我无法显示手中已抽出的牌。我可以看到文本形式的卡片，"All Output"但它们没有直观地显示。牌名的一个例子是"club04", "spades06","heart13"等。11-13 代表 Jacks to Kings。

这是一部分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

这是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

这是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

有趣的是，当我手动输入一张卡片时，我会看到卡片。我只看到同一张卡片的 6 次。

但"All Output"显示我需要看到的。例子：

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)"
)

这是将牌放在手中和桌子上的部分：

-(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]];

这是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;
}

/*
 ** pipValue will return the pipValue of a card.
 **          2 to 9 will return 0.
 **          an ace will always return 1
 **          Jack, Queen and King will always return 1.
 **          2 of Clubs will return 1
 **          10 of diamonds will return 2
 */
-(NSInteger) pipValue {

if (_suit==Diamonds && _cardNumber==10)
    return (2);
else if (_cardNumber>=10)
    return (1);
else if (_cardNumber==1)
    return (1);
else if (_suit==Clubs && _cardNumber==2)
    return (1);
else
    return (0);

}

/*
 ** private method
 ** returns the suit as a String
 */
-(NSString *) suitAsString{
switch (_suit) {
    case Hearts:
        return @"Heart ";
        break;
    case Spades:
        return @"Spade ";
        break;
    case Diamonds:
        return @"Diamond ";
        break;
    case Clubs:
        return @"Club ";
        break;
    default:
        return nil;
        break;
}
}

/*
 ** private method
 ** returns the cardNumber as a String
 */
-(NSString *) cardNumberAsString{
switch (_cardNumber) {
    case 1:
        return @"Ace";
        break;
    case 11:
        return @"Jack";
        break;
    case 12:
        return @"Queen";
        break;
    case 13:
        return @"King";
        break;
    default:
        return [NSString stringWithFormat:@"%d", _cardNumber];
        break;
}
}

-(NSString *) filename{
return ([NSString stringWithFormat:@"%@%02d.png", [self suitAsString], [self cardNumber]]);
}

-(NSString *) description {
return [NSString stringWithFormat:@"%@ %@ (pipValue = %d)", [self suitAsString], [self cardNumberAsString], [self pipValue]];
}


@end

还有deck.m：

#import "Deck.h"
#import "Card.h"

@implementation Deck

-(id) init {
if (self = [super init])
{
    cards = [[NSMutableArray alloc] init];

    for (int suit = 0; suit <= 3; suit++)
    {
        for (int cardNumber = 1; cardNumber <= 13; cardNumber++)
        {
            [cards addObject:[[Card alloc] initWithCardNumber:cardNumber suit:suit]];
        }
    }

    [self shuffle];
}
return self;
}

-(Card *) drawCard {
if ([cards count]>0)
{
    Card* tCard = [cards lastObject];
    [cards removeLastObject];
    return tCard;
}
return nil;
}

-(void) shuffle {
NSUInteger count = [cards count];
for (NSUInteger i = 0; i < count; ++i) {
    // Select a random element between i and end of array to swap with.
    int nElements = count - i;
    int n = (arc4random() % nElements) + i;
    [cards exchangeObjectAtIndex:i withObjectAtIndex:n];
}
}

- (NSString *)description{
return [NSString stringWithFormat:@"Deck : %@", cards];
}

@end

如果@"heart08.png"有效而[card filename]无效，那么您应该首先打印出[card filename]返回的内容。

什么是“所有输出”？

在您的代码中，我认为您使用的是随机函数，这是随机函数的问题。它像一个池子一样工作，如果它得到相同的结果，它会使用一些时间间隔，它会显示相同的结果。您应该通过当前时间的 mili 部分来获取随机值 n 这个问题将被解决
