AppLovin SDK for iOS 发生“无法识别的选择器发送到实例”错误

Question

我正在尝试以下步骤来集成 AppLovin for iOS，但出现错误您知道如何解决此问题吗？

1. 下载 AppLovin SDK for iOS 并将 AppLovinSDK.framework 拖到我的项目中。
2. 添加依赖框架。
   • 广告支持
   • AVFoundation
   • CoreGraphics
   • CoreMedia
   • 核心电话
   • StoreKit（新）
   • 系统配置
   • UIKit
   • WebKit（可选）
3. 将我的 AppLoin SDK 密钥添加到 info.plist。

4. 将初始化 sn-ps 添加到 AppDelegate.m。

   #import <AppLovinSDK/AppLovinSDK.h>
   // ...
   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
       // Override point for customization after application launch.
       [ALSdk initializeSdk];
       return YES;
   }
   

5. 添加 sn-ps 以向 ViewController.m 展示广告。

   #import <AppLovinSDK/AppLovinSDK.h>
   // ...
   - (void)viewDidLoad {
       [super viewDidLoad];
       if([ALInterstitialAd isReadyForDisplay]){
           [ALInterstitialAd show];
       }
       else{
           NSLog(@"Failed");
       }
   }
   

6. 运行应用程序并出现以下堆栈跟踪错误：

Here 是关于如何集成 AppLovin SDK for iOS 的文档。 （它应该已登录。）

Answer 1

我没有意识到官方文档中的某些句子。为了解决这个问题，我需要启用 Xcode Flags。

启用 Xcode 标志 必须添加 -ObjC 标志才能使静态库（例如我们的 SDK）正确运行。
