So I'm having issues with the tap gesture for the "Work with View Controllers" section of the tutorial. I'm not getting the image picker to show up when i sumlate or run the app on an iPhone. I think the code is right, because its nearly identical to the sample. I've also rebuilt the app from the beginning of that section 4 or 5 times. I'm pretty sure the @IBOutlet and @IBAction are correctly connected because they have the filled grey circles next to them, but for some reason it won't work. However, I can correctly run the sample. Can anyone think of some issues that might be throwing me off?
import UIKit
class ViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
// MARK: Properties
@IBOutlet weak var nameTextField: UITextField!
@IBOutlet weak var mealNameLabel: UILabel!
@IBOutlet weak var photoImageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// 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.
dismissViewControllerAnimated(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.
dismissViewControllerAnimated(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
presentViewController(imagePickerController, animated: true, completion: nil)
}
@IBAction func setDefaultLabelText(sender: UIButton) {
mealNameLabel.text = "Default Text"
}
}
