iPhone UIImageView setting UIImages - ios

Question

I'm making a Card game and trying to call UIImages from an object's instance variable to update a UIImageView
I have a Deck object, which has an NSArray instance variable of Card objects.
Each Card object has a few instance variables, one of which is an UIImage that I'm trying to display in a UIImageView....and this is where I'm having a problem
The storyboard isn't displaying the UIImageView and i'm not getting any compile errors
The UIImageView that I'm trying to update is cardDisplay (ViewController.h)
Here's some snippets from my code
ViewController.h
#import "Deck.h"
#import "Card.h"
#interface ViewController : UIViewController
{
UIImageView *cardDisplay;
}
#property (nonatomic, retain) IBOutlet UIImageView *cardDisplay;
#end
ViewController.m
#import "ViewController.h"
#import "Deck.h"
#import "Card.h"
#implementation ViewController
#synthesize cardDisplay;
- (void)viewDidLoad
{
[super viewDidLoad];
Deck *deck = [[Deck alloc]init];
NSLog(#"%#", deck);
for (id cards in deck.cards) {
NSLog(#"%#", cards);
}
self.cardDisplay = [[UIImageView alloc] initWithImage:
[[deck.cards objectAtIndex:0 ] cardImage]];
}
#end
Card.h
#interface Card : NSObject
{
NSString *valueAsString, *suitAsString;
NSInteger faceValue, countValue;
Suit suit;
UIImage *cardImage;
}
#property (nonatomic, retain) NSString *valueAsString;
#property (nonatomic, retain) NSString *suitAsString;
#property (nonatomic) NSInteger faceValue;
#property (nonatomic) NSInteger countValue;
#property (nonatomic) Suit suit;
#property (nonatomic) UIImage *cardImage;
- (id) initWithFaceValue:(NSInteger)aFaceValue countValue:(NSInteger)aCountValue
suit:(Suit)aSuit cardImage:(UIImage*)aCardImage;
#end
Deck.h
#import "Card.h"
#interface Deck : NSObject
{
NSMutableArray *cards;
}
#property(nonatomic, retain)NSMutableArray *cards;
#end
Deck.m
#import "Deck.h"
#import "Card.h"
#implementation Deck
#synthesize cards;
- (id) init
{
if(self = [super init])
{
cards = [[NSMutableArray alloc] init];
NSInteger aCount, picNum = 0;
for(int suit = 0; suit < 4; suit++)
{
for(int face = 1; face < 14; face++, picNum++)
{
if (face > 1 && face < 7)
aCount = 1;
else if (face > 6 && face < 10)
aCount = 0;
else
aCount = -1;
NSString *path = [[NSBundle mainBundle] bundlePath];
NSString *imagePath = [path stringByAppendingPathComponent:
[NSString stringWithFormat:#"/cards/card_%d.png",picNum]];
UIImage *output = [UIImage imageNamed:imagePath];
Card *card = [[Card alloc] initWithFaceValue:(NSInteger)face
countValue:(NSInteger)aCount
suit:(Suit)suit
cardImage:(UIImage *)output];
[cards addObject:card];
}
}
}
return self;
}
#end

This line:
self.cardDisplay = [[UIImageView alloc] initWithImage:
[[deck.cards objectAtIndex:0 ] cardImage]];
should be:
self.cardDisplay.image = [[deck.cards objectAtIndex:0 ] cardImage];
You need to set the image on the image view you created in IB, not create a new one. Doing it this way doesn't keep you from doing what you want with the timer later.
