向UNUserNotificationCenter添加大量触发器时，Springboard崩溃
保存自己免受几个小时的调试，因为我在寻找神秘应用程序崩溃漏洞后2周就浪费了。事实证明，如果您向UNUserNotificationCenter添加了很多o（请参阅答案以获取更多详细信息）通知请求，它将突然崩溃Springboard。我还没有找到解决方法，因为相同的代码适用于iOS 9及更低版本。您似乎无法像之前一样批量添加通知请求。以下是我每次收到的崩溃（数百名应用用户也是如此）。知道我能做什么而不是回到使用UILocalNotification s？

更新：它似乎不是基于特定数量的通知。我碰巧经常触发它，因为我在应用程序处于后台时注册了大约30到40个通知（推送通知，应用程序刷新，应用程序转到后台等） - 因为异常添加这些警报需要比平时更长的时间，应用程序同时放弃它所持有的后台任务标识符。我已在下面详细解释了这一点，以及解决方法。
此错误已被Apple确认，并标记为先前报告的错误的副本。我希望这会得到解决，因为它会在某些边缘情况下继续导致问题，即应用程序在后台启动并且很快就会超时（在后台内容刷新期间）。

我找到了解决方法（已经使用Apple错误ID 29286162记录错误）
从本质上讲，如果UNUserNotificationCenter忙于添加通知并且它还没有完成，那么SpringBoard似乎崩溃了，而用户按下主页按钮返回SpringBoard。很明显，线程正在以某种方式死亡（好吧，可能因为我必须放弃后台任务标识符，希望UNUserNotificationCenter能够愉快地消耗其自己的系统提供的后台线程中传递的请求），离开处于不稳定状态的正在进行的异步操作，导致Springboard最终崩溃。我现在只是在后台任务（UIBackgroundTaskIdentifier）中生成一个线程并保持它直到它完成添加所有通知。这导致零崩溃 - 所有以前抱怨过的用户都证实了这一点。
// arrTasksToSchedule -> holds UNNotificationRequests to add
__block NSInteger volatile processedAlerts = 0;
NSInteger totalToProcess = [arrTasksToSchedule count];
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
for (UNNotificationRequest* notifRequest in arrTasksToSchedule) {
[center addNotificationRequest:notifRequest withCompletionHandler:^(NSError * _Nullable error) {
processedAlerts++;
}];
}
// Let the runloop carry on processing events till we're done
while (processedAlerts != totalToProcess) {
[[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
}
// Okay we're done, and can now let go of our held UIBackgroundTaskIdentifier
文档没有说明后台任务，在后台任务中使用UNUserNotificationCenter的危险或与多线程等有关的事情。我只能假设他们没有意识到大多数应用程序在进行通知注册时他们的应用程序被发送到后台（或在后台内容刷新推送通知期间）。
由于Springboard崩溃 - 没有为应用程序本身生成崩溃报告。用户一直抱怨，这是你不知道的非常困难的情况之一。我希望这可以让别人头疼。
更新：虽然上面的代码现在运行得很好，但我做了一点修改，因为如果用户关闭应用，可能无法满足while循环的条件和按下电源按钮关闭屏幕。在这种情况下，runloop显然没有任何处理和阻止。相反，以下是诀窍：
// Wait in a run loop
while (processedAlerts != totalToProcess) {
[NSThread sleepForTimeInterval:0.15];
// Don't use the following, as it will stop firing in case
// the runloop has no events (such as touch events) firing
// [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]];
}

最近，Todoist的人发布了一个更新（11.2.7），表明他们已经解决了Springboard崩溃问题。
不久之后，Apple发布了iOS 10.2。从那时起，我开始收到我的应用用户的报告，说明错误已经解决。然而，很奇怪Todoist的人如何处理这个问题，我向他们伸出手，这是他们的主要iOS开发者与我分享的内容：
嗨俊杰，
