ios bug 分析
ios中线上或者内部测试bug统计收集有两种方法:
1)使用第三方bug收集
1.bugHD
来源http://bughd.com/doc/ios-customize
2.bugtags
来源http://help.bugtags.com/hc/kb/article/124400/
http://help.bugtags.com/hc/kb/article/68482/
3.KSCrash
https://github.com/kstenerud/KSCrash
4.友盟
主要不要多种一起使用,使用多个崩溃收集第三方会导致NSSetUncaughtExceptionHandler()函数指针的恶意覆盖,导致有些第三方不能收到崩溃信息
2)自己搭建后台收集bug
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. NSSetUncaughtExceptionHandler(&UncaughtExceptionHandler); return YES; } void UncaughtExceptionHandler(NSException *exception) { /** * 获取异常崩溃信息 */ NSArray *callStack = [exception callStackSymbols]; NSString *reason = [exception reason]; NSString *name = [exception name]; NSString *content = [NSString stringWithFormat:@"========异常错误报告========\nname:%@\nreason:\n%@\ncallStackSymbols:\n%@",name,reason,[callStack componentsJoinedByString:@"\n"]]; /** * 把异常崩溃信息发送至开发者邮件 */ NSMutableString *mailUrl = [NSMutableString string]; [mailUrl appendString:@"mailto:test@qq.com"]; [mailUrl appendString:@"?subject=程序异常崩溃,请配合发送异常报告,谢谢合作!"]; [mailUrl appendFormat:@"&body=%@", content]; // 打开地址 NSString *mailPath = [mailUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailPath]]; }
NSSetUncaughtExceptionHandler只能监听NSException类型的异常,而引起崩溃的大多数原因如:内存访问错误,重复释放等错误就无能为力了。因为这种错误它抛出的是Signal,
所以必须要专门做Signal处理, 可以参考如下封装;测试时,可以调用abort()函数,模拟发送SIGABRT信号,不要联机测试,要脱机测试。

从iOS设备导出的bug日志大概是这样的:

1.查看 xx.app 文件的 UUID,terminal 中输入命令 :
dwarfdump --uuid xx.app/xx (xx代表你的项目名)
2.查看 xx.app.dSYM 文件的 UUID ,在 terminal 中输入命令:
dwarfdump --uuid xx.app.dSYM
3.crash 文件内第一行 Incident Identifier 就是该 crash 文件的 UUID。
.crash文件的分析
export DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer
b.输出bug信息
