如何在使用 JSON 响应时从数组中获取包含对象和数组中已有对象的值？
how to gat a value from an array which contain in an object and object already in an array while using json response?
问：
[
{
"result": 1,
"max_qty": "10",
"msg": [
{
"product_id": "39",
"product_name": "Cabbage",
"product_price": "18",
"product_image": "product/39.jpg",
"product_description": "Fresh Cabbage",
"product_category": "1",
"product_qty": [
{
"quantity_id": "3",
"quantity_name": "500 gm",
"value": "500",
"quantity_status": "1"
},
{
"quantity_id": "4",
"quantity_name": "1 Kg",
"value": "1000",
"quantity_status": "1"
}
在这个“msg”中，它是一个数组，包含对象形式的值，但“product_qty”又是一个位于对象下的数组，现在我该如何获取product_qty ]1 的元素值

您需要像这样获取键值：
NSDictionary *dictProducts = array[0]; // From Main Array.
NSArray *allProduct = dictProducts[@"msg"]; // Form Dictionary.
NSDictionary *firstProduct = allProduct[0];
NSLog(@"Product Qty : %@", firstProduct[@"product_qty"]); // Here you can get product_qty array.
希望这会有所帮助。

Updated Code:
NSDictionary *mainDic = [arrResponse objectAtIndex:0];
NSArray *arrMsg = [mainDic valueForKey:@"msg"];
for (NSDictionary *dicSub in arrMsg) {
NSArray *arrProdQuality = [dicSub valueForKey:@"product_qty"];
for (NSDictionary *dicQuality in arrProdQuality) {
NSLog(@"quantity_name %@",[dicQuality valueForKey:@"quantity_name"]);
}
}

刚刚用过这个
if（[数组包含对象字典]）
{ }

{already in your arraynot in your array
}
