Try This

 NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,            
 NSUserDomainMask, YES); 
 NSString *docsDirectory = [path objectAtIndex:0]; 
 NSString *filePath = [docsDirectory stringByAppendingPathComponent:@“sample.pdf"];
 NSURL *pdfUrl = [NSURL fileURLWithPath:filePath];
 pdf = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
