Open Image Gallery and Take photo in Swift

In this blog I have demonstrated how to take a photo from your mobile gallery or with your mobile camera and apply it on an ImageView using swift.

UIImagePickerController

UIImagePickerController is a view controller responsible for allowing the developer to access the user's photo library, camera, saved photos album.

UIImagePickerControllerSourceType have 3 options

• UIImagePickerControllerSourceType.PhotoLibrary
• UIImagePickerControllerSourceType.Camera
• UIImagePickerControllerSourceType.SavedPhotosAlbum

 import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate,UIPopoverControllerDelegate,UINavigationControllerDelegate {
    
 var picker:UIImagePickerController?=UIImagePickerController()
    
    @IBOutlet weak var imageView: UIImageView!
    override func viewDidLoad() {
        super.viewDidLoad()
        picker?.delegate=self
        
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        
    }
    
// Open Gallery button click
    @IBAction func OpenGallery(sender: AnyObject) {
        openGallary()
    }
    
// Take Photo button click
    @IBAction func TakePhoto(sender: AnyObject) {
        openCamera()
    }
    
    
    func openGallary()
    {
        picker!.allowsEditing = false
        picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
        presentViewController(picker!, animated: true, completion: nil)
    }

    
    func openCamera()
    {
      if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)){
            picker!.allowsEditing = false
            picker!.sourceType = UIImagePickerControllerSourceType.Camera
            picker!.cameraCaptureMode = .Photo
            presentViewController(picker!, animated: true, completion: nil)
        }else{
           let alert = UIAlertController(title: "Camera Not Found", message: "This device has no Camera", preferredStyle: .Alert)
             let ok = UIAlertAction(title: "OK", style:.Default, handler: nil)
        alert.addAction(ok)
        presentViewController(alert, animated: true, completion: nil)
        }
    }
    
    
    func imagePickerControllerDidCancel(picker: UIImagePickerController) {
        dismissViewControllerAnimated(true, completion: nil)
    }
    
    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
        var chosenImage = info[UIImagePickerControllerOriginalImage] as! UIImage
        imageView.contentMode = .ScaleAspectFit
        imageView.image = chosenImage
        dismissViewControllerAnimated(true, completion: nil)
    }
}
