JSONデータはそのようなものです...

{"order_list_1":[
{"name":"@SEVEN (7) OCLOCK BLADE PLATINUM","qty":1,"mrp":0.0},
{"name":"ACT 2 POPCORN BUTTER PEPPER","qty":2,"mrp":0.0},
{"name":"ACT 2 POPCORN CHILLY SURPRISE","qty":3,"mrp":0.0},
{"name":"@MAGGI SOUP HOT N SOUR(1 1)","qty":4,"mrp":0.0},
{"name":"ACT 2 POPCORN GOLDEN SIZZLE","qty":5,"mrp":0.0},
{"name":"AMCHUR AAKHA 1kg","qty":6,"mrp":0.0}]

}

json データはコンソールに表示されますが、テーブルビューには表示されません。

ここに私のコードスニペット...

-(void)fetchData{

dispatch_async(bKQueue, ^{
    NSData *data = [NSData dataWithContentsOfURL:latestURL];


    NSLog(@"LatestURL:%@",latestURL);       
    NSError* error=nil;  

    //Creating JSON Object
    NSDictionary *jsonDict= [NSJSONSerialization JSONObjectWithData:data                                                      options:kNilOptions error:&error];



    NSLog(@"JSON = %@", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);

    //NSLog(@"dataaaa :%@",jsonDict);

    //[self performSelectorOnMainThread:@selector(fetchData:) withObject:data waitUntilDone:YES];



    dispatch_async(dispatch_get_main_queue(), ^{

     //[self fetchData:responseData];
     [self.tableView reloadData];
     //NSLog(@"Value :%@",data);
     });




    NSDictionary *statuses=[jsonDict objectForKey:@"order_list_1"];


    NSLog(@"SomeStatus :%@",statuses);

    if (!statuses)
     {
        NSLog(@"Error in Json :%@",error);
     }
    else
    {


        for(NSDictionary *newValu in statuses)
    {

            NSString *name=[newValu objectForKey:@"name"];

            NSString *qty=[newValu objectForKey:@"qty"];

            NSString *mrp=[newValu objectForKey:@"mrp"];

            NSLog(@"Name :%@    Quantity :%@    MRP :%@ ",name,qty,mrp);
        }
    }


});

}

そして、これは私のTableviewコードです..

  • (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ static NSString *CellIdentifier = @"セル";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {



 cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
} 



NSError *error=nil;         
NSDictionary *jsonDict=[NSJSONSerialization JSONObjectWithData:responseData      options:kNilOptions error:&error];         
NSArray *statuses=[jsonDict objectForKey:@"order_list_1"];              
for (int i=0; i<jsonDict.count; i++) {        
    NSDictionary *newDict=[statuses objectAtIndex:i];                 
NSLog(@"name :%@",[newDict valueForKey:@"name"]);    
}
NSDictionary *text=[statuses objectAtIndex:indexPath.row];    
cell.textLabel.text=[text objectForKey:@"name"];    



[self.tableView reloadData];
return cell;

}
