ios - Remove Next / Previous buttons (inputAccessoryView) for Custom Keyboard in iOS8 WebView

Question

Please bear with me, I searched a lot over the internet and I couldn't find a solution since it's a new API.

I am trying to create a custom keyboard for iOS 8. It works perfectly fine except in WebView! It has previous-next button, which are in inputAccessoryView. I know it's read-only property for webview but since iOS 8 allows the users to have custom keyboard I assume this view should be editable somewhere. Has anybody run into the same issue? Any help would be appreciated.

You may try and improve this. try call this function inside Your UIKeyboardDidShowNotification event handler.

-(void) removeKeyboard {
    UIWindow *keyboardWindow = nil;
    for (UIWindow *testWindow in [[UIApplication sharedApplication] windows]) {
        if (![[testWindow class] isEqual : [UIWindow class]]) {
            keyboardWindow = testWindow;
            break;
        }
    }
    // Locate UIWebFormView.
    for (UIView *possibleFormView in [keyboardWindow subviews]) {

        if ([[possibleFormView description] hasPrefix : @"<UIInputSetContainerView"]) {
            for (UIView* peripheralView in possibleFormView.subviews) {

                for (UIView* peripheralView_sub in peripheralView.subviews) {


                    // hides the backdrop (iOS 8)
                    if ([[peripheralView_sub description] hasPrefix : @"<UIKBInputBackdropView"] && peripheralView_sub.frame.size.height == 44) {
                        [[peripheralView_sub layer] setOpacity : 0.0];

                    }
                    // hides the accessory bar
                    if ([[peripheralView_sub description] hasPrefix : @"<UIWebFormAccessory"]) {


                        for (UIView* UIInputViewContent_sub in peripheralView_sub.subviews) {

                            CGRect frame1 = UIInputViewContent_sub.frame;
                            frame1.size.height = 0;
                            peripheralView_sub.frame = frame1;
                            UIInputViewContent_sub.frame = frame1;
                            [[peripheralView_sub layer] setOpacity : 0.0];

                        }

                        CGRect viewBounds = peripheralView_sub.frame;
                        viewBounds.size.height = 0;
                        peripheralView_sub.frame = viewBounds;

                    }
                }

            }
        }
    }

}

Hope this helps...

This is the level of views in accessory:

(UIWebFormAccessory) -> (UIToolbar) -> (UIImageView,UIToolbarButton,UIToolbarButton)

Removing or scaling to zero height the accessory bar will cause black area. You can play around the mainview's frame or bounds. or if You just want to get rid of the buttons, just try to have a 0 opacity on the UIToolbutton , the toolbutton is inside uitoolbar view
