Pass cell.section to CustomTableCell - ios

Question

I have a tableview called AdminOrderViewController and it has customcell called StepperProgressCell.
This customcell has a custom UIView called AYStepperView. There is a button in this UIView and I implemented a delegate on it, whenever it gets clicked and I clicked method is getting called on AdminOrderViewController.
However, I could not able to figure out how to pass clicked header cell.section to AYStepperView ??
AdminOrderViewController.m
#interface AdminOrderViewController : UIViewController <AYStepperViewDelegate>
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"StepperProgressCell";
StepperProgressTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[StepperProgressTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
cell.stepperView.delegate= self;
return cell;
}
-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
AdminHeaderFooterView *sectionHeaderView = [self.adminTableView dequeueReusableHeaderFooterViewWithIdentifier:SectionHeaderViewIdentifier];
if (sectionHeaderView == nil)
{
sectionHeaderView = [[AdminHeaderFooterView alloc] initWithReuseIdentifier:SectionHeaderViewIdentifier];
}
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(selectHeaderAction:)];
[sectionHeaderView addGestureRecognizer:tapGesture];
return sectionHeaderView;
}
-(void) selectHeaderAction :(UITapGestureRecognizer*) gestureRecognizer
{
AdminHeaderFooterView* cell = (AdminHeaderFooterView*)gestureRecognizer.view;
[self toggleSection:cell withSection: cell.section];
// how to pass clicked section to AYStepperView??
}
-(void)clicked :(NSUInteger) currentSection
{
NSLog(#"Stepper clicked %lu", currentSection);
}
StepperProgressTableViewCell.m
#implementation StepperProgressTableViewCell
#synthesize stepperView;
- (void)awakeFromNib {
[super awakeFromNib];
[self setUpViews];
}
- (void)setUpViews {
self.stepperView = [[AYStepperView alloc]initWithFrame:CGRectMake(0, 0 , [[UIScreen mainScreen] bounds].size.width, kFormStepperViewHeight) titles:#[#"Processing",#"Ready",#"Delivered", nil)]];
[self addSubview:self.stepperView];
}
AYStepperView.h
#property (nonatomic) NSUInteger currentSection;
AYStepperView.m
#protocol AYStepperViewDelegate <NSObject>
#required
- (void)clicked :(NSUInteger) currentSection;
#end
- (void)buttonPressed:(UIButton *)sender {
[stepperDelegate clicked : currentSection];
}

Answer 1

The cell should not need to know which row or section it is in; Your table view controller can find this easily, given a reference to the cell.
Your view controller should not set itself as the delegate of the stepper view. It should be a delegate of the cell. The cell should be the delegate of the stepper view. This is a bit more complicated but it maintains better separation of concerns and makes the whole thing cleaner.
AYStepperView.h
#protocol AYStepperViewDelegate <NSObject>
#required
- (void)clicked;
#end
AYStepperView.m
- (void)buttonPressed:(UIButton *)sender {
[stepperDelegate clicked];
}
StepperProgressTableViewCell.h
#protocol StepperProgressTableViewCellDelegate <NSObject>
#required
- stepperChanged: (StepperProgressTableViewCell) cell;
StepperProgressTableViewCell.m
-(void)awakeFromNib {
self.stepperView.delegate= self;
}
- (void)clicked {
[self.delegate stepperChanged: self];
}
AdminOrderViewController.m
#interface AdminOrderViewController : UIViewController <StepperProgressTableViewCellDelegate>
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"StepperProgressCell";
StepperProgressTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[StepperProgressTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
cell.delegate= self;
return cell;
}
-(void)stepperChanged:(StepperProgressTableViewCell)cell {
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
// Now do something with indexPath.section
}

Answer 2

in cellForRowAtIndexPath set section to stepper view
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"StepperProgressCell";
StepperProgressTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[StepperProgressTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
cell.stepperView.delegate= self;
cell.stepperView.currentSection = indexPath.section;//set section value
return cell;
}
