Displaying to a UIImageView from an object instance

[NickFalk]

Hi there. I'm finally finding the time to try my hand at some baby steps* in iPhone programming. I am currently working on a very simple dungeon crawler as this is something I've made a few times before on other platforms and in other languages.

I have a ViewController named "DungeonViewController" and I have a class named "Room". The idea is to have an instance of the Room.class displaying an image (or rather two) to an UIImageView in the DungeonView.xib.

I have made an object of the type Room in the xib-file and connected the outlet "floor" to the UIImageView in question. It is (obviously) not working however. Here are some code snippets:

Room.h

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface Room : NSObject {
	IBOutlet UIImageView *floor;
}
@property (nonatomic, retain) UIImageView *floor;
-(void) displayRoomFloor:(id)sender;
@end

Room.m

#import "Room.h"
@implementation Room
@synthesize floor;

-(void)displayRoomFloor:(id)sender
{
	NSLog(@"displayRoomFloor");
			floor.animationImages = [NSArray arrayWithObjects: [UIImage imageNamed:@"floor1.png"],[UIImage imageNamed:@"floor2.png"], nil];
			floor.animationDuration = 0.2;
			floor.animationRepeatCount = 0;
		[floor startAnimating];
}@end

Now, the animation bit should work just fine as it does when it is included directly in my DungeonViewController/viewDidLoad. At the moment I'm trying to achieve the same thing by calling an instance of room like below:

-(void)viewDidLoad {
    [super viewDidLoad];	
	room = [[[Room alloc] init] autorelease];
		[room displayRoomFloor:self];
}

I know from the console that the call to the instance method is achieved but it is not displaying anything (or at least not doing so in a visible manner).

I believe I might have some misconception about the right way to hook this kind of stuff up? My idea is to use the Room-class to display graphical details for each room in a dungeon and as such it made sense to me that each room should actually be an object...

Anyone?
Anyone, actually understand what I'm writing right now? Not sure I do. Time to open up another bottle of beer. It's the best thing that doesn't help.



*I'm not quite sure how I manage to makes steps of any sort with my hands. Ah, the blessing of mixed metaphors...

i would also like to know the solution to this, as i'm in the process of teaching myself how to not be a super noob.

for example, i do'nt know why his [room displayRoomFloor:self] takes in a parameter "self"

... bahh...
