ALOptionsButton

用于在UITabbar中间添加一个可弹出菜单的button。

示例

用法

//初始化并添加到tabbar中间
ALOptionsButton *button = [[ALOptionsButton alloc] initForTabBar:self.tabBar forItemIndex:2 delegate:self];
button.backgroundColor = [UIColor redColor];

#ALOptionsButtonDelegate

弹出菜单中的按钮数量，推荐3-4个

- (NSUInteger)alOptionsButtonNumberOfItems:(ALOptionsButton *)alOptionsButton;

返回菜单项，类似于cellforRowAtIndexPath

- (ALOptionsItem *)tabBar:(UITabBar *)tabBar itemAtIndex:(NSUInteger)index;

点击菜单项的回调

- (void)alOptionsButton:(ALOptionsButton *)alOptionsButton didSlectItem:(ALOptionsItem *)item;
