Answer 1

Try like this:

First get all values from your response in NSMutableArray what you want

@interface ViewController ()
{
    NSMutableArray *restaurentsNamesArray;
    NSMutableArray *linesArray;
    NSMutableArray *linesCountArray;
}

After that in viewDidLoad add values to those mutable arrays which you got from your response

    - (void)viewDidLoad {
        [super viewDidLoad];

        restaurentsNamesArray = [[NSMutableArray alloc]init];

        linesArray = [[NSMutableArray alloc]init];

        linesCountArray = [[NSMutableArray alloc]init];
        NSError *error;

  // Do the stuff for get response from url here.
  // And give that request below.

        NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];
                NSDictionary *main = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
                NSDictionary *result = [main valueForKey:@"result"];
                NSArray *saleorders = [result valueForKey:@"saleorders"];
                for (NSDictionary *dict in saleorders){
                    [restaurentsNamesArray addObject:[dict valueForKey:@"restaurant_name"]];
                    [linesArray addObject:[dict valueForKey:@"lines"]];
                }

        NSLog(@"%@",restaurentsNamesArray);
        NSLog(@"%@",linesArray);
    }

Now all you want is implement table view delegate methods like below:

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return [restaurentsNamesArray count];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    NSArray *array;
    if (linesArray.count > section){
        array = [linesArray objectAtIndex:section];
    }
    return array.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = [[UITableViewCell alloc]init];

    NSArray *array;
    array = [linesArray objectAtIndex:indexPath.section];
    NSDictionary *dict = [array objectAtIndex:indexPath.row];
    cell.textLabel.text = [dict valueForKey:@"line_name"];
    cell.detailTextLabel.text = [dict valueForKey:@"line_id"];
    return cell;
}
-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    return [restaurentsNamesArray objectAtIndex:section];
}

Here I'm just populating restaurant names in tableView section header as NSString .

If you want exactly like android what you shown above you have to implement below methods instead of -(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section this method

- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 50)];
    [headerView setBackgroundColor:[UIColor darkGrayColor]];

    UILabel *tempLabel=[[UILabel alloc]initWithFrame:CGRectMake((headerView.frame.size.width/2)-47,-32,300,94)];
    tempLabel.backgroundColor=[UIColor clearColor];
    tempLabel.shadowColor = [UIColor blackColor];
    tempLabel.shadowOffset = CGSizeMake(0,2);
    tempLabel.textColor = [UIColor whiteColor];
    tempLabel.font = [UIFont fontWithName:@"Helvetica" size:17.0];
    tempLabel.font = [UIFont boldSystemFontOfSize:17.0];
    tempLabel.text= [restaurentsNamesArray objectAtIndex:section];

    [headerView addSubview:tempLabel];

    return headerView;
}
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section;
{
    return 35;
}

Like the same way I'm just populating lineName in cell.textLabel

If you want to do more , just create custom tableViewCell and create layout how you want.

that's it.

Cheers.

Answer 2

Use your restaurant array for section

numberOfSectionsInTableView{}

and your "lines": [{}] array for

numberOfRowsInSection{}

You may get better idea from code mentioned below

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number restaurant count
return [restaurantArray count];
}

and for multiple rows considering you have restaurant as object:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of lines count.
return [objRestaurant.Lines count];
}

Answer 3

First of all create an array of Restaurant type an fetch the data from json and add it into an array just like that

var RestaurantArray = [Restaurant]()

for index  in 0..<JSON["data"].count
{
let address = String(JSON["data"][index]["Address"])

            let CityId = JSON["data"][index]["CityId"].int

            let Description = String(JSON["data"][index]["Description"])

            let Name = String(JSON["data"][index]["Name"])
//create an object of Restaurant type and map the data into object and then add it into array that we have created .

var RestaurantModel:Restaurant?
RestaurantModel.address = address
RestaurantModel.cityID =  cityId
RestaurantModel.Description = Description

RestaurantArray.append(RestaurantModel)

}

now use this array in your tableview

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 1
    }

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return RestaurantArray.count
}

I hope this will make a lot of sense to you

Cheers
