UIMenuController

实现代码如下：

view sourceprint?

01.-(IBAction)panGestureTop:(UILongPressGestureRecognizer *)longPress

02.{

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)canBecomeFirstResponder

21.{

22.return YES;

23.}

24. 

25.-(void)copyimage

26.{

27. 

28.UIPasteboard * pasterBoard = [UIPasteboard pasteboardWithName:@"com.test.image" create:YES];

29.pasterBoard.image = [self.topImgView image];

30. 

31.}

32.-(IBAction)panGestureBottom:(UILongPressGestureRecognizer *)longPress

33.{

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)pase

48.{

49.UIPasteboard * pasterBoard = [UIPasteboard pasteboardWithName:@"com.test.image" create:NO];

50.self.bottomImgView.image = pasterBoard.image;

51. 

52.}
