Is there any way to do addObjectFromArray:atIndex:?
I have 2 NSMutableArrays. Lets say 1st array is array1 and the 2nd is array2. They ar filled with values. And I need to add item from array1 at index 3 to array2. Is it possible?

Does the index in array2 matter? Meaning: Do you want to have the object in array2 at the same index as in array1 (if possible)?Orangenhain– Orangenhain2012-07-10 09:05:04 +00:00Commented Jul 10, 2012 at 9:05

Retrieve the object using:
[array1 objectAtIndex:3]
Add the object using:
[array2 addObject:theObject];
In other words, the following adds object 3 from array1 to array2:
[array2 addObject:[array1 objectAtIndex:3]];

You need to break this into two steps, like this:
[array2 addObject: [array1 objectAtIndex: index3]];

We have addObjectsFromArray: method it means,adds the objects contained in another given array to the end of the receiving array’s content.
But we don't have addObjectFromArray:atIndex: method. For getting your results, you can use methods what NSMutableArray class contains.
[array2 addObject: [array1 objectAtIndex: index3]];
Here we can use two methods addObject: and objectAtIndex:. For more details, use this link.
