私のカードマッチングゲームでは：
-特定のインデックスでめくられたカードをチェックする方法があります。基本的には、アプリ内のロジック全体です。
-一致を確認する別の方法があります。
ここで、ユーザーが基本モード (2 カード) ではなく「3」カードのモードを変更したことをコントローラーに伝えるスイッチ ボタンをビュー コントローラーに作成しました。
私の問題は、2 つ以上の一致がある場合に一致する方法をチェックインするようにコントローラーに指示する方法です..それは私を夢中にさせています.これを理解するのを手伝ってください.
また、コントローラーには、一致するカードをフェードアウトさせる updateUI メソッドがあるため、同じように動作することを確認する必要があります。
次のコードは、flipCardAtIndex メソッドを示しており、メソッドとビュー コントローラーが同じ順序で一致しています。
CardMatchingGame.m (最後のメソッドは flipCardAtIndex):
#import "CardMatchingGame.h"
#import "PlayingCardsDeck.h"
@interface CardMatchingGame()
@property (readwrite, nonatomic) int score;
@property (strong, nonatomic) NSMutableArray *cards;
@property (strong, nonatomic) NSString *notification;
@end
@implementation CardMatchingGame
-(NSMutableArray *) cards {
if (!_cards) _cards = [[NSMutableArray alloc] init];
return _cards;
}
-(id)initWithCardCount:(NSUInteger)count usingDeck:(Deck *)deck {
self = [super init];
if (self) {
for (int i = 0; i < count; i++) {
Card *card = [deck drawRandonCard];
if (!card) {
self = nil;
} else {
self.cards[i] = card;
}
}
}
return self;
}
-(Card *) cardAtIndex:(NSUInteger)index {
return (index < self.cards.count) ? self.cards[index] : nil;
}
#define FLIP_COST 1
#define MISMATCH_PENALTY 2
#define BONUS 4
-(void) flipCardAtIndex:(NSUInteger)index {
Card *card = [self cardAtIndex:index];
if (!card.isUnplayable) {
if (!card.isFaceUp) {
for (Card *otherCard in self.cards) {
if (otherCard.isFaceUp && !otherCard.isUnplayable) {
NSMutableArray *myCards = [[NSMutableArray alloc] init];
[myCards addObject:otherCard];
int matchScore = [card match:myCards];
if (matchScore) {
otherCard.unplayble = YES;
card.unplayble = YES;
self.notification = [NSString stringWithFormat:@"%@ & %@ match!", card.contents, otherCard.contents];
self.score += matchScore * BONUS;
} else {
otherCard.faceUp = NO;
self.score -= MISMATCH_PENALTY;
self.notification = [NSString stringWithFormat:@"%@ did not matched to %@", card.contents, otherCard.contents];
}
break;
}
}
self.score -= FLIP_COST;
}
card.faceUp = !card.isFaceUp;
}
}
@end
PlayingCards.m (最初のメソッドのみ、マッチング メソッド) :
#import "PlayingCards.h"
@implementation PlayingCards
@synthesize suit = _suit;
//overriding the :match method of cards to give different acore if its only a suit match or a number match
-(int)match:(NSArray *)cardToMatch {
int score = 0;
for (int i = 0; i < cardToMatch.count; i++) {
PlayingCards *nextCard = cardToMatch[i];
if ([nextCard.suit isEqualToString:self.suit]) {
score += 1;
} else if (nextCard.rank == self.rank) {
score += 4;
}
}
return score;
}
私のView Controller（最後の方法はスイッチボタン用のものです）：
