用于uicollectionview的IOS字母滚动 [英] IOS alphabetical scroll for uicollectionview

问题描述

我有一个收集视图，显示了人们及其名字的多个图像，我已经实现了搜索和排序功能，但问题是我也想按字母顺序排列。但是它的collectionview没有像table这样的委托方法。

I had a collectionview which shows multiple images of peoples and their names , i had implemented search and sorting functionality , but problem is i want alphabetical also . but it collectionview does not have delegate methods like table has .

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
    return[NSArray arrayWithObjects:@"a", @"e", @"i", @"m", @"p", nil];
}

- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString
    *)title atIndex:(NSInteger)index {
        return <yourSectionIndexForTheSectionForSectionIndexTitle >;
}

我试过这个问题也是，但这显示了一个部分中的collectionview单元格。但问题是我不想要多个部分。我只想要部分和实现字母滚动功能，请指导我一些帮助

i had tried this question also , but this shows collectionview cells in a section. but problem is i dont want multiple sections. i want only section and implement alphabetical scroll functionality it , please guide me some help

上面的方法不在collectionviewdelegate方法中。

above methods are not in collectionviewdelegate methods.

推荐答案

BDKCollectionIndexView 实现 UITableView -like部分索引栏。一旦将它放在屏幕上，它就很容易集成：只需从数据源中分配一个 NSString 的数组：

BDKCollectionIndexView implements a UITableView-like section index bar. It's pretty easy to integrate once you have it positioned onscreen: just assign an array of NSStrings from your datasource:

self.indexView.indexTitles = self.fetchResultsController.sectionIndexTitles;
