我有一个现有的NSDictionary,其中包含:
{
"charts_count" = 2;
"created_at" = "2010-04-12T16:37:32Z";
exchange = NASDAQ;
"followers_count" = 259;
id = 8404;
industry = "<null>";
"messages_count" = 1436;
ric = "GRPN.O";
sector = "<null>";
symbol = GRPN;
title = Groupon;
"updated_at" = "2011-09-05T04:17:56Z";
}
我该如何将这些内容取出并放入一个新的NSMutableDictionary中?
