it can create a new class derive from PDFDoc class.
you need to override methods:

Code:

-(int)pageCount;
-(PDFPage *)page:(int) pageno;
-(float)pageWidth:(int) pageno;
-(float)pageHeight:(int) pageno;
-(NSString *)pageLabel:(int)pageno;
-(bool)newRootOutline: (NSString *)label :(int) pageno :(float) top;
-(PDFPage *)newPage:(int) pageno :(float) w :(float) h;
-(bool)movePage:(int)pageno1 :(int)pageno2;

rhe second solution shall be:
create a new PDF file and import pages you needed.

you must have premium license, and create PDF file in sandbox, which has write access right.
and then objc codes like:

Code:

PDFDoc *doc_src;
PDFDoc *doc_dst;
doc_src = [[PDFDoc alloc] init];
doc_dst = [[PDFDoc alloc] init];
[doc_src open:@"source path to extists pdf file"];
[doc_dst open:@"dest path to creating pdf file"];
PDFImportCtx *ctx = [doc_src newImportCtx];
int pgno = page_range_start;
int pgend = page_range_end;
int pgdst = 0;
wile(pgno < pgend)
{
  [ctx import :pgno :pgdst];
  pgno++;
  pgdst++;
}
[doc_dst save];
ctx = nil;
doc_src = nil;
doc_dst = nil;
