Add Item into a a tableView ?! - xcode

Question

Hi I'm trying to create a dynamic tableView by the following method. But I'm getting an error during execution of the simulator. it works with a pre declared NSArray, but the following method doesn't work. Could you please help me on this topic ?
NSMutableArray *mesProduits;
mesProduits = [[NSMutableArray alloc] init];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellule];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:cellule];
}
for(int index = 0; index < [myObjectsFormulas count]; index = index+13)
{
monTest = [myObjectsFormulas objectAtIndex:monIndex];
monIndex = monIndex+13;
[mesProduits addObject:monTest];
}
NSString *celltext1 = [mesProduits objectAtIndex:indexPath.row];
cell.textLabel.text = celltext1;

Answer 1

I believe this is your cellForRowAtIndexPath method then do like following:
// Declare mesProduits as a property
- (void) viewDidLoad {
// Initialize and assigned values to monIndex and myObjectsFormulas
self.mesProduits = [[NSMutableArray alloc] init];
for(int index = 0; index < [myObjectsFormulas count]; index = index+13)
{
monTest = [myObjectsFormulas objectAtIndex:monIndex];
monIndex = monIndex+13;
[self.mesProduits addObject:monTest];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellule];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:cellule];
}
NSString *celltext1 = [self.mesProduits objectAtIndex:indexPath.row];
cell.textLabel.text = celltext1;
}
