【中文标题】包含具有重复值的字典的字典组数组【英文标题】：Group Array of Dictionaries containing Dictionaries with Duplicate Values 【发布时间】：2020-03-23 18:39:34 【问题描述】：我目前正在开发一个分组的 tableView。我让它工作但想将我的传入数组更改为字典以在 tableview 中提供更多有用的信息。 DictionaryHolder 具有所有不同的键，即名称，它包含一个带有“mainTheme”键的字典，其中一些主键匹配，我想将这些匹配的字典编译成数组，然后用新键“subThemes”编译回一个新字典字典集的数组是否包含“mainTheme”的匹配项...我碰壁了，不知道如何解决这个问题，哪种方法最快，因为有时可能会创建和排序很多字典。任何帮助将不胜感激！

【问题讨论】：
命名NSMutableArray *returnedDict = [[NSMutableArray alloc]init];，这是个坏主意。 returnedDicts（带有“s”）可能会稍微好一些，但仍然如此。你能缩进你的代码吗？也许创建子方法，因为我认为//create dictionary for each theme 部分增加了复杂性，并不是真正需要的。另外，我强烈建议使用自定义对象而不是NSDictionary，任何键中的错误都会被破坏。你能显示简单的输入和预期的输出吗？
这是有用的输入。我承认我的命名约定有时可能有点古怪，尽管我知道它的含义并且每个生命周期只使用一次 IK 更改为更合适的名称。我将研究使用自定义对象，我通常会在对象未知时使用，但在我的情况下，我确切地知道它们将永远是什么，除非它们为空。我已经更新了我的答案，现在可以正常工作了。谢谢
【参考方案1】：
好的，这就是我的整体解决方案。主要问题是确定字典数组中可用的匹配对象，并通过使用 indexOfObjectsPassingTest 和 enumerateIndexesUsingBlock 解决
-(NSMutableArray*)themesDictFromThemesPlists:(NSMutableArray*)allThemesonDevice
NSMutableArray *compiledThemesDictionaryHolder = [[NSMutableArray alloc]init];
NSMutableArray *returnedArrayOfDicts = [[NSMutableArray alloc]init];

if (packageName)
NSMutableDictionary *compiledTheme = [[NSMutableDictionary alloc]init];
[compiledTheme setValue:actualName forKey:@"fullThemeName"];
[compiledTheme setValue:packageName forKey:@"mainTheme"];
if ([[NSFileManager defaultManager] fileExistsAtPath:[NSString stringWithFormat:@"/Library/Themes/%@/Icon.png",actualName]])

[returnedArrayOfDicts addObject:mainThemeDict];
//end of (mainTheme in allPackNames)
NSLog(@"Iconomatic returnedArrayOfDicts %@",returnedArrayOfDicts);
return returnedArrayOfDicts;
现在主要主题的输出是
ICONOMATIC BUILD~ MainTheme: Lotus Dark Dict:
fullThemeName = "Lotus Dark Apps";
mainTheme = "Lotus Dark";
subThemes: (
fullThemeName = "Lotus Dark Apps";
mainTheme = "Lotus Dark";
,
fullThemeName = "Lotus Dark Apps (Alternate)";
mainTheme = "Lotus Dark";
,
fullThemeName = "Lotus Dark Calendar";
mainTheme = "Lotus Dark";
,
fullThemeName = "Lotus Dark Icon Effect";
mainTheme = "Lotus Dark";
,
fullThemeName = "Lotus Dark Mask";
mainTheme = "Lotus Dark";
,
fullThemeName = "Lotus Dark Settings";
mainTheme = "Lotus Dark";
,
fullThemeName = "Lotus Dark Widgets";
mainTheme = "Lotus Dark";
)
最后是：
Iconomatic returnedArrayOfDicts (
fullThemeName = "Bohemic NOIR alt.theme";
icon1 = "<UIImage:0x281f48b40 anonymous 300, 300>";
icon2 = "<UIImage:0x281f5f9f0 anonymous 300, 300>";
icon3 = "<UIImage:0x281f5fba0 anonymous 300, 300>";
icon4 = "<UIImage:0x281f5fcc0 anonymous 300, 300>";
isActive = 1;
themeName = BohemicNOIR;
themeSubCount = 7;
themesSubThemes = (
fullThemeName = "Bohemic NOIR alt.theme";
icon1 = "/Library/Themes/Bohemic NOIR alt.theme/icon.png";
mainTheme = BohemicNOIR;
,
fullThemeName = "Bohemic NOIR badges.theme";
icon1 = "/Library/Themes/Bohemic NOIR badges.theme/icon.png";
mainTheme = BohemicNOIR;
