I am attempting to navigate from a TableViewCell to a detail VC indicating details about the current business that is on the cell. Here are the stub tableiewMethods:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("YelpTableBusinessCell", forIndexPath: indexPath) as! YelpTableBusinessCell
var business:Business = Business(dictionary: businessArray[indexPath.row] as! NSDictionary)
cell.business = business
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
businessToUseTVC = Business(dictionary: businessArray[indexPath.row] as! NSDictionary)
performSegueWithIdentifier("businessToDetailVC", sender: view);
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if let cell = sender as? YelpTableBusinessCell {
if segue.identifier == "businessToDetailVC" {
if let ivc = segue.destinationViewController as? AttractionsDetailViewController {
ivc.businessToUse = self.businessToUseTVC
}
}
}
}
I set two breakpoints, one at the prepareForSegue
method and one at the didSelectRowAtIndexPath
method
I initialize businessToUseVTC
variable in didSelectRowAtIndexPath
, but when I run the app, when I am at the AttractionsDetailVC, which contains this bit of code,
func loadYelpInfo() {
businessName.text = businessToUse.name
let thumbImageViewData = NSData(contentsOfURL: businessToUse.imageURL!)
thumbImage.image = UIImage(data: thumbImageViewData!)
let reviewImageData = NSData(contentsOfURL: businessToUse.ratingImageURL!)
reviewImage.image = UIImage(data: reviewImageData!)
categories.text = businessToUse.categories
reviews.text = "\(businessToUse.reviewCount!) Reviews"
distanceLabel.text = businessToUse.distance
}
the code breaks, saying that businessToUse
, set inside DetailsVC, is nil.
Any help would be greatly appreciated.
First, make sure you ctrl drag from the VIEWCONTROLLER, not the individual cell.
Second, the sender is not of type YelpTablseBusinessCell
, i believe this is your problem.
