If you don't want to store pdf file to DocumentsDirectory then try following, hope it will work for you

NSString *binaryString =@"Binary code to change";
  myData = [NSData dataFromBase64String: binaryString];
  [self savePDF:myData];


- (void)savePDF:(NSData *)pdfContent
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask ,YES );
    NSString *documentsDirectory = [paths objectAtIndex:0];

   finalPath = [documentsDirectory stringByAppendingPathComponent:@"myPdf.pdf"];
    NSLog(@"%@",finalPath);
    NSURL *url = [NSURL fileURLWithPath:finalPath];
    //[pdfContent writeToURL:url atomically:YES];
     [aWebView loadRequest:[NSURLRequest requestWithURL:url]];
}

Comment //[pdfContent writeToURL:url atomically:YES]; line and check
