Question

现在我已经在应用程序商店中创建了我的游戏“激光防御者”，但我有一件事我想不通，如何将高分存储在游戏的列表中。我有一个标签可以计算被摧毁的敌舰数量，但是我如何将最好的这些分数存储在列表中呢？这是我更新enemiesShot标签的代码：

（void）update：（ccTime）dt {

NSMutableArray * projectilesToDelete = [[NSMutableArray alloc] init]; for（CCSprite * _jejectiles中的弹丸）{ CGRect projectileRect = CGRectMake（ projectile.position.x - （projectile.contentSize.width / 2）， projectile.position.y - （projectile.contentSize.height / 2）， projectile.contentSize.width， projectile.contentSize.height）;
```
NSMutableArray *targetsToDelete = [[NSMutableArray alloc] init];
for (CCSprite *target in _targets) {
    CGRect targetRect = CGRectMake(
                                   target.position.x - (target.contentSize.width/2),
                                   target.position.y - (target.contentSize.height/2),
                                   target.contentSize.width,
                                   target.contentSize.height);

    if (CGRectIntersectsRect(projectileRect, targetRect)) {
        [targetsToDelete addObject:target];
    }
}

for (CCSprite *target in targetsToDelete) {
    [_targets removeObject:target];
    [self removeChild:target cleanup:YES];
    _enemiesShot++;
    [_enemiesShotLabel setString:[NSString stringWithFormat:@"%d",_enemiesShot]];



}

if (targetsToDelete.count > 0) {
    [projectilesToDelete addObject:projectile];
}
[targetsToDelete release];
```
}

for（CCSprite * projectiles in projectilesToDelete）{ [_projectiles removeObject：projectile]; [self removeChild：projectile cleanup：YES]; } [projectilesToDelete release];

}

试试这个：

NSUserDefaults的

保存

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// saving an NSString
[prefs setObject:@"TextToSave" forKey:@"keyToLookupString"];

// saving an NSInteger
[prefs setInteger:42 forKey:@"integerKey"];

// saving a Double
[prefs setDouble:3.1415 forKey:@"doubleKey"];

// saving a Float
[prefs setFloat:1.2345678 forKey:@"floatKey"];

// This is suggested to synch prefs,
[prefs synchronize];

检索

NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];

// getting an NSString
NSString *myString = [prefs stringForKey:@"keyToLookupString"];


// getting an NSInteger
NSInteger myInt = [prefs integerForKey:@"integerKey"];

// getting an Float
float myFloat = [prefs floatForKey:@"floatKey"];

当应用程序正在运行时，只需将所有数据保存在某些NSArray / MutableArray中，当应用程序即将进入后台时，将“保存”部分放在“applicationDidEnterBackground”中。

当应用程序恢复时，从“UserDefaults”中取回所有数据（检索上面的代码）。将该代码放在“ApplicationDidEnterForeground”中。重新启动应用程序时，使用“ViewDidLoad”检索代码。
