cellForRowAtIndexPath is not getting called - ios

Question

I have a table view controller in which the cells don't show up:
I have added UiViewDataSource and UITableViewDelegate as shown below:
myViewController:UITableViewController<UITableViewDataSource,UITableViewDelegate>
In the storyboard as well as in the code I have set
self.tableView.delegate =self;
self.tableview.datasource = self;
My numberOfRowsInSection returns the value 30 (verified with logs) and numberOfSectionsInTableView returns 1 (verified with logs)
I have also printed the tableView header and footer view frame,height and width and they all have the value 0.0000
NSLog(#"The header frame size is%f" ,self.tableView.tableHeaderView.frame.size.height);
NSLog(#"The header frame size is%f" ,self.tableView.tableHeaderView.frame.size.width);
NSLog(#"The header frame size is%f" ,self.tableView.tableFooterView.frame.size.height);
NSLog(#"The header frame size is%f" ,self.tableView.tableFooterView.frame.size.width);
This is the firstController of a navigation controller.
The numberOfSectionsInTableView method is called first, then the numberOfRowsInSection and then the heightForRowAtIndexPath is called.
The cellForRowAtIndexPath method contains:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
CustomCell *cell = (CustomCell *) [self.tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
[cell configureCustomCell:[self.dataSource objectAtIndex:indexPath.row]];
return cell;
}
configureCustomCell configures the different properties in the cell.
I tried all the solutions given in similar questions but none of them seem to be working. What am I missing?

Answer 1

if you have configured UITableViewDataSource and UITableViewDelegate protocols inside your ViewController.h file, then there is no need to use self.tableView.delegate =self;
self.tableview.datasource = self;
if you have configured UITableView inside your storyboard.
you need to configure your CustomTableViewCell with your tableView's cell property.
step - 1
select your tableView Cell and inside identity inspector define your CustomTableViewCell class.
step - 2
now provide cell identifier. (i have used "customCell")
import your CustomCell class inside your ViewController.m file. Just created demo app as per your reference. Hope it solves your query.
#import "ViewController.h"
#import "CustomTableViewCell.h" //CustomTableViewCell class
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 30; //used staticCells 30
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"customCell"; //as defined in cell identifier (as per step -2)
CustomTableViewCell *cell = (CustomTableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
if (cell == nil)
{
cell = [[CustomTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
// configure your custom cell
return cell;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
