How do I set Custom Keyboad as a default keyboard to UITextView? - swift

Question

I've created custom keyboard and it works fine. But I don't know how to set my custom keyboard to specific UITextField.
This is my KeyboardViewController
import UIKit
class KeyboardViewController: UIInputViewController {
#IBOutlet var nextKeyboardButton: UIButton!
#IBOutlet weak var percentView: UIView!
#IBOutlet weak var hideKeyboardButton: UIButton!
override func updateViewConstraints() {
super.updateViewConstraints()
// Add custom view sizing constraints here
}
override func viewDidLoad() {
super.viewDidLoad()
// Perform custom UI setup here
self.nextKeyboardButton = UIButton(type: .System)
self.nextKeyboardButton.setTitle(NSLocalizedString("Next Keyboard", comment: "Title for 'Next Keyboard' button"), forState: .Normal)
self.nextKeyboardButton.sizeToFit()
self.nextKeyboardButton.translatesAutoresizingMaskIntoConstraints = false
self.nextKeyboardButton.addTarget(self, action: "advanceToNextInputMode", forControlEvents: .TouchUpInside)
self.view.addSubview(self.nextKeyboardButton)
let nextKeyboardButtonLeftSideConstraint = NSLayoutConstraint(item: self.nextKeyboardButton, attribute: .Left, relatedBy: .Equal, toItem: self.view, attribute: .Left, multiplier: 1.0, constant: 0.0)
let nextKeyboardButtonBottomConstraint = NSLayoutConstraint(item: self.nextKeyboardButton, attribute: .Bottom, relatedBy: .Equal, toItem: self.view, attribute: .Bottom, multiplier: 1.0, constant: 0.0)
self.view.addConstraints([nextKeyboardButtonLeftSideConstraint, nextKeyboardButtonBottomConstraint])
let nib = UINib(nibName: "KeyboardView", bundle: nil)
let objects = nib.instantiateWithOwner(self, options: nil)
view = objects[0] as! UIView;
for view in self.view.subviews {
if let btn = view as? UIButton {
btn.layer.cornerRadius = 5.0
btn.translatesAutoresizingMaskIntoConstraints = false
//btn.addTarget(self, action: "keyPressed:", forControlEvents: .TouchUpInside)
}
}
}
and other delegate methods. So how can I call this ?
Actually the problem is I couldn't import custom keyboard classes from app extension. That's the main problem. I did this all build phases stuff. And I can use the keyboard if I change keyboard myself.

According Apple Documentation
After a user chooses a custom keyboard, it becomes the keyboard for every app the user opens.
Therefor it's not like your app specific thing, it's more like different languages keyboards. As far as you can't specify some specific language keyboard for your UITextField or UITextView you can't specify your custom keyboard as well.
Are you sure that you need Custom Keyboard instead of custom view for data input inside your app? About custom data input views you can read here.
