    MultipleContCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(!cell)
    {
        cell = [[MultipleContCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }
    switch (indexPath.section) {
        case 0:
        {
             NSArray *arr_email =[_dict_contact objectForKey:@"u_email"];
            cell.detail_lbl.text =[arr_email objectAtIndex:indexPath.row];
              return cell;
        }
            break;
        case 1:
        {
            NSArray *arr_phone =[_dict_contact objectForKey:@"u_phone"];
            cell.detail_lbl.text =[arr_phone objectAtIndex:indexPath.row];
              return cell;
        }

Make sure that

  1. numberOfSectionsInTableView returns value > 0
  2. numberOfRowsInSection returns value > 0
  3. UITableView frame > 0

You need to call registerNib: forCellReuseIdentifier or registerClass:forCellReuseIdentifier for MultipleContCell inside viewdidload. For example:

[_yourTableView registerNib:[UINib nibWithNibName:@"MultipleContCell" bundle:nil] forCellReuseIdentifier:@"MultipleContCell"];

You must declare your ViewController as UITableViewDelegate and UITableViewDataSource. Something like this:

@interface MyViewController : UIViewController<UITableViewDelegate, UITableViewDataSource>

Check :

1) The numberOfSectionsInTableView is not returning 0.

2)UITableview frame is correct because cellForRowAtIndexPath would not be called is when the size or positioning of the table does not require any rows to be displayed.
