Question

I have a NSMutableArray in the didSelectRowAtIndexPath: method:

[self.somethingSelected addObject:[self.arrayFromTable objectAtIndex:indexPath.row]];

The output of this self.somethingSelected (an NSMutableArray) is the following. How do I access just the id value from the following output?

I want self.somethingSelected to store “11,9,21…” and none of the other values like title, etc…

(
    {
        id = 11;
        title = Title0;
    },
    {
        id = 9;
        title = Title1;
    },
    {
        id = 21;
        title = Title2;
    },
)

I tried:

[self.somethingSelected addObject:[self.arrayFromTable objectAtIndex:indexPath.row] objectForKey:@"id"];

but I think I’m mixing up NSDictionary and NSMutableArray, perhaps.

Answer 1

if arrayFromTable holds NSDictionaries than what you tried should work, but you are missing a ‘[‘ & ‘]’. it should be:

    [self.somethingSelected addObject:[[self.arrayFromTable objectAtIndex:indexPath.row] objectForKey:@"id"]];
