//Card.h

#import <Foundation/NSObject.h>
//#import <Foundation/Foundation.h>
//#import Foundation;

@interface Card : NSObject
//默认object-c会自动创建getter与setter
@property {strong ，nonatomic} NSString * contents;
@property {nonatomic} BOOL chosen;
@property {nonatomic} BOOL matched;
//方法默认命名 getter->matched setter->setMatched 
//方法重命名 @property {nonatomic,getter=isMatched} BOOL matched;

- (int ) match:(Card *)card; 
- (int ) matchs:(NSArray *)card; 

@end

//Card.m

#import "Card.h"

//私有属性或方法的声明，主要用于属性
@interface Card()

@end


//灭有synthsize你将无法创建card实例，而且它没有名，你无法再getter和setter中引用它
//实际上这些代码是看不到的，object-c会自动创建
@synthesize contents = _contents;
@synthesize chosen = _chosen;
@synthesize matched = _matched;
//- (NNString *)contents 是一个方法声明
// - 表示这是一个方法
- (NNString *)contents{
    return _contents;
}

- (void)setContents:(NNString *contents){
     _contents = contents;
 }

- (BOOL) chosen
{
    return _chosen;
}

- (void) setChosen:(BOOL chosen){
    _chosen = chosen;
}

- (BOOL) matched{
    return _matched; 
}

-(void )setMatched:(BOOL matched){
    _matched = matched;
}

@implementation Card


- (int )match:(Card *)card{
    int score = 0;

    if([card.contents isEqualToString:self.contents]){
        score=1;
    }

    return score;
}

- (int )matchs:(NSArray *)otherCards{
    int score = 0;


    for(Card * card in otherCards){
