Two ways to load custom UITableViewCell from nib

Create a custom class subclassing UITableViewCell. Make sure to check the nib check box.
Add desired controls on the nib and link them with outlets.

Method 1:

Set identifier of table view cell object in Interface Builder to the identifier, that is to be used in code to make object of cells.
Write following code in cellForRowAtIndexPath method:

CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
 if (cell == nil)
 {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@”iCodeBlogCustomCell” owner:nil options:nil];
 for(id currentObject in topLevelObjects)
{
if([currentObject isKindOfClass:[CustomCell class]])
{
cell = (CustomCell *)currentObject;  break;
}
}
}

Method 2:

Create a custom init method in custom cell view class with following code:

- (id)init
{
self = [[[[NSBundle mainBundle] loadNibNamed:@"NibName" owner:self options:nil] objectAtIndex:0] retain];
if (self)
{
// any further initialization
}
return self;
}

Write following code in cellForRowAtIndexPath method:

static NSString *CellIdentifier = @"CustomCell";
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[[CustomCell alloc] init] autorelease];
}
 // setup your cell
 return cell;
