ios - 排序 NSArray 的 NSDictionaries 忽略大小写

Question

我正在使用以下代码对 NSDictionaries 的 NSArray 进行排序

NSArray *getIndexArray = [nicknamesCombinedArray copy];

            NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"MANUFACTURER"  ascending:YES];
            NSDictionary *sortedGetIndexArray = [getIndexArray sortedArrayUsingDescriptors:[NSArray arrayWithObjects:descriptor,nil]];

唯一的问题是，当它排序时，如果单词全部大写，那么它会像这样排序

JESS
Jack
Jelly
Job

我想要的地方

Jack
Jelly
JESS
Job
