I have a table with cells where the subtitle only appears after something has been searched. This is the code for cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
if(tableView == self.tableView)
{
// Configure the cell...
cell.textLabel.text = self.objects[indexPath.row];
cell.detailTextLabel.text = #"test2";
}
else{
// Configure the cell...
cell.textLabel.text = self.results[indexPath.row];
cell.detailTextLabel.text = #"test1";
}
return cell;
}
EDIT: ArtOfWarfare's answer was correct. it was a problem in the storyboard. See image below:
Your code suggests that you have two separate tables... I would suggest that your problem lies within the differences in how the tables have been configured, possibly in your Storyboard.
Do you, perchance, have one of them set with a prototype with an identifier of "Cell" but a style that isn't UITableViewCellStyleSubtitle? That would make it so that your cell creation method isn't called in one, but only in the other.

I'm unable to display any accessories in my UITableView cells:
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = #"Foo";
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
Changing the cell styles shows no difference. What's going on here?
Deleting and then creating a new file fixed the problem.
This was a result of having started with an xib file, and then deleted it in favor of doing the whole thing programmatically. Somehow, after deleting the xib, some of the delegation settings stuck.
I have a UITableView with sections inside of them. All works great, but I can't seem to figure out how to customize the very fist index path. For example, I know this is very easily achievable through a normal tableview like so:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell*cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
if(!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"cell"];
if (indexPath.row == 0)
{
cell.detailTextLabel.text = #"My Custom text";
NSLog(#"%#",pm1.customText1);
}
}
}
I have tried the above implementation and it does not seem to work for me. Is there a different approach for section headers to achieve the same result with a normal tableview? Do I need to inject a "fake" section in my dictionary?
-(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];
}
if (indexPath.row == 0) {
cell.detailTextLabel.text = #"My Custom text";
NSLog(#"%#",pm1.customText1);
}
return cell;
}
Try this
The way you have it now the first cell is customize only when cell is nil.
You should move it out of the if statement.
- (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];
}
//check for first cell
if (indexPath.row == 0) {
cell.detailTextLabel.text = #"My first Cell";
NSLog(#"%#",pm1.customText1);
}else{
cell.detailTextLabel.text = #"Other cells";
NSLog(#"other cells");
}
return cell;
}
I am writing the code to populate a UITableView from using a CoreData database wrapped in magical record. For some reason though the code docent seem to be working and my cell is considered nil. Why is this happening?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// Configure the cell...
PassWhizEntity *pazz = [allPasses objectAtIndex:indexPath.row];
cell.textLabel.text = pazz.destinationTeacherAttribute;
//cell.detailTextLabel.text = [self.dateFormatter stringFromDate:pazz.dateAttribute];
if (cell == nil)
{
NSLog(#"cell was nil");
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
return cell;
}
it just prints cell was nil and loads a blank UITable. Any ideas?
Your code should be like
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
NSLog(#"cell was nil");
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
PassWhizEntity *pazz = [allPasses objectAtIndex:indexPath.row];
cell.textLabel.text = pazz.destinationTeacherAttribute;
//cell.detailTextLabel.text = [self.dateFormatter stringFromDate:pazz.dateAttribute];
return cell;
}
You are trying to set textLabel of unallocated cell which have no effect on cell. Cell is returned nil because tableview don't have any cell that can be reused, so it is your responsibility to check for nil and make new Cell if needed.
I'm trying to add a subtitle to my tableview cells, but they are not displayed.
Where is the mistake?
Is the row
[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle]
up-to-date, also with iOS 7?
Best regards

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = #"TestA";
cell.detailTextLabel.text = #"TestB";
return cell;
}
This code:
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
will never execute because dequeueReusableCellWithIdentifier: forIndexPath: is guaranteed to allocate a new cell.
Unfortunately, registerClass:forCellReuseIdentifier: doesn't let you specify a UITableViewCellStyle.
Change dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath to simply dequeueReusableCellWithIdentifier:CellIdentifier. This method does not guarantee a cell will be returned.* When it's not, your code will then create a new cell with the style you want.
* - (It will if you're using a storyboard, as rdelmar points out, but that's not the case here.)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"cell"];
}
cell.textLabel.text = #"Title1";
cell.detailTextLabel.text = #"Subtitle 1";
return cell;
}
I had a similar problem and no solution on the internet worked for me. Turns out I was being an idiot. I'll post my solution just incase someone else experience a similar scenario.
I am assuming that you are using storyboard, have created a prototype and set the style to subtitle
In your storyboards document outline, make sure you select the protoptype cell and select the subtitle. See image:
Now ensure that the label font colour is of a nature that us visible on your background!
Simply subclass UITableViewCell and override
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier;
with the first line being
[super initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:reuseIdentifier];
And register your cell class with the table view
[tableView registerClass:[YourCellSubclass class] forCellReuseIdentifier:#"YourCellID"];
I'm having an issue in trying to display info in a cell, one on the left and one on the right. I'm aware using initWithStyle with UITableViewCellStyleSubtitle. I use this but it doesn't seem to work.
Here is some sample code:
- (UITableViewCell *)tableView:(UITableView *)ltableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Account Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:Cellidentifier];
}
Accounts *account = [self.fetchedResultsController objectAtIndexPath];
cell.textLabel.text = account.name;
cell.detailTextLabel.text = #"Price";
return cell;
}
I can display cell.textLabel.text just fine, however I cannot get the simple "Price" to be displayed. I've tried different things, such as setting the font size of cell.detailTextLabel.
I've also tried UITableViewCellStyleValue1 as some had suggested in older posts.
Threw NSLog after setting to "Price", shows cell.detailTextLabel as null.
Not sure what I'm doing wrong.
Edit: I found this: cell.detailTextLabel.text is NULL
If I remove if (cell == nil) it works...
That check should be in place, so how do you make it work when using the different styles?
When using storyboards and prototype cells, a cell is always returned from the dequeue method (assuming a prototype with that identifier exists). This means you never get into the (cell == nil) block.
In your case the prototype cell is not defined in the storyboard with the subtitle style, so a subtitled cell is never used, and the detail text label does not exist. Change the prototype in the storyboard to have the subtitle style.
Remove all your code just once you try these lines only and check this will work or not.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:CellIdentifier]
autorelease];
}
cell.textLabel.text=[Array objectAtIndex:indexPath.row];
cell.detailTextLabel.text=#"Price";
return cell;
}
I see the problem: in your method name, the UITableView variable is named ltableView, not tableView. Change it to tableView.
cell.detailTextLable.text should be cell.detailTextLabel.text. It looks like a simple mis-spelling of label.
All the answers mentioned here are really a workaround i.e. using storyboard.
Here is a way to do it only in code.
Basically instead of registering the identifier for the cell in viewDidLoad do it only once in cellForRowAtIndexPath: method. Also reset cell registered in viewDidLoad __sCellRegistered = 0;
static int _sCellRegistered = 0;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = nil;
if (__sCellRegistered == 0) {
__sCellRegistered = 1;
NSLog(#"register cell");
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:#"CellIdentifier"];
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:#"CellIdentifier"];
};
if (!cell) {
NSLog(#"dequeue");
cell = [tableView dequeueReusableCellWithIdentifier:#"CellIdentifier" forIndexPath:indexPath];
}
