So if the image picker appears and I cancel, everything is fine. However, when I choose an image, and the image picker view dismisses, I can’t select the “pick” button again, it won’t work or print anything to the console. I have no idea why. Here’s my code:

`class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {  
@IBOutlet weak var imagePickerView: UIImageView!

```
@IBAction func pickAnImage(sender: AnyObject) {
    selectImageSourceAlert()
    print("test")
}

override func viewDidLoad() {
    super.viewDidLoad()
}

func selectImageSourceAlert() {
    let alert = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)
    let userLibrary = UIAlertAction(title: "Photo Library", style: .Default) {
        _ in
        self.presentImagePicker(pickerStyle: .PhotoLibrary)
    }
    let useCamera = UIAlertAction(title: "Camera", style: .Default) {
        _ in
        // TODO: Check if camera isn't available, skip action
        let x = UIImagePickerController.isSourceTypeAvailable(.Camera)
        print(x)
        if x {
            self.presentImagePicker(pickerStyle: .Camera)
        } else {
            print("No camera available")
        }
        
    }
    let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
    
    alert.addAction(userLibrary)
    alert.addAction(useCamera)
    alert.addAction(cancelAction)
    
    presentViewController(alert, animated: true, completion: nil)
}

func presentImagePicker(pickerStyle style: UIImagePickerControllerSourceType) {
    let imagePicker = UIImagePickerController()
    imagePicker.sourceType = style
    imagePicker.allowsEditing = true
    imagePicker.delegate = self
    
    self.presentViewController(imagePicker, animated: true, completion: nil)
}

// MARK: - ImagePicker Protocol

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    
    if let image = info["UIImagePickerControllerEditedImage"] as? UIImage {
        imagePickerView.image = image
    }
    
    dismissViewControllerAnimated(true, completion: nil)
}

```

}

Hope you guys can help as I’ve been coming back to this for the past 2 days and still can’t figure it out.

I don’t know if this will help, but when I remove this code:

`if let image = info["UIImagePickerControllerEditedImage"] as? UIImage { imagePickerView.image = image }`

Everything works again. But when I add it back, the button’s function doesn’t work again.

Using your class and with a simple storyboard everything went fine. Can we have a screenshot of your storyboard or even of your app in your device ?

Update:

So I added a regular button at the top right corner and that one works even after adding an image. My suspicion is my first button doesn’t work because it is a UIBar Button Item. Here’s an image that might be helpful (made the image background red for clarity):

Any idea how to fix it with these additional insight?

Well, that is pretty weird to have the `UIBarButtonItem` disabled… If your project is not too personal or if you can reduce the issue to a test subject with only this ViewController, upload it and I’ll give it a look
