基本上我有一个 NSdictionaries 数组，我想将它们存储在 NSUserDefaults 中。pageDict 是本地 NSDictionary LyteData 是用于存储内容的 Singleton 类 层次结构来自 lyteData.textbookDictArray ---> lyteData.pagesDictArray ---> pageDict (NSDictionary)

    [pageDict setObject:textbookImage forKey:@"image"];
    [pageDict setObject:textbookName forKey:@"name"];
    [pageDict setObject:page forKey:@"page"];
    [pageDict setObject:nameOfClass forKey:@"class"];

    LyteData *lyteData = [LyteData sharedManager];
    [lyteData.pagesDictArray addObject:pageDict];


    [lyteData.textbookDictArray addObject:lyteData.pagesDictArray];
       NSLog(@"array: %@", lyteData.pagesDictArray);
       NSLog(@"textbook array: %@", lyteData.textbookDictArray);

   //THIS CODE IS FOR SAVING THE ARRAY OF TEXTBOOKS AS USERDEFAULT
    [[NSUserDefaults standardUserDefaults]
     setObject:lyteData.textbookDictArray forKey:@"textbookArray"];

我收到此错误：

   Attempt to set a non-property-list object (
        {
        class = hb;
        image = "<UIImage: 0x165c43d0>";
        name = fv;
        page = 25;
    }
) as an NSUserDefaults value for key textbookArray

如何将该数组存储在 NSUserDefaults 中？
