Ios Swift 2-未调用协议委托

我试图实现一个

委托

，以便在主viewController中调用事件

当我尝试在

主视图控制器中调用代理时，我得到错误：

实例成员“委托”不能用于类型
“CustomPickServiceController”

我错过了什么

在我的委托文件中，我有：

protocol CustomPickerViewControllerDelegate: class {
     func CustomPickerDidSelectRow(sender:CustomPickerViewController)
}

//MARK: The Main Class
public class CustomPickerViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {

// DELEGATE
    weak var delegate: CustomPickerViewControllerDelegate?

override public func viewDidLoad() {
        super.viewDidLoad()

        customPicker.delegate = self
        customPicker.dataSource = self

.....
    }

public func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

        if component == 0 {

        }else {

        customLabel.text = arrayCustom[row]
        self.delegate?.CustomPickerDidSelectRow(self)
        }
    }


}

主视图控制器：

class ViewController: UIViewController, CustomPickerViewControllerDelegate {

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

       CustomPickerViewController.delegate = self // ERROR

    }

func CustomPickerDidSelectRow(sender: CustomPickerViewController) {
        print("ok")
    }

}

您只需像使用
CustomPickerViewController
一样进行分配即可。您需要为该视图控制器创建新对象，然后分配代理

例如：

let customPickerVC = CustomPickerViewController()
customPickerVC.delegate = self 

谢谢你这么做，我已经添加了
viewController。presentViewController
现在正在工作
