內部字典這是我的JSON響應如何更換一個NSMutableArray
data = {
Apparels = (
{
"category_id" = 1650002;
"category_name" = Apparels;
"country_id" = 1;
"created_by" = 1;
"created_on" = "2016-03-17 13:29:00";
id = 2;
"is_checked" = 0;
"is_delete" = 1;
"modified_by" = 1;
"modified_on" = "2016-08-26 05:53:21";
"short_name" = UP;
status = 550002;
value = UP;
},
{
"category_id" = 1650002;
"category_name" = Apparels;
"country_id" = 1;
"created_by" = 1;
"created_on" = "2016-03-17 13:29:00";
id = 3;
"is_checked" = 0;
"is_delete" = 1;
"modified_by" = 1;
"modified_on" = "2016-08-26 10:41:12";
"short_name" = "<null>";
status = 550001;
value = MP;
},
{
"category_id" = 1650002;
"category_name" = Apparels;
"country_id" = 1;
"created_by" = 4;
"created_on" = "2016-04-08 12:10:17";
id = 4;
"is_checked" = 0;
"is_delete" = 1;
"modified_by" = 1;
"modified_on" = "2017-03-06 10:35:04";
"short_name" = HR;
status = 550002;
value = Haryana;
},
{
"category_id" = 1650002;
"category_name" = Apparels;
"country_id" = 1;
"created_by" = 4;
"created_on" = "2016-04-08 12:10:36";
id = 5;
"is_checked" = 0;
"is_delete" = 1;
"modified_by" = 1;
"modified_on" = "2016-08-26 05:53:29";
"short_name" = HP;
status = 550002;
value = "Himachal Pardesh";
}
);
};
到目前爲止，我可以這樣造屏。我希望該用戶可以檢查和取消選中產品。爲此，我需要將「is_checked」的值從「0」替換爲「1」。這是我的代碼。

的NSLog返回此：

在此之後，它崩潰的numberOfRowsInSection。
任何幫助，將不勝感激。提前致謝。
