Reliable method for monitoring the display or hiding of a soft keyboard in iOS

If you try to change the UI structure when the keyboard is displayed or hidden, you can rely on the notification message on the keyboard.

The UITextField proxy message is only sent when it is edited in the text area, regardless of whether a software disk is displayed on the screen.

Remember, you can use a Bluetooth keyboard to connect to an iOS device and use it to edit text areas or any other content that can be entered in your App.

When a Bluetooth keyboard is used, no keyboard is displayed on the screen. If you change the UI structure when editing the text area, there is no need to use a Bluetooth keyboard.
