    <p>I am using the following code. it always gets into the destination string if. it does not go to get page number loop. if pdf found destination string then it will not go to else part. so how can i get the page number from destination string. You can see an example of the code below. Thanks in advance.</p> <pre><code>- (OutlineItem*)recursiveUpdateOutlines: (CGPDFDictionaryRef) outlineDic parent:(OutlineItem*) parentItem level:(NSUInteger) level; { // update outline count outlineCount++; OutlineItem* item = [[OutlineItem alloc] init]; // Level item.level = level; // Title CGPDFStringRef title; if(CGPDFDictionaryGetString(outlineDic, "Title", &amp;title)) { const char* pchTitle = CGPDFStringGetBytePtr(title); item.title = [NSString stringWithUTF8String:pchTitle]; // DEBUG //NSLog(item.title); } if (parentItem != nil) { // Add to parent [parentItem.children addObject:item]; // Next CGPDFDictionaryRef nextDic; if (CGPDFDictionaryGetDictionary(outlineDic, "Next", &amp;nextDic)) { [self recursiveUpdateOutlines:nextDic parent:parentItem level: level]; } } // First child CGPDFDictionaryRef firstDic; if (CGPDFDictionaryGetDictionary(outlineDic, "First", &amp;firstDic)) { [self recursiveUpdateOutlines:firstDic parent:item level: level + 1]; } // Dest CGPDFStringRef destString; if(CGPDFDictionaryGetString(outlineDic, "Dest", &amp;destString)) { const char* pchDest = CGPDFStringGetBytePtr(destString); CGPDFDictionaryRef destDic; if(CGPDFDictionaryGetDictionary(dests, pchDest, &amp;destDic)) { NSLog(@""); } else { item.destString = [NSString stringWithUTF8String:pchDest]; } } else { CGPDFDictionaryRef ADic; if (CGPDFDictionaryGetDictionary(outlineDic, "A", &amp;ADic)) { const char* pchS; if (CGPDFDictionaryGetName(ADic, "S", &amp;pchS)) { CGPDFArrayRef destArray; if (CGPDFDictionaryGetArray(ADic, "D", &amp;destArray)) { int count = CGPDFArrayGetCount(destArray); switch (count) { case 5: { // dest page CGPDFDictionaryRef destPageDic; if (CGPDFArrayGetDictionary(destArray, 0, &amp;destPageDic)) { int pageNumber = [self.pages indexOfObjectIdenticalTo:destPageDic]; item.page = pageNumber; } // x CGPDFInteger x; if (CGPDFArrayGetInteger(destArray, 2, &amp;x)) { item.x = x; } // y CGPDFInteger y; if (CGPDFArrayGetInteger(destArray, 3, &amp;y)) { item.y = y; } // z } break; default: NSLog(@""); break; } } } } } return item; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
