Question

class ViewController: UIViewController,UITextFieldDelegate,MRCountryPickerDelegate {


 override func viewDidLoad() {
        super.viewDidLoad()


     countryPicker.countryPickerDelegate = self
     countryPicker.showPhoneNumbers = true
     countryPicker.setCountry("SI")
 }

在countryPicker.countryPickerDelegate = self

上发生错误

我试图解决但却无法解决问题......并且给了我这个错误：

螺纹-1- EXC-坏存取码-2 -

我正在使用MRCountrypickerlibrary。

类实现代码：

open class MRCountryPicker: UIPickerView, UIPickerViewDelegate, UIPickerViewDataSource {

var countries: [Country]!
open weak var countryPickerDelegate: MRCountryPickerDelegate?
open var showPhoneNumbers: Bool = true

override init(frame: CGRect) {
    super.init(frame: frame)
    setup()
}

required public init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    setup()
}

func setup() {
    countries = countryNamesByCode()

    super.dataSource = self
    super.delegate = self
}

// MARK: - Country Methods

open func setCountry(_ code: String) {
    var row = 0
    for index in 0..<countries.count {
        if countries[index].code == code {
            row = index
            break
        }
    }

    self.selectRow(row, inComponent: 0, animated: true)
    ****let country = countries[row]****
    if let countryPickerDelegate = countryPickerDelegate {
        countryPickerDelegate.countryPhoneCodePicker(self, didSelectCountryWithName: country.name!, countryCode: country.code!, phoneCode: country.phoneCode!, flag: country.flag!)
    }

更新的代码在上面，它是MRCountryPicker的定义

这是我的pod文件：

# Uncomment the next line to define a global platform for your project
 platform :ios, '9.0'

target 'myapp' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for myapp
    pod 'MRCountryPicker'
end

当您在故事板中初始化选择器时，您将在身份检查员处看到自定义课程部分。您必须将类和模块都设置为MRCountryPicker。否则你会收到错误。
