Group Array of Dictionaries containing Dictionaries with Duplicate Values

Question

I currently am working on a grouped tableView. I have it working but want to change my incoming arrays into dictionaries to provide more useful information in tableview. The DictionaryHolder has all different keys which is the name, it contains a dictionary with "mainTheme" key some of these mainKeys match and I would like to compile those matching dictionary into array and then back into a new dictionary with new key "subThemes" which is the array of dictionary set contains matches of "mainTheme"... Ive hit a wall and don't know how to approach this which methods would be the fastest because at times there could be a lot of dictionaries being created and sorted. Any help would be greatly appreciated!

-(NSMutableArray*)themesDictFromThemesPlists:(NSMutableArray*)allThemesonDevice{

NSMutableDictionary *compiledThemesDictionaryHolder = [[NSMutableDictionary alloc]init];
NSMutableArray *returnedDict = [[NSMutableArray alloc]init];
NSMutableDictionary *mainThemeCompiled = [[NSMutableDictionary alloc]init];
NSMutableDictionary *themePlistDict = nil;
NSString *packageName= nil;
NSString*fullPlistStr = nil;
NSString *themeStringToDeconstruct = nil;


//create dictionary for each theme
NSMutableArray *allPckgNames = [[NSMutableArray alloc]init];
for (NSString *actualName in allThemesonDevice) {

    themeStringToDeconstruct = actualName;
    if ([themeStringToDeconstruct hasSuffix:@".theme"]) {
        themeStringToDeconstruct = [themeStringToDeconstruct stringByReplacingOccurrencesOfString:@".theme" withString:@""];
    }
    themeStringToDeconstruct = [themeStringToDeconstruct stringByReplacingOccurrencesOfString:@"_" withString:@" "];
    NSArray *theWords = [themeStringToDeconstruct componentsSeparatedByString:@" "];
    NSString *nameWithoutTags = [theWords objectAtIndex:0];
    //NSLog (@"ICONOMATIC OBJECT AT INDEX 0 %@",newName);


    fullPlistStr = [NSString stringWithFormat:@"/Library/Themes/%@/Info.plist",actualName];
    themePlistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:fullPlistStr];
    packageName = [themePlistDict objectForKey:@"PackageName"];
    //NSLog (@"ThemePlistDict: %@",themePlistDict);
    //NSLog (@"ICONOMATIC Actual Name : %@ PackageName: %@",actualName,packageName);


    if (packageName) {

        NSMutableDictionary *compiledTheme = [[NSMutableDictionary alloc]init];
        [compiledTheme setValue:actualName forKey:@"fullThemeName"];
        [compiledTheme setValue:nameWithoutTags forKey:@"themeName"];
        [compiledTheme setValue:packageName forKey:@"mainTheme"];

        //can add more icons

Ok so here was my overall solution. The main issue was determining the available matching objects in array of dictionary and was solved by using indexesOfObjectsPassingTest and enumerateIndexesUsingBlock

 -(NSMutableArray*)themesDictFromThemesPlists:(NSMutableArray*)allThemesonDevice{

NSMutableArray *compiledThemesDictionaryHolder = [[NSMutableArray alloc]init];
NSMutableArray *returnedArrayOfDicts = [[NSMutableArray alloc]init];
NSMutableDictionary *themePlistDict = nil;
NSString *packageName= nil;
NSString*fullPlistStr = nil;


//create dictionary for each theme
NSMutableArray *allPckgNames = [[NSMutableArray alloc]init];
for (NSString *actualName in allThemesonDevice) {

    fullPlistStr = [NSString stringWithFormat:@"/Library/Themes/%@/Info.plist",actualName];
    themePlistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:fullPlistStr];
    packageName = [themePlistDict objectForKey:@"PackageName"];
    //NSLog (@"ThemePlistDict: %@",themePlistDict);
    //NSLog (@"ICONOMATIC Actual Name : %@ PackageName: %@",actualName,packageName);


    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]]) {
            [compiledTheme setValue:[NSString stringWithFormat:@"/Library/Themes/%@/Icon.png",actualName]  forKey:@"icon1"];
            [compiledTheme setValue:@"prominate" forKey:@"prominate"];
            //can add more icons to dict
        }
        if ([[NSFileManager defaultManager] fileExistsAtPath:[NSString stringWithFormat:@"/Library/Themes/%@/icon.png",actualName]]) {
            [compiledTheme setValue:[NSString stringWithFormat:@"/Library/Themes/%@/icon.png",actualName]  forKey:@"icon1"];
            //can add more icons to dict

        }
        //NSLog (@"Iconomatic ADD compiledTheme %@ ",compiledTheme);

        //these arrays below should have same indexes to objects but (allPackgNames) can easliy be grouped
        [compiledThemesDictionaryHolder addObject:compiledTheme];

        [allPckgNames addObject:packageName];

}
    }


 //NSLog (@"Iconomatic compiledThemesDictionaryHolder %@ ",compiledThemesDictionaryHolder);

    //check for pckg name. Array may contain several matches so remove those at end of loop
    if ([allPckgNames containsObject:mainThemeName]) {

        //gather index set of any matches
        NSIndexSet *indxs = [compiledThemesDictionaryHolder indexesOfObjectsPassingTest:^BOOL(NSDictionary *dict, NSUInteger idx, BOOL *stop) {

        }];
        //NSLog(@"Iconomatic indexSet %@",indxs);

        //enumerate those index sets to grab dictionaries and store in (subThemes)
        NSMutableArray *subThemeArray = [[NSMutableArray alloc]init];

OutPut of Main Theme is now

 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";
}
 )

and Final is:

  Iconomatic returnedArrayOfDicts (
    {
    fullThemeName = "Bohemic NOIR alt.theme";
    icon1 = "<UIImage:0x281f48b40 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;
        },
