Hi David,
Here is my set up in term of view controllers.
- (void) setUpTabbarController {
self.tabBarController = [[MyTabbarViewController alloc] init];
ViewController *v1 = [[HubActivityViewController alloc]
initWithNibName:nil bundle:nil];
ViewController *v2 = [[CalendarContainerViewController alloc]
initWithNibName:nil bundle:nil];
ViewController *v3 = [[HubTaskGroupsViewController alloc] init];
UINavigationController* nav1 = [[UINavigationController alloc]
initWithRootViewController:v1];
UINavigationController* nav2 = [[UINavigationController alloc]
initWithRootViewController:v2];
UINavigationController* nav3 = [[UINavigationController alloc]
initWithRootViewController:v3];
self.tabBarController.viewControllers = [NSArray
arrayWithObjects:nav1, nav2, nav3, nil];
nav1.delegate = self.tabBarController;
nav2.delegate = self.tabBarController;
nav3.delegate = self.tabBarController;
self.revealSideViewController = [[PPRevealSideViewController alloc]
initWithRootViewController:self.tabBarController];
[self.revealSideViewController
setDirectionsToShowBounce:PPRevealSideDirectionNone];
[self.revealSideViewController
setPanInteractionsWhenClosed:PPRevealSideInteractionContentView |
PPRevealSideInteractionNavigationBar];
[self.revealSideViewController
setOption:PPRevealSideOptionsResizeSideView];
self.window.rootViewController = self.revealSideViewController;
// set the modal presenting style, possible fix for crash on iOS 8
if ([Util isRunningIOSEight]) {
self.window.rootViewController.modalPresentationStyle =
UIModalPresentationOverFullScreen;
}
}
We use a library called "PPRevealSideViewController"
(https://github.com/ipup/PPRevealSideViewController/commits/master) to
provide a slide menu in our app. Whenever we call [self
presentViewController:] from on of the view controller inside the
tabbarcontroller (i.e.: v1), we get the detached view controller
warning.
Do you think the warning is related to the menu library or the way I set
up my tabbarcontroller?

Hi Ben,
I have both in my app, both presenting from rootVC and just plain
controller. I fish out the rootVC to get rid of warning like this
"Presenting view controllers on detached view controllers is
discouraged”.
So why do you have detached view controllers in the first place?
Detached view controllers have been discouraged ever since it was
possible to setup the parent-child relationship in the first place. I
suspect that if you fix your detached view controllers that you will
fix this issue too.
I am seeing crash logs from both instance of presenting view
controllers (both from rootVC and not), so that's probably not the
issue here.

[vc presentViewController:navigationController animated:YES
completion:nil];
Is there a particular reason why you are fishing out the root view
controller via the delegate singleton? Does it work properly if
your LeftMenuViewController instance (the class which according to
your trace is making the call) simply calls presentViewController on
itself instead?
