Add data from an array using its value for key to another Array

Question

Hi i have two Arrays one being Parsed Data that has multiple entries at each cell (FolderName & ID) i want this data to be saved into another array like it is stored in the first array

   FilteredData = [[NSMutableArray alloc]initWithArray:[ParsedData ValueForKey:@"FolderName"]];

   SearchData = [[NSMutableArray alloc]initWithArray:FilteredData];

This is what i have been trying, The data Containing a dictionary at each entry is ParsedData, And the Array in which i have to copy these items is SearchData.

The Array (Parsed Data) Containing the dictionary looks like this

 PARSED DATA (
    {
    CreatedBy = 1;
    FolderName = Posteingang;
    ID = 13000;
    ParentID = 0;
},
    {
    CreatedBy = 1;
    FolderName = Freigaben;
    ID = 13001;
    ParentID = 0;
},

From this Array I need to Get the FolderName And the ID and get them in the SearchData Array

SearchData (
    Posteingang;
    13000;     
    Freigaben;
    13001;
)

I hope the question is clear now

enter image description here

this is just copying the foldername to the array whereas i need the ID as well — Vishal

An array can contain one value either folderName or ID. If you need both the values you need nested array or dictionary or even a custom class. In worst use stringWithFormat and append both of them. now tell what you want ? — Anoop Vaidya

check this one,

NSMutableArray *searchData = [NSMutableArray new];
    for(NSDictionary *dict in ParsedDataArray){//here ParsedDataArray  means PARSED DATA array name
        NSDictionary *tempDict=[[NSDictionary alloc]initWithObjectsAndKeys:[dict ValueForKey:@"FolderName"],@"FolderName",[dict ValueForKey:@"ID"],@"ID" nil], 

        [searchData addObject:dict];
    }

It seems like you misspelled the method name, it should be:

dictionaryWithObjectsAndKeys:

Notice the "s" after Object.

I want a dictionary inside an array which contains foldername and id

So you can get it using this:

NSMutableArray *searchData = [NSMutableArray new];
for(NSDictionary *dict in parsedDataArray){
    NSDictionary *tempDict=@{@"FolderName":dict[@"FolderName"], 
                             @"ID":dict[@"ID"]};
    [searchData addObject:tempDict];
}

EDIT:

@[@"key:@"object"] is the new dictionary literal.

If you are using Xcode 4.3 or older need to do as:

NSDictionary *tempDict=@{@"FolderName":dict[@"FolderName"], 
                                 @"ID":dict[@"ID"]};

means,

NSDictionary *tempDict=[NSDictionary dictionaryWithObjectsAndKeys:[dict objectForKey:@"FolderName"], @"FolderName",[dict objectForKey:@"ID"],@"ID", nil];
