Using the following code, the ctx is not correctly being created. It remains nil:
#import <QuartzCore/QuartzCore.h>
@implementation UIView(PDFWritingAdditions)
- (void)renderInPDFFile:(NSString*)path
{
CGRect mediaBox = self.bounds;
CGContextRef ctx = CGPDFContextCreateWithURL((CFURLRef)[NSURL URLWithString:path], &mediaBox, NULL);
CGPDFContextBeginPage(ctx, NULL);
CGContextScaleCTM(ctx, 1, -1);
CGContextTranslateCTM(ctx, 0, -mediaBox.size.height);
[self.layer renderInContext:ctx];
CGPDFContextEndPage(ctx);
CFRelease(ctx);
}
@end
In the console it shows:
<Error>: CGPDFContextCreate: failed to create PDF context delegate.
I've tried several different paths so I'm fairly certain that is not the problem. Thanks for any advice!
