}用JXPagerView管理的区别：
1、注册协议JXPagerViewDelegate、舍弃协议JXCategoryListContainerViewDelegate
1.1、舍弃 : - (NSInteger)numberOfListsInlistContainerView:(JXCategoryListContainerView *)listContainerView;
1.2、舍弃： - (id<JXCategoryListContentViewDelegate>)listContainerView:(JXCategoryListContainerView *)listContainerView initListForIndex:(NSInteger)index;
1.3、舍弃： - (void)categoryView:(JXCategoryBaseView *)categoryView didClickSelectedItemAtIndex:(NSInteger)index ;
1.4、舍弃： - (void)categoryView:(JXCategoryBaseView *)categoryView didSelectedItemAtIndex:(NSInteger)index ;
1.5、舍弃： - (void)categoryView:(JXCategoryBaseView *)categoryView didScrollSelectedItemAtIndex:(NSInteger)index;
1.6、舍弃： - (void)categoryView:(JXCategoryBaseView *)categoryView
scrollingFromLeftIndex:(NSInteger)leftIndex
toRightIndex:(NSInteger)rightIndex
ratio:(CGFloat)ratio ;
2、舍弃属性类 JXCategoryListContainerView
2.1、舍弃 @property(nonatomic,strong)JXCategoryListContainerView *listContainerView;/// 此属性决定依附于此的viewController@property(nonatomic,strong)
2.1 、舍弃
-(JXCategoryListContainerView *)listContainerView{
if (!_listContainerView) {
_listContainerView = [JXCategoryListContainerView.alloc initWithType:JXCategoryListContainerType_CollectionView
delegate:self];
_listContainerView.defaultSelectedIndex = 1;// 默认从第二个开始显示
[self.view addSubview:_listContainerView];
[_listContainerView mas_makeConstraints:^(MASConstraintMaker *make) {
// make.edges.equalTo(self.view);
make.top.equalTo(self.topLineLab.mas_bottom).offset(listContainerViewDefaultOffset);
make.left.right.bottom.equalTo(self.view);
}];
[self.view layoutIfNeeded];
// /// ❤️在需要的地方写❤️
// NSNumber *currentIndex = [self.listContainerView valueForKey:@"currentIndex"];
// NSLog(@"滑动或者点击以后，改变控制器，得到的目前最新的index = %d",currentIndex.intValue);
}return _listContainerView;
}
3、JXCategoryTitleView 舍弃部分属性：
3.1、舍弃：_categoryView.contentScrollView = self.listContainerView.scrollView;/// 关联cotentScrollView，关联之后才可以互相联动！！！
3.2、在 JXPagerView 模式下 ,不用设置JXCategoryTitleView的height、size、frame。而是在JXPagingViewDelegate代理方法里面设置
4、_categoryView新增属性：_categoryView.listContainer = (id<JXCategoryViewListContainer>)self.pagerView.listContainerView;
5、全局新增属性：@property(nonatomic,strong)JXPagerView *pagerView;
6、新增JXPagingViewDelegate代理协议的实现
6.1、- (UIView *)tableHeaderViewInPagerView:(JXPagerView *)pagerView;
6.2、- (void)pagerView:(JXPagerView *)pagerView
mainTableViewDidScroll:(UIScrollView *)scrollView;
6.3、- (NSUInteger)tableHeaderViewHeightInPagerView:(JXPagerView *)pagerView ;
6.4、- (NSUInteger)heightForPinSectionHeaderInPagerView:(JXPagerView *)pagerView;/// JXCategoryTitleView *categoryView 的高度
6.5、- (UIView *)viewForPinSectionHeaderInPagerView:(JXPagerView *)pagerView;
6.6、- (NSInteger)numberOfListsInPagerView:(JXPagerView *)pagerView;
6.7、- (id<JXPagerViewListViewDelegate>)pagerView:(JXPagerView *)pagerView
initListAtIndex:(NSInteger)index;
7、各个子VC要遵循代理协议JXPagerViewListViewDelegate，并实现相关方法
7.1、 - (UIView *)listView;
7.2、 - (UIScrollView *)listScrollView;
7.3、 - (void)listViewDidScrollCallback:(void (^)(UIScrollView *scrollView))callback;
7.4、或者直接导入类：#import "UIViewController+JXPagerViewListViewDelegate.h"
