Memory Leaks when Scanner.h is used from an ARC file

[leifhanson]

Hello KurtCode and GitHub,
I have been working to leverage PDFKitten as a search for a project primarily using VFR Reader as it's PDF Viewer. I have been able to add the -fno-objc-arc flag to all the PDFKitten files to get them to build.
I'm using PDFKitten to search through the PDF and report if each page has a search term like so:
(Note: document is an instance of the VFR Reader ReaderDocument class)

#import "Scanner.h"
// Search Document and create Array that holds how many hits per page.
NSInteger intPageCount = [pageCount integerValue];
NSInteger i = 1;
CGPDFDocumentRef thePDFDocRef = CGPDFDocumentCreateUsingUrl((__bridge CFURLRef)(document.fileURL), document.password);

 for(i = 1; i < intPageCount; i++) {
    CGPDFPageRef searchPage =  CGPDFDocumentGetPage(thePDFDocRef, i);
    NSString *currentSearch = searchBar.text;

    Scanner *scanner = [Scanner scannerWithPage:searchPage];
    NSArray *selections = [scanner select:currentSearch];

    // Send the results of the search to the searchMarked NSMutable Array.
    if(selections.count > 0) {
        NSNumber *searchPageHit = [NSNumber numberWithInteger:i];
        [searchmarked addObject:searchPageHit];
    }
}

This code works, returning me an array of page numbers that contain my search term. However, every time I search quite a bit more ram is taken up. I suspect this is because I am instantiating the Scanner class from within a class using ARC, but the Scanner class itself uses MRC.

Here is output from Leaks after one successful search:

I have tried to convert PDFKitten to use ARC, and I'm afraid I'm just a littler too new with iOS to pull this off. I have also tried setting scanner to nil after it is used in every pass of the for loop, but it doesn't seem to make any difference. In addition, I have tried wrapping the for loop around an autorelease pool, and that didn't work either.

I will continue work, but any help would be greatly appreciated.

Thankyou KurtCode and GitHub community in advance for any advice or help you can offer.

Update: I have just noticed a pull request by user tarunbatta that has ARC fixes for PDFKitten. I will implement these to my PDFKitten base this evening and report back to this thread.
