ios打开照相机与本地相册选择图片
最近正好项目里面要集成“打开照相机与本地相册选择图片”的功能，今天就在这边给大家写一个演示程序；打开相机拍摄后或者在相册中选择一张照片，然后将它显示在界面上。好了废话不多说，因为比较简单直接上源码。
首先，我们在头文件中添加需要用到的actionsheet控件，显示图片的uiimageview控件，并且加上所需要的协议

#import <uikit/uikit.h>
@interface imagepickerviewcontroller : uiviewcontroller<uiimagepickercontrollerdelegate,uiactionsheetdelegate,uinavigationcontrollerdelegate>
@property (strong, nonatomic) iboutlet uiimageview *headimage;
@property (strong, nonatomic) uiactionsheet *actionsheet;
- (ibaction)clickpickimage:(id)sender;
@end

通过点击我设置在界面中的按钮来呼出actionsheet控件，来选择相应的操作拍照或是在相册中选择相片，代码如下：
