cellForRowAtIndexPath returning custom cell? - iphone

Question

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// ...
PlanetTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"PlanetCell_ID"];
return cell;
}
If your creating a custom UITableViewCell (in this case PlanetTableViewCell) is it acceptable to return that object via a method returning (UITableViewCell *), or is there something else I should be doing?

You possibly meant:
to return that object via a method returning (UITableViewCell*),
If so, then it is perfectly legal and reasonable.
Indeed, your PlanetTableViewCell being derived from UITableViewCell, all instances of PlanetTableViewCell are also of the type UITableViewCell (is-a relationship in OOP).

Answer 2

Yes, this is the correct way to return the cell.
But you should also be checking to see if your "dequeue" is returning a valid cell object. If not, you'll need to create one.
This method is also where you should be configuring your cell with title, accessories, etc.
Sample code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// ...
PlanetTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"PlanetCell_ID"];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
cell.titleLabel.text = #"Cell Title";
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}

Answer 3

Using custom cell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier;
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
simpleTableIdentifier = #"dashboard_logintimeCell_ipad";
}
else
{
simpleTableIdentifier = #"dashboard_logintimeCell";
}
dashboard_logintimeCell *cell = (dashboard_logintimeCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib =[[NSBundle mainBundle]loadNibNamed:simpleTableIdentifier owner:self options:nil];
cell = [nib objectAtIndex:0];
}
/*here you cell object get
like
cell.lable.text=#"yourlabeltext";
*/
cell.backgroundColor=[UIColor clearColor];
return cell;
}
