Question

我刚刚将Chartboost应用到了我的全部应用程序中。

我已经奖励插页式广告。所以我需要使用Chartboost给我的目标C函数设置一个委托。我无法弄清楚该怎么做。这就是我通过Swift做Admob的方式。

   NSNotificationCenter.defaultCenter().addObserver(self, selector: "presentInterstitial:", name: "AdMobCall", object: nil) 

   func presentInterstitial(sender:UIButton!) {

    if let isReady = interstitial?.isReady {   // _ isReady
        interstitial?.presentFromRootViewController(self)

    }
}

 NSNotificationCenter.defaultCenter().postNotificationName("AdMobCall", object: nil)

但我给出的Objective C Chartboost函数是：

（无效）didCompleteRewardedVideo：（CBLocation）位置 withReward：（INT）奖励;

我不明白如何使用此功能为Admob创建相同的委托。这似乎不可能。我有Chartboost奖励的部门工作。但我无法设置代表，看看他们是否观看了视频是否已完成。

如果你想实现objective-c委托给swift。您需要执行以下步骤。

需要创建桥文件以导入objective-c类

//
//  Use this file to import your target's public headers that you would like to expose to Swift.
//

#import "UVIViewController.h"

您需要在swift viewcontroller中扩展协议名称

import UIKit

class ViewController: UVIViewController, UVIDataRefreshProtocol {   // 2. Extend Protocal

    var secondController: DelegateViewController?

    @IBOutlet var delegateRefresh: UILabel!

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

        self.registerForBasicDataRefreshNotification();             //  3. Register the protocol notification
    }

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

    // Register the protocol notification with same name. Example : DataRefreshNotification
    override func registerForBasicDataRefreshNotification() {

        self.validateBasicDataRefreshNotification();
        NSNotificationCenter.defaultCenter().addObserver(        // 4. Register the protocol notification with same name.
            self,
            selector: "basicDataDidRefresh",
            name: DataRefreshNotification,
            object: nil)

    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        delegateRefresh.text = "";
        if segue.identifier == "view_to_delegate" {
            secondController = segue.destinationViewController as? DelegateViewController
        }
    }

    // Basic Data Did Refresh Notification
    func basicDataDidRefresh() {                            //  4. Event will be triggered while calling the protocol post notification. called with same name
            NSLog("\n Basic data is refreshed")
            delegateRefresh.text = "Basic data is refreshed";
    }

}

    5. NSNotificationCenter.defaultCenter().postNotificationName(DataRefreshNotification, object: nil)  // Call the notification.
