How do I go to the next screen after pressing "Use Photo" in Swift?

Question

I am currently creating a simple app in Swift for an iPhone. When the I press the button "Take Photo" the camera opens up, so I can take a picture. Then when I press "Use Photo", it just stays on the first screen with the "Take Photo" button. How do I get the app to show the next screen/storyboard after pressing "Use Photo"?

Answer 1

On your home screen there are two buttons...

1. Take Photo
2. Use Photo

So when you click on Take photo, it opens camera & you're able to capture photo alright.

Now when you're on home screen, when you press Use Photo button, it doesn't go to image library right.

So from this, scenario onwards, I'll provide you solution to use photo.

Solution : Please go through this, here I'm using image-picker on button click. It will allow you to select/choose image and assign your selected image to a UIImageView.

import UIKit

class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet weak var imageView: UIImageView!


    @IBAction func btnUsePhoto(_ sender: Any) {
        let imagePicker = UIImagePickerController()
        if UIImagePickerController .isSourceTypeAvailable(UIImagePickerController.SourceType.photoLibrary)
        {
            imagePicker.sourceType = UIImagePickerController.SourceType.photoLibrary
            imagePicker.allowsEditing = true
            imagePicker.delegate = self
            self .present(imagePicker, animated: true , completion: nil)
        }
    }


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

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        if let pickerImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            self.imageView.contentMode = .scaleAspectFit
            self.imageView.image = pickerImage
            dismiss(animated: true)
        }

    }
}

I hope, it will solve your issue.

Probably your answer is here:

ImagePickerManager

It's a copy&paste solution for taking images. I just did a few little changes.

Don't forget to set the right orientation of the picture when taking landscape picture:

Normalize Pictures taken by camera
