Write NSArray to plist file

Question

I have a code to get the data of a plist file and a code to write data to a plist file. Now the things is, that it add's the readed data in one array (See images). I want it in different arrays (See green image)

HERE IS MY CODE:

- (void)WriteData {
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *path = [documentsDirectory stringByAppendingPathComponent:@"MuziekList.plist"];

if ([fileManager fileExistsAtPath:path] == NO) {
    NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"MuziekList" ofType:@"plist"];
    [fileManager copyItemAtPath:resourcePath toPath:path error:&error];
}
//_______________________________________________________________________________________________________________
NSMutableDictionary *savedStock = [[NSMutableDictionary alloc] initWithContentsOfFile: path];

//load from savedStock example int value
NSArray *NummerTexts;
NummerTexts = [savedStock objectForKey:@"Nummers"];
NSString *NummerTextsR = [[NummerTexts valueForKey:@"description"] componentsJoinedByString:@" - "];

NSArray *ArtiestTexts;
ArtiestTexts = [savedStock objectForKey:@"Artiesten"];
NSString *ArtiestTextsR = [[ArtiestTexts valueForKey:@"description"] componentsJoinedByString:@" - "];
//_______________________________________________________________________________________________________________

NSUserDefaults *CurrentVideoNummerResult = [NSUserDefaults standardUserDefaults];
NSString *CurrentVideoNummer = [CurrentVideoNummerResult stringForKey:@"CurrentVideoNummer"];

NSUserDefaults *CurrentVideoArtiestResult = [NSUserDefaults standardUserDefaults];
NSString *CurrentVideoArtiest = [CurrentVideoArtiestResult stringForKey:@"CurrentVideoArtiest"];

/*
NSUserDefaults *CurrentVideoIDResult = [NSUserDefaults standardUserDefaults];
NSString *CurrentVideoID = [CurrentVideoIDResult stringForKey:@"CurrentVideoID"];
*/

NSMutableDictionary *plist = [[NSDictionary dictionaryWithContentsOfFile:path] mutableCopy];
NSMutableArray *newArray = [[NSMutableArray alloc] init];
NSMutableArray *newArray2 = [[NSMutableArray alloc] init];

newArray = [NSMutableArray arrayWithObjects:CurrentVideoNummer, NummerTextsR, nil];
[plist setObject:newArray forKey:@"Nummers"];


newArray2 = [NSMutableArray arrayWithObjects:CurrentVideoArtiest, ArtiestTextsR, nil];
[plist setObject:newArray2 forKey:@"Artiesten"];

[plist writeToFile:path atomically:YES];
}

Answer 1

Your question and problem are confusing. Maybe this will help:

Your code reads your current array (NummerTexts), flattens that array to a single string (NummerTextsR), gets a second string (CurrentVideoNummer), then builds a two-element array (newArray).

Your question appears to be why do you get a two-element array...?

If you don't want to flatten your original array don't do so, just make a mutable copy of it, something like:

NSMutableArray *existingTexts = [[NummerTexts valueForKey:@"description"] mutableCopy];

add your new element:

[existingTexts addObject:currentVideoNummer];

and write it back like you already are.

HTH

BTW Do not start local variable names with an uppercase letter, this goes against convention and is why the syntax highlighting in your question is all wrong.
