有人知道如何获取一些结果按字母顺序排序，但忽略大小写？
Does anyone know how to fetch some results sorting them alphabetically but ignoring case?
推荐答案
谢谢您的回复，我需要排序一个简单的查询忽略大小写的结果。您的建议适用于搜索和比较。
Thank you for your reply, but I need to sort the result of a simple "query" ignoring case. Your suggestion applies for searching and comparing.
SQL，我需要一个 ORDER BY firstName ASC 必须对我的使用情况不区分大小写。
SQL speaking, I need an ORDER BY firstName ASC, and this command must be case insensitive for my usage.
我完成了一些Google搜索，我结束了阅读，我可以找到我的问题的答案。解决方案是将排序描述符的选择器设置如下：
I have done some Googling and I ended reading the NSSortDescriptor Class reference, and I could find the answer for my question. The solution is setting a selector to the sort descriptor as follow:
NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"firstName" ascending:YES selector:@selector(caseInsensitiveCompare:)];
我希望它对更多的人有用。
