ios - How to detect when user changes keyboards? -

-

Is there a way to find out that when the user changes the keyboard type, especially in this case the Emoji keyboard for?

After the text "itemprop =" text "> UITextInputMode

you can use currentInputMode

The UITextInputMode class example shows current text-input mode. You can use this object to determine the primary language currently used for text input.

You can check the Emoji keyboard: 

  NSString * language = [[UITextInputMode current Inputmod] primary language]; BOOL isEmoji = [language acquisition: @ "emoji"]; If (isEmoji) {// do something}

If you change via UITextInputCurrentInputModeDidChangeNotification can be informed about the input mode. It will post in the current input mode after the change.

This is a simple app that prints NSLog whenever any changes occur: 

  - (zero) see { Viewedload]; [[NSNotificationCenter defaultCenter] addObserver: Self selector: @selector (changeInputMode) Name: UITextInputCurrentInputModeDidChangeNotification Object: Zero];}} - (zero) changeInputMode: (NSNotification *) Notification {NSString * inputMethod = [[UITextInputMode currentInputMode] primary language]; NSLog (@ "inputMethod =% @", inputMethod); }

or would you prefer: 

  import UIKit class ViewController: UIViewController {viewDidLoad () {super.viewDidLoad (function override) NSNotificationCenter.defaultCenter ( ) .addObserver (self selector: "changeInputMode:", name: UITextInputCurrentInputModeDidChangeNotification, object: nil)} function changeInputMode (notification: NSNotification) {go inputMethod = UITextInputMode.currentInputMode () primaryLanguage println ( "inputMethod: \ (inputMethod)") . }}
