Question

i have 2 string objects containing same string but case is different,now i wanna compare them ignoring the case sensitivity,how to do that??here is the code...

Answer 1

A simple one, convert both strings in same case.Here i'm converting it to lower case and then checking it.

if ([[myString1 lowercaseString] [myString2 lowercaseString]])
{
 // same
}
