	NSString *imageName = [NSString stringWithFormat:@"%ld.JPG", (long)pageIndex + 1];
	return [UIImage imageNamed:imageName];
} numberOfImage:10 direction:RDPagingViewDirectionRight];

You can show a custom view like this.

RDImageViewerController *viewController = [[RDImageViewerController alloc] initWithViewHandler:^UIView *(NSInteger pageIndex, UIView *reusedView) {
	if (reusedView == nil) {
		// create new view
	}
	// customize view
	return reusedView;
} reuseIdentifier:^NSString *(NSInteger pageIndex) {
	return @"view";
} numberOfImages:10 direction:RDPagingViewDirectionRight];

Please check the sample code to know how to use.

To load asynchronous, do this

RDImageViewerController *viewController = ...
viewController.loadAsync = YES;

The property of 'landscapeMode' is meaning zooming style in landscape. If it is setted RDImageViewerControllerLandscapeModeAspectFit
