Question

Im very new in xcode 3 and i really need help for this

I developed my apps using UITableView and XML to showed the content.

i had 3 .xib files which it rootViewController , SecondViewController and mainview.

So the problem is:
When i try to executed didSelectrow in rootViewController and access the NSMutableArray *array in SecondViewController and replace the *array value with new array value in rootViewController before pushed animation.

The array value on my SecondViewController was changed for the first time but when i pushed the back button and select the other row, my SecondViewController array kept read the previous array not change to a new one. I try to initialize but no luck

This is my code on rootViewController UITableview (didSelectRow):

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    if(2ndController == nil)

2ndController = [[DetailViewController alloc] initWithNibName:@"SecondViewController" bundle:[NSBundle mainBundle]];

    //Declare xml NSMutable array record
    ListRecord *record = [self.entries objectAtIndex:indexPath.row];

    //access SecondViewController NSMutable *record
    2ndController.record = [[[NSMutableArray alloc] init] autorelease];   

        //inserting the value from firstview to secondview before push
    2ndController.record = record;



    //push animation
    [self.navigationController pushViewController:2ndController animated:YES];



}

This is my second view controller :

- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }

    switch(indexPath.section)
    {
        case 0:

            [cell setText:record.name];
            break;
        case 1:

            [cell setText:record.Age];
            break;
        case 2:
        [cell setText:record.summary];
            break;
    }

    return cell;
}

Hope someone can help me..

Thanks in advance…..

Answer 1

Few things,

You do,

2ndController.record = [[[NSMutableArray alloc] init] autorelease];

and follow it up with

[cell setText:record.name];

Clearly, the record property doesn’t seem to be an instance of NSMutableArray so I think the array initialization part is incorrect as you do, and already mentioned,

2ndController.record = record;

But the problem I think is that you are retaining your UITableViewController subclass. Have you tried reloading the data?

[self.tableView reloadData];

Add it in the viewWillAppear method of your DetailViewController.
