NSString has a cunningly named lowercaseString method.

NSString *noCaps = [yourString lowercaseString];

Edited to add

If you are asking how to change the actual string to be lowercase - you can't. NSStrings are immutable. They can't be changed after they have been created. If you want to change the string in place you should use an NSMutableString like so:

[aMutableString setString:[aMutableString lowercaseString]];
