How to compare A and Á on iPhone

Question

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

Is there a way to compare A with Á and recognize it as A without ´?

Answer 1

NSString has a diacritically sensitive comparison mode that will do what you need.

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

If you want it to be case insensitive:

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