Examples of iOS access to photo albums and photo-saving implementations

Implementation results:
1, click the Access album button, you can access the System album, choose to return in the ImageView display
2, click to take photos, access to the camera, the implementation will be saved in the album, Back in the ImageView display

Note: The camera function requires real-computer debugging, the simulator cannot be implemented
The simulator will have the following effect ~ Popup warning Box

Here is the program: note that the two buttons and Uiimageview in this example are added in storyboard;

ViewController.h

@interface ViewController : UIViewController<UINavigationControllerDelegate,UIImagePickerControllerDelegate>@property (weaknonatomicIBOutletUIImageView *imageShow;@end
