使用 Firebase iOS 实施 AdMob 的问题

Issues implementing AdMob with Firebase iOS(使用 Firebase iOS 实施 AdMob 的问题)

问题描述

So ever since the announcement came that iAD would be shutting down I started searching for an alternative way to monetize my app using advertisements. And with Google's May 18th updates to Firebase (integrating AdMob with it was very appealing), I decided to add a simple banner ad to my app. I followed all the instructions in the documentation (https://firebase.google.com/docs/admob/ios/quick-start#load_an_ad_into_gadbannerview) however I am unfortunately getting some critical errors.

Here is the code from the documentation, it nearly identical to my application code:

import UIKit
import GoogleMobileAds

class ViewController: UIViewController {

  @IBOutlet weak var bannerView: GADBannerView!

override func viewDidLoad() {
  super.viewDidLoad()

  bannerView.adUnitID = "ca-app-pub-3940256099942544/2934735716"
  bannerView.rootViewController = self
  bannerView.loadRequest(GADRequest())
}

} 

At @IBOutlet weak var bannerView: GADBannerView! I am getting the error: weak may only be applied to class and class-bound protocol types, not '<<error type>> Which is an error that I have never seen in my life!

I am also getting Use of unresolved identifier 'GADRequest, which I do not understand because that is a built in method from GADBannerView...?

I installed all the necessary libraries using cocoapods so that shouldn't be a problem. Any help would be appreciated. Thank you!

Is you cocoapods the newest version?

I had a similar issue with old version of cocoapods after adding firebase to my project which has GoogleMobileAds implemented already.

I got 3 build errors after I import Firebase:

"Use of unresolved identifier GADRequest"

"Use of unresolved identifier GADBannerViewDelegate"

"Use of unresolved identifier GADBannerView"

I commented import Firebase and those errors gone.

I decided to update my cocoapods and delete my old podfile.

Then use pod init to create a new podfile and add dependencies. Of course install pods again.

This works for me.

Not sure it works in your case or not, but I hope it helps.
