如何使用 Swift 语言显示 AdMob 应用打开广告? [英] How to show AdMob app open ads using Swift language?

问题描述

之前，我在 iOS 应用中使用了 AdMob 的横幅广告.现在，我想展示其最新发布的开放应用广告.我查看了 AdMob 的相关网页(在此处输入链接描述)，但是这个页面上的例子都是OC语言的.我不熟悉OC语言.谁能提供 Swift 语言的指导?提前致谢.

Before, I used AdMob's banner ad in an iOS app. Now, I want to show its latest released open app ads. I checked the relevant web page of AdMob (enter link description here), but the examples on this page are all in OC language. I am not familiar with OC language. Can anyone provide guidance in Swift language? Thanks in advance.

推荐答案

OC 代码在这里:https://developers.google.com/admob/ios/app-open-ads

下面的所有代码都转到 AppDelegate.swift

All code below goes to AppDelegate.swift

导入 GoogleMobileAds:

import GoogleMobileAds

在类定义中添加GADFullScreenContentDelegate:

class AppDelegate: UIResponder, UIApplicationDelegate, GADFullScreenContentDelegate {

添加两个变量:

var appOpenAd: GADAppOpenAd?
var loadTime = Date()

添加这三个函数:

func requestAppOpenAd() {
    let request = GADRequest()
    GADAppOpenAd.load(withAdUnitID: "YOUR_ADUNIT_ID",
                      request: request,
                      orientation: UIInterfaceOrientation.portrait,
                      completionHandler: { (appOpenAdIn, _) in
                        self.appOpenAd = appOpenAdIn
                        self.appOpenAd?.fullScreenContentDelegate = self
                        self.loadTime = Date()
                        print("Ad is ready")
                      })
}

func tryToPresentAd() {
    if let gOpenAd = self.appOpenAd, let rwc = self.window?.rootViewController, wasLoadTimeLessThanNHoursAgo(thresholdN: 4) {
        gOpenAd.present(fromRootViewController: rwc)
    } else {
        self.requestAppOpenAd()
    }
}

func wasLoadTimeLessThanNHoursAgo(thresholdN: Int) -> Bool {
    let now = Date()
    let timeIntervalBetweenNowAndLoadTime = now.timeIntervalSince(self.loadTime)
    let secondsPerHour = 3600.0
    let intervalInHours = timeIntervalBetweenNowAndLoadTime / secondsPerHour
    return intervalInHours < Double(thresholdN)
}

最后从applicationDidBecomeActive()调用tryToPresentAd():

func applicationDidBecomeActive(_ application: UIApplication) {
    self.tryToPresentAd()
}

就是这样.

添加了导入GoogleMobileAds
