crash日志的本地记录

来源：互联网发布：雪梨淘宝店名叫什么编辑：程序博客网时间：2024/06/03 20:37

app大都会crash，而第三方平台截获的崩溃日志，需要文件描述符才能解析。手机上的崩溃日志有时候也定位不到具体行。
我的建议是为了方便，测试版本可以本地记录崩溃日志。线上版本可以使用fir或bugly.
本地记录的好处是实时获取，不需要本地文件描述符。
本地记录崩溃日志的方法是增加如下代码：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    [self configDDLog];    return YES;}- (void)configDDLog {#ifdef DEBUG    //把崩溃日志写入文件    [GBLogWrite redirectNSLogToDocumentFolder];#endif}

打印本地日志的方法是由以前我的同步日志改进过来的。我的同步日志连续快速打印有性能问题，但是应用崩溃前打印一次不在话下，没有任何问题：

注意：我们的同步日志系统在didFinishLaunchingWithOptions之前的崩溃无能为力，毕竟只有同步日志初始化以后才能记录，估计第三方平台也有这样的问题。
