拍照要使用真机测试，iPhone和iPad打开相册方式会有所区别：

for iphone:

[objc] view plaincopyprint?

1. #import "IPhoneViewController.h"  
2.   
3. @interface IPhoneViewController () <UIImagePickerControllerDelegate,UINavigationControllerDelegate>

6. //从相机获取图片  
7. @property (strong, nonatomic)UIImagePickerController *ymImagePickerCamera;  
8. //显示图片  
9. @property (weak, nonatomic) IBOutlet UIImageView *accordingImageView;
