1、事件管理工具【查看詳情】可以看到數量 ，但是查看近期事件無記錄
如果Facebook sdk 顯示在14.0.1及以下，嘗試升級版本到最新版本16.3.1
并將以下代碼添加置info.plist

<key>FacebookAdvertiserIDCollectionEnabled</key>
    <false/>
    <key>FacebookAutoInitEnabled</key>
    <true/>
    <key>FacebookAutoLogAppEventsEnabled</key>
    <true/>

在初始化sdk位置添加以下調用

    [[FBSDKSettings sharedSettings] setIsAutoLogAppEventsEnabled:YES];
    [[FBSDKSettings sharedSettings] setIsAdvertiserTrackingEnabled:YES];
    [[FBSDKSettings sharedSettings] setIsAdvertiserIDCollectionEnabled:YES];

在applicationDidBecomeActive和sceneDidBecomeActive添加以下調用

if (@available(iOS 14, *)) {
       dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
           [ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
               NSLog(@"ATT status:%lu", (unsigned long)status);
               switch (status) {
                   case ATTrackingManagerAuthorizationStatusAuthorized:
                       {
                           [[FBSDKSettings sharedSettings] setIsAdvertiserTrackingEnabled:YES];
                       }
                       break;
                   case ATTrackingManagerAuthorizationStatusDenied:
                   {
                       [[FBSDKSettings sharedSettings] setIsAdvertiserTrackingEnabled:NO];
                   }
                       break;
                   default:
                       break;
               }                
           }];
       });
   } else {
             [[FBSDKSettings sharedSettings] setIsAdvertiserTrackingEnabled:YES];
   }

根據需求可以打開Facebook sdk log 查看錯誤日志

        [[FBSDKSettings sharedSettings] enableLoggingBehavior:FBSDKLoggingBehaviorNetworkRequests];
        [[FBSDKSettings sharedSettings] enableLoggingBehavior:FBSDKLoggingBehaviorNetworkRequests];
        [[FBSDKSettings sharedSettings] enableLoggingBehavior:FBSDKLoggingBehaviorAppEvents];
        [[FBSDKSettings sharedSettings] enableLoggingBehavior:FBSDKLoggingBehaviorAccessTokens];
        [[FBSDKSettings sharedSettings] enableLoggingBehavior:FBSDKLoggingBehaviorCacheErrors];
        [[FBSDKSettings sharedSettings] enableLoggingBehavior:FBSDKLoggingBehaviorDeveloperErrors];

還可以嘗試在合適的時機重新調用Facebook sdk 的初始化方法

    [[FBSDKApplicationDelegate sharedInstance] initializeSDK];

最后就是按步驟檢查文檔接入流程是否有缺失(以app events接入為例)

對于iOS14.5+機型，未開啟AdvertiserTrackingEnabled 將無法上傳事件，在近期事件中應該是看不到的，

在事件管理工具中測試事件時

1.一定要保證ATT 自己的應用和facebook都已開啟
2.網絡正常
3.facebook登錄開發者賬號
