I don't understand why the label i had in my storyboard don't show up when a run the app with IOS8 and XCODE 6.1.1
I have bound my label to a custom UiTableviewCell and i can set the text but my label don't appear in the subview of the content view of the cell return by tableView dequeueReusableCellWithIdentifier:CellIdentifier];
If a using [self.tableView registerClass:[NewGameCell class] forCellReuseIdentifier:#"ListNewGameCell"];
I can't use the storyboard.
I read all the others question and i can't find the answer.
Thanks
Try this....
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
YourCustomCell *cell = (YourCustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
return cell;
}
Ok, i'm so stupid !
The UILabel doesn't show up because i add it only for iPad and i my simulator was on iPhone.
Thank for your help

I have a project where I need to use a custom UITableViewCell. I'm designing the cell as a prototype in storyboard and it looks fine there. I assign the prototype to my custom UITableViewCell subclass, give it the same reuse identifier I'm using in my UITableView and link the UILabel on the prototype cell to an IBOutlet in my UITableViewCell subclass.
When I call it from the UITableView the cell is created and if I add labels and buttons in the code of that class (create them with a CGRect and all) they all work but the labels I've added in the storyboard never show up.
I don't understand how my subclass can be called and created successfully but its layout and subviews from the storyboard don't seem to exist as far as my app is concerned. What am I doing wrong?
Here's my cellForRowAtIndexPath code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
MyTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
// Configure the cell...
return cell;
}
I've run into this issue before, and in my case, the problem was that the auto-generated code for the view controller included a call to:
[UITableView registerClass:forCellReuseIdentifier:]
I would suggest checking for and removing any calls to the above, or to
[UITableView registerNib:forCellReuseIdentifier:]
and trying your original code again.
acreichman, add casting in cellForRow and put an NSLog in you cell's awakeFromNib to see if you get there. Let me know...
Your cellForIndexViewPath should look like this, to create a simple custom cell with label,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableCell";
SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.nameLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
Make sure that you have made all connections well, set datasource and delegate to table and then set the “Identifier” of the custom cell to "MyTableViewCell" in “Attributes Inspector” like this,
For storyboard:
Add "MyTableViewCell" instead of "SimpleTableCell" as shown in above screenshot.
I'm trying to create a custom UITableViewCell via Storyboard for my iPhone App (Note: this is iOS 7).
Each cell is a bit complicated, consisting of a UIView with a few labels. In other words, I want to set up a prototype cell by customizing the content view of the cell itself.
Here are the steps I tried:
Drag a UIView into the Table View in Storyboard and set it's tag to be 1.
Added a single label to that UIView (ultimately, I will need several labels).
Implemented some basic table view methods:
As follows:
-(int)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 10;
}
- (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];
}
UIView *view = (UIView *)[cell viewWithTag:1];
NSLog(#"%#",view); //this just prints "(null)" a bunch of times
return cell;
}
Here's the hierarchy of my GUI elements.
Here is a demonstration that I have set the tag of the UIView to 1.
And here is the UITableView:
It prints out (null) many times. What is the proper way to do this? I haven't had success finding any tutorials for complex custom UITableViewCells that are built through storyboard.
I think you need to drag and drop UITableViewCell to your UITableView not UIView.
Here is the screenshot:
Who do to set a tableView Cell Identifier in a UIViewController ?
Using UITableViewController I always do it through the interface (see screenshot below)
Now I dont see that option if I use UIViewController
here's my code
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
NSString *messageAtIndexPath = [messageArray objectAtIndex :[indexPath row]];
[[cell textLabel] setText:messageAtIndexPath];
return cell;
}
please advice
Unless I add a prototype cell which messes my interface.
A couple things here:
1) A UITableViewController inherits from UIViewController (which I think is what you are actually talking about, instead of "UIControllerView"). UITableViewControllers have the ability to do prototype cells and set these identifiers...
2) ... which are case sensitive. In your screenshot, you call it "cell" while in your code you call it "Cell".
They need to be spelled exactly the same and in the same upper/lower case way.
It's not super clear what you are trying to do here, but I sense that you want to create a custom cell in your XIB or storyboard and then reference it in your "cellForRowAtIndexPath:" method. Here is a tutorial that talks about prototype cells and identifiers and using them in storyboards, and I hope this helps you out.
So I am trying to display horizontally scrollable collection view inside tableviewcell. the code i am using is
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = (UITableViewCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UICollectionViewController *cv = [self.storyboard instantiateViewControllerWithIdentifier:#"collectionViewID"];
cv.view.frame = cell.contentView.bounds;
[self addChildViewController:cv];
[cell.contentView addSubview:cv.view];
[cv didMoveToParentViewController:self];
return cell;
}
I am getting error: Object can not be nil. I'd appreciate if someone can help me out understanding the error.
I have done this in my app.
I found it much easier to subclass UITableViewCell. The I could put all the UICollectionView setup and the UICollectionView datasource and delegate inside the code for the cell.
I then provided one public property of type NSArray which I pass into the cell. The cell then uses this array as the datasource for the UICollectionView that it owns itself.
Made it a lot easier to manage.
check your UICollectionViewControlle's attribute inspector for identifier value {collectionViewID}
EDIT
[self addChildViewController:cv]; --> I think you want to add cv to the cell, isn't you?
this is Nsr (just a beginner in xcoding), using xcode 4.3.3,
I've made a Custom UITableview with Custom UITableviewcell through storyboarding,
I have a UIBUtton and a UILabel in my custom cell.
i'v remove the cell selection (also cleared the background) so that only the buttons can be accessable which works as a backgound for the custom UILabel.
Now there are bunch of buttons since of using data array, and when i click any button, it segues to the other view (detail view), all i wanted is to set the custom Label (set over the detail view) from the previous selected button with "Label"...
means new Label = previous page's clicked Label from the custom tableview..
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
Custom *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[Custom alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.myLabel.text = [myArray objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
[self.myTable reloadData];
}
I hope you get my problem, very sorry for my poor english..
Please help me, im in a real mess, coz this problem already took my 3 days :(
Thanx in advance, Cheers.
function return Custom cell but in header you write UItableviewCell change this to Custom
