ZXSegmentMenu View

效果图

等宽	自然宽度	滚动
menuCountAtOnePage = 2	menuCountAtOnePage = 0	menuCountAtOnePage = 0

Test

_segMenu = [[ZXSegmentMenu alloc] initWithFrame:frame menuHeight:40 menuCountAtOnePage:0 parentController:self];
_segMenu.delegate = self;
_segMenu.datasource = self;
[self.view addSubview:_segMenu];

• frame : 如果等于屏幕尺寸(UIScreen.mainScreen.bounds)，会自动减去Tabbar和NavBar高度
• menuHeight: 菜单高度
• menuCountAtOnePage ：大于0 时，菜单宽 = size / mCount 。等于0时 菜单宽 = 自然宽度
• parentController ：用于addChildViewController

ZXSegmentMenuDataSource

@required
- (NSInteger)numberOfCountInSegmentMenu:(ZXSegmentMenu *)menu;
- (NSString *)zxSegmentMenu:(ZXSegmentMenu *)menu titleFowIndex:(NSInteger)index;
- (UIView *)zxSegmentMenu:(ZXSegmentMenu *)menu viewAtIndex:(NSInteger)index;

@optional
//是否有红点
- (BOOL)zxSegmentMenu:(ZXSegmentMenu *)menu showDotAtIndex:(NSInteger)index;
//未读消息
- (NSInteger)zxSegmentMenu:(ZXSegmentMenu *)menu unreadMsgCountAtIndex:(NSInteger)index;

ZXSegmentMenuDelegate

- (void)zxSegmentMenu:(ZXSegmentMenu *)menu selectedAtIndex:(NSInteger)index;

关于样式

样式可在 ZXSegMenuCell 中修改

定义太多样式的意义不大，每个人需求不一样。 这里只是给个思路吧，有很多东西可以完善。比如，重用、自动布局。
