change static UITableViewCell background color inside a UIPopoverController xcode5 - objective-c

Question

I'm developing an app for iOS7.1 in Xcode 5
And I want to change tableview cell's background color at the final row to look like this
but when I call this UITableViewController inside a UIPopoverController I get this:
Somehow my tableview cell lost it's original background color
this is my code:
//iPad Popover Section
if (!resultBTPopover || !resultBTPopover.popoverVisible)
{
ResultadosBalanceTransferVC *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"ResultadosBalanceTransferVC"];
//controller.delegate = self;
controller.title = #"Resultados";
controller.amountValue = self.amountTextfield.text;
controller.promoRateValue = self.promoRateTextfield.text;
controller.normalRateValue = self.normalRateTextfield.text;
controller.otherBankRateValue = self.otherBankRateTextfield.text;
controller.termValue = self.termTextfield.text;
navController = [[UINavigationController alloc]initWithRootViewController:controller];
navController.toolbarHidden = FALSE;
NSDictionary *textAtributesDictionaryTitle = [NSDictionary dictionaryWithObjectsAndKeys:
UIColorFromRGB(toolbarTintColor), NSForegroundColorAttributeName,
[UIFont fontWithName:#"HelveticaNeue-BoldCond" size:19.0f], NSFontAttributeName,
nil];
[navController.navigationBar setTitleTextAttributes:textAtributesDictionaryTitle];
resultBTPopover = [[UIPopoverController alloc] initWithContentViewController:navController];
[resultBTPopover presentPopoverFromRect:CGRectMake(self.view.center.x - (self.view.center.x * .2734), self.view.center.y - (self.view.center.y * .6510), 300, 400)
inView:self.view permittedArrowDirections:0
animated:YES];
}
else{
[resultBTPopover dismissPopoverAnimated:YES];
resultBTPopover = nil;
}
}
how to get my original tableview cell colors???
thanks in advance for the support
EDIT: I'll put method proposed by Plokstorm
ResultsCell.h:
#import <UIKit/UIKit.h>
#interface ResultsCell : UITableViewCell
#property (nonatomic, weak) IBOutlet UILabel *label1;
#property (nonatomic, weak) IBOutlet UILabel *label2;
#property (nonatomic, weak) IBOutlet UILabel *label3;
#property (nonatomic, weak) IBOutlet UILabel *label4;
#property (nonatomic, weak) IBOutlet UILabel *label5;
#end
on STORYBOARD I did this:
all of them changed to ResultsCell custom class
linked all the properties with visual labels of the UITableViewCell
on CODE I did this for testing:
ResultadosBalanceTransferVC.m
#import "ResultsCell.h"
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
ResultsCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil) {
cell = [[ResultsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell"];
}
if (indexPath.row == 2){
cell.backgroundColor = [UIColor redColor];
cell.label1.text = #"Pago Total";
}
return cell;
}
and... still getting same result:

Answer 1

Show us your
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
You can change a cell background with cell.backgroundColor.

Answer 2

Try that:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell"];
}
if (indexPath.row == 2)
cell.backgroundColor = [UIColor redColor];
return cell;
}

Answer 3

You need to change cell class with it in storyboard.
If you don't create a cell class, you should create an object which extends UITableViewCell. Then you can add its property.
#interface ResultsCell : UITableViewCell
#property (nonatomic, weak) IBOutlet UILabel *lYourFirstLabel;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
ResultsCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil) {
cell = [[ResultsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell"];
}
if (indexPath.row == 2)
cell.backgroundColor = [UIColor redColor];
[cell.lYourFirstLabel setText:#"hello"];
return cell;
}
