我有一个表格视图，可以搜索标题。我想为单元格添加字幕，我知道该怎么做，但我希望能够通过字幕中的信息以及标题进行搜索。subtitles 数组中每一项的索引，对应于 title 数组中相同索引处的对象。所以，我遇到的一个问题是，当我搜索并且表格视图根据搜索文本自动更新时，我需要显示正确的字幕。如果我搜索字幕中的文本，也需要做同样的事情。它需要显示正确的字幕标题。有什么建议么？
这是我的代码：
#import "List.h"
#import "RSFM.h"
#import "DTCustomColoredAccessory.h"
@interface List ()
@end
@implementation List
{
NSMutableArray *title;
NSMutableArray *subtitle;
NSMutableArray *displayItems;

// Custom initialization

return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];

编辑：我现在正在尝试使用带有标题和副标题键的字典，但是当我打开此视图时应用程序崩溃了。
这是我创建字典的方式。
keys = [NSArray arrayWithObjects:@"titleKey", @"subtitleKey", nil];
objects = [[NSMutableArray alloc]init];
[objects addObject:title];
[objects addObject:subtitle];
marketDictionary = [[NSMutableDictionary alloc]init];
marketDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys];
farmMarkets = [[NSMutableArray alloc]initWithObjects:marketDictionary, nil];
displayItems = [[NSMutableArray alloc]initWithArray:farmMarkets];
这是我尝试设置单元格标题和字幕的方式。该应用程序在第一行崩溃。
cell.textLabel.text = [[displayItems objectAtIndex:indexPath.row]objectForKey:@"titleKey"];
cell.detailTextLabel.text = [[displayItems objectAtIndex:indexPath.row]objectForKey:@"subtitleKey"];
这是日志中的错误。
