Split PDF pages on iOS

To split a PDF document into multiple pages.

Obj-C

PTPDFDoc *doc = [[PTPDFDoc alloc] initWithFilepath: filename];
int page_num = [doc GetPageCount];
for (int i=1; i<=page_num; ++i)
{
  PTPDFDoc *new_doc = [[PTPDFDoc alloc] init];
  [new_doc InsertPages: 0 src_doc: doc start_page: i end_page: i flag: e_ptinsert_none];
  [new_doc SaveToFile: [output_filename stringByAppendingFormat: @"_split_page_%d.pdf", i] flags: e_ptlinearized];
}

Swift

let doc: PTPDFDoc = PTPDFDoc(filepath: filename)

let page_num = doc.getPageCount()
for i in 1..page_num
{
  let new_doc: PTPDFDoc = PTPDFDoc()
  let output_file: String = "\(output_filename)_split_page_\(i).pdf"
  new_doc.insertPages(0, src_doc: doc, start_page: i, end_page: i, flag: e_ptinsert_none)
  new_doc.save(toFile: output_file, flags: e_ptlinearized.rawValue)
}
