iOS中的嵌套JSON解析

Question

I am stuck in understanding this json. Can anyone help me in parsing. I need the value of key "ItemNo".

I could only do:

NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];

NSArray *arr = [[[json objectForKey:@"ShoppingBagRefList"] objectForKey:@"ShoppingBagRef"] objectAtIndex:0];

if you want to access the single string use the following

NSString *ItemNo = json[@"ShoppingBagRefList"][@"ShoppingBagRef"][0][@"BagDetail"][@"ShoppingBag"][@"ShoppingBagSectionList"][@"ShoppingBagSection"][0][@"ShoppingBagItemList"][@"ShoppingBagItem"][0][@"ItemNo"];

NSLog(@"ItemNo == %@",ItemNo);

or alternateway

if you want to access the all string based on ItemNO then use the following

 NSArray *ItemNo = json[@"ShoppingBagRefList"][@"ShoppingBagRef"][0][@"BagDetail"][@"ShoppingBag"][@"ShoppingBagSectionList"][@"ShoppingBagSection"][0][@"ShoppingBagItemList"][@"ShoppingBagItem"];

for (NSDictionary *temp in ItemNo) {

    NSString *getItemNo = temp[@"ItemNo"];
     NSLog(@"ItemNo == %@",getItemNo);
}
