嘿伙计们 - 我正在写一个非常简单的iPhone应用程序.数据来自plist文件(基本上是NSDictionary),我正在尝试加载到单例类中,并使用我的各种视图控制器来访问数据.

这是我的单例的实现(在此线程之后重新建模)

@implementation SearchData

@synthesize searchDict;
@synthesize searchArray;

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

        searchArray = [searchDict allKeys];
    }

    return self;
}

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

static SearchData *sharedSingleton = NULL;

+ (SearchData *)sharedSearchData {
    @synchronized(self) {
        if (sharedSingleton == NULL)
            sharedSingleton = [[self alloc] init];
    }   
    return(sharedSingleton);
}

@end

所以每当我尝试访问我的应用程序中的其他地方的searchDict或searchArray属性时(如TableView委托),如下所示:
