I have a mental block, please help me

This is an Obj-C question:
I have a dictionary and I want to make an ARRAY with all keys and their objects.

It's probably something very simple like arrayFromDictionary: but my brain just melt down

Basically, I am trying to do something like a loop that does the following:

[myArray setObject:<first item in myDictionary>];
[tableView reloadData];
[myArray setObject:<next item>];

etc.

It should be possible using enumerator or something but I can't find a good example.

Anyone?

An array with all the keys and objects? Uhmm... array's hold one object each index, so you'll need to make some custom subclass that has instance variables of an object and a key.

Code:

#import <Cocoa/Cocoa.h>

@interface ObjectKeyHolder : NSObject 
{
     id object;
     id key;
}

- (id)initWithObject:(id)obj key:(id)k;
- (id)object;
- (id)key;

@end

Then you could do this:

Code:

NSDictionary *myDict;
NSArray *allKeys = [myDict allKeys];
NSEnumerator *keyEnum = [allKeys objectEnumerator];
NSMutableArray *destin = [NSMutableArray arrayWithCapacity:[allKeys count]];
id key;

while(key = [keyEnum next])
    [destin addObject:[[[ObjectKeyHolder alloc] initWithObject:[myDict objectForKey:key] key:key] autorelease]];

That should do the trick... if that's what you wanted.

Let me show you first what I did and then I will go and try if what you suggested makes sense or not. This is what I had:

oldData = [[NSDictionary alloc] initWithDictionary:[oldPrefs objectForKey:@"TableView"]];

NSEnumerator *enumerator = [oldData keyEnumerator];
id key;

while ((key = [enumerator nextObject])) {
[records addObject:&key];
}

[tableView reloadData];


But it told me that there is an error BEFORE ID KEY?????????????????

I still don't know why or what or grrrr

OK let me go and try yours.

[VEGAN]

Sorry, but that didn't work either [not even when I cleaned your mistakes [NSEnumerator does not recognize "next"]

HEEEEEEEEEEEEEEEEEEELP!!!!!!!!!!!!

Ohpps, I meant nextObject

Actually, do all you want is an array of keys?

Then just use NSDictionary's allKeys method, it's very handy

Keys WITH all the objects.
It gave me some errors when I used allKeys... let me try again.

If you need to know: IT WAS THE allValues!!!!! That did the trick... it was so simple in the end that I wanted to cry having messed most of the afternoon doing silly things
