How to display arabic keyboard or arabic input for particular UITextField?

Question

I have 2 UITextFields, first is for description in english and another is for description in Arabic. My app has localisation, but irrespective of that localisation, I need display english keyboard for english description textfield and arabic keyboard for arabic textfield. Can you guys help me on how to achieve this?

Answer 1

That's a UITextFieldDelegate method, so you need to make your View Controller conform to it. The example with English alphabet:

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    if !["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"].contains(string.lowercased()) {
        return false
    }

    return true
}

Remember to set your textfield's delegate to self (your ViewController):

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.

    engTextField.delegate = self
}

UPD: May be it's better to use !Array("qwertyuiopasdfghjklzxcvbnm").contains(string.lowercased())
