Objective C 代表 Swift

Question

我刚刚在我所有的 swift 应用程序中实施了 Chartboost。

我奖励了插页式广告。所以我需要使用 Chartboost 给我的 objective C 函数设置一个委托。我不知道该怎么做。这就是我通过 Swift.

执行 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)

但是我得到的 Objective C Chartboost 函数是：

(void)didCompleteRewardedVideo:(CBLocation)位置 withReward:(int)reward;

而且我不明白如何使用此函数创建与 Admob 相同的委托。这似乎不可能。我有 Chartboost 奖励插页式广告。但是我没有办法设置代表看他们是否看完了视频。

如果你想实现 objective-c 委托给 swift。您需要执行以下步骤。

需要创建桥接文件来导入您的 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.
