Google Sheet API batch update issue iOS

Question

Am trying to do a batch update with google sheet API for iOS but am getting an error invalid value at 'data[0].values[0]' (type.googleapis.com/google.protobuf.ListValue),

here is my code

 NSString *baseUrl = @"https://sheets.googleapis.com/v4/spreadsheets/";
NSString *spreadsheetId = @"1tJd4toWFxmHAEOeONauRPcuH_rWJOESLQT7TvCIK0x0";

baseUrl= [baseUrl stringByAppendingString:spreadsheetId];
baseUrl = [baseUrl stringByAppendingString:@"/values:batchUpdate/"];



NSMutableDictionary * params=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"USER_ENTERED",@"valueInputOption", nil];

NSURL *postURL=[GTLUtilities URLWithString:baseUrl queryParameters:params];

NSLog(@"base url is %@", postURL);

GTLObject * body=[[GTLObject alloc]init];



NSMutableArray * titleArray=[[NSMutableArray alloc]initWithObjects:@"Customer ID",@"Customer Name",@"Latitude",@"Longitude" ,@"Last_Updated_At",nil];
NSMutableArray * wheelArray2=[[NSMutableArray alloc]initWithObjects:@"rt",@"SHJ",@"150.00",@"100.00",@"2:00:00", nil];

//[contentArray addObject:titleArray];



NSMutableDictionary * batchParams=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"USER_ENTERED",@"valueInputOption", nil];


NSMutableArray * batchParametersContentArray=[[NSMutableArray alloc]init];


NSMutableDictionary*  batchParametersTitlesDict=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"Sheet1!A1:E1",@"range",@"COLUMNS",@"majorDimension",titleArray,@"values", nil];


NSMutableDictionary*  batchParametersContentDict=[[NSMutableDictionary alloc]initWithObjectsAndKeys:@"Sheet1!A7:E7",@"range",@"ROWS",@"majorDimension",wheelArray2,@"values", nil];


[batchParametersContentArray addObject:batchParametersTitlesDict];

[batchParametersContentArray addObject:batchParametersContentDict];

[batchParams setObject:batchParametersContentArray forKey:@"data"];


NSLog(@"batch params are %@",batchParams);


body.JSON=batchParams;


[self.service fetchObjectByInsertingObject:body forURL:postURL completionHandler:^(GTLServiceTicket *ticket, id object, NSError *error) {
    if (error==nil) {
        NSLog(@"batch performed successfully");
    }
    else
    {
        NSLog(@"error is %@", error);
    }

}];

My Request parameters are

batch params are {
data =     (
            {
        majorDimension = COLUMNS;
        range = "Sheet1!A1:E1";
        values =             (
            "Customer ID",
            "Customer Name",
            Latitude,
            Longitude,
            "Last_Updated_At"
        );
    },
            {
        majorDimension = ROWS;
        range = "Sheet1!A7:E7";
        values =             (
            rt,
            SHJ,
            "150.00",
            "100.00",
            "2:00:00"
        );
    }
);
valueInputOption = "USER_ENTERED";
}

The error is

error is Error Domain=com.google.GTLJSONRPCErrorDomain Code=400 "(Invalid value at 'data[0].values[0]' (type.googleapis.com/google.protobuf.ListValue), "Customer ID"

Answer 1

Values are intended to be a 2d array. They should be in the form of [[ 'a', 'b', 'c'], [ 1, 2, 3 ]]

You're supplying the values as a 1d array ['a', 'b', 'c'], and the error message is complaining the 'a' can't fit into a ListValue since it's not an array. The solution is to use a 2d array, although I can't provide an example here of exactly what you should do since I'm not sure how you intend your input to map to the spreadsheet.
