使用Swift中的imagePickerController在同一视图控制器中选择两幅不同的图像
使用Swift中的imagePickerController在同一视图控制器中选择两幅不同的图像
提问于 2015-06-05 02:11:33
我正在制作一个有两个UIImageViews的应用程序。在每个图像视图中，用户需要能够输入不同的图像。这是我到目前为止的代码。
var imagePicker = UIImagePickerController()
@IBAction func chooseImage1(sender: AnyObject) {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum){
println("Button capture")
imagePicker.delegate = self
imagePicker.sourceType = .SavedPhotosAlbum
imagePicker.allowsEditing = false
self.presentViewController(imagePicker, animated: true, completion: nil)
}
}
@IBAction func chooseImage2(sender: AnyObject) {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum){
println("Button capture")
imagePicker2.delegate = self
imagePicker2.sourceType = .SavedPhotosAlbum
imagePicker2.allowsEditing = false
self.presentViewController(imagePicker, animated: true, completion: nil)
}
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage
chooseImage1.image = pickedImage
let pickedImage2 = info[UIImagePickerControllerOriginalImage] as? UIImage
chooseImage2.image = pickedImage2
dismissViewControllerAnimated(true, completion: nil)
}
func imagePickerControllerDidCancel(picker: UIImagePickerController) {
dismissViewControllerAnimated(true, completion: nil)
}这将为每个不同的图像视图选择相同的图像。我希望能够选择两张单独的照片，每个视图一张。谢谢你的帮助。

你只需要一个UIImagePickerController。您可以保留对所选视图的引用，当用户完成对图像的选择时，只需将所选视图转换为UIImageView并设置其图像属性：
更新：Xcode 11.5·SWIFT5.2或更高版本的
import UIKit
class ViewController: UIViewController, UIImagePickerControllerDelegate ,UINavigationControllerDelegate {
@IBOutlet weak var imageView1: UIImageView!
@IBOutlet weak var imageView2: UIImageView!
var imagePicker = UIImagePickerController()
var selectedVew: UIView!
override func viewDidLoad() {
super.viewDidLoad()
imagePicker.delegate = self
imagePicker.sourceType = .savedPhotosAlbum
imagePicker.allowsEditing = false
[imageView1,imageView2].forEach {
$0?.isUserInteractionEnabled = true
$0?.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(chooseImage)))
}
}
@objc func chooseImage(_ gesture: UITapGestureRecognizer) {
if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum) {
selectedVew = gesture.view
present(imagePicker, animated: true)
}
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
(selectedVew as? UIImageView)?.image = info[.originalImage] as? UIImage
dismiss(animated: true)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
dismiss(animated: true)
}
