objective c - iPhone NSArray from Dictionary of Dictionary values -

-

I have a dictionary of dictionaries that is coming back to me in JSON format 

  "Never": {"color": 0, "count": 0, "UID": 32387, "id": 73129, "name": "never"}, "dev": {"color" : ",": ",", "Id": 32387, "id": 72778, "name": "dev"}, "iphone": {"color": 0, "count": 1, "uid" : 32387, id ": 72777," name ":" iphone "}}

I also have an NSArray that has the required ID for an item such as [72777, 7312 9]

What do I need to do, id => no for objects in the array I get a dictionary of. I know that it is possible through the array again, and then it is to loop through the values ​​of checking the dictionaries and values, but it seems that this is a less long

Excuse me, I just want to find my way around the iPhone SDK and learn the purpose and the coco.

First of all, since you have a JSON Using, I hope you have already met and / or, you are open-source projects to parse both JSON in native Coco formations. Returns an idea about how to use the latter to obtain NSDictionary from a JSON string.

The problem then becomes one in finding the values ​​matched in the dictionary. I do not know about a method that you are looking for - cocoa frameworks are very powerful, but they are designed to be very general and flexible. However, it should not be very difficult to put together in many lines ... (Since you are programming on the iPhone, I will use fast calculation to make the code cleaner.) 

 < Code> NSDictionary * jsonDictionary = ... NSDrift * Director; NSArray * Required ID = ... NSMutableDictionary * matches = [NSMutableDictionary dictionary]; For (id key in jsonDictionary) {innerDictionary = [jsonDictionary objectForKey: key]; If the [include the required ID: Object: [internal object fork: @ "id"]]) [with set object: [innerDictionary objectForKey: @ "name"] for that: [innerDictionary objectForKey: @ "id"] ]; }

This code may contain typo, but the concepts should be sound. Also keep in mind that calls [NSMutableDictionary dictionary] to call an autorelase object.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks.

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
