iOS Segue opening two view controllers (assuming two table cells clicked) - ios

Question

When I click a table cell in my application it opens two view controllers. Which it seems to assume that I have clicked two cells, since it opens the cell before and the one I have clicked.
The first 3 cells are pretty much static, every other cell underneath the "ingredients" heading are dynamic. Hence why indexPath - 3
I created the segue between the table view and the view controller in the interface builder.
Table View:
First view controller/segue:
Second view controller segue:
Code for the segue:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
self.selectedIngredient = self.selectedProduct.ingredientsArray[indexPath.row - 3];
[self performSegueWithIdentifier:#"ingViewSegue" sender:self];
NSLog(#"selected ingredient %#", self.selectedIngredient);
}
#pragma mark segue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
IngredientWebViewController *webView = segue.destinationViewController;
webView.selectedIngredient = self.selectedIngredient;
}
Number of rows in table:
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [_selectedProduct.ingredientsArray count] + 3;
}
Code to populate table:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexPath.row == 0)
{
TitleCell* titleCell = (TitleCell*)[self.tableView dequeueReusableCellWithIdentifier:#"TitleCell" forIndexPath:indexPath];
titleCell.nameLabel.text = self.selectedProduct.productName;
titleCell.brandLabel.text = self.selectedProduct.productBrand;
return titleCell;
}
else if(indexPath.row == 1)
{
return [self.tableView dequeueReusableCellWithIdentifier:#"RatingCell" forIndexPath:indexPath];
}
else if(indexPath.row == 2)
{
return [self.tableView dequeueReusableCellWithIdentifier:#"IngredientHeaderCell" forIndexPath:indexPath];
}
else
{
IngredientsCell* ingCell = (IngredientsCell*)[self.tableView dequeueReusableCellWithIdentifier:#"IngredientCell" forIndexPath:indexPath];
ingCell.ingredientNameLabel.text = self.selectedProduct.ingredientsArray[indexPath.row - 3];
if([self.selectedProduct.ratingsArray[indexPath.row -3] isEqual: #"4"])
{
ingCell.ingredientsImage.image = [UIImage imageNamed:#"icon_safe.png"];
}
else if([self.selectedProduct.ratingsArray[indexPath.row -3] isEqual: #"3"])
{
ingCell.ingredientsImage.image = [UIImage imageNamed:#"icon_low.png"];
}
else if([self.selectedProduct.ratingsArray[indexPath.row -3] isEqual: #"2"])
{
ingCell.ingredientsImage.image = [UIImage imageNamed:#"icon_med.png"];
}
else if([self.selectedProduct.ratingsArray[indexPath.row -3] isEqual: #"1"])
{
ingCell.ingredientsImage.image = [UIImage imageNamed:#"icon_high.png"];
}
else
{
ingCell.ingredientsImage.image = [UIImage imageNamed:#"icon_safe.png"];
}
return ingCell;
}
}
Code to alter cell height:
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(indexPath.row == 0)
{
UITableViewCell* cell = [self.tableView dequeueReusableCellWithIdentifier:#"TitleCell"];
CGSize size = [cell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
return size.height + 1;
}
else if(indexPath.row == 1)
{
UITableViewCell* cell = [self.tableView dequeueReusableCellWithIdentifier:#"RatingCell"];
CGSize size = [cell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
return 118;
}
else if(indexPath.row == 2)
{
UITableViewCell* cell = [self.tableView dequeueReusableCellWithIdentifier:#"IngredientHeaderCell"];
CGSize size = [cell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
return size.height + 1;
}
else
{
UITableViewCell* cell = [self.tableView dequeueReusableCellWithIdentifier:#"IngredientCell"];
CGSize size = [cell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
return 60;
}
}

A segue will be performed automatically while a cell is tapped. Try the following code:
// - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
// {
// self.selectedIngredient = self.selectedProduct.ingredientsArray[indexPath.row - 3];
// [self performSegueWithIdentifier:#"ingViewSegue" sender:self];
// NSLog(#"selected ingredient %#", self.selectedIngredient);
// }
#pragma mark segue
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];
IngredientWebViewController *webView = segue.destinationViewController;
webView.selectedIngredient = self.selectedProduct.ingredientsArray[indexPath.row - 3];
}
