我将如何在 swift 中实施此协议？

Question

如果我有一个名为 myIntersitital 的 class，我将如何在其中实施此 objective c 协议。任何提示将不胜感激。我刚收到 'does not conform to protocol' 错误。

Swift:

import Foundation
import GoogleMobileAds
class myInterstitial: GADCustomEventInterstitial{
//... implements here
}

Objective-c 协议：

#import <UIKit/UIKit.h>
#import "GADCustomEventInterstitialDelegate.h"
#import "GADCustomEventRequest.h"


    @protocol GADCustomEventInterstitial<NSObject>

    @property(nonatomic, weak) id<GADCustomEventInterstitialDelegate> delegate;


    - (void)requestInterstitialAdWithParameter:(NSString *)serverParameter
                                         label:(NSString *)serverLabel
                                       request:(GADCustomEventRequest *)request;

    - (void)presentFromRootViewController:(UIViewController *)rootViewController;

    @end

您必须在协议前列出一个超级class（或 NSObject）。我还建议您将 class 名称大写。

import Foundation

class MyInterstitial: NSObject, GADCustomEventInterstitial {

    var delegate: GADCustomEventInterstitialDelegate?

    func requestInterstitialAdWithParameter(serverParameter: String!, label serverLabel: String!, request: NSObject!) {
        // implementation here
    }

    func presentFromRootViewController(rootViewController: UIViewController!) {
        // implementation here
    }
}

我将如何在 swift 中实施此协议？

How would I implement this protocol in swift?
