推荐答案

嗯，这是一个提示。显然，通知消息已从iOS 7.1更改为iOS8.1

Well, here's a hint. Apparently the notification message has changed from iOS 7.1 to iOS8.1

我的应用程序也遇到了相同的行为/崩溃，并捕获了每个操作系统的崩溃日志：

I got the same behavior/crash on my app as well and captured crash logs for each OS:

7.1说：

虽然iOS 8.1说：

Application Specific Information:
com.company.app failed to scene-update in time

所以，几乎所有内容都是相同的，除了特定于应用程序的信息部分。

So, pretty much everything is the same except for the Application Specific Information section.

在我们的例子中，在主线程上运行的方法没有完成因此它正在获得用户界面的其余部分被卡住，系统正在查杀它。一旦我们修复了两个版本的问题就消失了。

In our case there was a method running on the Main thread that wasn't completing therefore it was getting the rest of the UI stuck and the system was killing it.As soon as we fixed that the problem went away on both versions.

请检查可能导致您的主要问题的原因线程挂起。

So check what might be causing your Main thread to hang.
