Question

我是swift的新手，我正在研究代表和协议。在我的测试应用程序中，我正在使用此协议声明（在ViewController1中），我有这个代码：

 import UIKit

//Protocol declaration

protocol viewController1Delegate

{

    func didFinish(controller:ViewController1,text:String)
}

// ViewController1类

class ViewController1: UIViewController {

//delegate declaration for viewController1
var delegate:ViewController1? = nil


override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.
    valore.text=valoreInput
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

@IBAction func doneWithOK(sender: AnyObject) {

    delegate?.didFinish(self,"done")
}
}

我的问题是XCode向我显示错误：ViewController1没有名为didFinisch的成员。我的代码有什么问题？有人可以帮我理解这个问题吗？

Answer 1

delegate应该是viewController1Delegate?而不是ViewController1?。
