

I'm making an iPad app and it runs on the simulator, but fails when i try building it for the device.

the error is below:

These are the things i've tried to rectify this issue:

• went through every PNG file with Photoshop and saved them again w/o the interlace
• Deleted all the images in my Resources folder and added them again by dragging/dropping the images again
• Deleted ALL PNG images (left the JPGs) and it works...when i add one PNG, Xcode throws a hissy fit.
• Deleted the derivedData in my ~Library/Developer/Xcode
• quit Xcode and tried again
• restarted my computer and tried again.

i tried checking about the paths, but i'm not sure. Any ideas would be great please.

Addendum i also want to add that Xcode is throwing errors against its own [email protected] and Default.png!

Solution 1

This has NOTHING to do with png files missing but with a dynamic library you are linking against which isnt available on ios

Solution 2

In my case the error is resolved by going to

Build Phases -> Copy Bundle Resources

and removed all the duplicated entries of lunch images DefaultXX.png

Solution 3

You have to save your PNG files as NOT INTERLACED. For example, by using Photoshop, go to menu File->Save For Web and Devices. Unchecked the box of 'Interlaced' and save the file. Usually interlaced box is unchecked already. Hope that helps

Solution 4

Build Settings -> Search for Compress PNG Files and set to NO . This helped me

Solution 5

Well, i figured it out. The error log was a bit misleading since it says "Reason: Image not Found" right before the red highlight.

Turns out the "image" isn't the PNG or JPG, but the liberal.dylib as explicitly mentioned above. No idea how my perl library is gone...
