当应用程序终止时 PushKit 接收推送时 IOS 11 应用程序崩溃

转载作者：塔克拉玛干更新时间：2023-11-02 10:22:07

当 ios 11 更新发布时，我们的应用程序开始表现怪异。我们正在使用 pushkit 来接收与来电和消息相关的推送通知。当应用程序不在后台(处于终止状态)时，当推送通知到达时，IOS 会启动我们的应用程序并执行 didFinishLaunching 方法，而不是通知到达 didReceiveIncomingPushWithPayload 方法然而，在更新到 IOS 11 之后，我们发现当应用程序终止时，有时我们无法收到通知，当我们检查崩溃日志时，我们看到应用程序正在崩溃，这是 IOS 说 cpu 使用率但它成功执行 didFinishLaunching 方法的原因(我们把日志到方法的末尾并打印出来)

我们不知道是什么导致了这个问题，有没有人知道 IOS 11 中的变化会触发这个问题

您可以在下面找到我们的崩溃日志

最佳答案

我们发现，在 ios11 中，apple 减少了应用程序在后台启动应用程序所需的时间(在我们的例子中是 2.9 秒)，所以当你超过它时，应用程序会自动被 iOS 杀死.所以我们找到了最小化加载时间的解决方案(例如最小化启动画面等)，并删除了不需要在后台运行的代码。我们让我们的应用程序在 1.8 秒内启动，比崩溃问题得到解决

关于当应用程序终止时 PushKit 接收推送时 IOS 11 应用程序崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47156318/
