ios remote keyboard window

问题

In iOS 9, I see a new window appearing in my app that I didn't see before. An image is below. From walking the view tree, I suspect it may be coming from the UIRemoteKeyboardWindow -- but I don't know that. What is it, and what do I have to do to keep it from appearing?

EDIT: As a commenter pointed out, this is tied to the inputView, i.e. the keyboard. I don't want a keyboard and so disabled it by calling

    self.inputView = [[UIView alloc]initWithFrame: CGRectZero];

That did kill the keyboard, but there is still the accessory. I've tried similar tricks to kill the accessory; none of them have worked, yet. Calling self.inputAccessoryView is returning nil, which doesn't help.

回答1:

This got rid of it:

-(void) killAccessory {
    UIView* input = self.inputView;
    UIView* parent = input.superview;
    parent.hidden = YES;
}

-(BOOL) becomeFirstResponder {
    BOOL r = [super becomeFirstResponder];
    [self killAccessory];
    return r;
}

You can use the following code :

textField.inputAssistantItem.leadingBarButtonGroups = [[NSArray alloc] init];
textField.inputAssistantItem.trailingBarButtonGroups = [[NSArray alloc] init];

the textField use above is the textField which you tap to edit.
