我需要比较2个字符串，只查看第一个字母。

I need to compare 2 strings, looking at the first letter only.

有一种方法来比较A和Á，并将其识别为A， '？

Is there a method to compare A to Á, and recognize it as A, without the ´?

NSString

NSString has a diacritic-insensitive comparison mode which will do what you're after.

// should return NSOrderedSame, i.e. identical
[@"Apple" compare:@"Ápple"
          options:NSDiacriticInsensitiveSearch]

$ b b

如果你也希望它不区分大小写：

If you want it to be case-insensitive as well:

// ditto
[@"APPLE" compare:@"Ápple"
          options:NSDiacriticInsensitiveSearch | NSCaseInsensitiveSearch]
