Cocos2d 게임에서 사용자 설정을 효과적으로 저장하는 방법

Question

현재 Cocos2d 게임의 설정을 저장하는 기능을 가지고 있으며 사용하는 방법은 XML 파서입니다.

우선 NSUserDefaults를 다음과 같이 사용하는 것이 더 좋습니까?

EDIT : XML PARSER가 끝까지 건너 뛰는 지 이미 알고 있다면 미리 작성해 두십시오.

#import <Foundation/Foundation.h> 

@interface GlobalSettings : NSObject { 

// Declare variables with an underscore in front, for example: 
int _currency; 
BOOL _BankerBossDefeated; 
BOOL _BabyBossDefeated; 
BOOL _DuckBossDefeated; 
BOOL _BaseBallBossDefeated; 
BOOL _NewtonBossDefeated; 

BOOL _CatchExtender; 
BOOL _CatchExtenderEnabled; 
BOOL _SpeedBoost; 
BOOL _SpeedBoostEnabled; 
} 

// Declare your variable properties without an underscore, for example: 
@property (nonatomic, assign) int currency; 
@property (nonatomic, assign) BOOL BankerBossDefeated; 
@property (nonatomic, assign) BOOL BabyBossDefeated; 
@property (nonatomic, assign) BOOL DuckBossDefeated; 
@property (nonatomic, assign) BOOL BaseBallBossDefeated; 
@property (nonatomic, assign) BOOL NewtonBossDefeated; 
@property (nonatomic, assign) BOOL SpeedBoost; 
@property (nonatomic, assign) BOOL CatchExtender; 
@property (nonatomic, assign) BOOL SpeedBoostEnabled; 
@property (nonatomic, assign) BOOL CatchExtenderEnabled; 

// Put your custom init method interface here: 
-(id)initWithcurrency:(int)currency 
BankerBossDefeated:(BOOL)BankerBossDefeated 
BabyBossDefeated:(BOOL)BabyBossDefeated 
DuckBossDefeated:(BOOL)DuckBossDefeated 
BaseBallBossDefeated:(BOOL)BaseBallBossDefeated 
NewtonBossDefeated:(BOOL)NewtonBossDefeated 
CatchExtender:(BOOL)CatchExtender 
     SpeedBoost:(BOOL)SpeedBoost 
CatchExtenderEnabled:(BOOL)CatchExtenderEnabled 
     SpeedBoostEnabled:(BOOL)SpeedBoostEnabled; 

@end 

내 GlobalSettings.m은 다음과 같습니다 :

#import "GlobalSettings.h" 

@implementation GlobalSettings 

// Synthesize your variables here, for example: 
@synthesize currency = _currency; 
@synthesize BankerBossDefeated = _BankerBossDefeated; 
@synthesize BabyBossDefeated = _BabyBossDefeated; 
@synthesize DuckBossDefeated = _DuckBossDefeated; 
@synthesize BaseBallBossDefeated = _BaseBallBossDefeated; 
@synthesize NewtonBossDefeated = _NewtonBossDefeated; 
@synthesize SpeedBoost = _SpeedBoost; 
@synthesize CatchExtender = _CatchExtender; 
@synthesize SpeedBoostEnabled = _SpeedBoostEnabled; 
@synthesize CatchExtenderEnabled = _CatchExtenderEnabled; 

// put your custom init method here which takes a variable 
// for each class instance variable 
-(id)initWithcurrency:(int)currency 
BankerBossDefeated:(BOOL)BankerBossDefeated 
BabyBossDefeated:(BOOL)BabyBossDefeated 
DuckBossDefeated:(BOOL)DuckBossDefeated 
BaseBallBossDefeated:(BOOL)BaseBallBossDefeated 
NewtonBossDefeated:(BOOL)NewtonBossDefeated 
    CatchExtender:(BOOL)CatchExtender 
     SpeedBoost:(BOOL)SpeedBoost 
    CatchExtenderEnabled:(BOOL)CatchExtenderEnabled 
     SpeedBoostEnabled:(BOOL)SpeedBoostEnabled;{ 

if ((self = [super init])) { 

    // Set class instance variables based on values 
    // given to this method 
    self.currency = currency; 
    self.BankerBossDefeated = BankerBossDefeated; 
    self.BabyBossDefeated = BabyBossDefeated; 
    self.DuckBossDefeated = DuckBossDefeated; 
    self.BaseBallBossDefeated = BaseBallBossDefeated; 
    self.NewtonBossDefeated = NewtonBossDefeated; 
    self.CatchExtender = CatchExtender; 
    self.SpeedBoost = SpeedBoost; 
    self.CatchExtenderEnabled = CatchExtenderEnabled; 
    self.SpeedBoostEnabled = SpeedBoostEnabled; 
} 
return self; 
} 

- (void) dealloc { 
[super dealloc]; 
} 

@end 

내가 다음 SettingsParser.h으로 XML을 구문 분석 :

나는 경우 CatchExtender을 마련하고 (그들은 게임의 상점에서 구입)를 활성화 될 SpeedBoost 두 개의 스위치가 있습니다. 이러한 스위치에서 스위치에 따라 SpeedBoostEnabled 및 CatchExtenderEnabled를 설정하려고합니다. MY INIT IN

게임 수준에 대한 데이터를 보유하고있는 클래스에서, 나는이를 확인 일반적으로 간단한 if 문을 사용하여 불리언 소리를냅니다. 하지만 작동하지 않는 것 같습니다. 로그에서 XML 파일의 값이 변경된 것처럼 보이지 않기 때문에 설정이 저장되지 않는 것처럼 보입니다.

오랜 소식이지만 이번 호에 대해 사과드립니다. 좀 곤란 해.

나는 전에적인 Cocos2D를 사용한 적이 있지만이이 같은 전형적인 iOS 앱에 대한 NSUserDefaults을 사용하는 것이 정확히 무엇처럼 보인다 ... [[NSUserDefaults standardUserDefaults] setBool:YES ForKey:@"Key"];
