Left/Right drawer content view jumps on initial opening (since iOS 8)

[nickafkhami]

Hey,

first of all thank you for providing this great code as open source. I have an issue that only occurs since iOS 8.

I am using the drawer controller as follows:

MMDrawerController *drawerController = [[MMDrawerController alloc] initWithCenterViewController:[menuViewController.viewControllers objectAtIndex:0] leftDrawerViewController:menuNavigationController];
    drawerController.showsShadow = NO;
    drawerController.openDrawerGestureModeMask = MMOpenDrawerGestureModeAll;
    drawerController.closeDrawerGestureModeMask = MMCloseDrawerGestureModeAll;
    drawerController.maximumLeftDrawerWidth = 268.0;
    [drawerController setDrawerVisualStateBlock:[MMDrawerVisualState parallaxVisualStateBlockWithParallaxFactor:2.0]];
    drawerController.animationVelocity = 1260.0;

"menuNavigationController" is simply a UINavigationController object with a UITableViewController as its root view controller.

Then, in the center view I have another UINavigationController containing a UITableViewController. In this center view, I use the drawer bar button item to toggle the drawer position with this statement:

[self.mm_drawerController toggleDrawerSide:MMDrawerSideLeft animated:YES completion:nil];

When I do this in iOS 8 for the first time after launch the UITableView cells in the left view first start under the navigation bar (so the first cell is not fully visible) and when the toggle animation is completed they drop down to start below the navigation bar without animation. It looks as if the view controller notices after the view did appear that it has a navigation bar and the content view must start below it.

This does not occur in iOS 7 and it does not occur when the drawer is toggled using a gesture instead of a button or when the drawer is toggled with a button after the initial time.

Any help will be much appreciated.

I can confirm this behavior as well. iOS 8 GM, XCode 6.0.1.

[sarn]

I confirm as well. Same behavior.

[kuwait]

same here.

[MikeSherron]

Same behavior.

[rojo69]

Happens here too.

I have the same issue, has anyone figured out how to fix that?

[nealshail]

Seeing it too.. and investigating..

[sebinsua]

I'm seeing this too. Does anybody know what's happening? My first thought was that it was being offset by the height of the status bar (which I remove) but I haven't looked properly yet.

"ostatnicky" posted a solution about turning off the navigation bar´s translucency.
I received a mail notification, but it is strangely enough not visible in the thread.
Anyway, it works for me too...

self.navigationController.navigationBar.translucent = NO;

[ostatnicky]

I removed that because in my project it doesn't work. But I have there ViewDeck, maybe for MMDrawerController it will work. For demo it does.

[nickafkhami]

self.navigationController.navigationBar.translucent = NO;

works for me too. Thanks for posting it guys!

However, this is rather a workaround as you might want a translucent nav bar. So it would be better to find a complete fix in the future.

self.navigationController.navigationBar.translucent = NO;
This solution is works for me too.

[nealshail]

Thanks, This only solves the problem when the navigation bar is set to visible. Try setting
[self.navigationController.navigationBar setHidden:TRUE];
The menu still pops down after the animation completes. Any other ideas?

[sebinsua]

Not sure if others were having exactly the same problem as me. However I can report that I fixed my issue by setting the self.showsStatusBarBackgroundView property to true, and also modifying my custom navigation bar to work differently. My custom navigation bar originally altered its height dependent on the status bar (which can appear or disappear dependent on the child drawers) in order that it always remained the same height with or without the status bar - I ended up requiring a negative status bar height offset if the former property was true.

@sebinsua Okay, thanks for your input. To clarify: I and I think most of the others here just use the default setup with a navigation controller with a content table view controller on the left drawer side without modifying the status bar behaviour, in my case it is always visible. So on the left side I have a status bar, nav bar and table view, very similar to the sample project I think. And the problem is that our table view jumps from below the status bar to below the nav bar after the toggle animation is completed while it should already be there in the first place.
