Question

I have an app where a UITableView is populated by a NSMutableArray. The problem is that when I add strings to the Array, it isn’t at the TableView. Here’s the code:

.h

<UITableViewDelegate, UITableViewDataSource>{
IBOutlet UITableView *table;
NSMutableArray *array;
}

.m

- (void)viewDidLoad{
array=[[NSMutableArray alloc] init];
}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [array count];
}

- (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];
    }

    NSInteger row = [indexPath indexAtPosition:1];
    cell.textLabel.text = [array objectAtIndex:row];
    return cell;
}

-(void)addObjectsToTheArray{
    NSString *stringA = @"something";
    NSString *stringB = @"moreofsomething" ;
    [array addObject:stringA];
    if (![stringA isEqual: stringB]) {
        stringA = @"somethingtoo"  
        [array addObject: stringB];
        [table beginUpdates];
    }
}

Anyone has idea why it doesn’t reload the data? I don’t know why it doesn’t work, and it doesn’t give to me any error.

Answer 1

Do you invoke [table reloadData]; somewhere in your code?

Have you set dataSource and delegate for your table?
