My current assignment is an iOS Keyboard Extension. Now, to pass App Store Review, the containing app has to provide some "real" content. I thought about letting the user test the keyboard before enabling it in the Settings. So my storyboard looks like this (reduced to show relevant stuff):
└ ViewController
└ View
├ TextField
└ Keyboard Container
└ KeyboardViewController
This works all right, the keyboard shows in the container, but - as the textDocumentProxy object in the keyboard's view controller isn't attached to anything - the user can't see what s/he's typing.
Now I'm looking for a way to "attach" the keyboard to the text field, while keeping the system keyboard out of the way so the user can type on the custom one.
I already managed to get the system keyboard away by attaching the following function to the textfield's editing did begin action.
@IBAction func editingBegan(sender: UITextField) {
sender.endEditing(true)
}
