自定义UIImagePickerController [英] Customizing a UIImagePickerController

问题描述

我想对UIImagePickerController进行自定义，以允许用户从其相册中选择一张照片。我想知道如果以下是可能的，如果是这样，它是如何实现的：

I'd like to make customizations to a UIImagePickerController that allow the user to select a photo from one of their photo albums. I was wondering if the following is possible and if so, how it's accomplished:

1）更改导航栏的颜色在照片相册视图和视图

1) Change the color of the navigation bar on the "Photo Albums" view and the view that appears after a photo album is selected.

2）编辑两个视图上的按钮及其操作。

2) Edit the buttons and their actions on both of the views.

3）在两个图像选择器视图底部添加工具栏。

3) Add a toolbar to the bottom of both image picker views.

推荐答案

好吧，看来我找到了一个解决方案。如果实现以下导航控制器方法：

Well, it seems I've found a solution. If you implement the following navigation controller method:

   - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated 
{
}

访问控制拾取器的导航控制器，并且还将向出现的每个视图控制器发送指针。所以我相信这两个项目，你可以操纵任何你喜欢。

It will give you access to the navigational controller that controls the picker, and also will send a pointer to each view controller that appears. So I believe with those two items, you can manipulate whatever you please.
