Je reçois l'erreur incompatible pointer types assigning to Deck *__strong from PlayCards *
Obtenir une erreur sur mon (premier) CardGameViewController
Et je ne sais pas pourquoi ça. Son dans la première méthode mis en œuvre (plate-forme):
#import "CardGameViewController.h"
#import "PlayingCards.h"
@interface CardGameViewController()
@property (weak, nonatomic) IBOutlet UILabel *cardLabel;
@property (nonatomic) NSUInteger flipsCount;
@property (strong, nonatomic) Deck *deck;
@end
@implementation CardGameViewController
-(Deck *) deck {
if (!_deck) _deck = [[PlayingCards alloc] init];
return _deck;
}
-(void) setFlipsCount:(NSUInteger)flipsCount {
_flipsCount = flipsCount;
self.cardLabel.text = [NSString stringWithFormat:@"Flips:%d", self.flipsCount];
}
- (IBAction)flipCard:(UIButton *)sender {
sender.selected = !sender.isSelected;
self.flipsCount++;
}
@end
Ceci est le fichier d'en-tête (rien qui se passe ici):
#import <UIKit/UIKit.h>
//#import "Card.h"
//#import "Deck.h"
//#import "PlayingCards.h"
@interface CardGameViewController : UIViewController
@end
Et la classe carte à jouer héritant de la classe de plate-forme ..
c'est le PlayingCards.m
#import "PlayingCards.h"
@implementation PlayingCards
@synthesize suit = _suit;
//modifying the contents getter so it will return array with the ranks and rank+suit
-(NSString *) contents {
NSArray *cardsRank = [PlayingCards rankStrings];
return [cardsRank[self.rank] stringByAppendingString:self.suit];
}
//creating a method to make sure we get validated suits
+(NSArray *) validSuit {
return @[@"♠",@"♣",@"♥",@"♦"];
}
//creating calss method to validate the rank
+(NSArray *) rankStrings {
return @[@"?",@"A",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",@"J",@"Q",@"K"];
}
//creating a new setter for suit to make sure we get the valitated suits, uding the validateSuit method
-(void) setSuit:(NSString *)suit {
if ([[PlayingCards validSuit] containsObject:suit]) {
_suit = suit;
}
}
//creating new getter for suit to make sure its not empty
-(NSString *) suit {
return _suit? _suit: @"?";
}
//creating a class method to make sure when user set the rank he will will
+(NSUInteger) maxRank {
return [self rankStrings].count - 1;
}
//creating a new setter to the renk to make sure the rank is validates
-(void) setRank:(NSUInteger)rank {
if (rank <= [PlayingCards maxRank]) {
_rank = rank;
}
}
@end
PlayingCards.h
#import "Card.h"
#import "Deck.h"
@interface PlayingCards : Card
@property (strong, nonatomic) NSString *suit;
@property (nonatomic) NSUInteger rank;
+(NSArray *) validSuit;

La synthèse est-elle manquante ou l'avez-vous simplement omise? – cardmagik
À quoi ressemble l'initialiseur de PlayingCards? – CodaFi
