如何对一个数组中的NSDictionaries执行无大小写和无音调的过滤(而不是NSString)?
原标题:How to perform a case and diacritic insensitive filter of an array of NSDictionaries (not NSString)?

我有一个字典数组。我想过滤这个数组,看看每个字典的@"name"字段是否包含一个给定的字符串。

重点是我希望我的过滤对大小写和音标不敏感。

如果数组只包含字符串,我可以很容易地使用NSPredicate。然而,它并不是这样,我也看不出NSPredicate如何适应这种情况。

如果我只关心不区分大小写,我可以遍历所有项,并将小写过的过滤字符串与小写的名称进行比较。但我不知道类似于变音符的技巧。

这个问题有一个好的解决方案吗?

最佳回答

请查看此问题的最佳答案:

UITableView的部分标题中的非美国字符

您应该能够使用该代码来去除音标,并进行不区分大小写的比较或搜索。

关于像这样的东西怎么样?

NSArray * array = .....
NSString * searchString = @"foo";
NSArray * filteredArray = [array filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"name contains[cd] %@", searchString]];
