Векторизация для рутины с использованием numpy.roll

Это довольно просто:

  #import <MobileCoreServices/UTCoreTypes.h>

  NSMutableDictionary *item = [[NSMutableDictionary alloc] init];

  NSData *rtf = [attributedString dataFromRange:NSMakeRange(0, attributedString.length)
                             documentAttributes:@{NSDocumentTypeDocumentAttribute: NSRTFDTextDocumentType}
                                          error:nil];

  if (rtf) {
    [item setObject:rtf forKey:(id)kUTTypeFlatRTFD];
  }

  [item setObject:attributedString.string forKey:(id)kUTTypeUTF8PlainText];

  UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
  pasteboard.items = @[item];
