我在 AppStore 上有一个应用程序，我在两天前更新了它。在我检查过的所有手机上，它都运行良好，但我确实收到了一些用户的提示，即应用程序在打开后立即关闭而没有崩溃警报。
我检查了 Xcode 上的崩溃报告，发现了这个错误:\UIKit: __45-[UIView(Hierarchy) _postMovedFromSuperview:]_block_invoke + 556 并看到它与 UI 相关，但我不确定那是应用程序关闭的原因是因为我没有更改版本之间的 UI，而且这也不是崩溃......
我在代码上没有 exit(0)。
很抱歉，没有代码，版本之间的应用打开时没有任何变化(我只是添加了一个 QR 类，用户可以通过单击按钮打开)。
是否有人知道应用关闭(或立即关闭)的可能原因 到后台)没有警报？
编辑:我刚刚有一部手机遇到了这个问题。当我直接从我的计算机安装应用程序时，应用程序可以运行，当我从商店安装时，它会关闭......

如果它没有生成崩溃报告，那么您的应用程序已被系统关闭。这可能有几个原因:分配的内存过多，didStartApplication 太长。尝试在控制台日志中找出您的应用程序被系统关闭的原因。
