从App Store收到崩溃日志时，我遇到了麻烦。崩溃日志显示EXC_CORPSE_NOTIFY崩溃。
符号化崩溃日志文件后，我不知道如何进一步进行故障排除。我一直在尝试在自己的设备上进行测试，但没有遇到任何崩溃（均为IOS 12）。
以下是我的崩溃日志：-

您可能想阅读本Tech Note
崩溃日志中的堆栈跟踪可以为您提供有关应用程序在发生之前正在做什么的线索。
就您而言：
Last Exception Backtrace:
0 CoreFoundation 0x2009c7ef8 __exceptionPreprocess + 228
1 libobjc.A.dylib 0x1ffb95a40 objc_exception_throw + 55
2 CoreFoundation 0x2008dfdcc -[NSException raise] + 11
3 Foundation 0x2013d3e54 -[NSObject+ 622164 (NSKeyValueCoding) valueForUndefinedKey:] + 247
4 Foundation 0x201347650 -[NSObject+ 46672 (NSKeyValueCoding) valueForKey:] + 267
5 Jasiez 0x1004114f8 -[Map_ViewController viewDidLoad] + 87288 (Map_ViewController.m:303)
看起来您在[Map_ViewController viewDidLoad]方法中调用了未知属性。 As Apple Documentation states
由valueForKey调用：未找到与a对应的属性时 给定密钥。
那些使我想到了Outlet连接的问题，但是我可以确定没有更多的上下文。
