我有一个表视图，可以搜索标题。我想在单元格中添加字幕，我知道该怎么做，但我希望能够通过字幕和标题搜索信息。字幕数组中每个项目的索引对应于标题数组中相同索引处的对象。所以，我遇到的一个问题是，当我根据搜索文本搜索并查看表格自动更新时，我需要使用正确的字幕显示。如果我搜索副标题中的文本，则需要执行相同的操作。它需要显示副标题的正确标题。有什么建议吗？
这是我的代码：
#import "List.h"
#import "RSFM.h"
#import "DTCustomColoredAccessory.h"
@interface List ()
@end
@implementation List

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。
以下是我创建字典的方法。
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];
以下是我尝试设置单元格标题和副标题的方法。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"];
以下是日志中的错误。

答案 0 :(得分：1)
您应该创建一个字典数组，而不是拥有两个数组。
搜索标题时，您会找到匹配项，您应该将该字典放入结果数组中。现在使用字典数组，您可以检索与标题相关联的字幕。
您还可以使用cellForRowAtIndexPath方法进行以下更改：
cell.textLabel.text = [displayItems objectAtIndex:indexPath.row];
int currentIndex = [title indexOfObject:cell.textLabel.text];
cell.detailTextLabel.text = [subtitle objectAtIndex:currentIndex];
答案 1 :(得分：1)
我建议将标题和副标题存储在一起而不是单独的数组。您可以使用带有@“title”和@“subtitle”键的字典数组，或使用这些属性创建自定义模型对象。
无论哪种方式，您所要做的就是将您使用的相同逻辑与标题字符串应用于相应的字幕字符串。在不更改数据结构的情况下，您可以将searchBar:textDidChange:逻辑更新为：
for (NSUInteger i = 0; i < [title count]; i++ )
{
if ( ([[title objectAtIndex:i rangeOfString:searchText options:NSCaseInsensitiveSearch] != NSNotFound) || ([[subtitle objectAtIndex:i rangeOfString:searchText options:NSCaseInsensitiveSearch] != NSNotFound) ) {
[displayItems addObject:string];
}
}
这种方式searchText可以是标题字符串或字幕字符串。
注意：我没有查看文档或使用Xcode的自动完成功能就输入了这个内容，因此可能会出现拼写错误，拼写错误或语法错误。
更新：
根据编辑中的信息，我认为您的farmMarkets数组的结构是错误的。你想要的是让farmMarkets数组包含每个市场的NSDictionary。然后每个单独的字典都有@“title”和@“subtitle”键。为了使这更容易可视化，您可能需要像这样初始化farmMarkets：
NSArray *farmMarkets = @[
@{@"title" : @"Cates Farm",
@"subtitle" : @"Hwy 425 Henderson, KY 42420"},
@{@"title" : @"Broadbent B & B Foods",
@"subtitle" : @"257 Mary Blue Road Kuttawa, KY 42055"},
@{@"title" : @"Cayce's Pumpkin Patch",
@"subtitle" : @"153 Farmersville Road Princeton, KY 42445"}
];
（仅供参考，正如@“asdf”将创建一个NSString，@ [list，of，objects]将创建一个NSArray，@ {key：value，key：value}将创建一个NSDictionary。）
然后，您可以执行此操作以获取您的单元格的信息：
cell.textLabel.text = [[displayItems objectAtIndex:indexPath.row] objectForKey:@"title"];
cell.detailTextLabel.text = [[displayItems objectAtIndex:indexPath.row] objectForKey:@"subtitle"];
