在 Swift 2 和 3 中使用带有 1 个按钮的 imagePickerController 在同一个视图控制器中选取两个不同的图像

Question

我正在尝试选择每个带有 1 个按钮的图像，但它没有显示我选择的任何图像。

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)
}

我希望能够在 imageView 上分别选择两张不同的照片。谢谢你的帮助。

UIImagePickerController 一次只能选择一张图片。要进行多项选择，您应该使用更新良好的 API，例如 this。
