I'm developing SDK for Facebook(meta) and use FBSDKGraphRequest to get some data. As the demand of access-token, I want to test the case that access-token has been invalid(mostly out of time), so I generate a short term token from fb's graph developer and wait for 2 hours until it invalid. Then I build an out-of-date token and FBSDKGraphRequest. Use FBSDKGraphRequest but nothing back(no result, no error).

I generate a short term token from fb's graph developer and wait for 2 hours until it invalid.

Use these code :

FBSDKAccessToken *access_token = [[FBSDKAccessToken alloc] initWithTokenString: @"xxxxxx"(tokenString from graph developer)                                                                        permissions:@[@"public_profile",@"email", @"user_friends"]                                                                declinedPermissions:nil                                                                 expiredPermissions:nil                                                                              appID:@"xxxxxx" (my appid)                                                                             userID:@"xxxxxx"(myuserid)                                                                     expirationDate:[NSDate dateWithTimeIntervalSince1970:1717041600]                                                                        refreshDate:[NSDate dateWithTimeIntervalSince1970:1717041500]                                                           dataAccessExpirationDate:nil];     [FBSDKAccessToken setCurrentAccessToken:access_token]; 

I generate a FBSDKAccessToken which generated by out-date tokenString and test in these code :

            FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]                                           initWithGraphPath:@"/me"                                           parameters:@{ @"fields": @"picture",}                                           HTTPMethod:@"GET"];             [request startWithCompletion:^(id<FBSDKGraphRequestConnecting>  _Nullable connection, id  _Nullable result, NSError * _Nullable error) {                 NSLog(@"request back!");                 NSLog(@"fb has error:%@", error.description);                 //get picture url             }]; 

When the token is valid(not out of date), it works and has log. But when it is invalid(out of date) , there is no log(no result no error, even no "request back!".

After long time debug and searching answer on Google, I don't find similar reason. But I find FBSDKAccessToken have a func "refreshCurrentAccessTokenWithCompletion" can also get the status of the token. So I used this to judge the token's status before FBSDKGraphRequest. But something magical happened. After I add refreshCurrentAccessTokenWithCompletion, FBSDKGraphRequest works too. It shows log "request back!".

This might be a way to solve this problem. But I think there must be a method to solve this better and some root cause.

The marketing area of my company wants to create an installation campaign of an iOS app in google ads, however we can only measure the first_open event. Is there a way to directly measure app downloads in firebase analytics? to then import this event to the google ads platform

that's suddenly occured to me after i add Google-Mobile-Ads-SDK to my project and i tried to add many of frameworks but it didn't worked enter image description here
