How to read pdf file from document directory in iPhone?

Question

Currently i am working in iPhone application, i have an pdf file in resource folder (Local pdf file) then i read that pdf file (paper.pdf) successfully, below i have mentioned read local pdf file for your reference.

Example:

CFURLRef pdfURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("paper.pdf"), NULL, NULL);
pdf = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
CFRelease(pdfURL);

Then i have tried to store pdf file (from URL) in NSDocument directory, stored successfully.

NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://www.msy.com.au/Parts/PARTS.pdf"]];

 NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
 NSString *documentsDirectory = [paths objectAtIndex:0]; 
 NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"myPDF11.pdf"];
 [pdfData writeToFile:filePath atomically:YES];

Then i tried read that pdf file (from NSDocument directory) but i didn't know that, please help me.

Thanks in Advance
