What does "Receiver type 'CALayer' for instance message is a forward declaration" mean here?

I was able to duplicate your problem. This is what fixed it for me.
Add QuartzCore.framework to your project and this line to your .m file.
#import <QuartzCore/QuartzCore.h>

I'm porting a block of code from an iOS4 project to iOS5 and I'm having some troubles with ARC. The code generates a PDF from a screen capture.
PDF Generation Code
UIView *captureView; ... NSMutableData *pdfData = [NSMutableData data]; UIGraphicsBeginPDFContextToData(pdfData, captureView.bounds, nil); UIGraphicsBeginPDFPage(); CGContextRef pdfContext = UIGraphicsGetCurrentContext(); [captureView.layer renderInContext:pdfContext]; UIGraphicsEndPDFContext();
The renderInContext line
[captureView.layer renderInContext:pdfContext];
generates the following error.
Automatic Reference Counting issue Receiver type 'CALayer' for instance message is a forward declaration
Any ideas what is going on here?

NJones over 12 yearsJust to be clear, captureView is a UIView?

Jason George over 12 yearsYes, probably should have added that--captureView is a UIView.
