ios - 如何添加多个 ImageView 并且每个 ImageView 都可以做图像选择器？

Question

enter image description here我正在制作约会应用程序。因此用户需要更新他们的个人资料中的图像。在个人资料部分，有小 3 个 ImageView 。如果他们想将图像添加到每个 ImageView 中，他们应该通过 UIimagepicker 更新每个 ImageView 。但我知道我只能使用 UIImagepikerControllerDelegate 协议(protocol)中的一个函数。

我该怎么做？

下面是我失败的代码

导入UIKit

类RegisterPicture:UIViewController、UIImagePickerControllerDelegate、UINavigationControllerDelegate {

@IBAction func pick1(sender: AnyObject) {

    let picker1 = UIImagePickerController()

    picker1.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum

    picker1.allowsEditing = true

    picker1.delegate = self

    self.presentViewController(picker1, animated: false, completion: nil)
}

@IBAction func pick2(sender: AnyObject) {

    let picker2 = UIImagePickerController()

    picker2.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum

    picker2.allowsEditing = true

    picker2.delegate = self

    self.presentViewController(picker2, animated: false, completion: nil)
}

@IBAction func pick3(sender: AnyObject) {

    let picker = UIImagePickerController()

    picker.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum

    picker.allowsEditing = true

    picker.delegate = self

    self.presentViewController(picker, animated: false, completion: nil)
}

@IBOutlet var picture1: UIImageView!

@IBOutlet var picture2: UIImageView!

@IBOutlet var picture3: UIImageView!

func imagePickerController(picker1: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {

    picker1.dismissViewControllerAnimated(false, completion : nil)


}

func imagePickerController(picker2: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {

    picker2.dismissViewControllerAnimated(false, completion : nil)
    self.picture2.image = info[UIImagePickerControllerOriginalImage] as? UIImage

}

func imagePickerController(picker3: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {

    picker3.dismissViewControllerAnimated(false, completion : nil)
    self.picture3.image = info[UIImagePickerControllerOriginalImage] as? UIImage

}

func imagePickerControllerDidCancel(picker: UIImagePickerController) {

    picker.dismissViewControllerAnimated(false, completion:nil)

}

func imagePickerControllerDidCancel(picker2: UIImagePickerController) {

    picker2.dismissViewControllerAnimated(false, completion:nil)

}

func imagePickerControllerDidCancel(picker3: UIImagePickerController) {

    picker3.dismissViewControllerAnimated(false, completion:nil)

}

不确定我是否理解您的需要，但我建议这些 UIImageView 可以位于 Collection View 中。

通过这样做，图像选择器的唯一委托(delegate)将是保存图像 Collection View 的 View Controller ，您只需使用所选图像更新所选单元格
