如何在没有（）或 - 快速3的情况下剥离电话号码？

Question

I am coming to a problem where I need to strip phoneNumber on my table view cell without () or - so, I want to look this way 5555555555 , so when the user clicks on the phone number it should call that particular number.

Here is my code:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    if indexPath.section == 0 {
      if indexPath.row == 2 {

        print("its working...")

        guard let phoneNumber = self.place.phoneNumber,
          phoneNumber.count > 0,

          let url = URL(string: "tel:\(phoneNumber)")

          else { return }

        if UIApplication.shared.canOpenURL(url) {
          UIApplication.shared.open(url, options: [:], completionHandler: nil)
        }
      } else { return }
    } 

Answer 1

Your goal is to create a valid tel: URL. You do not need to strip the formatting of the phone number. You just need to properly escape the special characters.

Replace:

let url = URL(string: "tel:\(phoneNumber)")

with:

let url = URL(string: "tel:\(phoneNumber.addingPercentEncoding(withAllowedCharacters: .urlPathAllowed)!)")

Answer 2

你可以用字符串中的数字去掉

let number = phoneNumber.components(separatedBy: CharacterSet.decimalDigits.inverted).joined()
