UITableViewCell style and dequeueReusableCellWithIdentifier - ios

Question

So I register my cell:
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:#"Cell"];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// setting up the cell
}
The issue is I can't set the cell.detailTextLabel.text property. The cell is never nil.

Answer 1

If called first, table view registerClass will cause dequeueReusableCellWithIdentifier to return non-nil cell if the cell reuse identifier matches.
I believe registerClass is generally used for cells that will be a custom cell derived from UITableViewCell. Your custom cell can overrite initWithStyle and set the style there.
It's not always necessary to create a custom cell.
If you want to set the cell style then don't call registerClass.

Answer 2

you need do followed 3 changes to achieve you goal:
remove registerClass statement.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
=> UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
use initWithStyle:UITableViewCellStyleSubtitle
usually there are two ways to create cell with subtile, firstly with custom UITableViewCell, set style in the init. secondly with followed code, which is what you wanted:
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}

Answer 3

The easiest way is to use the storyboard, and set the cell style in IB. In that case, you shouldn't register anything, nor should you have an if (cell == nil) clause. It doesn't seem to matter whether you use dequeueReusableCellWithIdentifier: or dequeueReusableCellWithIdentifier:forIndexPath. They both are guaranteed to return a cell when that cell is created in the storyboard.

Answer 4

Create a custom cell. Change its style in interface builder. Use table view register the cell from nib your view controller.
And the code:
- (void)viewDidLoad {
[super viewDidLoad];
[self.tableView registerNib:[UINib nibWithNibName:#"YourCustomCell" bundle:nil] forCellReuseIdentifier:kReuseIdentifier];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
YourCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:kReuseIdentifier];
// Do things with the cell.
// The cell has no chance to be nil because you've already registered it in viewDidLoad method.
// So there's not need to write any code like if(cell==nil).
// Just use it.
return cell;
}

Answer 5

Try using the UITableViewCellStyleSubtitle style for the cell. Change the line in the if statement to this:
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];

Answer 6

You need to change the cell style:
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
to this
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
This will work for you.

Answer 7

This is an old question. I just want to provide a alternative solution.
Why not try below, after you register the cell:
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
then do:
[cell initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier ];
It works for me.
