自定义UIMenuController（以UITabelViewCell为实例）

UIMenuController使用要点：

1. Menu所处的View必须实现 – (BOOL)canBecomeFirstResponder, 且返回YES

2. Menu所处的View必须实现 – (BOOL)canPerformAction:withSender,并根据需求返回YES或NO

3. 使Menu所处的View成为First Responder (becomeFirstResponder)

4. 实现UIMenuItem相应的使用方法

5. 定位Menu (- setTargetRect:inView:)

6. 展示Menu (- setMenuVisible:animated:)

首先给需要显示UIMenuController的对象（这里是cell）添加了长按事件，在初始化方法中添加即可。若对象本身长按时存在系统的UIMenuController（如UITextFiled\ UITextView\ UIWebView），即本身含有长按方法，那么只需在初始化方法中添加需要的UIMenuItem即可，无需添加长按方法。

UILongPressGestureRecognizer *recognizer = [[UILongPressGestureRecognizeralloc]initWithTarget:selfaction:@selector(longPress:)];

    [cell addGestureRecognizer:recognizer];

好，事件加上了，剩下的点击就是实现自定义剪贴板了，上代码：

- (void)longPress:(UILongPressGestureRecognizer *)recognizer{

       if (recognizer.state ==UIGestureRecognizerStateBegan) {

             CopyCell *cell = (CopyCell *)recognizer.view;

             [cell becomeFirstResponder];

            UIMenuItem *item1 = [[UIMenuItemalloc]initWithTitle:@"Flag"action:@selector(one:)];

            UIMenuItem *item2 = [[UIMenuItemalloc]initWithTitle:@"Approve"action:@selector(two:)];

            UIMenuItem *item3 = [[UIMenuItemalloc]initWithTitle:@"Deny"action:@selector(three:)];

            UIMenuController *menu = [UIMenuControllersharedMenuController];

            [menu setMenuItems:[NSArrayarrayWithObjects:item1,item2, item3, nil]];

            [menusetTargetRect:cell.frame  inView:cell];

            [menu setMenuVisible:YESanimated:YES];

      }

}

- (BOOL)canBecomeFirstResponder{

    returnYES;

}

下面就是你所要使用的方法了

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender{

    if(action ==@selector(one:)){

        return  YES;

    }

    else if(action == @selector(two:)){

        return  YES;

    }

    else if(action == @selector(three:)){

        return  YES;

    }

    else return NO；

}

- (void)one:(id)sender {

  //  method

}

- (void)two:(id)sender {

  //  method

}

- (void)three:(id)sender {

  //  method

}
