Case insensitive comparison NSString

Question

Can anyone point me to any resources about case insensitive comparison in Objective C? It doesn\'t seem to have an equivalent method to str1.equalsIgnoreCase(str2)

Answer 1

You could always ensure they're in the same case before the comparison:

if ([[stringX uppercaseString] isEqualToString:[stringY uppercaseString]]) {
    // They're equal
}

The main benefit being you avoid the potential issue described by matm regarding comparing nil strings. You could either check the string isn't nil before doing one of the compare:options: methods, or you could be lazy (like me) and ignore the added cost of creating a new string for each comparison (which is minimal if you're only doing one or two comparisons).
