【iOS】【Swift】写真をその場で撮ったり選択したりする

こんな感じ

import UIKit

class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @IBAction func addButton(sender: AnyObject) {
        self.pickImageFromCamera()
        self.pickImageFromLibrary()
    }


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

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }



    // 写真を撮ってそれを選択
    func pickImageFromCamera() {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) {
            let controller = UIImagePickerController()
            controller.delegate = self
            controller.sourceType = UIImagePickerControllerSourceType.Camera
            self.presentViewController(controller, animated: true, completion: nil)
        }
    }

    // ライブラリから写真を選択する
    func pickImageFromLibrary() {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary) {
            let controller = UIImagePickerController()
            controller.delegate = self
            controller.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
            self.presentViewController(controller, animated: true, completion: nil)
        }
    }


    // 写真を選択した時に呼ばれる
    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
        if info[UIImagePickerControllerOriginalImage] != nil {
            let image = info[UIImagePickerControllerOriginalImage] as UIImage
            println(image)
        }
        picker.dismissViewControllerAnimated(true, completion: nil)
    }
}
