UIImagePickerController arresta l'app | Swift3, Xcode8

Question

FYI: Sono nuovo di Swift, quindi questo potrebbe essere un problema molto semplice, ma non riesco a capirlo.

Ho seguito il tutorial Start Developing iOS Apps (Swift) utilizzando la versione beta Xcode 8 e Swift 3.

ho attaccato un riconoscitore Toccare gesto ad un Punto di vista e poi aggiunto questa azione nel ViewController.swift:

@IBAction func selectImageFromPhotoLibrary(_ sender: UITapGestureRecognizer) { 
     // Hide the keyboard. 
     nameTextField.resignFirstResponder() 

     // UIImagePickerController is a view controller that lets a user pick media from their photo library. 
     let imagePickerController = UIImagePickerController() 

     // Only allow photos to be picked, not taken. 
     imagePickerController.sourceType = .photoLibrary 

     // Make sure ViewController is notified when the user picks an image. 
     imagePickerController.delegate = self 

     present(imagePickerController, animated: true, completion: nil) 
    } 

Quando l'azione selectImageFromPhotLibrary viene richiamata da un tocco sulla visualizzazione dell'immagine, l'app si arresta in modo anomalo senza mostrare ImagePicker.

immagino che il problema è con il nuovo presente anziché presentViewController introdotto nel Swift 3

ViewController.swift

import UIKit 

class ViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate { 

    // MARK: Properties 
    @IBOutlet weak var mealNameLabel: UILabel! 
    @IBOutlet weak var nameTextField: UITextField! 
    @IBOutlet weak var photoImageView: UIImageView! 


    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 

     // Handle the text field´s user input through delegate callbacks 
     nameTextField.delegate = self 
    } 

    // MARK: UITextFieldDelegate 
    func textFieldShouldReturn(_ textField: UITextField) -> Bool { 
     // Hide the keyboard. 
     textField.resignFirstResponder() 
     return true 
    } 

    func textFieldDidEndEditing(_ textField: UITextField) { 
     mealNameLabel.text = textField.text 
    } 

    // MARK: UIImagePickerControllerDelegate 
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) { 
     // Dismiss the picker if the user canceled. 
     dismiss(animated: true, completion: nil) 
    } 

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) { 
     // The info dictionary contains multiple representations of the image, and this uses the original. 
     let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage 

     // Set photoImageView to display the selected image. 
     photoImageView.image = selectedImage 

     // Dismiss the picker. 
     dismiss(animated: true, completion: nil) 
    } 


    // MARK: Actions 

    @IBAction func selectImageFromPhotoLibrary(_ sender: UITapGestureRecognizer) { 
     // Hide the keyboard. 
     nameTextField.resignFirstResponder() 

     // UIImagePickerController is a view controller that lets a user pick media from their photo library. 
     let imagePickerController = UIImagePickerController() 

     // Only allow photos to be picked, not taken. 
     imagePickerController.sourceType = .photoLibrary 

     // Make sure ViewController is notified when the user picks an image. 
     imagePickerController.delegate = self 

     present(imagePickerController, animated: true, completion: nil) 
    } 

    @IBAction func setDefaultLabelText(_ sender: UIButton) { 
     mealNameLabel.text = "Default Text" 
    } 


}

Answer 1

aggiungere questa chiave al tuo info.plist,

Key : Privacy - Photo Library Usage Description [ NSPhotoLibraryUsageDescription ] 
String Value : We need access to your camera roll and photo library, so that we can do operations on it. [ Customise it in your own way] 

Questo è tutto, Clean & Run il progetto.

Answer 2

in Xcode 8 nuova chiave viene aggiunta Privacy Per -

Media, Location, Fototeca, Promemoria, Movimento, calendario, Bluetooth, HomeKit, macchina fotografica, Contatti ecc .. e valore è la descrizione per la privacy a cui accederai. Per es. "Abbiamo bisogno di accedere all'utilizzo della libreria fotografica per far funzionare le funzionalità" o ANY_YOUR_APP_RELATED_DESCRIPTION.

Answer 3

notato un tasto della fotocamera e il valore necessari per l'uso della macchina fotografica pure.

tasti necessari sia per la fotocamera e fototeca che hanno bisogno di essere nella info.plist:

<key>NSCameraUsageDescription</key> 
<string>Access needed to use your camera.</string> 

<key>NSPhotoLibraryUsageDescription</key> 
<string>Access needed to photo gallery.</string> 

Answer 4

Ho provato ad aggiungere i messaggi sulla privacy, ma coloro che non ha funzionato per me. Poi ho esaminato l'ispettore degli attributi per l'elemento immagine stesso e ho selezionato la casella "Interazione utente abilitata", che era stata precedentemente deselezionata. Dopo aver fatto questo, il picker ha funzionato. Spero che aiuti qualcuno.
