需要两个文件 KxMenu.h KxMenu.m

用的时候在需要的文件里添加两个方法就行了。。

_btn4 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    _btn4.frame = CGRectMake(W - 105, H - 55, 100, 50);
    [_btn4 setTitle:@"Click me" forState:UIControlStateNormal];
    [_btn4 addTarget:self action:@selector(showMenu:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:_btn4];

- (void)showMenu:(UIButton *)sender
{
    NSArray *menuItems =
    @[

      [KxMenuItem menuItem:@"ACTION MENU"
                     image:nil
                    target:nil
                    action:NULL],

      [KxMenuItem menuItem:@"Share this"
                     image:[UIImage imageNamed:@"action_icon"]
                    target:self
                    action:@selector(pushMenuItem:)],

      [KxMenuItem menuItem:@"Check menu"
                     image:[UIImage imageNamed:@"check_icon"]
                    target:self
                    action:@selector(pushMenuItem:)],

      [KxMenuItem menuItem:@"Reload page"
                     image:[UIImage imageNamed:@"reload"]
                    target:self
                    action:@selector(pushMenuItem:)],

      [KxMenuItem menuItem:@"Search"
                     image:[UIImage imageNamed:@"search_icon"]
                    target:self
                    action:@selector(pushMenuItem:)],

      [KxMenuItem menuItem:@"Go home"
                     image:[UIImage imageNamed:@"home_icon"]
                    target:self
                    action:@selector(pushMenuItem:)],
      ];

    KxMenuItem *first = menuItems[0];
    first.foreColor = [UIColor colorWithRed:47/255.0f green:112/255.0f blue:225/255.0f alpha:1.0];
    first.alignment = NSTextAlignmentCenter;

    [KxMenu showMenuInView:self.view
                  fromRect:sender.frame
                 menuItems:menuItems];
}

- (void) pushMenuItem:(id)sender
{
    NSLog(@"%@", sender);
}
