Question

我需要根据来自Web服务的数组长度动态创建uilabel。请看我的网络服务结构。

{"result":"Successful","data":[{"price":"100.00","packs":"Bio Bags","pack_id":"1","products":[{"quantity":"15","image":"1454651885ECOWGBS_03.jpg"},{"quantity":"15","image":"1454652017ECOWGBM_03.jpg"},{"quantity":"15","image":"1454652132ECOWGBL_02.jpg"}]},{"price":"200.00","packs":"Party Pack","pack_id":"2","products":[{"quantity":"50","image":"1454589144USI_6819.jpg"},{"quantity":"50","image":"1454587252ecow240b_01.jpg"},{"quantity":"50","image":"1454499020ecow10rp_01.jpg"}]},{"price":"300.00","packs":"Travel Pack","pack_id":"3","products":[{"quantity":"25","image":"1454589144USI_6819.jpg"},{"quantity":"25","image":"1454588615ecow103crp_01.jpg"},{"quantity":"25","image":"1454588259ecowclam_01.jpg"}]},{"price":"400.00","packs":"Kids Pack","pack_id":"4","products":[{"quantity":"25","image":"1454499251ecow6rp_01.jpg"},{"quantity":"25","image":"1454588417ecow5ct_01.jpg"},{"quantity":"25","image":"1454587802ecow340b_01.jpg"}]}]}

我需要在uilabel和uiimage上设置数量名称和图像以及uicollectionview cell.sometime数量名称可以是3有时它可以是20.现在写我将其添加到stoically。请看下面的代码。

-(void)connectionDidFinishLoading:(NSURLConnection *)connection

{ [UIApplication sharedApplication] .networkActivityIndicatorVisible = NO; NSArray * dataarray = [[NSJSONSerialization JSONObjectWithData：数据选项：0错误：无] objectForKey：@＆＃34;数据＆＃34;];

[packdetail removeAllObjects];


for (NSDictionary *tmp in dataarray)
{
    NSMutableDictionary *temp = [NSMutableDictionary new];
    [temp setObject:[tmp objectForKey:@"packs"] forKey:@"packs"];
    [temp setObject:[tmp objectForKey:@"pack_id"] forKey:@"pack_id"];

    [packdetail addObject:temp];

    NSArray *productarray = [tmp objectForKey:@"products"];
    NSLog(@"products %@", productarray);

    for (NSDictionary *product in productarray) {

        NSMutableDictionary *temp2 =[NSMutableDictionary new];
        [temp2 setObject:[product objectForKey:@"quantity"]forKey:@"quantity"];
         NSLog(@"temp2 %@", temp2);

        [quantity addObject:temp2];
    }


}
if (packdetail)
{
    [_subscriptioncollectionview reloadData];
          }


      }














  - (NSInteger)collectionView:(UICollectionView *)collectionView  numberOfItemsInSection:(NSInteger)section{

return [packdetail count];
    }

   -(UICollectionViewCell*)collectionView:(UICollectionView  *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{

     SubscriptionCell *cell = (SubscriptionCell*)[collectionView  dequeueReusableCellWithReuseIdentifier:@"cell" forIndexPath:indexPath];



cell.packname.text = [[packdetail objectAtIndex:indexPath.row] objectForKey:@"packs"];
cell.productname.text = [[quantity objectAtIndex:indexPath.row] objectForKey:@"quantity"];



return cell;

  }

请给我一些基本想法，这样我就能继续前进。
