iOS_第3方类库_侧滑选项卡SlideSwitchView
最终效果:
使用方法:
1、在主控制器中创建一个【SlideSwitchView】的对象实例,并用成员变量记住,如_slideSwitchView,并添加到self.view
2、设置【_slideSwitchView】的4个属性:
tabItemNormalColor:选项卡正常时的颜色
tabItemSelectedColor:选项卡选中时的颜色
shadowImage:盖在选项卡上面的一张图片
slideSwitchViewDelegate:设置代理为当前控制器,用于监听滑动时,切换控制器
3、调用【_slideSwitchView】的buildUI方法
4、遵守协议,并实现代理方法;如:
顶部选项卡的个数
每个选项卡对应的控制器
