I have one NSMutableArray with two fields: name and number. The Name of Array is "Urgency" and it contains :

urgency: "ADMIT",
urgencyId: 5

My question is how can I add only the urgency into the temp array? I dont want to add the urgencyID.

    is it nsmutablearray or nsmutabledictionary? Commented Dec 4, 2013 at 12:33
  • You haven't really explained your problem or your data structure very clearly. Post the code you have so far, it might speak for you Commented Dec 4, 2013 at 12:36
  • possible duplicate of copy NSArray inside an empty NSArray Commented Dec 4, 2013 at 13:05
  • Hi Firdos it is nsmutableaarry Commented Dec 16, 2013 at 12:56

It looks like an NSDictionary or your array contains objects of dictionary with two keys called urgency and urgencyId.

You can get it by [... valueForKey:@"urgency"]

EDIT:

I think this (I tried to replicate what you are saying ) may come helpful for you:

NSString *keyUrgency = @"urgency";
NSString *keyUrgencyId = @"urgencyId";

NSDictionary *u1 = @{keyUrgency: @"u1_urgency",
                     keyUrgencyId: @"u1 id"};

NSDictionary *u2 = @{keyUrgency: @"u2_urgency",
                     keyUrgencyId: @"u2 id"};

NSDictionary *u3 = @{keyUrgency: @"u3_urgency",
                     keyUrgencyId: @"u3 id"};

NSArray *array = @[u1, u2, u3];

NSLog(@"array : %@",array);

//you want only urgencies in array
NSArray *urgencies = [array valueForKey:keyUrgency];
NSLog(@"urgencies : %@",urgencies);

You can hold all values like this in one array.

NSArray *allUrgency = [dict valueForKeyPath:@"urgency"];

If the array contains NSDictionary the result for [dict valueForKeyPath:@"urgency"]; it's NSString not NSArray.
valueForKeyPath:returns id not the NSString
Yes, I agree but for the scenario above urgency: "ADMIT" it's string.
Hi Bhargavi thanx for reply ,But how can i get all the urgency and what is the "dict"?
KeyPath must have a dot in between isnt'it, like @"key.urgency

You can do like follow and that is from : iOS - Make a copy of a array object into another

NSMutableArray *tmp = [[NSMutableArray alloc] init];
 for(NSArray *dim1Array in yourMultidimensionalArray)
 {
    for(id obj in dim1Array)
    {
       if([obj valueForKey:@"urgency"])
       {
          [tmp addObject:dim1Array];
          break; // I assume you only want to add it once
       }
    }
 }
