Question

我将NSLogger集成到我的iOS应用程序中，我发现在集成NSLogger后，我的应用程序变得容易冻结，尤其是在没有互联网时。我在下面添加了代码到main.m，有人知道为什么吗？

Logger *logger = LoggerGetDefaultLogger();
LoggerSetOptions(logger,
                     kLoggerOption_BufferLogsUntilConnection |
                     kLoggerOption_CaptureSystemConsole |
                     kLoggerOption_BrowseBonjour |
                     kLoggerOption_BrowseOnlyLocalDomain);
LoggerSetupBonjour(logger, NULL, NULL));

这是崩溃日志：

Answer 1

首先，您不应该向main.m添加代码。请考虑在您的应用程序委托中放置这样的代码。

其次，0x8badf00d崩溃是由于您的应用程序启动时间过长导致的已知错误。这可能是因为您将日志开始代码放在错误的位置，如上所述。或者它可能是别的东西。

作为一般规则，您在启动应用程序时所拥有的任何内容可能需要一些时间，应该延迟或放在后台线程上。应用程序启动应尽快让用户进入应用程序的主屏幕。
