How to present modal view in "parentViewController"?

Question

I'm trying to write iPad app.

I have UIViewController as parentViewController (full screen) for masterView and detailView (my handmade splitView). Also I have a separate view (for example moreDetailView) with class and xib, which I would like to show as modal.

masterView has UITableView and detailView has UICollectionView. Both of them has own classes and xib. In detailView there are several items.

In my didSelectItemAtIndexPath: of detailView I would like to show moreDetailView.

So, how can I do that? And how to show it in parentViewController, but NOT in detailView.

Hope my question is understandable.

You are initializing your masterview and detailview in parentview. To access the parentcontroller you can declare a property in detailcontroller as

UIViewController *parent;

and while initializing you can do

detailController.parent=self;

and while showing modal you can do

[parent presentModal]; //instead of [self presentModal];

I hope above works for you, you will need to correct the syntax though.

The code below will present your controller in a modal formsheet (you can change this with the setModalPresentationStyle) on the top of your splitView.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    UIViewController *moreDetailViewController = [[MoreDetailViewController alloc] init];
    [moreDetailViewController setModalPresentationStyle:UIModalPresentationFormSheet]; //or style depending on what you want
    [moreDetailViewController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];

    [self presentViewController:moreDetailViewController animated:YES completion:^{
        //stuff you want to do after the viewController has been presented
    }]; }

is there any method to make dark gradient of back view like in UIAlertView? — Romowski, Apr 10 '13 at 10:28
