something like:

Setting the property by its synthesized setter is shorter (and, to my eyes, cleaner to read and comprehend):

[[myArray objectAtIndex:0] setIntProperty:12345];

First, you will need to store the ID in a variable, like

(id) myObject = [myArray objectAtIndex:0];

Then you can manipulate it:

myObject.intProperty = 12345;

And store it again:

[myArray removeObjectAtIndex:0]; // Remove it before setting it again
[myArray insertObject:myObject atIndex:0];

EDIT: Or you could use Jacob's way, which is much better :)

You need to cast the object first.

((MyObjectType *) [myArray objectAtIndex:0]).intProperty = 12345;
