ios - 适用于 iOS 7 的 localizedCaseInsensitiveContainsString

Question

我如何为 iOS 7 使用 localizedCaseInsensitiveContainsString？

因为 ragneOfString 方法没有给我预期的结果。但是 localizedCaseInsensitiveContainsString 方法给了我想要的结果。

并且 localizedCaseInsensitiveContainsString 在 iOS7 中不可用。我试过了，但它没有给我想要的结果

 if([session.sessiontitle rangeOfString:searchtext options:NSCaseInsensitiveSearch].location!=NSNotFound 
               || [session.roomname rangeOfString:searchtext options:NSCaseInsensitiveSearch].location!=NSNotFound
               || [session.speakername rangeOfString:searchtext options:NSCaseInsensitiveSearch].location!=NSNotFound
               || [session.speakerprofile rangeOfString:searchtext options:NSCaseInsensitiveSearch].location!=NSNotFound)
            {
                [sessionArray addObject:session];
            }

提前致谢!

您需要使用本地化方法。

[session.sessiontitle rangeOfString:searchtext options: NSCaseInsensitiveSearch range:NSMakeRange(0, session.sessiontitle.length) locale:[NSLocale currentLocale]].location!=NSNotFound

更新:
这有效:
NSArray *allNames=@[@"does jenny work",@"JENNy works",@"works with JEnny",@"jack",@"ram",@"jhon"];
NSMutableArray *results=[NSMutableArray new];
for (NSString *name in allNames) {
if ([name rangeOfString:@"jenny" options:NSCaseInsensitiveSearch range:NSMakeRange(0, name.length) locale:[NSLocale currentLocale]].location!=NSNotFound) {
[results addObject:name];
}
}
NSLog(@"results :>%@<",results);<br/>
results :>(
"does jenny work",
"JENNy works",
"works with JEnny"
)<
