Instead of trying to force the keyboard into lower-case, just force the characters to lower-case after the user types them.

You didn't say whether you're using a UITextField or a UITextView. Let's suppose you're using a UITextField.

Declare your view controller to adopt the UITextFieldDelegate protocol, and set the delegate of the text field to the view controller.

In the view controller, implement this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    string = [string lowercaseString];
    textField.text = [textField.text stringByReplacingCharactersInRange:range
        withString:string];
    return NO;
}

If you are using a UITextView, adopt the UITextViewDelegate protocol and implement the textView:shouldChangeTextInRange:replacementText: method.

What you can do is make the string of the text box lowercase after they close the keyboard. For example, 

[sender resignFirstResponder];
textField.text = textField.text.lowercaseString;

This makes the text lowercase when they close the keyboard, which does what you want.
