As of iOS 9 beta 2, the documentation is still very thin on the ground (and vaguely misleading) but I've had success using this UITextFieldDelegate method implementation.

- (void)textFieldDidBeginEditing:(UITextField*)textField  
{  
    UITextInputAssistantItem* item = [textField inputAssistantItem];  
    item.leadingBarButtonGroups = @[];  
    item.trailingBarButtonGroups = @[];  
}
