Question

how to create photo gallery within the app from the 70 pics using throughout in app

ImageView.animationImages = [NSArray arrayWithObjects:    
                             [UIImage imageNamed:@"2a.png"],
                             [UIImage imageNamed:@"2b.png"],
                             [UIImage imageNamed:@"2c.png"],
                             nil];

Do i have to create uiimagepicker like this

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
[self presentModalViewController:imagePicker animated:YES];

If yes then still not clear that how it will collect all the images from throughout the app and show it as a slide show or the user can slide image one by one.

Thanks for help.

If you want to create some photo gallery apps, check out this open source sample.

Created by Michael Waterfall, which includes photo gallery from images stored on server or locally.

If you want to implement like side show, just slide the scrollView programmatically with some delay or using your own animatons.
