无法将Realm与iCloud同步

Question

我正在尝试将我的应用中的Realm与iCloud/CloudKit同步,但没有成功......

这是我的源代码:

-(void)sync
{
    NSURL *baseURL = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];

    if (baseURL) //iCloud is active
    {
        NSURL *serverURL = [NSURL URLWithString:@"http://myMacBookNwtworkIP:9080"]; //Realm Object Server is up and running at this URL
        RLMSyncCredential *usernameCredential = [RLMSyncCredential credentialWithUsername:@"myUsername"
                                                                                 password:@"myPassword"
                                                                                  actions:RLMAuthenticationActionsUseExistingAccount];
        RLMSyncCredential *iCloudCredential = [RLMSyncCredential credentialWithICloudToken:@"myiCloudToken"];

        [RLMSyncUser authenticateWithCredential:usernameCredential
                                  authServerURL:serverURL
                                   onCompletion:^(RLMSyncUser *user, NSError *error) {
                                       if (user) { //user recognized in my real object server
                                           // can now open a synchronized RLMRealm with this user
                                           RLMRealmConfiguration *config = [RLMRealmConfiguration defaultConfiguration];
        /* CRASH AT THIS LINE! */          config.syncConfiguration = [[RLMSyncConfiguration alloc] initWithUser:user realmURL:serverURL];
                                           RLMRealm *realm = [RLMRealm realmWithConfiguration:config error:nil];// Any changes made to this Realm will be synced across all devices!
                                       } else if (error) {
                                           // handle error
                                           NSLog(@"error %@",error);
                                       }
                                   }];
    }
}

当我试图执行

config.syncConfiguration = [[RLMSyncConfiguration alloc] initWithUser:user realmURL:serverURL];

我收到这个错误

提供的URL(http:// myMacBookNwtworkIP:9080)不是有效的域URL.

我该如何解决？

另外,由于这是我第一次尝试在iCloud中保存一些东西,我该如何使用iCloudCredential？事实上,如果我usernameCredential用它替换,那么user总是没有...

我按照这些链接的步骤:

2. https://realm.io/docs/realm-object-server/#authentication

Answer 1

为了防止崩溃，需要指定“realm”协议而不是“http”，如下所示

config.syncConfiguration = [[RLMSyncConfiguration alloc] initWithUser:user realmURL:[NSURL URLWithString:@"realm://myMacBookNwtworkIP:9080"]];
