Question

I have a view-based app that just does one thing : show a array in a TableView, but it doesn’t work and I don’t know why. Here’s the code.

.h

@interface ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>{
    NSArray *array;
    IBOutlet UITableView *table;
}

.m

-(void)viewDidLoad{
[super viewDidLoad];
    array = [array initWithObjects:@"iPad", @"iTV", nil];

}

- (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];
    }

    cell.textLabel.text = [array objectAtIndex:indexPath.row];

    return cell;
}

Any ideas why the TableView doesn’t show the text? Thank you people!

Answer 1

array = [array initWithObjects:@"iPad", @"iTV", nil];

Should be

array = [NSArray initWithObjects:@"iPad", @"iTV", nil];

also make sure you call arrayInit as barley mentioned

edit:
Vince is right in pointing out it should either be

[[NSArray alloc] initWithObjects:@"iPad", @"iTV", nil];

or

[NSArray arrayWithObjects:@"iPad",@"iTV",nil];

depending on if you want to retain or have it auto released
