如何在swift 3中的UItextField中使用波斯数字？ [英] how to use persian numbers in UItextField in swift 3?

问题描述

您好我在我的swift3应用程序中使用文本字段 - 我希望当用户在文本字段中输入数字而不是英文编号时，textfield显示波斯数字 - 我的文本字段键盘设置为只输入数字，因此用户无法使用带键盘的文本字段内的文本，所以这里是我的代码不起作用

Hi I am using text field in my swift3 application - I want when user enter a number in the text field instead of english number textfield shows persian numbers - my textfield keyboard has set to just enter number so the user can't use text inside the text field with keyboard so here is my codes that doesn't work

  override func viewDidLoad() {
         super.viewDidLoad()
 let numberFormatter = NumberFormatter()
    numberFormatter.locale = Locale(identifier: "fa")
    numberFormatter.numberStyle = NumberFormatter.Style.decimal
    let cm:Int? = Int(englishNumber.text!)

    if cm != nil {
    numberFormatter.string(from: NSNumber(value: cm!))
    myTextField.text = numberFormatter.string(from: NSNumber(value: cm!))!
    }

**记得我使用了textfield Delegate，我想要用户输入的每个号码更改为波斯语编号，用户认为编写波斯语编号**

**remember that I used textfield Delegate and I want every Number that user entered change to Persian number and the user thought that writing Persian Numbers **

推荐答案

试试这个：

 func convertEngNumToPersianNum(num: String)->String{
        let number = NSNumber(value: Int(num)!)
        let format = NumberFormatter()
        format.locale = Locale(identifier: "fa_IR")
        let faNumber = format.string(from: number)

        return faNumber!
    }
