creating a dictionary from array

Question

I have an array like this:

(
    "ALAsset - Type:Photo, URLs:assets-library://asset/asset.JPG?id=EF015EF6-FC98-4ACF-9092-AF7E0196A760&ext=JPG",
    "ALAsset - Type:Photo, URLs:assets-library://asset/asset.JPG?id=6FC0C2DC-69BB-4FAD-9709-63E03182BEE1&ext=JPG",
    "ALAsset - Type:Photo, URLs:assets-library://asset/asset.JPG?id=324E4377-0BCD-431C-8A57-535BC0FC44EB&ext=JPG"
)

And am having a hard time figuring out how to create a dictionary/mutable dictionary that will have a key of "urlRep" and also "caption" for each object in the array.

So I want my dictionary to look like this:

(
{
urlRep = 
    "ALAsset - Type:Photo, URLs:assets-library://asset/asset.JPG?id=EF015EF6-FC98-4ACF-9092-AF7E0196A760&ext=JPG",
caption = ""
},

{
urlRep = 
    "ALAsset - Type:Photo, URLs:assets-library://asset/asset.JPG?id=6FC0C2DC-69BB-4FAD-9709-63E03182BEE1&ext=JPG",
caption = ""
}

)

sorry if my formatting is off but that is the basic idea of what Im going for but am failing to achieve

This is pretty elementary stuff. What code do you have so far? — David Snabel-Caunt

Note that you do not (I hope) want your dictionary to look like that, you want your array of dictionaries to look like that. — Hot Licks

This should do the trick:

NSMutableArray *otherArray = [NSMutableArray new];
for (NSString *string in myArray)
{
    [otherArray addObject:@{@"urlRep":string, @"caption":@""}];
}

You are creating another array with a nsdictionary on every entry.

If you want to edit the caption for example for the dictionary at position 0:

[[otherArray objectAtIndex:0] setObject:@"myValue" forKey:@"caption"];

But you will have to create them as NSMutableDictionary then.
