iOS应用程序闲置一段时间后崩溃

我的应用程序闲置30分钟后崩溃。下面是崩溃报告..iOS应用程序闲置一段时间后崩溃

该应用程序已加载，但当我尝试打开一个弹出式控件（WYPopoverControl）它不会打开，过了一会儿，当我专注于任何文本框时它会随机崩溃。崩溃之后，当应用程序重新打开时，所有内容都将恢复正常工作。我如何调试这些问题？

崩溃的样子，我不去除通知中心的观察员。我把RemoveObserver在dealloc的操作系统所需的所有地方..但它仍然崩溃

尝试在'viewWillDisappear'中放入'RemoveObserver' – Akhilrajtr

你有没有解决过这个问题？ @Akhilrajtr - 为什么会更好？ Dealloc是适合它的地方。 –

@travoux：你是否已经解决了这个问题？如果是，请分享你的解决方案 – user3608500

你注册了一个通知使用addObserver，但你永远不会删除自己作为该笔记的接收者。使用removeObserver（都与通知中心）。

现在你原来的“听众”消失了，但因为它仍然注册 - BOOM

，所以不要忘记注销自己！

我已经在我订阅通知的所有类中添加了这项功能 - （void）dealloc {[NSNotificationCenter defaultCenter] removeObserver：self]; } – travoux

之前的错误？这绝对是因为UIDeviceOrientationDidChange注意事项 –

也许你使用了错误的选择器;） –

我以前见过类似的破坏者。我有两个建议： 1.在viewWillAppear中添加一个观察者和viewWillDisAppear 2.删除指定的观察员就像一个实例：使用

NSNotificationCenter *center = [NSNotificationCenter defaultCenter]; 
NSOperationQueue *mainQueue = [NSOperationQueue mainQueue]; 
self.localObserver = [center addObserverForName:NSManagedObjectContextObjectsDidChangeNotification 
                object:self.managedObjectContext queue:mainQueue usingBlock:^(NSNotification *notification) { 
                 //do something when you get this notification 
                }];

，然后在viewWillDisAppear注销它：

[[NSNotificationCenter defaultCenter] removeObserver:self.localObserver];

我所看到的是dealloc不在iOS 8中调用，它只在您收到内存警告时调用。所以尽量不要在那里取消注册。在早期版本中，它曾经像那样工作。

注意：在上面的代码片段中，我正在观察NSManagedObjectContextObjectsDidChangeNotification。您可以根据您的要求更改它。

它最好使用-viewDidAppear：和 - viewDidDisappear :,因为对该函数的调用总是匹配的。在iOS 7+中，-viewWillAppear并不意味着视图真的会出现：它只是意味着它开始出现。例如。如果用户在导航视图控制器中做了一个反滑手势，并最终决定不想向后滑动（即他取消了该手势），则将调用-viewWillAppear，但最终该视图仍然不可见。当用户按下后退按钮时，再次调用-viewWillAppear：。 – Michael
