Swift - 이미지 앨범에서 불러오고, 다른 View에 넘기기 예제

//ViewController
import UIKit
 
class ViewController: UIViewController,
UIImagePickerControllerDelegate,UINavigationControllerDelegate{
 
    
    @IBOutlet weak var myimage: UIImageView!
    
    @IBOutlet weak var textfield: UITextField!
    
    var string = ""
    
    @IBAction func selectimageButtonTapped(sender: AnyObject) {
        var pickerController = UIImagePickerController()
        pickerController.delegate = self
        pickerController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
        
        self.presentViewController(pickerController, animated: true, completion: nil)
    }
    
    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
        myimage.image = info[UIImagePickerControllerOriginalImage] as? UIImage
        myimage.backgroundColor = UIColor.clearColor()
        self.dismissViewControllerAnimated(true, completion: nil)
    }
    
    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.
    }
    
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        var destinationView : ViewPhoto = segue.destinationViewController as! ViewPhoto
        destinationView.photo = myimage.image!
        destinationView.string = string
        
    }
    
    
    @IBAction func complateButtonTapped(sender: AnyObject) {
        
            string = textfield.text!
        
    }
}
 
 

처음 ViewController에서 사진 앨범에 대해, selectPickerController를 만들고서 접근을 시작.

delegate를 주고서 해당 소스(이미지)에 대한 타입을 결정

앞서 선언한 selectPickerController에 대한 ImagePicker를 만들고 나서 해당 값에 대한 접근을(선택한 이미지)

return값에 맞게 설정해줌

//ViewPhoto
 
import Foundation
import UIKit
 
 
 
 
class ViewPhoto: UIViewController {
    
    @IBOutlet weak var labels: UILabel!
    var string : String = ""
    
    @IBOutlet weak var imageview: UIImageView!
    var photo : UIImage!
    
    override func viewDidLoad() {
        
        super.viewDidLoad()
        
        self.imageview.image = photo
        self.labels.text = string
    }
}
