Google sheets 在谷歌表单上插入数据

我有这样一个代码，可以在Google表单中插入数据，但只能在直线上插入：

NSArray *Worksheets = [mWorksheetFeed entries];

if ( [Worksheets count] > 0)
    [self fetchSelectedWorksheet];



NSArray *entries = [mEntryFeed entries];

for (int l=0; l < [entries count]; l++)
{
    GDataFeedBase *entry = [entries objectAtIndex:l];
    GDataSpreadsheetCell *cell = [(GDataEntrySpreadsheetCell *)entry cell];

    NSLog(@"%@-%@-%@",[cell resultString], [cell inputString], [[entry title] stringValue]);

}
if ([entries count]>0)
{
    GDataEntrySpreadsheetCell * lastCell = [entries lastObject];
    NSString * title = [[lastCell title] stringValue];
    NSString * lastRow = [[title componentsSeparatedByCharactersInSet:
                           [[NSCharacterSet decimalDigitCharacterSet] invertedSet]]
                          componentsJoinedByString:@""];

    for (int l = 0; l < resultRow.count; l++ )
    {
        GDataSpreadsheetCell * cell = [GDataSpreadsheetCell cellWithRow:[lastRow intValue] + 1 column:l+1 inputString:[resultRow objectAtIndex:l] numericValue:nil resultString:nil];

        // create a cellEntry object that will contain the cell
        GDataEntrySpreadsheetCell * cellEntry = [GDataEntrySpreadsheetCell spreadsheetCellEntryWithCell:cell];

        // upload the cellEntry to your spreadsheet
        GDataServiceGoogleSpreadsheet *service = [self spreadsheetService];
        GDataEntryWorksheet *worksheet = [self selectedWorksheet];
        [service fetchEntryByInsertingEntry:cellEntry
                                 forFeedURL: [[worksheet cellsLink] URL]
                                   delegate:self
                          didFinishSelector:nil];
    }
}

现在，我想做的是，而不是一个直行，将一个数据从UITextField插入到任何特定的单元格中，例如，对于第一个文本字段，我希望它是C5，第二个文本字段插入G11。

这是一个iOS 7特定的问题吗？
