Help, How to get indirect reference to a page object with CGPDF

[gly25]

CGPDFPageRef pdfPage = CGPDFDocumentGetPage(pdfRef, pageNum);
CGPDFDictionaryRef pageDictionary = CGPDFPageGetDictionary(pdfPage);
CGPDFArrayRef outputArray;
if(CGPDFDictionaryGetArray(pageDictionary, "Annots", &outputArray))
{
    int arrayCount = 0;
    arrayCount = CGPDFArrayGetCount(outputArray );
    if(arrayCount>0)
    {
        for( int j = 0; j < arrayCount; ++j )
        {
            CGPDFObjectRef aDictObj;
            if(CGPDFArrayGetObject(outputArray, j, &aDictObj))
            {
                CGPDFDictionaryRef annotDict;
                if(CGPDFObjectGetValue(aDictObj, kCGPDFObjectTypeDictionary, &annotDict))
                {   
                    CGPDFDictionaryRef aDict;
                    if(CGPDFDictionaryGetDictionary(annotDict, "A", &aDict))//page 1 returns here
                    {
                        CGPDFArrayRef dArray;
                        if(CGPDFDictionaryGetArray(aDict, "D", &dArray))
                        {
                            CGPDFObjectRef dObj;
                            if(CGPDFArrayGetObject(dArray, 0, &dObj)){
                                CGPDFDictionaryRef annotDict;
                                if(CGPDFObjectGetValue(dObj, kCGPDFObjectTypeDictionary, &annotDict))
                                {

                                }
                            }
                        }
                    }
                }
            }
        }
    }
}

I read Pdf32000_2008.pdf, it write

A destination defines a particular view of a document, consisting of the following items:

•The page of the document that shall be displayed

•The location of the document window on that page

•The magnification (zoom) factor

Example: [page /XYZ left top zoom]

But in my code

CGPDFArrayGetObject(dArray, 0, &dObj)

is a CGPDFDictionaryRef.

93 0 obj << /Type /Annot
/Subtype /Link
/Rect [71 717 190 734]
/Border [16 16 1]
/A <<
/Type /Action
/S /GoTo
/D [3 0 R /FitR –4 399 199 533]
> > endobj

How can I get like /D [3 0 R ...]

How can I get a indirect reference to a page object.

I'm very very very very hope an answer, thank you very very very much.
