Question

我可以通过参考iPhone: Change Keyboard language programmatically将键盘语言从ja-JP更改为vi-VN。但是我无法在同一代码上将vi-VN更改为en-US。

我不知道为什么会这样，但我已解决。解决方法是我总是在更改其他语言之前设置语言ja-JP（请参阅my project）。

此项目重现了问题。但是启用func selectLanguage中的BEGIN：至END：块将解决此问题。

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var textField: UITextField!
var lang = "en-US"

@IBAction func selectLanguage(_ sender: UISegmentedControl) {
    // BEGIN: Changing Keyboard language en-US to vi-VN is working if this comment this block out.
//        lang = "ja-JP"
//        self.textField.resignFirstResponder()
//        self.textField.becomeFirstResponder()
    // END:   Changing Keyboard language en-US to vi-VN is working if this comment this block out.

    switch sender.selectedSegmentIndex {
    case 0: // English
        lang = "en-US"
    case 1: // Vietnamese
        lang = "vi-VN"
    case 2: // Japanese
        lang = "ja-JP"
    default:
        break
    }

    // ReDisplay Keyboard
    self.textField.resignFirstResponder()
    self.textField.becomeFirstResponder()

}

override var textInputMode: UITextInputMode?{
    var tim = super.textInputMode

    for mode in UITextInputMode.activeInputModes {
        if mode.primaryLanguage!.localizedStandardContains(lang) {
            tim = mode
        }
        print("Available Keyboard: ", mode.primaryLanguage ?? "nil")
    }

    print("Selected language: ", tim?.primaryLanguage ?? "unknown")

    return tim
}

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

}


}

我想知道解决此问题的正确方法。谢谢。
