Objective-C如何为每个段索引创建字典以及如何在UITableview中显示所选索引的字典值

NSMutableDictionary *indexDictionary = [NSMutableDictionary dictionary];

[indexDictionary setObject:@"ValueA" forKey:@"A"];
[indexDictionary setObject:@"ValueB" forKey:@"B"];
[indexDictionary setObject:@"ValueC" forKey:@"C"];

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"CellIdentifier" forIndexPath:indexPath];
    
    // 获取段索引
    NSString *sectionIndex = [indexDictionary allKeys][indexPath.section];
    
    // 获取对应的字典值
    NSString *dictionaryValue = [indexDictionary objectForKey:sectionIndex];
    
    // 在UITableViewCell中显示字典值
    cell.textLabel.text = dictionaryValue;
    
    return cell;
}
