Nested UITableViewController does not show any cells - ios

Question

I've added a UITableViewController to my main view controller using method from Apple docs:
- (void)viewWillAppear:(BOOL)animated {
myTableViewController = [MyTableViewController new];
[self displayContentController:myTableViewController];
}
- (void)displayContentController:(UIViewController *)viewController; {
[self addChildViewController:viewController];
viewController.view.frame = self.view.bounds;
[self.view addSubview:viewController.view];
[viewController didMoveToParentViewController:self];
}
and I wanted to display some example cells in this controller:
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:#"Cell"];
(I don't think I need any more configuration as it is UITableViewController, not UITableView)
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
cell.textLabel.text = #"Under development";
return cell;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 5;
}
But all I can see is just empty cells (I've also tried to change background color to make sure it's not just the while label color):
After few hours I have no idea what I did wrong. Do you have any idea what am I missing?

Answer 1

You have to used it:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:#"cell"];
if(!cell)
{
cell=[[UITableViewCell alloc]init];
}
cell.backgroundColor = [UIColor clearColor];
cell.textLabel.text = #"Under development";
return cell;
}

Try it:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return Table_Arr.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:#"subwaysurfer"];
if(!cell)
{
cell=[[UITableViewCell alloc]init];
}
UIImageView *imgg;
UILabel *txt;
UIImageView *Acc_img;
imgg=[[UIImageView alloc]initWithFrame:CGRectMake(10,5, 50, 50)];
imgg.image = [UIImage imageNamed:[imageArr objectAtIndex:indexPath.row]];
cell.highlighted=YES;
cell.backgroundColor=[UIColor clearColor];
txt=[[UILabel alloc]initWithFrame:CGRectMake(20, 0, self.view.frame.size.width-80, 60)];
txt.numberOfLines = 3;
txt.text=[Table_Arr objectAtIndex:indexPath.row];
txt.backgroundColor=[UIColor clearColor];
// txt.textColor=[UIColor colorWithRed:66.0/255.0 green:51.0/255.0 blue:57.0/255.0 alpha:1.0];
txt.textColor=[UIColor colorWithRed:44.f/255.f green:78.f/255.f blue:134.f/255.f alpha:1];
txt.font=[UIFont fontWithName:#"AvenirNextCondensed-Medium" size:16.0];
Acc_img=[[UIImageView alloc]initWithFrame:CGRectMake(self.view.frame.size.width-40, 20, 20, 20)];
Acc_img.image=[UIImage imageNamed:#"arrow.png"];
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad){
imgg.frame = CGRectMake(10, 5, 80, 80);
txt.frame = CGRectMake(120, 10, self.view.frame.size.width-160, 70);
Acc_img.frame = CGRectMake(self.view.frame.size.width-80, 25, 40, 40);
txt.font=[UIFont systemFontOfSize:28.0];
}
[cell addSubview:imgg];
[cell addSubview:txt];
[cell.contentView addSubview:Acc_img];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
}
// fixed font style. use custom view (UILabel) if you want something different
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad){
return 90;
}
else{
return 60;
}
}
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section{
return [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 0)];
}

Ok, problem solved. It appears, that even using UITableViewController which has built-in property tableView it is necessary to initialise the tableView (or at least it did help me).
self.tableView = [UITableView new];
