I have 12 ImageViews in 1 ViewController. I need help so that each ImageView could pick different photos from Library. Someone told me to use Tags for them but I can't make it work cause i'm new in Swift.

推荐答案

Enable User Interaction Enabled 为 Storyboard 上的每个 UIImageView.

Enable User Interaction Enabled for each UIImageView on a Storyboard.

将 TapGestureRecogniser 添加到每个 UIImageView.将每个 TapGestureRecogniser 与 IBAction 连接起来.

Add TapGestureRecogniser to each UIImageView. Connect each TapGestureRecogniser with IBAction.

@IBAction func tap(_ sender: UITapGestureRecognizer) {

    currentImageView = sender.view as! UIImageView

    let picker = UIImagePickerController()
    picker.delegate = self
    self.present(picker, animated: true, completion: nil)

}

定义变量来存储当前UIImageView

private var currentImageView: UIImageView? = nil

处理图像选择并将图像分配给currentImageView

Handle image selection and assign the image to currentImageView

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {

    let image = info[UIImagePickerController.InfoKey.originalImage]
    currentImageView?.image = image as! UIImage

    self.dismiss(animated: true, completion: nil)
}
