iOS 选取用户相册中的图片 UIImagePickerController Swift（ios选取照片）

iOS 选取用户相册中的图片 UIImagePickerController

[GitHub] iOS Demo ： https://github.com/KyleBing/iosDemo
该文中的例子可以从上面这个 github 项目中找到，包含许多其它常用 UI 组件的使用

选取用户相册中图片，或者拍照的方式通过 UIImagePickerController 来实现

内容

从相册中选取一张图片，并按比例显示在当前 ViewController 的中间位置

步骤

VC = ViewController 方便说明，所以简写

1. 在当前 VC 中 实现 UIImagePickerControllerDelegate、UINavigationController 这两个协议
2. 新建一个 picker: UIImagePickerController 和 imageView: UIImageView
3. 设置这个 picker 的 delegate 是 当前 VC
4. 设置 imageView 的内容展示属性：比例缩放
5. 设置选取照片的触发方法，比如在 NavigationBar 中添加一个按钮

6. 实现 UIImagePickerControllerDelegate 的两个方法

   1. 用户选中一张图片时：获取 info 中的信息并进行相关操作，最后使选择窗口消失
   2. 用户取消选择时，使选择窗口消失

效果

cocos2d-x横版项目调用 ios UIImagePickerController

cocos2d-x的一个横版项目需呀用到UIImagePickerController

ios直接报错，原因是不支持横版

最初自己写了ImagePickerViewController专门的ViewController来控制这块，通过addSubview竖屏没问题，但是在横屏有很多的问题

通过paush或者presentModalViewController切换之后，取得图片之后返回游戏，直接报错OpenGL错误

RootViewController添加UIImagePickerController就好了

解决办法
