You can hide it by removing all assistant bar buttons from the active textfield.

UITextField *textField = ... if ([textField respondsToSelector:@selector(inputAssistantItem)]) {     UITextInputAssistantItem *inputAssistantItem = [textField inputAssistantItem];     inputAssistantItem.leadingBarButtonGroups = @[];     inputAssistantItem.trailingBarButtonGroups = @[]; }
