search text in pdf in iphone

Question

I am trying to do search functionality in iPhone. I pass the page number and the string to be searched.. but it is not getting the proper output. in contentStream I get nothing. I got this code by googling. I don't know what will be there in contentStream object.

-(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);
return ([[currentData uppercaseString] 
         rangeOfString:[inSearchString uppercaseString]].location != NSNotFound);

}

If there is any other solution then also it is fine.
