Re: crashing on -[UIViewController presentViewController:animated:completion:] on ios 8
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?

Re: crashing on -[UIViewController presentViewController:animated:completion:] on ios 8
Hi David,
Yes, it was related to the PPRevealSideViewController, which I'll look
into to see if I can fix it.
However, I don't know if that's the problem with my original problem.
That warning for detached view controller has been there for awhile
through iOS 6 - 7 and it has been fine for us and once it gets to iOS
8, we start seeing crash logs that I post before.
Here it is again:

My leading theory at the moment is that I am not setting

controller and somehow iOS 8 does not like it.
Any help is appreciated.

iOS 8 has gotten quite a bit more picky about these things, so things that were
just warnings before may be hard crashes now. Also given how early you are

I'll try to get rid of the warning and see if it still crash in the

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. 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.
