关于如何展示多栏目多个条目多个cell多个collectioncell的展示类似下面这种情况

像这种比较复杂的样式，里面涵盖了SegmentTitleView UITableView UICollectionView 这几种类型，基本的层级关系是
SegmentTitleView 包含 SegmentTitleView 包含 UITableView
包含 UICollectionView 这样的样式
关于SegmentTitleView的使用可以直接参考 iOS自定义一个仿网易左右滑动切换页面框架
///默认选择
@property (nonatomic,assign) NSInteger defaultSelect;
@property (nonatomic, strong) FSSegmentTitleView *titleView;
///当前控制器
@property (nonatomic ,strong) UIViewController *currentVC;
@property (nonatomic, strong) NSMutableArray<UIViewController *> *childVCs;
self.titles = @[@"全部基金",@"自选基金"];
self.titleView = [[FSSegmentTitleView alloc]initWithFrame:CGRectMake(0, 0, self.titles.count*100, 40) titles:self.titles delegate:self indicatorType:FSIndicatorTypeNone];
self.titleView.indicatorExtension = 6;
self.titleView.selectIndex = _defaultSelect;
self.titleView.titleFont = [UIFont systemFontOfSize:15];
self.titleView.titleSelectFont = [UIFont boldSystemFontOfSize:15];
self.titleView.titleNormalColor = RGBCOLOR(253, 149, 137);
self.titleView.titleSelectColor = [UIColor whiteColor];
self.navigationItem.titleView = self.titleView;
// 切换各个标签内容
- (void)replaceController:(UIViewController *)oldController newController:(UIViewController *)newController
{
/**
* 着重介绍一下它
* transitionFromViewController:toViewController:duration:options:animations:completion:
* fromViewController 当前显示在父视图控制器中的子视图控制器
* toViewController 将要显示的姿势图控制器
* duration 动画时间(这个属性,old friend 了 O(∩_∩)O)
* options 动画效果(渐变,从下往上等等,具体查看API)
* animations 转换过程中得动画
* completion 转换完成
*/
[self.view addSubview:newController.view];
[newController.view mas_makeConstraints:^(MASConstraintMaker *make) {
make.edges.equalTo(self.view);
}];
[self addChildViewController:newController];
if (![[UIApplication sharedApplication] isIgnoringInteractionEvents]) {
[[UIApplication sharedApplication] beginIgnoringInteractionEvents];
}
[self transitionFromViewController:oldController toViewController:newController duration:0.2 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
} completion:^(BOOL finished) {
if (finished) {
[newController didMoveToParentViewController:self];
[oldController willMoveToParentViewController:nil];
[oldController removeFromParentViewController];
self.currentVC = newController;
}else{
self.currentVC = oldController;
}
if ([[UIApplication sharedApplication] isIgnoringInteractionEvents]){
[[UIApplication sharedApplication] endIgnoringInteractionEvents];
}
}];
}
#pragma mark FSSegmentTitleViewDelegate
- (void)FSSegmentTitleView:(FSSegmentTitleView *)titleView startIndex:(NSInteger)startIndex endIndex:(NSInteger)endIndex
{
// childVC里放置的是对应的那些子页面的VC
UIViewController *newVC = self.childVCs[endIndex];
[self replaceController:self.currentVC newController:newVC];
}
这就是第一层的titleVC的基本展示了，接下来第二层titleview的配置也参照第一层，但是要相应的改变titles的数量。这里就不过多赘述了
