CGPDFDocumentRef issue

[Fuzzball27]

I'm missing something obvious here, but I can't remember what...

Can someone explain to me why when I log "url" it comes out as expected, and when I create "document" I get error code -15?

NSString *filePathString = [filePath stringValue];
    CFStringRef URLString = (CFStringRef)CFBridgingRetain(filePathString);
    CFStringRef URLStringEscaped = CFURLCreateStringByAddingPercentEscapes(NULL, URLString, NULL, NULL, kCFStringEncodingUTF8);
    CFURLRef url = CFURLCreateWithString(kCFAllocatorDefault, URLStringEscaped, NULL);
    NSLog(@"%@", url);
    CGPDFDocumentRef document = CGPDFDocumentCreateWithURL(url);

Thanks!

I figured it out:
I should have been using "CFURLCreateWithFileSystemPath" not "CFURLCreateWithString"
