Ios 我将如何在swift中实施该协议？

如果我有一个名为MyIntersitial的类，我将如何在其中实现这个objective c协议。任何提示都将不胜感激。我刚刚得到“不符合协议”错误

Swift:

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

#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

Objective-c协议：

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

#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

#导入
#导入“gadcustomeventraldelegate.h”
#导入“GADCustomEventRequest.h”
@协议间性
@属性（非原子，弱）id委托；
-（void）RequestInterstitutionAladWithParameter:（NSString*）服务器参数
标签：（NSString*）服务器标签
请求：（GADCustomEventRequest*）请求；
-（void）presentFromRootViewController:（UIViewController*）rootViewController；
@结束

您必须在协议之前列出一个超类（或NSObject）。我还建议您将类名大写

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
    }
}

您是否将GADCustomEventInterstitual添加到“xxx桥接头.h”中？按cmd并单击GADCustomEventInterstitial时，它的确切位置在哪里？
