So I have a setup like this:
Where I have a custom code reader view controller, and as soon as it detects a barcode, I want it to segue to another view controller with a label and a UIWebView. So far, it works perfectly with just the label being displayed. For some reason, all I did was add a UIWebView
and added an IBOutlet
in my Second View Controller custom class and the segue won't work due to the exc_bad_access
error. The error highlights the following line in my code reader view controller:
self.performSegueWithIdentifier("push", sender: self) //my segue is named push
Here is my second view controller code:
import UIKit
public class SecondViewController: UIViewController {
var setText:String!
@IBOutlet weak var WebV: UIWebView!
@IBOutlet var label: UILabel!
override public func viewDidLoad() {
label.text = setText
}
}
SOLUTION: So I just realized that, for some reason, my segue was running off the main thread. Does this happen in a closure? And, does this mean that you can't perform a segue in a closure/block?
Any help is greatly appreciated. Thank you so much.
So I just realized that, for some reason, my segue was not running on the main thread. Dispatching to the main queue fixed the issue.
