New methods of NSString in iOS6

NSString *string = @"hello, this is Andy yi!";

    

NSString *upperString = [string uppercaseStringWithLocale:[NSLocale currentLocale]];

NSLog(@"upperStr: %@", upperString);

    

NSString *capString = [upperString capitalizedStringWithLocale:[NSLocale currentLocale]];

NSLog(@"capStr: %@", capString);

    

NSString *lowerString = [capString lowercaseStringWithLocale:[NSLocale currentLocale]];

NSLog(@"lowerStr: %@", lowerString);

This is the result:
