Ios UIImagePickerController:didFinishPickingMediaWithInfo未被调用

希望你们都做得很好。不知道是否有人能帮我理解为什么Xcode不能很好地与我相处

为了从UIImagePicker中选择个人资料照片，我将代码分为以下几节：

工作：为ImagePicker和NavigationController分配委托类

工作：实例化UIImagePicker变量

工作：加载ImagePickerViewController并启用以选择图像

失败：添加了附加功能，用于使用UIImagePicker关闭和完成拾取，但从未调用过？我做错了什么

提前谢谢

您的签名有误，但由于这是一个可选方法，因此不会收到警告。应该是：

func imagePickerController(picker: UIImagePickerController,
          didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    // Your code
}

好的，我现在似乎已经开始工作了，谢谢你帮助我确定代码是古老的；）现在运行的是：

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    let image = info[UIImagePickerControllerOriginalImage] as? UIImage
    headerView.profilePhoto.contentMode = .ScaleAspectFit
    headerView.profilePhoto.image = image
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    uploadImage(image!)
}

正如大家所建议的，使用didfinishpickingmediawithinfo方法，在swift 5，iOS 13中提取图像，使用信息字典

func imagePickerController(picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [String : AnyObject]) {
  imageView.image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
}

好的，很酷，但如果是这样，我如何将UIImagePicker图像应用到我的UIImageView？感谢您的快速回复！很高兴你让它工作了。我也会更新我的答案，因为我注意到我的签名也有点错误（在你的签名中它是正确的）。值得注意的是，

UIImagePickerControllerOriginalImage

会像上面说的那样，为你提供原始图像，不包括用户可能做的任何编辑或修改。为此，您可以使用

UIImagePickerControllerEditedImage

。

func imagePickerControllerDidCancel(picker: UIImagePickerController) {
    self.dismissViewControllerAnimated(true, completion: nil)
}

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo image: UIImage, editingInfo: [String : AnyObject]?) {
    headerView.profilePhoto.contentMode = .ScaleAspectFill
    headerView.profilePhoto.image = image
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    uploadImage(image)
}

func imagePickerController(picker: UIImagePickerController,
          didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    // Your code
}

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
    let image = info[UIImagePickerControllerOriginalImage] as? UIImage
    headerView.profilePhoto.contentMode = .ScaleAspectFit
    headerView.profilePhoto.image = image
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    uploadImage(image!)
}

func imagePickerController(picker: UIImagePickerController,
                           didFinishPickingMediaWithInfo info: [String : AnyObject]) {
  imageView.image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
}
