NSMutableArray 不会添加 NSDictionary

Question

我将cocos2d从0.99.4更新到0.99.5。虽然它是在旧版本上，但我的高分列表正常工作，并且我能够毫无问题地将 NSDictionary 添加到 NSMutableArray 中。

现在我已经更新了，它不会将 NSDictionary 变量 ScoreDetails 添加到我的 NSMutableArray ScoreList 中。这是我的代码：

StatsManager.h

@interface StatsManager : NSObject {
NSMutableArray *scoreList;
NSUserDefaults *saveHighScore;
NSMutableArray *printableScoreList;

//NSMutableArray *scoreListTestOne;
float highScoreHelloWorld;
}

StatsManager.m

-(void)setHighScore:(float)highScore nameStrings:(NSString*)nameString {

NSNumber *newHighScore = [NSNumber numberWithFloat:highScore];
NSLog(@"%@ highScore", newHighScore);

NSDictionary *scoreDetails = [NSDictionary dictionaryWithObjectsAndKeys:nameString, @"name", newHighScore, @"score", nil];

NSLog(@"%@", scoreDetails);
//NSMutableArray *testTwo = [[NSMutableArray alloc] init];
[scoreList addObject:scoreDetails];
NSLog(@"scoreList %@", scoreList);
//[scoreListTestOne addObject:scoreDetails];
//NSLog(@"scoreListTestOne %@", scoreListTestOne);
//sort
NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"score" ascending:NO];
[scoreList sortUsingDescriptors:[NSArray arrayWithObject:sort]];

printableScoreList = scoreList;
NSLog(@"printableScoreList %@", printableScoreList);
//NSLog(@"scoreListTestOne %@", scoreListTestOne);
}

有问题的行是

    [scoreList addObject:scoreDetails];

我在 setHighScore 函数中创建了一个本地 NSMutableArray 变量，并尝试将 ScoreDetails 添加到其中，它成功了。但为什么它不再像我上面编码的那样工作了？

我在这里分配 init 我的 ScoreList：

@implementation StatsManager
static StatsManager *_sharedStatsManager = nil;
-(id)init {
    scoreList = [[NSMutableArray alloc] init];
    //playerNames = [[NSMutableArray alloc] init];
    //playerScores = [[NSMutableArray alloc] init];
    printableScoreList = [[NSMutableArray alloc] init];

//listOfScoresTest = [[NSMutableDictionary alloc] initWithCapacity:5];
/*if ([scoreList count] == 0) {
    for (int i = 0; i < 5; i++) {
        [scoreList addObject:[NSNumber numberWithFloat:0.00]];
    }
}*/

return [super init];
}

我还应该提到，我创建了一个新项目 B 并将我的文件/图像从旧项目 A 转移到新项目，因为旧项目由于一些重复错误而无法再编译。但我再次“清理了所有目标”并且它起作用了，但这也与我的新项目B有同样的问题

Answer 1

您是否在 init 等中初始化 ScoreList ivar？

- (id)init
{
    /* snip */
    scoreList = [[NSMutableArray alloc] init];
    return self;
}

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

好吧，乔治，我重新考虑了你关于稍后覆盖它的建议。

这与我的 NSUserdefaults 有关。我将它们注释掉，现在它将对象添加到我的 NSMutableArray 中。我对 NSUserdefaults 很陌生，所以我不知道如何使用它 atm 哈哈

    -(void)save
{

    //make another array to save the scores.
    saveHighScore = [NSUserDefaults standardUserDefaults]; 
    //[saveHighScore setObject:scoreListNew forKey:@"DodgerAppBeta"];
    [saveHighScore synchronize];
    //[[NSUserDefaults standardUserDefaults] setObject:scoreListTestOne forKey:@"DodgerBeta"];
    //[[NSUserDefaults standardUserDefaults] synchronize];  
}

-(void)load
{

    saveHighScore = [NSUserDefaults standardUserDefaults];
    //scoreListNew  = [[saveHighScore objectForKey:@"DodgerAppBeta"] mutableCopy];

    printableScoreList  = [[saveHighScore objectForKey:@"DodgerAppBeta"] mutableCopy];
    //NSLog(@"scoreListTestOne %@", scoreListTestOne);
    //[printableScoreList addObject:[[NSUserDefaults standardUserDefaults] objectForKey:@"Dodger"]];
    NSLog(@"PSL %@", printableScoreList);
}
