NSDictionary with keys issue

What would be the best way to pull information from a dictionary if I only wanted some of the information?

Below is an example of the information being pulled back. I only need the description.

2014-06-08 15:37:15.399 TC[1381:4207] (
        {
        dateAdded = "2014-04-21T13:22:15Z";
        id = 7473;
        type = "[Acme] Assigned To";
        value = "Analyst";
    },
        {
        dateAdded = "2014-04-21T13:21:44Z";
        id = 7472;
        type = "[Acme] Date Briefed ";
        value = "04-26-2014 00:00 UTC";
    },
        {
        dateAdded = "2014-04-21T13:21:29Z";
        id = 7471;
        type = "Description"; 
        value = "This is the description"; //I want this information!
    },

For sure! Try:

for (NSDictionary *myDict in myArray) {
    NSString *myString = [myDict valueForKey:@"type"];
    if ([myString isEqualToString:@"Description"]) {
        NSLog(@"%@", [myDict valueForKey:@"value"]);
    }
}

Or objectForKey

Yeah, It's not working 

2014-06-08 20:32:15.553 App[3328:162915] LabelValue is =====> (null)

Problem is the keys are all the same, but the values are different. It has 4+ keys that are all named value. I just need the one that has the description. Not sure if its possible.

It almost looks like you have an array of dictionaries? If that is the case then it would be more like:

NSDictionary *myDict = [myArray objectAtIndex:2];

Then

[myDict valueForKey:@"value"];

To get the value specified in your original post.

right, problem is its NEVER in the same order, and some of them don't have a description. :(

Then there is a problem when you are creating the array, and when you say description, do you mean the value for a key?

Yeah, I need the pull the Key "value" that holds the description.

Is is possible to filter on the other Keys to figure out what value to pull? 

{
        dateAdded = "2014-04-21T13:21:29Z";
        id = 7471;
        type = "Description"; //This tells me that the value will hold the description I am looking for. 
        value = "This is the description"; //I want this information!
    },

dateAdded = "2014-04-21T13:21:44Z";
        id = 7472;
        type = "[Acme] Date Briefed ";
        value = "04-26-2014 00:00 UTC"; // I don't need or want this value key 
    },

Thanks for your time btw. Also if you want to see it just shoot me an email I'll share the project with you over a private github. Aaron at Mav3r1ck.com
