Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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.
