__NSmallocblock\亚马逊AWS发电机错误-iOS

我在Dynamo AWS中遇到了一个问题，我试图从数据库中获取ID，并随机获得内存分配错误。 以下是我用来获取信息的代码：

AWSCognitoCredentialsProvider *credentialsProvider = [AWSCognitoCredentialsProvider credentialsWithRegionType:AWSRegionUSEast1
                                                                                                    accountId:AWSAccountID
                                                                                               identityPoolId:CognitoPoolID
                                                                                                unauthRoleArn:CognitoRoleUnauth
                                                                                                  authRoleArn:CognitoRoleAuth];

//Set the server connection to AWSRegionUSEast1 with the credentials
AWSServiceConfiguration *configuration = [AWSServiceConfiguration configurationWithRegion:AWSRegionUSEast1
                                                                      credentialsProvider:credentialsProvider];
[AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;
[AWSLogger defaultLogger].logLevel = AWSLogLevelVerbose;

NSString *token = FBSession.activeSession.accessTokenData.accessToken;
credentialsProvider.logins = @{ @(AWSCognitoLoginProviderKeyFacebook): token };

//Access the users table with the Facebook ID.
DDBTableRow *tableRow = [DDBTableRow new];
tableRow.UsersHash1ID = [defaults objectForKey:@"UserID"];
tableRow.UsersRange1 = [defaults objectForKey:@"UserID"];

AWSDynamoDBObjectMapper *dynamoDBObjectMapper = [AWSDynamoDBObjectMapper defaultDynamoDBObjectMapper];

//Create a load connection to the AWS Dynamo database to find out if the user already exists
[[dynamoDBObjectMapper load:[DDBTableRow class]
                    hashKey:tableRow.UsersHash1ID
                   rangeKey:tableRow.UsersRange1] continueWithExecutor:[BFExecutor mainThreadExecutor] withBlock:^id(BFTask *task) {
    if (!task.error) {
        DDBTableRow *tableRow = task.result;
        //TODO: Crashes
        if (tableRow.UsersHash1ID == nil) {// if the user does not exist.
            [self firstPlay];
        } else {
            [self SecondPlay]; //If the user exist already in the database.
        }
    } else { //Error handling
        NSLog(@"Error: [%@]", task.error);
        //TODO: handle the connection

        HUD.textLabel.text = @"Error Connecting to Database";

        [HUD dismissAfterDelay:5.0];

    }
    return nil;
}];

这就是我收到的错误：

有人知道如何解决这个问题吗？

-load:hashKey:rangeKey:

是一种异步方法。这意味着您创建的第一个

tableRow

对象可以在

-load:hashKey:rangeKey:

完成执行之前解除分配

你可以重写这一部分

[dynamoDBObjectMapper load:[DDBTableRow class]
                   hashKey:tableRow.UsersHash1ID
                  rangeKey:tableRow.UsersRange1]

差不多

[dynamoDBObjectMapper load:[DDBTableRow class]
                   hashKey:[defaults objectForKey:@"UserID"]
                  rangeKey:[defaults objectForKey:@"UserID"]]

（您正在为哈希键和范围键设置相同的值。您应该确保这是您真正想要的。）

如果它不能解决问题，您应该启用NSZombie并查看释放的对象
