objective c - ObjC: Put logic within a variable, and queue that variable in an array... daydreaming?

Question

I'm trying to translate the following JS code to ObjC; It basically defines a function and store it in an array for later execution:

var logic = function() {
    me.removeNode(node);
}
this.queue.push(logic);

My ObjC port contains the method: -(void)removeNode:(AbstractNode*)node and I'm stuck... I would like to just queue a call to this method using the specified "node" argument...

edit: I'm reading about selectors. It's still blurry, but might help. Somehow. Or not?

Is it even possible, or will I need to find a workaround :-) ? Thanks!

Solution to this thanks to the community:

// Queue declaration
NSMutableArray *IRQ = [[NSMutableArray array] retain];

// Add logic to the queue for delayed execution:
[IRQ addObject:^{ NSLog(@"thanks for the help!"); } ];

// Call later
for (int i = 0; i < [IRQ count]; i++){
     void (^delayedCall)(void) = [IRQ objectAtIndex:i];
     delayedCall();
}

Use a block:

[queue addObject:^{
    [me removeNode:node];
}];

Here's a short introduction to blocks. They are the Objective-C equivalent of anonymous functions.
