使用ImagePickerController拍摄视频/照片，并在不同的视图上使用它们

Question

有人可以指导我如何在另一个视图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调用它。我想拍照或录像，然后使用它。我想在另一个视图中执行此操作，我可以拥有不同的自定义按钮，这些按钮允许我将其共享到 Facebook，您有什么以及回到我的主要视图。我将如何做到这一点？

这是我到目前为止的代码。

在imagePickerController: didFinishPickingMediaWithInfo:中使用此代码

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

使用密钥UIImagePickerControllerMediaURL获取视频网址，以防捕获视频
