I have no images called \"\" (nothing). I\'ve gone through the .xib file of the screen where this pops up and can\'t find anything that would cause this. Anybody who have ha
Just for reference, this problem is also caused by using .jpg images and referencing them inside of storyboards/nibs. iOS 8 appears to be able to handle the proper type checking between jpg and png images at runtime. However, on iOS 7 and below you will need to manually set the image in the code and remove the image reference inside of the storyboard to get rid of the warning.
Remember you need to manually set the .jpg when referencing jpg images.
[self.imageView setImage:[UIImage imageNamed:@"yourImage.jpg"]];
