Seems like issue with memory management and maybe with (accessibilityUILayoutContainerViewAccessibility in log). 似乎与内存管理有关，也可能与（日志中的accessibilityUILayoutContainerViewAccessibility）有关。 It can be possible to detect unexpected deallocation of MMMFriendListVC by adding breakpoint to method 通过向方法添加断点，可以检测MMMFriendListVC的意外释放。
- (void)dealloc{}
in MMMFriendListVC. 在MMMFriendListVC中。 If you are using ARC it is still possible to use this method with just single NSLog inside. 如果您使用的是ARC，则仍然可以仅使用一个NSLog来使用此方法。 With ARC, make sure to avoid storing NSObject subclasses in properties of type assign because they won't be nullified after deallocation - making possible calling deallocated variable. 使用ARC，请确保避免将NSObject子类存储在类型为assign属性中，因为在释放之后它们不会被清空-可以调用释放的变量。 Without ARC make sure to set pointer as nil after releasing it. 如果没有ARC，请确保在释放指针后将其设置为nil。
If Voice Over was active at the moment of crash it can explain difference between iOS 7 and iOS 8, because VO is having surprising differences in implementation on different iOS version. 如果Voice Over在崩溃时处于活动状态，则可以解释iOS 7和iOS 8之间的差异，因为VO在不同iOS版本上的实现存在令人惊讶的差异。 Sometimes it can be necessary to store retained pointer to view controller a bit longer than expected (for example in NSDictionary for at least some more seconds) to make sure that object won't get called. 有时可能有必要将保留的指针存储到视图控制器中比预期的时间长一点（例如，在NSDictionary中至少保留几秒钟），以确保不会调用该对象。 Maybe in iOS 7 view controller was stored by system as delegate represented by assigned pointer... It is also possible that iOS 7 is a bit faster with deallocating variable with zero retains, and that also would explain observed difference in behaviour. 也许在iOS 7中，视图控制器是由系统存储为由assigned指针表示的委托...。也有可能是iOS 7的速度更快，在保留零的情况下释放变量，这也可以解释观察到的行为差异。
For this moment I suppose one of this possibilities is cause of crash. 目前，我认为这种可能性之一就是崩溃的原因。
