Question

i started a tabbed application project, and on my first view i want to get a populated list so i declared a NSArray like follow:

@interface agrospineFirstViewController : UIViewController <UITableViewDelegate     ,UITableViewDataSource>
{
NSArray  *JournalList;
}
@property (nonatomic,retain) NSArray *JournalList;
@end

and i added the following on the .m :

[super viewDidLoad];

//initialisation de la liste
JournalList = [NSArray arrayWithObjects:@"journal1",@"journal2",nil];


//initialisation du table View 
UITableView* tableView=[[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]style:UITableViewStylePlain];


//population de la vue


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

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = @"MyIdentifier";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];

if (cell == nil)

    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier];

// Configuration de la cellule

NSString *cellValue = [JournalList objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
return cell;

}

i also droped the tablelist into the view… but still showing an error on numberOfRowsInSection asking to replace “:” by “;”
any help advice to improve ?

Thank you for your time

I think you have not closed viewDidLoad method like this:

- (void)viewDidLoad {
  [super viewDidLoad];

  //initialisation de la liste
  JournalList = [NSArray arrayWithObjects:@"journal1",@"journal2",nil];


  //initialisation du table View 
  UITableView* tableView=[[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]style:UITableViewStylePlain];


  //population de la vue
}

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

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
  static NSString *MyIdentifier = @"MyIdentifier";

  UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];

  if (cell == nil)

    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier];

  // Configuration de la cellule

  NSString *cellValue = [JournalList objectAtIndex:indexPath.row];
  cell.textLabel.text = cellValue;
  return cell;

}
