TableViewController not showing json data - iphone

Question

I'm a beginner and I've read everything on StackOverflow about my problem - my app with json data doesn't show anything on TableViewController. I'm probably missing something obvious, but the help is appreciated very very much. (I'm using the latest Xcode 5 DP, if it's important).
TableVC.h
#interface TableVC : UITableViewController <UITableViewDataSource, UITableViewDelegate>
#property (strong, nonatomic) NSDictionary *kinos;
#property (retain, nonatomic) UITableView *tableView;
-(void)fetchKinos;
#end
And the TableVC.m file is
#interface TableVC ()
#end
#implementation TableVC
- (void)viewDidLoad
{
[self fetchKinos];
[self.tableView reloadData];
[super viewDidLoad];
}
-(void)fetchKinos {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://www.adworldmagazine.com/json.json"]];
NSError *error;
_kinos = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
dispatch_async(dispatch_get_main_queue(), ^{
[self.tableView reloadData];
});
});
}
#pragma mark - Table view data source
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return _kinos.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"KinoCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
//[self configureCell:cell atIndexPath:indexPath];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
NSArray *entities = [_kinos objectForKey:#"entities"];
NSDictionary *kino = [entities objectAtIndex:indexPath.row];
NSDictionary *title = [kino objectForKey:#"title"];
NSString *original = [title objectForKey:#"original"];
NSString *ru = [title objectForKey:#"ru"];
cell.textLabel.text = original;
cell.detailTextLabel.text = ru;
return cell;
}
#end

Answer 1

Your JSON response dictionary contains an array of entities whose count needs to be returned from the table view method.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [[self.kinos objectForKey:#"entities"] count];
}
Also, a suggestion, when you declare strong properties, try to access them as self.propertyName instead of accessing the ivar like _propertyName.
Hope that helps!

Answer 2

I accessed your url- http://www.adworldmagazine.com/json.json on my browser.
The response returns a JSON with root: dictionary.
So,
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return _kinos.count;
}
wont work.
Use this instead:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [_kinos objectForKey:#"entities"].count;
}
