Question

Very familiar with Android programming, however very new to iOS (and Objective – C).

I am calling a remote php file within my application and (I believe) successfully parsing the JSON results according to my NSLOG results. Example:

2013-01-17 14:24:30.611 JSON TESTING 4[1309:1b03] Deserialized JSON Dictionary = {
products =     (
            {
        BF = "";
        EN = "2342";
        Measure = ft;
        Name = "Brian";
        "Name_id" = 1;
        Home = "New York";
        "DB_id" = 1;
    },
            {
        BF = "";
        EN = "2123";
        Measure = ft;
        Name = "Rex";
        "Name_id" = 3;
        Home = "New York";
        "DB_id" = 5;
    }
);
success = 1;

}

My question lies in how to populate this information into a table view. I can customize a prototype cell, but where do I go from there?

EDIT:

Here is my code for the view setup:

#pragma mark - Table View

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return productArray.count;
    NSLog(@"Number of arrays %u", productArray.count);
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil) 
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
    }


    NSDictionary *productDictionary = [productArray objectAtIndex:indexPath.row];
    cell.textLabel.text = [productDictionary objectForKey:@"BF"];

    return cell;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self launchTest];
}

and my .h file

@interface tpbaMasterViewController : UITableViewController 
{
    NSDictionary *lists;
    NSArray *productArray;
}

- (void) launchTest;

@property (strong, nonatomic) IBOutlet UITableView *tableView;



@end

Answer 1

You access the objects in a NSDictionary using objectForKey methods. For example, to get an NSArray of the products in the dictionary:

NSArray *productArray = [myDictionary objectForKey:@"products"];

Now you have an array with two dictionary objects. For the various UITableViewDataSource methods you can query the array. A couple of examples:

For – tableView:numberOfRowsInSection:, return the number of objects in the array:

`return productArray.count;`

And for tableView:cellForRowAtIndexPath::

NSDictionary *productDictionary = [productArray objectAtIndex:indexPath.row];
    myCell.bfLabel.text = [productDictionary objectForKey:@"BF"];
    myCell.enLabel.text = [productDictionary objectForKey:@"EN"];
   //  continue doing the same for the other product information

Declaring productArray in the .m file as shown below makes it visible within your view controller (assumes productDictionary is a property:

@interface MyCollectionViewController () {
    NSArray *productArray;
}
@end
...
@implementation MyCollectionViewController

    -(void)viewDidLoad{
        [super viewDidLoad];

        productArray = [self.myDictionary objectForKey:@"products"];
    }
...
@end
