this is my code for adding tableview

UITableViewCell * cell;
SimpleTableIdentifier = #"SimpleTableIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier: nil];
if(cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier];
// Configure the cell...
UIView* bgview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
bgview.opaque = YES;
bgview.backgroundColor = [UIColor colorWithRed:(224/255.0) green:(230/255.0) blue:(241/255.0) alpha:1];
[cell setBackgroundView:bgview];
UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(0, 44, 320, 1)];
separatorLineView.backgroundColor = [UIColor colorWithRed:(74/255.0) green:(89/255.0) blue:(138/255.0) alpha:1];// you can also put image here
[cell.contentView addSubview:separatorLineView];
}
return cell;
}

Answer 1

USE
cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];
Try
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *SimpleTableIdentifier;
UITableViewCell * cell;
SimpleTableIdentifier = #"SimpleTableIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier];
if(cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier];
UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(0, 42, 320, 1)];
[separatorLineView setTag:1];
[cell.contentView addSubview:separatorLineView];
UIView* bgview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
bgview.opaque = YES;
bgview.backgroundColor = [UIColor colorWithRed:(224/255.0) green:(230/255.0) blue:(241/255.0) alpha:1];
[cell setBackgroundView:bgview];
}
UIView *SPview=[cell viewWithTag:1];
SPview.backgroundColor = [UIColor blueColor];// you can also put image here
return cell;
}
The problem is the frame you set for the view I changed it from 44 to 42 for the seperator line orgin and now it works fine

Answer 2

Move the configuring of the cell outside of
if (cell == nil) {
cell = [tableView dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
}
// everything else
should do the trick.

Answer 3

Use it
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *SimpleTableIdentifier;
UITableViewCell * cell;
SimpleTableIdentifier = #"SimpleTableIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier: nil];
if(cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier];
}
// Configure the cell...
UIView* bgview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
bgview.opaque = YES;
bgview.backgroundColor = [UIColor colorWithRed:(224/255.0) green:(230/255.0) blue:(241/255.0) alpha:1];
[cell setBackgroundView:bgview];
UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(0, 44, 320, 1)];
separatorLineView.backgroundColor = [UIColor colorWithRed:(74/255.0) green:(89/255.0) blue:(138/255.0) alpha:1];// you can also put image here
[cell.contentView addSubview:separatorLineView];
return cell;
}

Answer 4

Your problem is you're not configuring your cell each time you get a new one. You should populate your cell each time cellForRowAtIndexPath is called.
Try changing your code to:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *SimpleTableIdentifier;
UITableViewCell * cell;
SimpleTableIdentifier = #"SimpleTableIdentifier";
cell = [tableView dequeueReusableCellWithIdentifier: nil];
if(cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier];
}
// Configure the cell...
UIView* bgview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 1)];
bgview.opaque = YES;
bgview.backgroundColor = [UIColor colorWithRed:(224/255.0) green:(230/255.0) blue:(241/255.0) alpha:1];
[cell setBackgroundView:bgview];
UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(0, 44, 320, 1)];
separatorLineView.backgroundColor = [UIColor colorWithRed:(74/255.0) green:(89/255.0) blue:(138/255.0) alpha:1];// you can also put image here
[cell.contentView addSubview:separatorLineView];
return cell;
}

Answer 5

Good answer at here.
First add separator thru the xib file and than put this code in cellForRowAtIndexPath.
tableView.tableFooterView = [[[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 10.0f)] autorelease];
