Question

So, I have an UITableView which holds entries for an app I am making. The entriesViewController is its own class, with a .xib file. I have a button that adds a new item.

It does this with the following code:

-(IBAction)newItem:(id)sender {
    LEItem *newItem = [[LEItemStore sharedStore] createItem];
    NSLog(@"New Item = %@", newItem);
    [TableView reloadData];
}

Now this works, and adds the item, however it puts it at the bottom of the list. Since this app logs things for days, I do not want the items in this order. The newest items should be placed at the top of the list. How do I do this? I didn’t see any easy way to add items to the table view at the top, but I might be missing something pretty basic.

This doesn’t seem like it should be hard, I am probably just overlooking something.

Ideas are welcome.

Here is LEItem Store:

@implementation LEItemStore
+ (LEItemStore *)sharedStore
{
    static LEItemStore *sharedStore = nil;
    if (!sharedStore)
        sharedStore = [[super allocWithZone:nil] init];

    return sharedStore;
}

+ (id)allocWithZone:(NSZone *)zone
{
    return [self sharedStore];
}

-(id)init
{
    self = [super init];
    if (self) {
        NSString *path = [self itemArchivePath];
        allItems = [NSKeyedUnarchiver  unarchiveObjectWithFile:path];

        if (!allItems)
        {
            allItems = [[NSMutableArray alloc] init];
        }
    }

    return self;
}

- (NSArray * )allItems
{
    return allItems;
}
-(LEItem *)createItem
{
    LEItem *p = [LEItem addNewItem];

    [allItems addObject:p];

    return p;
}

- (void)removeItem:(LEItem *)p
{
    [allItems removeObjectIdenticalTo:p];
}

-(void)moveItemAtIndex:(int)from toIndex:(int)to
{
    if (from == to) {
        return;
    }
    LEItem *p = [allItems objectAtIndex:from];

    [allItems removeObjectAtIndex:from];

    [allItems insertObject:p atIndex:to];
}

- (NSString *)itemArchivePath {
    NSArray *documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentDirectory = [documentDirectories objectAtIndex:0];

    return [documentDirectory stringByAppendingPathComponent:@"item.archive"];
}

-(BOOL)saveChanges {
    NSString *path = [self itemArchivePath];

    return [NSKeyedArchiver archiveRootObject:allItems toFile:path];
}
@end

It looks like the simplest solution would be to modify -[LEItemStore createItem] to this:

-(LEItem *)createItem {
    LEItem *p = [LEItem addNewItem];
    [allItems insertObject:p atIndex:0];    
    return p;
}
