Importing Array and Using in Table

[kahanejosh]

Hi

I have an issue with an imported array and UITableView. I have imported the view mondayView and am trying to access monArray from that view. Here is my code. The bold gets the following error:

Expected ':' before '.' token.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return [mondayView.monArray count];
}


- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    // Return the number of rows in the section.
    return 10;
}


// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    
    // Configure the cell...
    cell.textLabel.text = [mondayView.monArray objectAtIndex:indexPath.row];
    return cell;
}

the syntax you are using, "mondayView.monArray", assumes that your MondayView object has a property monArray. The error you say you're getting suggests that you have an instance variable monArray, but forgot to declare it as a property of your mondayView object.

Ok interesting. Well mondayView isn't an object, its a UIViewController. Does it need to be an object to perform that?

A view controller is an object

Ahh ok, I was thinking of UIViewController aposed to NSObject. Anyway, I have declared it like this:

@property (nonatomic, retain) NSMutableArray *monArray;

Is that correct?

Ok while trying to get out the easy way, I have been able to work out how to use a singleton object! Finally found somewhere which explained it so I could understand. Anyway I have it working globally now. Thanks.
