Show downloaded pdf with CGPDFDocumentRef

Question

I have a problem and I hope someone can help me.

I upload a pdf file to DocumentDirectory

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, TRUE);
NSString *documentsDirectory = [paths objectAtIndex:0];
studioPath = [[documentsDirectory stringByAppendingPathComponent:@"test.pdf"] retain];
ASIHTTPRequest *request = [[ASIHTTPRequest requestWithURL:[NSURL URLWithString:@"http://testURL.com/test.pdf"]] retain];
[request setDownloadDestinationPath:studioPath];

this is not all the code, but I understand that you understand what I mean.

After that I will show this pdf

CGPDFDocumentRef pdf;
CFStringRef fullPathEscaped = CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)studioPath, NULL, NULL,kCFStringEncodingUTF8);

CFURLRef docUrl = CFURLCreateWithFileSystemPath (NULL, fullPathEscaped, kCFURLPOSIXPathStyle, FALSE);  
pdf = CGPDFDocumentCreateWithURL(docUrl);

but it always crashes when I use the internet url instead of studioPath for PDF, which it works, but I would not download the pdf file anymore.

Try this one

 CFURLRef pdfURL = (CFURLRef)[[NSURL alloc] initFileURLWithPath:[documentsDirectory stringByAppendingPathComponent:source]];
    //file ref
    CGPDFDocumentRef pdfRef = CGPDFDocumentCreateWithURL((CFURLRef) pdfURL);
