How To Use

create a subClass of UIViewController

import "UIViewController+YVTopBarController.h"

set viewControllers

- (void)addControllers{
    NSMutableArray *viewControllers = [NSMutableArray array];
    NSMutableArray *array = [NSMutableArray arrayWithObjects:[UIColor redColor],[UIColor greenColor],[UIColor yellowColor], nil];
    for (NSInteger i=0; i<array.count; i++) {
        UIViewController *viewController = [UIViewController new];
        viewController.title = [NSString stringWithFormat:@"页面%ld",(long)i];
        viewController.view.backgroundColor = array[i];
        [viewControllers addObject:viewController];
    }
    self.viewControllers = viewControllers;
}

Attentions:

1.topBarItem's text equals to childViewController's title.if childViewController's title is nil,defaultTopBarItem's text is nil

2.childViewController's view layout should include topBar's frame.

Change ViewController Event

implemente method

- (void)didScrollToIndex:(NSInteger)index    

Custom Your TopBarItem

implement YVTopBarDataSource

//topBar高度
- (CGFloat)heightForTopBar:(YVTopBar *)topBar;

//每个item的size
- (CGSize)topBar:(YVTopBar *)topBar SizeForIndex:(NSInteger)index;

//间隔
- (CGFloat)sepeWidthForTopBar:(YVTopBar *)topBar;

/*
***自定义item必须实现下面两个方法
*/

//自定义item的类名，方便collectionView注册
- (NSString *)reUsableItemClassNameForTopBar:(YVTopBar *)topBar;

//对reUsableItem填充数据、设置样式...
- (YVTopBarItem *)topBar:(YVTopBar *)topBar ReUsableItem:(YVTopBarItem *)reUsableItem TitleItemForIndex:(NSInteger)index;
