can't retrieve indexPath on prepareforsegue? - swift

Question

I'm having a problem with retrieving the indexPath on prepareForSegue with the "comments" block. The comments button is inside the cell, and I created a segue from the view controller to the desired vc but every time I click the button, I get an "unexpectedly found nil while unwrapping an optional value" on the part where I declare the indexPath.
override func shouldPerformSegueWithIdentifier(identifier: String?, sender: AnyObject?) -> Bool {
if (identifier == "webPage1") {
let indexPath: NSIndexPath = tableView.indexPathForSelectedRow()!
if (arrayByVotes[indexPath.row].objectForKey("videoURL") as NSString == "") {
performSegueWithIdentifier("comments", sender: nil)
return false
}
}
return true
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "webPage1") {
var urlToOpen:String = ""
let indexPath: NSIndexPath = tableView.indexPathForSelectedRow()!
if((arrayByVotes[indexPath.row].objectForKey("videoURL")) != nil) {
urlToOpen = arrayByVotes[indexPath.row].objectForKey("videoURL") as String
urlToOpen = urlToOpen.stringByReplacingOccurrencesOfString("http:", withString: "https:", options: .LiteralSearch, range: nil)
}
let sW: webpageViewController = segue.destinationViewController as webpageViewController
sW.urlPath = urlToOpen
} else if (segue.identifier == "comments") {
let indexPath: NSIndexPath = tableView.indexPathForSelectedRow()!
let sweet:PFObject = arrayByVotes[indexPath.row] as PFObject
var postId = sweet.objectId
let selectedFContent: String = arrayByVotes[indexPath.row].objectForKey("content") as String
let fpvc: FeedPageViewController = segue.destinationViewController as FeedPageViewController
fpvc.selectedFeedFeedContent = selectedFContent
fpvc.ourpostId = postId
}
}
I then tried wrapping it in an
if let indexPath = tableView.indexPathForSelectedRow()!
but that didn't work either as it wouldn't retrieve the correct indexPath every time.
Essentially the program is supposed to check to see if a cell contains a URL. If it does, it calls the vc with a webview, and if not, then it directly calls the comments page.

Try this
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if (segue.identifier == "webPage1") {
let selectedRow = tableView.indexPathForSelectedRow()?.row
var urlToOpen = arrayByVotes(selectedRow!) as? String
if((urlToOpen != nil) {
urlToOpen = urlToOpen.stringByReplacingOccurrencesOfString("http:", withString: "https:", options: .LiteralSearch, range: nil)
}
let sW: webpageViewController = segue.destinationViewController as webpageViewController
sW.urlPath = urlToOpen
} else if (segue.identifier == "comments") {
let selectedRow = tableView.indexPathForSelectedRow()?.row
let sweet:PFObject = arrayByVotes(selectedRow!) as PFObject
var postId = sweet.objectId
let selectedFContent: String = arrayByVotes(selectedRow!).objectForKey("content") as String
let fpvc: FeedPageViewController = segue.destinationViewController as FeedPageViewController
fpvc.selectedFeedFeedContent = selectedFContent
fpvc.ourpostId = postId
}
}
