Have you looked at this question? http://stackoverflow.com/q/7456835/62662 — oɔɯǝɹ, Nov 18 '12 at 19:41
Yes look this question, my problem is the Facebook SDK for iOS. I can't do the solution in this question. — abraaoan, Nov 21 '12 at 19:50
I'm having the same problem. Seems to happen if you use any appearance proxy settings. Hopefully there's a workaround? — Steve Simitzis, Dec 09 '12 at 09:22

I had the same problem and it seems (obviously) linked with the method [UIColor colorWithPatternImage:image];

So, I suggest to check each method that call colorWithPatternImage and comment each line that call that method one by one to find out the source.

For my case, it was the colorWithPatternImage on the UIPageControl in my AppDelegate.

A lot of question is about this problem. Example : UIApperance and various crashes or iOS 6 MFMailComposeViewController: Only support RGBA or the White color space, this method is a hack

For me this error was caused by the appearance settings on UITextField and UISwitch.

I have an abstract view controller subclass, which all of my view controllers inherit from, so I just specified to only set the appearance in my views that inherit from this view controller.

Like so:

[[UITextField appearanceWhenContainedIn:[BaseViewController class], nil] setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"bkg"]]];
[[UISwitch appearanceWhenContainedIn:[BaseViewController class], nil] setOnTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"bkg"]]];

I had the same problems and I fixed that by subclassing components. My case was:

UIColor *bkg = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bkg"]];
[[UICollectionView appearance] setBackgroundColor:bkg];

When I was trying to post something on facebook I received error, but then I created simple subclass of UICollectionView - let's name it MyGridView. So after modification my code was:

UIColor *bkg = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bkg"]];
[[MyGridView appearance] setBackgroundColor:bkg];

Then I changed views in storyboards to use custom component class MyGridView instead of default UICollectionView and everything worked - I had background I wanted and was able to post on facebook.

I think if your problem is similar to mine you could try this approach and subclass components you need (if they are intended to be subclassed of course).

Best regards
