How to present modal view in "parentViewController"? - ios

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.

Answer 1

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
}]; }

Answer 2

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.

- (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
}];
}
