任何可能出错的线索都将非常感激。
这里第216行
MenuViewController * menuVC = [[MenuViewController alloc] initWithNibName：nil bundle：nil];
NavControllerPortrait * navController = [[NavControllerPortrait alloc] initWithRootViewController：menuVC];
主要使用iPhone 5和iPad 3rd gen（不确定仅限于这些设备）。
更多信息
另一种频繁发生的崩溃具有类似的堆栈跟踪并且由此代码导致：
CELoginViewController * loginVC = [[CELoginViewController alloc] initWithNibName：nil bundle：nil];
NavControllerPortrait * nav = [[NavControllerPortrait alloc] initWithRootViewController：loginVC];
所以我强烈怀疑或我的自定义UINavigationController或Apple对它的更改。鉴于我不是唯一经历过此次崩溃的人 - 我更倾向于责怪Apple： - ）
谢谢。
我没有足够的声誉来评论和询问细节，但我遇到了同样的问题，主要是在iPhone 5上，还有5c，4s，iPad 3和iPod 5G，我相信即使它没有回答这个问题，我要说的也会有所帮助。
首先，这就是崩溃当您尝试使用OpenGL绘制内容或调整大小或在后台移动MKMapView 时会发生。在崩溃日志中可能并不明显，但我收到的每一个崩溃报告都是在后台启动应用程序的时候。考虑到UIViewController被称为InitialSlidingViewController，它似乎对你来说是一样的。在我的情况下大部分时间都是重要位置更新，但在您的情况下可能是后台获取或访问更新或无声远程通知。
我在我的应用程序中注意到的一件事是它在崩溃时设置导航栏，更具体地说是尝试渲染图像，我在导航栏中设置了着色图像。对于你来说这是另外一些需要OpenGL的东西，可能是像视差一样的动作效果，我在堆栈跟踪中看到_UIAccessibilityReduceMotion？
无论你是什么，或者我是事实上，它在某些设备上发生的事情更多，从不在某些设备上发生意味着它很可能是一个iOS错误。我在堆栈跟踪中也看到CI :: can_use_gpu（），因为它在检查是否可以使用gpu时使用gpu而崩溃。
那么我们如何防止它崩溃了？
你可以尝试禁用你正在使用的功能，对我来说，我会用正确颜色的图像替换图像，而不是使用淡色。
或者您可以尝试加载另一个视图控制器，可能只是一个空视图控制器，当应用程序在后台启动时，然后当它来到前台时，将视图控制器与您正在使用的视图控制器交换。 / p>
I'm getting a lot of crash reports on iOS 8 with this stack trace:

Any clues to what can be wrong will be much appreciated. Here the line 216
MenuViewController *menuVC = [[MenuViewController alloc] initWithNibName:nil bundle:nil];
NavControllerPortrait *navController = [[NavControllerPortrait alloc] initWithRootViewController:menuVC];
Getting it mostly on iPhone 5 and iPad 3rd gen (not sure its limited to those devices).
More info Another crash that happens bit less frequently has similar stack trace and cause by this code:
CELoginViewController *loginVC = [[CELoginViewController alloc] initWithNibName:nil bundle:nil];
NavControllerPortrait *nav = [[NavControllerPortrait alloc] initWithRootViewController:loginVC];
So i strongly suspect or my custom UINavigationController or Apple's changes to it. Given that I'm not the only one experiencing this crash - i tend more to blame Apple :-)
Thanks.
I don't have enough reputation to comment and ask for details, however I am experiencing the same issue, mostly on iPhone 5 but also 5c, 4s, iPad 3 and iPod 5G, and I believe that what I'm going to say will be helpful even if it doesn't answer the question.
First of all, this is the crash that happens when you try to draw something with OpenGL or resize or move a MKMapView in the background. It might not be obvious in your crash logs, but every single one of the crash reports I got was when the application started in the background. It seems like it's the same for you, considering the UIViewController is called InitialSlidingViewController. It was with "Significant Location Update" most of the time in my case, however it could be "Background Fetch" or "Visits" update or "Silent Remote Notification" in your case.
One thing I noticed in my app was that it was setting up the navigation bar when it crashed, more specifically trying to render an image, I have tinted images in my navigation bar. For you it's something else but something that requires OpenGL, maybe a motion effect like parallax, I see _UIAccessibilityReduceMotion in the stack trace?
Regardless of what you are, or I am, doing, the fact that it happens more on some devices and never on some devices means that it's most probably an iOS bug. I also see "CI::can_use_gpu()" in my stack trace, it crashes because it uses gpu while checking if it can use gpu.
So how do we prevent it from crashing?
You can try disabling the feature you are using, for me I'll replace the image with the correctly colored one, instead of using a tint color.
Or you can try loading another view controller, maybe just an empty view controller, when the app starts in the background, then when it comes foreground swap the view controller with the one you are using right now.
