swift - 使用 ImagePickerController 拍摄视频/照片并在不同 View 上使用它们

Question

有人可以指导我如何在另一个 View 中使用刚刚从图像选择器拍摄的照片或视频的正确方向吗？

假设我在按下相机按钮时从主视图中调用它。我想拍摄照片或视频然后使用它。我想在另一个 View 中执行此操作，我可以在其中使用不同的自定义按钮，以便将其分享到 Facebook、您有什么以及返回我的主视图。我该如何去做呢？

这是我到目前为止的代码。

在imagePickerController中使用此代码:didFinishPickingMediaWithInfo:

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    var photo = info[UIImagePickerControllerOriginalImage] as? UIImage
}

捕获视频时使用UIImagePickerControllerMediaURL键获取视频URL
