iOS Trying to convert object to NSMutableArray

[johnmerlino]

Hey all,

I'm using JSONKit.

NSDictionary *resultsDictionary = [response objectFromJSONString];
        NSLog(@"the value is %@", resultsDictionary);
        units = [resultsDictionary allValues];

That NSLog outputs this:

the value is (
        {
        unit =         {
            "account_id" = 66;
            "act_exp_date" = "<null>";
            "activation_state" = 2;
            "airtime_plan" = 1;
            "created_at" = "<null>";
            enabled = 1;
            "firmware_version" = "<null>";
            "gateway_ip" = "<null>";
            "hardware_revision" = "<null>";
            icon = "<null>";
            id = 1111;
            "is_speeding" = 0;
            name = 1111;
            "sim_number" = "<null>";
            "sim_phone" = "<null>";
            "speed_limit" = "<null>";
            "speed_limit_enabled" = 0;
            "unit_group_id" = "<null>";
            "unit_type_id" = 2;
            "updated_at" = "2011-10-31T15:26:31Z";
        };
    },
        {
        unit =         {
            "account_id" = 2;
            "act_exp_date" = "2011-09-23";
            "activation_state" = 2;
            "airtime_plan" = 1;
            "created_at" = "2011-09-06T16:10:38Z";
            enabled = 1;
            "firmware_version" = "<null>";
            "gateway_ip" = "<null>";
            "hardware_revision" = "<null>";
            icon = "<null>";
            id = 1113;
            "is_speeding" = 0;
            name = 1113;
            "sim_number" = "<null>";
            "sim_phone" = "<null>";
            "speed_limit" = "<null>";
            "speed_limit_enabled" = 0;
            "unit_group_id" = 1;
            "unit_type_id" = 1;
            "updated_at" = "2011-10-25T13:22:21Z";
        };
    },
        {
        unit =         {
            "account_id" = 2;
            "act_exp_date" = "2011-01-01";
            "activation_state" = 2;
            "airtime_plan" = 1;
            "created_at" = "2011-09-26T16:35:45Z";
            enabled = 1;
            "firmware_version" = "<null>";
            "gateway_ip" = "<null>";
            "hardware_revision" = "<null>";
            icon = "";
            id = 1114;
            "is_speeding" = 0;
            name = 1114;
            "sim_number" = "<null>";
            "sim_phone" = "<null>";
            "speed_limit" = "<null>";
            "speed_limit_enabled" = 0;
            "unit_group_id" = "<null>";
            "unit_type_id" = 2;
            "updated_at" = "2011-10-25T13:22:21Z";
        };
    },
        {
        unit =         {
            "account_id" = 2;
            "act_exp_date" = "2012-01-01";
            "activation_state" = 2;
            "airtime_plan" = 1;
            "created_at" = "2011-09-26T16:37:52Z";
            enabled = 1;
            "firmware_version" = "<null>";
            "gateway_ip" = "<null>";
            "hardware_revision" = "<null>";
            icon = "";
            id = 1115;
            "is_speeding" = 0;
            name = 1115;
            "sim_number" = "<null>";
            "sim_phone" = "<null>";
            "speed_limit" = "<null>";
            "speed_limit_enabled" = 0;
            "unit_group_id" = "<null>";
            "unit_type_id" = 1;
            "updated_at" = "2011-10-25T13:22:21Z";
        };
    }
)

However, since I want to populate this data in a table, I want to convert it to an NSMutable array.

But when I call this:

units = [resultsDictionary allValues];

When the application runs, I get an error:

 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[JKArray allValues]: unrecognized selector sent to instance 0x6ba9b00'

thanks for response

Seems to me your response is already an array (of unit dictionaries).

 

[jnoxx]

JsonKit, provides arrays of dictionarys.
So best is to turn your units in an array.
You need to do something like this

for (NSDictionary *dict in units) {
 Model *model = [[Model alloc] init];
 model.property = [dict objectForKey:@"stringName"];
 model.property2 = [dict objectForKey:@"stringName2"];
 [SingletonArray addObject:model];
 [model release];
}

Hope that helped you out in some way.

thanks for response, I dont understand what SingletonArray is supposed to be. Is that just supposed to be an NSMutableArray that I create?

 

[jnoxx]

I normally use an Singleton to make a manager that will hold all my NSMutableArrays, but yes, that's the idea.

Solve using try catch

@try {
                resultArray = [[NSMutableArray alloc]initWithArray:[statusInDictionary objectForKey:@"testseting"]];
            }
            @catch (NSException *exception) {
                resultArray = [[NSMutableArray alloc]initWithObjects:[statusInDictionary objectForKey:@"test"],nil];
            }
            @finally {
                NSLog(@"resultArray  %@",resultArray );
            }
