Custom Keyboard covers standard inputView - ios

Question

I've created a custom inputView for the standard iOS keyboard and it works perfectly fine in both iOS 7 and 8.
But when using 3rd-party custom keyboard, it covers my created inputView. It shows the custom inputView for a second, and covers it with the custom keyboard view. I've tried several different custom keyboards, and they all have the same problem.
Is it possible to use inputView on any kind of keyboards? If possible, how to do it?
Thanks in advice!

Answer 1

I met the same problem and I found that using a view that is managed by a view controller will lead to this issue.
I made a simple demo to demostrate it:
As code shown below, toggleInputView will create a input view that work for both system keyboard and third party keyboard, while toggleInputViewController will only work for system keyboard.
import UIKit
class CustomInputViewController: UIViewController {
override func viewDidLoad() {
self.view.frame = CGRect(x: 0, y: 0, width: 300, height: 200)
}
}
class ViewController: UIViewController {
var customInputViewController: CustomInputViewController?
#IBOutlet weak var textView: UITextView!
#IBAction func toggleInputView(sender: AnyObject) {
if textView.inputView == nil {
textView.inputView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 200))
} else {
textView.inputView = nil
}
self.textView.reloadInputViews()
}
#IBAction func toggleInputViewController(sender: AnyObject) {
if textView.inputView == nil {
if self.customInputViewController == nil {
self.customInputViewController = CustomInputViewController()
}
self.textView.inputView = self.customInputViewController!.view
} else {
self.textView.inputView = nil
}
self.textView.reloadInputViews()
}
}
As a result, you can build a input view by subclass UIView to resolve your problem.
