实现代码如下：
01.-(IBAction)panGestureTop:(UILongPressGestureRecognizer *)longPress02.{03. 04.UIMenuItem * itemPase = [[UIMenuItem alloc] initWithTitle:@"复制" action:@selector(copyimage)];05.UIMenuItem * itemTrans = [[UIMenuItem alloc] initWithTitle:@"转发" action:@selector(trans)];06.UIMenuItem * itemCollect = [[UIMenuItem alloc] initWithTitle:@"收藏" action:@selector(collect)];07.UIMenuItem * itemJoin = [[UIMenuItem alloc] initWithTitle:@"加入" action:@selector(join)];08. 09.UIMenuController * menuController = [UIMenuController sharedMenuController];10.[menuController setMenuItems: @[itemPase,itemCollect,itemTrans,itemJoin]];11. 12.CGPoint location = [longPress locationInView:[longPress view]];13.CGRect menuLocation = CGRectMake(location.x, location.y, 0, 0);14.[menuController setTargetRect:menuLocation inView:[longPress view]];15.menuController.arrowDirection = UIMenuControllerArrowDown;16. 17.[menuController setMenuVisible:YES animated:YES];18. 19.}20.-(BOOL)canBecomeFirstResponder21.{22.return YES;23.}24. 25.-(void)copyimage26.{27. 28.UIPasteboard * pasterBoard = [UIPasteboard pasteboardWithName:@"com.test.image" create:YES];29.pasterBoard.image = [self.topImgView image];30. 31.}32.-(IBAction)panGestureBottom:(UILongPressGestureRecognizer *)longPress33.{34.UIMenuItem * itemPase = [[UIMenuItem alloc] initWithTitle:@"粘贴" action:@selector(pase)];35. 36.UIMenuController * menuController = [UIMenuController sharedMenuController];37.[menuController setMenuItems: @[itemPase]];38. 39.CGPoint location = [longPress locationInView:[longPress view]];40.CGRect menuLocation = CGRectMake(location.x, location.y, 0, 0);41.[menuController setTargetRect:menuLocation inView:[longPress view]];42.menuController.arrowDirection = UIMenuControllerArrowDown;43. 44.[menuController setMenuVisible:YES animated:YES];45. 46.}47.-(void)pase48.{49.UIPasteboard * pasterBoard = [UIPasteboard pasteboardWithName:@"com.test.image" create:NO];50.self.bottomImgView.image = pasterBoard.image;51. 52.}
