最近项目中新增一个需求，那就是为了方便定位线上的崩溃问题，加入崩溃日志，并且上传服务器。
首先想要崩溃日志能够一眼明了，那么一些必要标识的字段是必不可少的。
思路：采集到崩溃信息过后，保存到本地，然后上传到服务器，上传成功后，直接删除崩溃信息。
有两种方法实现
方法一：
我利用了AvoidCrash来采集和获取崩溃日志，下面上代码
AvoidCrash简介：
AvoidCrash这个框架利用runtime技术对一些常用并且容易导致崩溃的方法进行处理，可以有效的防止崩溃。
并且打印出具体是哪个方法会导致崩溃，让你快速定位导致崩溃的代码。
你可以获取到原本导致崩溃的主要信息<由于这个框架的存在，并不会崩溃>，进行相应的处理。比如：
你可以将这些崩溃信息发送到自己服务器。
你若集成了第三方崩溃日志收集的SDK,比如你用了腾讯的Bugly,你可以上报自定义异常。
或许你会问就算防止了崩溃，但是所获取到的数据变成nil或者并非是你所需要的数据，这又有什么用？对于防止崩溃，我的理解是，宁愿一个功能不能用，都要让app活着，至少其他功能还能用。
在程序启动的时候加入如下代码，打开AvoidCrash。
[AvoidCrash becomeEffective];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(dealwithCrashMessage:) name:AvoidCrashNotification object:nil];
- (void)dealwithCrashMessage:(NSNotification *)note {
//注意:所有的信息都在userInfo中
//你可以在这里收集相应的崩溃信息进行相应的处理(比如传到自己服务器)
NSLog(@"%@",note.userInfo);
//错误名称
NSString *errorName = [NSString stringWithFormat:@"%@",note.userInfo[@"errorName"]];
//错误地方
NSString *errorPlace = [NSString stringWithFormat:@"%@",note.userInfo[@"errorPlace"]];
//错误原因
NSString *errorReason = [NSString stringWithFormat:@"%@",note.userInfo[@"errorReason"]];
//异常
NSString *exception = [NSString stringWithFormat:@"%@",note.userInfo[@"exception"]];
NSString *sysVersions = [[UIDevice currentDevice] systemVersion]; //获取系统版本 例如：9.2
NSDictionary *infoDic = [[NSBundle mainBundle] infoDictionary];
NSString *appVersion = [infoDic objectForKey:@"CFBundleShortVersionString"]; // 获取App的版本
NSString *appName = [infoDic objectForKey:@"CFBundleDisplayName"]; // 获取App的名称
//手机UUId 类imi序列号
NSString *identifierForVendor = [[UIDevice currentDevice].identifierForVendor UUIDString];
//获取手机的型号
struct utsname systemInfo;
uname(&systemInfo);
NSString *model = [NSString stringWithCString: systemInfo.machine encoding:NSASCIIStringEncoding];
NSString *phoneModel = [self currentModel:model];
//1.手机系统版本：11.0
NSString* phoneVersion = [[UIDevice currentDevice] systemVersion];
NSString *exceptionInfo =
[NSString stringWithFormat:@"sysVersions:%@\n appVersion:%@\n appNamek:%@\n phoneModel:%@\n errorName:%@\n errorPlace:%@\n errorReason:%@\n exception:%@\n",sysVersions,appVersion,appName,phoneModel,errorName,errorPlace,errorReason,exception];
//当前时间
NSString *currentTime = [self getCurrentTimes];
//ime 手机串号后7位
NSString *randomNum = [identifierForVendor substringFromIndex:identifierForVendor.length-6];
//App名称_版本号_日期_时间_7位随机码.txt
[self saveCrashLog:exceptionInfo];
NSString *fileName = [NSString stringWithFormat:@"%@_%@_%@_%@.txt",appName,appVersion,currentTime,randomNum];
NSData *fileData = [self readCrashLog];
[[WSONetClient shareClient] m_UploadCrashLogWithappType:@"21" appVersion:appVersion phoneModel:phoneModel imiNo:identifierForVendor logName:fileName aFile:@"aFile" fileData:fileData phoneVersion:phoneVersion progress:^(NSProgress *uploadProgress) {
} success:^(id response, NSUInteger code, NSString *message) {
//如果上传日志成功 那么删除本地保存的崩溃日志
[self deleteCrashLog];
} failure:^(NSError *error) {
}];
}
//保存崩溃信息到本地
- (void)saveCrashLog:(NSString *)crashLog
{
NSArray *array1 =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *documents = [array1 lastObject];
NSString *documentPath = [documents stringByAppendingPathComponent:@"crashLog.txt"];
// 准备好要存到本地的数组
NSString *log= crashLog;
//将数组存入到指定的本地文件
[log writeToFile:documentPath atomically:YES encoding:NSUTF8StringEncoding error:nil];
}
//删除本地崩溃信息
- (void)deleteCrashLog{
/*
在通过文件的名字获取到文件路径之后，通过NSFileManage来删除某个路径的文件
*/
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *docuPathArr = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documents = [docuPathArr lastObject];
NSString *documentPath = [documents stringByAppendingPathComponent:@"crashLog.txt"];
BOOL blHave = [[NSFileManager defaultManager] fileExistsAtPath:documentPath];
if (blHave) {
BOOL blDele= [fileManager removeItemAtPath:documentPath error:nil];
if (blDele) {
NSLog(@"dele success");
}else {
NSLog(@"dele fail");
}
}
}
//读取崩溃信息
- (NSData *)readCrashLog
{
NSArray *array1 =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *documents = [array1 lastObject];
NSString *documentPath = [documents stringByAppendingPathComponent:@"crashLog.txt"];
NSData *fileData = [NSData dataWithContentsOfFile:documentPath];
return fileData;
}
- (NSString*)getCurrentTimes{
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
// ----------设置你想要的格式,hh与HH的区别:分别表示12小时制,24小时制
[formatter setDateFormat:@"YYYY-MM-dd_HH:mm:ss"];
//现在时间,你可以输出来看下是什么格式
NSDate *datenow = [NSDate date];
//----------将nsdate按formatter格式转成nsstring
NSString *currentTimeString = [formatter stringFromDate:datenow];
NSLog(@"currentTimeString = %@",currentTimeString);
return currentTimeString;
}
//获取当前手机机型。

}
方法二：利用NSSetUncaughtExceptionHandler方法设置全局的异常处理器。
利用NSSetUncaughtExceptionHandler可以用来处理异常崩溃。崩溃报告系统会用NSSetUncaughtExceptionHandler方法设置全局的异常处理器。
在程序加载完成的时候加入
NSSetUncaughtExceptionHandler(&caughtExceptionHandler);
void caughtExceptionHandler(NSException *exception){
/**
* 获取异常崩溃信息
*/
NSArray *callStack = [exception callStackSymbols];//得到当前调用栈信息
NSString *reason = [exception reason];//非常重要，就是崩溃的原因
NSString *name = [exception name];//异常类型
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:xxx@qq.com"];
[mailUrl appendString:@"?subject=程序异常崩溃信息，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]];
}
