Here is my current NSPredicate:
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"UPC==%@ OR ItemID==%@", aUPCCode,aUPCCode];
How can I make this case insensitive?
And I do not want to do any partial matching.
Example if they enter 123 for aUPCCode I do not want to get 123, 123a, 123b, 123c, ect. I would only want an exact match.
I thought about doing this but it seems a little ridiculous:
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"UPC==%@ OR ItemID==%@ OR UPC==%@ OR ItemID==%@ OR UPC==%@ OR ItemID==%@", aUPCCode,aUPCCode,[ aUPCCode lowercaseString] ,[aUPCCode lowercaseString], [aUPCCode uppercaseString],[aUPCCode uppercaseString]];
This answer is from 2011, if you are using Swift check Harjot Singh's answer.
As Dave DeLong said, you can use:
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"UPC ==[c] %@ OR ItemID ==[c] %@", aUPCCode,aUPCCode];
Edit:
Use ==[c] instead of ==[cd] or you get accents too (abcd == àbcd).
