xCode: TableView cant see/acces all cells - objective-c

Question

When I press a button called "AllOK" I want the object.selectedIndex to be 0. This works perfectly with the cells that is visible. But it won't acces the cells which isn't viewable on the app / screen. If you scroll down and get vision of them, it will check them, but i want it to do it, without having to scroll down.
Do anyone know how to get the tableview to know that it "also" got the cells that it cannot see?
My code for my tableview and for the button:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"FancyCell"];
cell = nil;
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"FancyCell"];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
// add the segmentedControl when you create a new cell
UIImage *correctImageGreen = [[UIImage imageNamed:#"green.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
UIImage *correctImageGul = [[UIImage imageNamed:#"gul.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
UIImage *correctImageRed = [[UIImage imageNamed:#"red.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
UIImage *correctImageGray = [[UIImage imageNamed:#"gray.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
NSArray *itemArray = [NSArray arrayWithObjects: correctImageGreen, correctImageGul, correctImageRed, correctImageGray, nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(310, 7, 150, 30);
[cell.contentView addSubview:segmentedControl];
// add an action so we can change our model if the view changes
[segmentedControl addTarget:self action:#selector(didChangeSegmentedControl:) forControlEvents:UIControlEventValueChanged];
// use a tag so we can retrieve the segmentedControl later
segmentedControl.tag = 42;
}
// either if the cell could be dequeued or you created a new cell,
// segmentedControl will contain a valid instance
UISegmentedControl *segmentedControl = (UISegmentedControl *)[cell.contentView viewWithTag:42];
UIImage *comment = [UIImage imageNamed:#"Checkmark-hvid"];
UIImage *imageRef = [UIImage imageNamed:#"Checkmark-hvid"];
UIImageView *commentView = [[UIImageView alloc] initWithImage: comment];
UIImageView *imageRefView = [[UIImageView alloc] initWithImage: imageRef];
commentView.frame = CGRectMake(625, 5, 30, 30);
imageRefView.frame = CGRectMake(515, 5, 30, 30);
commentView.tag = 98;
imageRefView.tag = 99;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
boolean_t didGetStates = [defaults boolForKey:#"didGetStates"];
MBFancyObject *object = _objects[indexPath.row];
if (didGetStates) {
// State
NSDictionary *dic = [tableData objectAtIndex:indexPath.row];
if (object.beingEdited == -1) {
int selectedState = [[dic valueForKey:#"State"] intValue];
object.selectedIndex = selectedState;
}
// Comment & ImageRef
int comment = [[dic valueForKey:#"Comment"] intValue];
int imageRef = [[dic valueForKey:#"Foto"] intValue];
if (comment == 0) {
[cell.contentView addSubview:commentView];
}
else {
[[cell.contentView viewWithTag:98]removeFromSuperview];
}
if (imageRef == 0) {
[cell.contentView addSubview:imageRefView];
}
else {
[[cell.contentView viewWithTag:99]removeFromSuperview];
}
}
cell.textLabel.text = object.title;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
segmentedControl.selectedSegmentIndex = object.selectedIndex;
object.currentIndexRow = indexPath.row;
cell.backgroundColor = [UIColor clearColor];
cell.textLabel.textColor = [UIColor whiteColor];
return cell;
}
- (IBAction)allOK:(id)sender {
for (MBFancyObject *object in _objects) {
object.selectedIndex = 0;
object.beingEdited = 0;
}
[[self tableView] reloadData];
}

So I hadn't noticed this at my first comment, but your problem here is obvious. You are not properly dequeueing cells from the cell pool, and therefore when you scroll, you are creating a brand new cell EVERY time, which causes them not to have your selected index the way you want. I am pretty sure that your solution lies right here:
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"FancyCell"];
cell = nil;
if (!cell) {
You are dequeuing a cell properly, but then immediately setting it to nil, meaning it will ALWAYS go through the !cell check and will ALWAYS create a new cell. Try removing this line and working with the dequeued cell.
Edit:
Since that didn't do it, this is what else I would try:
Create a call to the method willDisplayCell:forRowAtIndexPath:, and in this call check a boolean flag that you set to see if the segmented control at that index should be at index 0 or not. So basically whenever a cell is about to be shown, you check if it's segmented control should be set to index 0, and if it should, set it's index to 0.
