This may be a stupid question, but:

I have a table in an application I'm making which would
require large amounts of information to be stored in it (100's, in fact).

So the question is - how would I go about using a Property List
(.plist) dictionary to store the various values?

I already have a data source setup (and the table works fine),
but I want to use a plist.


Any help would be appreciated.

+[NSArray arrayWithContentsOfFile:]

and

-[NSArray writeToFile:atomically:]

These read/write an array to/from a .plist file. All you need to do is put your data in an NSArray (providing you haven't done so already).

Make sure that the only items in the array (and the items they contain in) are either NSStrings, NSNumbers, NSURLs, NSDictionarys, other NSArrays or instances of NSData (there may be more that I've forgotten). You can't put other classes (like NSView, or your own custom classes) in an an NSArray if you want to store it in a .plist file.

It's all here:

OK, the table is basically two columns, one with numbers,
the other with descriptions (of emoticons).

So, my code is:

- (id)init
{
[super init];

Smile *name = [[Smile alloc] init];
NSString *path = [[NSBundle mainBundle] pathForResource:@"Smilies" ofType:@"plist"];
NSMutableArray *smilies = [NSMutableArray arrayWithContentsOfFile:path]; //reading the plist



[name setURL:@"412"]; //the first column
[name setName:@"Big Grin"]; //the second

items = [[NSMutableArray alloc] init];
[items addObject:name];
[name release];
return self;
}

So how would I insert a value from the plist
into, say the first column?

Sorry, I'm new to doing this.

You don't. NSTableView and friends ask *you* what values to display. You can tell them that new data is available by with -[NSTableView reloadData]. You should really read Apple's docs on NSTableView, they explain it very clearly. In Cocoa, you will *never* say something like "insert this data before row 8", but rather the NSTableView will determine what rows it is currently displaying, and ask its data source object for the data to display in those rows.
