QBImagePickerController is a clone of UIImagePickerController with multiple selection feature.
#import <AssetsLibrary/AssetsLibrary.h>
#import "QBImagePickerController.h"
in your ViewController.
QBImagePickerController is not a subclass of UINavigationController.
If you want to show the picker as a modal view, you have to set the picker to topViewController property of an instance of UINavigationController and use it.
If you want to push the picker to NavigtionController, you don't have to do anything.
QBImagePickerController *imagePickerController = [[[QBImagePickerController alloc] init] autorelease];
imagePickerController.delegate = self;
imagePickerController.filterType = QBImagePickerFilterTypeAllPhotos;
imagePickerController.showsCancelButton = YES;
imagePickerController.fullScreenLayoutEnabled = YES;
imagePickerController.allowsMultipleSelection = YES;
imagePickerController.limitsMaximumNumberOfSelection = YES;
imagePickerController.maximumNumberOfSelection = 6;
UINavigationController *navigationController = [[[UINavigationController alloc] initWithRootViewController:imagePickerController] autorelease];
[self presentViewController:navigationController animated:YES completion:NULL];
