需要在VFR阅读器中列出搜索功能

Question

I have implemented Pdf reading library from this tutorial: . It's based on VFR Reader .

Now I want to add List search results functionality. If you have some idea about FastPdfKit it's provided List search functionality.

I want same search functionality as attached image.

If any body had implemented same search functionality in VFR Reader than I will really appreciate your help.

Thanks in advance

You can use following method to find words from pdf. It may help you.

-(BOOL)page:(CGPDFPageRef)inPage containsString:(NSString *)inSearchString;
{
[self setCurrentData:[NSMutableString string]];
CGPDFContentStreamRef contentStream = CGPDFContentStreamCreateWithPage(inPage);
CGPDFScannerRef scanner = CGPDFScannerCreate(contentStream, table, self);
bool ret = CGPDFScannerScan(scanner);
CGPDFScannerRelease(scanner);
CGPDFContentStreamRelease(contentStream);
 NSLog(@"%@",[currentData uppercaseString]);
 NSLog(@"%d",[[currentData uppercaseString]rangeOfString:[inSearchString uppercaseString]].location != NSNotFound);
return ([[currentData uppercaseString]rangeOfString:[inSearchString uppercaseString]].location != NSNotFound);
}
