Difference processing code of iOS for iphone and ipad cameras and image Libraries

The iPhone and iPad have different processing methods for the camera and image library code. The iPad is mainly used

UIPopoverController to include UIImagePickerController.

The main code is as follows:

1. The class is inherited from UIViewController, and then UINavigationControllerDelegate and

UIImagePickerControllerDelegate.

2. Modify the corresponding code in the laungh function of the appDelegate class of ios:

    // Set RootViewController to window    if ( [[UIDevice currentDevice].systemVersion floatValue] < 6.0)    {        // warning: addSubView doesn't work on iOS6         [window setRootViewController:viewController];        [window addSubview: viewController.view];    }    else    {        // use this method on ios6        [window setRootViewController:viewController];    }

The main purpose is to set

[window setRootViewController:viewController];

Prevent crash when window. rootViewController is used later.

3. *. The H file contains the following member variables:

    UIImagePickerController* picker_camera_;    UIImagePickerController* picker_library_;    UIWindow * window;    UIPopoverController  * pc_image_picker_;

4. *. mm file content is as follows:

I will not talk about the specific details, mainly to distinguish between iPhone and iPad, and then to distinguish between SDK6.0 and above and below 6.0.
