Question

I have to show one popOver inside the left side of one splitController, I initialize the popOver whit an navigationController. But when i show the popOver my app crash.

Impostazioni *settings = [[Impostazioni alloc] initWithStyle:UITableViewStyleGrouped];
settings.title = NSLocalizedString(@"SETTINGS", nil);
settings.contentSizeForViewInPopover = kContentSizeOfPopOver;
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:settings];
nav.navigationBar.tintColor = kTintColorNavigationBar;
nav.contentSizeForViewInPopover = kContentSizeOfPopOver;
UIPopoverController *popOver = [[UIPopoverController alloc] initWithContentViewController:nav];
[popOver presentPopoverFromBarButtonItem:self.navigationItem.rightBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];

This is my code. Any ideas?

EDIT: Crash even if I set only a viewController instead of SplitController :/ And with a empty ViewController :/

(Possibly duplicate of Error using UIPopoverController.)

In short, you need to retain the UIPopoverController somehow. Either by defining a property for it or by managing the ref count manually. With ARC, the latter is not an option, so you need to store the reference.
