Question

我刚刚制作了一个“应用程序”，它只是在命令行(outpot)中打印一些东西这是一个例子 -

代码:

卡片.h:

#import <Foundation/Foundation.h>
@interface Card : NSObject {
    int CardValue;
    int CardType;
}
@property int CardValue,CardType;
@end

卡片.m:

#import <Foundation/Foundation.h>

Deck.h:

#import <Foundation/Foundation.h>
#import "Card.h"

-(void)createDeck;
-(void)createFullDeck : (Deck *) TheDeck;
-(void)insertToDeck : (Card *) TheCard;
@end

甲板.m:

#import "Deck.h"
#include <stdlib.h> 
@implementation Deck
@synthesize Deck1, Deck2, Deck3, Deck4, Deck5;
-(void)createDeck{

        [Deck4 removeObjectAtIndex:randomValue];
    }
    MethodCard.CardType = randomType+1;
    return MethodCard;

游戏.h:

#import <Foundation/Foundation.h>
#import "Deck.h"
@interface Game : NSObject

-(void)StartNewGame : (Deck *) TheDeck : (Game *) TheGame;
-(BOOL)GetDecision : (int) TheNumber;
-(void)CheckHiOrLo : (int) FirstNumber : (Deck *) TheDeck : (Game *) TheGame;

游戏.m:

#import "Game.h"
@implementation Game
-(void)StartNewGame : TheDeck : (Game *) TheGame{
    NSLog(@"Welcome to the game High-Low!");
    [TheDeck createDeck];
    [TheDeck createFullDeck:TheDeck];
    Card *TheCard = [[Card alloc]init];
    TheCard = [TheDeck DrawCard];
    [TheGame CheckHiOrLo: TheCard.CardValue : TheDeck : TheGame];
    }
-(BOOL)GetDecision : (int) TheNumber{
    int userNum=0;
    NSLog(@"The Card is %i\nif you think the next Card is going to be higher - type 1.\nif you think the next Card is going to be lower - type 0.", TheNumber);
    scanf("%i", &userNum);
    if(userNum==1)

    if(userNum==0)

    TheCard = [TheDeck DrawCard];
    BOOL Decision = [TheGame GetDecision:FirstNumber];
    if(FirstNumber>TheCard.CardValue){
        if(Decision==YES){
            NSLog(@"%i", TheCard.CardValue);
            NSLog(@"GameOver");
        }
        if(Decision==NO){
            NSLog(@"%i \nCorrect, Next Card", TheCard.CardValue);
            [TheGame CheckHiOrLo: TheCard.CardValue : TheDeck : TheGame];
        }
    }
    if(FirstNumber<=TheCard.CardValue){
        if(Decision==YES){
            NSLog(@"%i \nCorrect, Next Card", TheCard.CardValue);
            [TheGame CheckHiOrLo: TheCard.CardValue : TheDeck : TheGame];
        }
        if(Decision==NO){
            NSLog(@"%i", TheCard.CardValue);
            NSLog(@"GameOver");
        }
    }
}
@end

所以现在我尝试为此制作一个 iPhone 应用程序，所以我制作了一个新的 iPhone 项目，将 Card、Deck 和游戏类移至 iPhone 项目，并制作了一个高按钮、一个低按钮和一个开始按钮建立一个新的平台。

现在我该怎么做，当我点击开始按钮时，它会触发 Deck 类中的方法 createDeck 和 CreateFullDeck？

Answer 1

首先你要在你的头文件中使 Deck 成为声明的对象，比方说你的 UIViewController，确保你 #import Deck.h.

#import "Deck.h"

@interface MainViewController: UIViewController

      Deck *deck;
@end

现在，您可以在 MainViewController 的 -viewDidLoad 方法中初始化您的 deck

-(void)viewDidLoad {

    [super viewDidLoad];

     deck = [[Deck alloc] init];
 }

在您的按钮操作中，您将创建完整的牌组。假设这是一个连接到 Interface Builder 中的 UIButton 的 IBAction；

 -(IBAction)onCreateClicked:(id)sender {

      [deck createDeck:deck];
      // You now created your deck of cards.
   }

希望对您有所帮助!

编辑:在进一步调查您的代码后，您的代码有很多问题，但上面的示例将按照您的要求执行。
