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

I am doing using some code that I have seen work before. Essentially a user answers yes or no on a post with some buttons. Pressing yes or no updates the database, which is working correctly, and it also updates the visible UI, which is not working. This UI updates the buttons so they one is selected, other is highlighted and both are disabled for user interaction. Also it makes changes to two UILabels. The method that these buttons calls needs to update the database and retrieve the buttons from the tableViewCell and update the changes I have the methods working in another ViewController so I can not understand the difference here. Here is my cellForRowAtIndexPath
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *simpleTableIdentifier = [NSString stringWithFormat:#"%ld,%ld",(long)indexPath.section,(long)indexPath.row];
NSLog(#" simple: %#",simpleTableIdentifier);
if (indexPath.row==0) {
ProfileFirstCell *cell = [self.tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
cell = [[ProfileFirstCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:simpleTableIdentifier];
}
cell = [self createProfileCell:cell];
return cell;
}else{
YesNoCell *cell =[self.tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell==nil) {
cell=[[YesNoCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell = [self createYesNoCell:cell:indexPath];
return cell;
}
}
Essentially what this does is create the users profile in the first cell, and load all the questions that user asks. This is the major difference I see between the old tableView and this tableView. In createYesNoCell I create the UIElements and create tags as follows
cell.yesVoteButton.tag=indexPath.row+ yesVoteButtonTag1;
cell.noVoteButton.tag=indexPath.row+ noVoteButtonTag1;
cell.yesCountLabel.tag=indexPath.row+ yesCountLabelTag1;
cell.noCountLabel.tag=indexPath.row+ noCountLabelTag1;
The buttons have the selector that initiates a number of things. It finds which button was pressed by the following.
NSInteger index;
if(sender.tag>=yesVoteButtonTag1){
NSLog(#"Yes button pressed");
votedYes=true;
index=sender.tag-yesVoteButtonTag1;
}else{
NSLog(#"No button Pressed");
votedYes=false;
index=sender.tag-noVoteButtonTag1;
}
UILabel *yesLabel = (UILabel*) [self.tableView viewWithTag:index+yesCountLabelTag1]; // you get your label reference here
UIButton *yesButton=(UIButton *)[self.tableView viewWithTag:index+1+yesVoteButtonTag1];
NSLog(#"Tag IN METHOD: %ld",index+yesVoteButtonTag1);
UILabel *noLabel = (UILabel*) [self.tableView viewWithTag:index+1+noCountLabelTag1]; // you get your label reference here
UIButton *noButton=(UIButton *)[self.tableView viewWithTag:index+noVoteButtonTag1];
These viewWithTag calls are nil when I look at them. The only difference that I can see from my earlier implementation is that the old one had sections and one row, while this one is all rows and one section. So replacing the indexPath.section with indexPath.row should account for that. Also I checked that the tag made in cellForRowAtIndexPath is the same as the row recovered in the yes/no vote method, because it is displaced by one because of the profile cell being created at indexPath.row==0. I tried passing the cell to the yes/no vote method and tried to recover the buttons and labels with contentView as some suggestions made on similar posts. However this didn't seem to solve my problem. Really would appreciate some insight on this.
have you call the '[tableView reload]' method to update the UITableView, it may helps.
Firstly, the table reuse identifier should be used for types of cells, not one for each cell. You have two types, so you should use two fixed reuse identifiers.
ProfileFirstCell *cell = [self.tableView dequeueReusableCellWithIdentifier:#"ProfileCell"];
if (cell == nil) {
cell = [[ProfileFirstCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:#"ProfileCell"];
}
and
YesNoCell *cell =[self.tableView dequeueReusableCellWithIdentifier:#"YesNoCell"];
if (cell==nil) {
cell=[[YesNoCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"YesNoCell"];
}
Secondly, rather than trying to get a reference to a cell after creating the table, which isn't working for you, you should initialize the cells completely when they are created. (TableView won't create cells unless they're visible, so you shouldn't rely on their existing at all.)
createProfileCell should really be called initializeProfileCell, because you're not creating the cell in it - you already did that in the line above, or recovered an old one.
Then your call to initializeProfileCell can take a flag specifying whether it is a Yes or No cell and set its properties accordingly.
cell = [self initializeProfileCell:cell isYes:(indexPath.section==0)];
Similarly with createYesNoCell --> initializeYesNoCell.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"YOURCELL_IDENTIFIER";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
UILabel *title = (UILabel*) [cell viewWithTag:5];
UILabel *vensu =(UILabel*) [cell viewWithTag:7];
vensu.text = #"YOUR TEXT";
title.text = #"YOUR TEXT";
return cell;
}
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'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:
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?
I have two kind of cell, one a standard title-subtitle cell, and another custom cell with two UITextField. And they have different identifier, VIEW and EDIT.
In my code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
I need to create two kind of cell. At any time, I have only one cell in edit, so I create a NSUInteger to keep track of which cell is being edited.
My code looks like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell* cell;
if ( rowInEdit == indexPath.row )
{
cell = [tableView dequeueReusableCellWithIdentifier:#"EDIT"];
if ( !cell )
{
cell = [[UITableViewCell alloc]init];
}
RLSite* site = [[RLSettings settings]siteAtIndex:indexPath.row];
[[cell textLabel]setText:site.name];
[[cell detailTextLabel]setText:site.url];
}
else
{
cell = [tableView dequeueReusableCellWithIdentifier:#"VIEW"];
if ( !cell )
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"VIEW"];
}
RLSite* site = [[RLSettings settings]siteAtIndex:indexPath.row];
[[cell textLabel]setText:site.name];
[[cell detailTextLabel]setText:site.url];
}
return cell;
}
Notice that my first part is definitely flawed. I don't know how to create a cell with prototype, and how to assign reuseIdentifier to it. Furthermore, I don't know how to access those UITextField in that cell once it's created.
Can anyone help me?
e. how to create a cell with prototype you can follow these tutorials as I also learned it from one of these tutorials

And to excess the added text views you need to assign them tag values (obviously distinct).
Then use the below code to excess them in side your tableView:cellForRowAtIndexPath: method.
UITextField *txtField = (UITextField *)[cell viewWithTag:8];
Here replace the 8 with your tag value :)
