iphone - NSMutableArray 的大小(内存)是多少？

Question

我正在解析 json 数据，并将它们存储到 NSMutableArray 中。对于每个数据，参数格式如下，

{
    "id":"6",
    "username":"biju",
    "password":"biju123",
    "usertype":"2",
    "first_name":"biju",
    "last_name":null,
    "email":"b@b.com",
    "blocked":"N",
    "created":"2012-11-02 16:03:19",
    "image":"http:\/\/192.168.1.254\/eatthos\/assets\/upload\/users\/1351852399_thumb.jpg","thumb_image":"1351852399_thumb.jpg",
    "menu_image":"0",
    "thumb_menu_image":"0",
    "city":"njdfh",
    "favorite_food":"kafh",
    "favorite_restaurant":"kafdhj",
    "phone_number":"0",
    "description":"0",
    "token":"Dwx0DG",
    "fb_unique_id":null,
    "account_type":"normal",
    "twitter_id":null,
    "followers":"5",
    "follow":"N"
}

我正在解析大约 100K 的数据，该数组的大小(内存)是多少？如果我将它用于 iphone 应用程序，是否会出现内存问题？

Answer 1

您可以尝试使用以下代码找出数组的大小:

size_t total;
 id obj;
 for (obj in array)
 {
    total += class_getInstanceSize([obj class]);
 }

 NSLog(@"Array size : %ld",total); //This will return you size in bytes

你需要做的:#import <objc/runtime.h>
