I have trouble displaying the cards that have been drawn in hand. I can see the cards in text form in "All Output" but they don't show visually. An example of a card's name is "club04", "spades06", "heart13", etc. 11-13 is for Jacks to Kings.
This is part of ViewController.m:
-(void) showHand:(Hand *)hand {
int ypos = 40;
for (int i = 0; i < [hand countCards]; i++) {
Card *card = [hand getCardAtIndex:i];
// UIImage *cardImage = [UIImage imageNamed:@"heart08.png"];
UIImage *cardImage = [UIImage imageNamed:[card filename]];
UIImageView *imageView = [[UIImageView alloc] initWithImage:cardImage];
CGRect arect = CGRectMake((i * 40) + 20, ypos, 71, 96);
imageView.frame = arect;
[self.view addSubview:imageView];
}
}
@end
This is Hand.h
#import <Foundation/Foundation.h>
@class Card;
@interface Hand : NSObject {
}
@property NSMutableArray *cardsInHand;
-(void) addCard:(Card *)card;
-(NSInteger) getPipValue;
-(NSInteger) countCards;
-(Card *) getCardAtIndex:(NSInteger) index;
@end
This is Hand.m
#import "Hand.h"
#import "Card.h"
@implementation Hand
- (id) init {
if (self = [super init]){
self.cardsInHand = [[NSMutableArray alloc] initWithCapacity:6];
}
return (self);
}
- (NSInteger)countCards {
return ([self.cardsInHand count]);
}
- (void)addCard:(Card *)card {
[self.cardsInHand addObject:card];
}
- (NSInteger)getPipValue {
NSInteger aValue = 0;
for (Card *tCard in self.cardsInHand) {
aValue = aValue + [tCard pipValue];
}
return aValue;
}
- (Card *)getCardAtIndex:(NSInteger)index {
return ([self.cardsInHand objectAtIndex:index]);
}
- (NSString *)description {
return [NSString stringWithFormat:@"cards in hand : %@", self.cardsInHand];
}
@end
Funny thing is that when I type manually a single card I get to see the cards. I just see 6 times the same card.
But "All Output" displays what I need to see.
Example:
2013-04-21 19:18:41.025 blackjack[1395:c07] Dealer:cards in hand : (
"Club 5 (pipValue = 0)",
"Spade Jack (pipValue = 1)",
"Club 8 (pipValue = 0)",
"Spade Queen (pipValue = 1)",
"Diamond King (pipValue = 1)",
"Heart 7 (pipValue = 0)"
)
this is the part that puts the cards in the hands and table:
-(id) init {
if ((self = [super init])){
_deck = [[Deck alloc] init];
_playerHand = [[Hand alloc] init];
_dealerHand = [[Hand alloc] init];
_table = [[Table alloc] init];
}
return (self);
}
-(void)setup
{
//deal cards
[_playerHand addCard:[_deck drawCard]];
[_dealerHand addCard:[_deck drawCard]];
[_playerHand addCard:[_deck drawCard]];
[_dealerHand addCard:[_deck drawCard]];
[_playerHand addCard:[_deck drawCard]];
[_dealerHand addCard:[_deck drawCard]];
[_playerHand addCard:[_deck drawCard]];
[_dealerHand addCard:[_deck drawCard]];
[_playerHand addCard:[_deck drawCard]];
[_dealerHand addCard:[_deck drawCard]];
[_playerHand addCard:[_deck drawCard]];
[_dealerHand addCard:[_deck drawCard]];
[_table addCard:[_deck drawCard]];
[_table addCard:[_deck drawCard]];
[_table addCard:[_deck drawCard]];
[_table addCard:[_deck drawCard]];
this is card.m:
#import "Card.h"
@implementation Card
@synthesize suit = _suit, cardNumber=_cardNumber;
-(id) initWithCardNumber:(NSInteger)aCardNumber suit:(Suit)aSuit {
if (self = [super init])
{
_suit = aSuit;
_cardNumber = aCardNumber;
}
return self;
}
