Xcode 4.5 - CopyPNGFile persists. Need new ideas

问题:

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 [e-mail] and Default.png!

回答1:

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

回答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

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

回答4:

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

回答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...

Check out this, this might be help you.Or delete bkg1.png from your project.

回答7:

The error can also occure if you save the file in an unexpected format of what it actually supposed to be. For instance, you save a *.png but with a .jpg encoding. Make sure that the file format is the one you actually want.

回答8:

Just try deleting the .png extension for the files which are causing you the trouble. Don't know how, but worked for me!

回答9:

For me this error was occurring when the png was listed in the copy bundle resources phase on the build phases tab. See https://stackoverflow.com/a/5659415/287403
