Question

i have the following JSON Data, which is a respond from my Webservice.

     {"d": [{"raumKlassenObject":"Telepresenzraum"},
{"raumKlassenObject":"Besprechungsraum"},
{"raumKlassenObject":"Videokonferenzraum"},
{"raumKlassenObject":"IT-Schulungsraum"},
{"raumKlassenObject":"Konferenzraum"}]}

How can i display the Data Telepresenzraum, Besprechungsraum etc… in a TableView.

Heres my Code so far.

    - (void)viewDidLoad
{
    [super viewDidLoad];

    dic = [NSJSONSerialization JSONObjectWithData:result options:kNilOptions error:nil];
    array = [dic allKeys];

}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

    // Return the number of rows in the section.
    return array.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

   cell.textLabel.text=[NSString stringWithFormat:@"%@",[dic objectForKey:@"d"]];    



return cell;
}

If i do it like that the output in the Tableview is

 [{"raumKlassenObject":"Telepresenzraum"},{"raumKlassenObject":"Besprechungsraum"},{"raumKlassenObject":"Videokonferenzraum"},{"raumKlassenObject":"IT-Schulungsraum"},{"raumKlassenObject":"Konferenzraum"}]

I dont know how to display only Telepresenzraum, Besprechungsraum, Videokonferenzraum etc.. in tableview rows.

Thx for help.

Answer 1

You top level dictionary only has one key,”d”, so array.count will be 1 and the [dic objectForKey:@”d”] will be the whole array of dictionaries.

So, to fix this redefine array as:

array = [[dic valueForKey:@"d"] valueForKey:@"raumKlassenObject"];

This should give you an array of all the values for that key. Then, replace the first line below with the second:

cell.textLabel.text= [NSString stringWithFormat:@"%@",[dic objectForKey:@"d"]]; 
cell.textLabel.text= [array objectAtIndex:indexPath.row];
