I am writing a basic photo app that allows a user to push a "+" button in a navigation controller and then an ActionSheet pops up from the bottom giving the user options, here is a picture:
I have the code to get this app working using normal buttons, but when I added it to my code for this app it crashes. Here is the code:
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate
{
#IBOutlet weak var imageView: UIImageView!
#IBAction func addPhoto(sender: UIBarButtonItem)
{
let photoOption = UIAlertController(title: nil, message: "Select an Input Type", preferredStyle: .ActionSheet)
let photoLibraryAction = UIAlertAction(title: "Photo Library", style: .Default) { (alert: UIAlertAction!) -> Void in
println("Photo Library Selected") // Used for debugging
// This code worked in my previous app
let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .PhotoLibrary
self.presentViewController(picker, animated: true, completion: nil)
}
let cameraAction = UIAlertAction(title: "Camera", style: .Default) { (alert: UIAlertAction!) -> Void in
println("Camera Selected") // Used for debugging
// This code worked in my previous app
let picker = UIImagePickerController()
picker.delegate = self
picker.sourceType = .Camera
self.presentViewController(picker, animated: true, completion: nil)
}
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
photoOption.addAction(photoLibraryAction)
photoOption.addAction(cameraAction)
photoOption.addAction(cancelAction)
self.presentViewController(photoOption, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController!, didFinishPickingMediaWithInfo info: [NSObject: AnyObject]!)
{
imageView.image = info[UIImagePickerControllerOriginalImage] as? UIImage
dismissViewControllerAnimated(true, completion: nil)
}
}
and the strange thing is after I ran this and the app crashed, I reverted back to when the code was working and the app still crashed.

The problem is that you are running this code in the simulator. But the simulator has no camera. It's just a simulator!
Hence, trying to summon an image picker controller with a .Camera source type causes an exception - with a helpful error message in the console that you could have read, thus avoiding wasting bandwidth with this question...
