Sprite Kit - how do I access child nodes function/IVARs?

Question

I'm working with tile map using Tiled. I have an object on my map for the player spawn point.

I have been able to spawn the player object. However, I'm at a loss as to how to access the player objects functions or IVARs??

In MyScene:

TileMapLayer *_playerLayer = [[TmxTileMapLayer alloc]
                initWithTmxObjectGroup:[_tileMap groupNamed:@"Spawn"]
                tileSize:_tileMap.tileSize
                gridSize:_bgLayer.gridSize
                objectType:@"Player"];
[_worldNode addChild:_playerLayer];

This will create a player object. The player object has functions that I want to run and IVARs I want to query. Note, some of the functions return values.

Example from the Player object:

- (BOOL)currentWeaponStatus
{
    return _weapon.hidden;
}

So far I think I can access it using:

BOOL weaponHidden = [[_playerLayer childNodeWithName:@"person"] childNodeWithName:@"weapon"].hidden;

But this doesn't seem 'simple'. How do I access the child nodes' functions/IVARs in the _playerLayer?

FYI: I have a weapon node on the player node - this gets added to the tile map layer node.

Thanks for your time. -Shoes

This is what I needed:

Person *player = (Person *)[_playerLayer childNodeWithName:@"person"];
