UIMenuController

实现代码如下：

 

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. }
