## 1. 在代码中添加手机崩溃日志代码 ##

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
 NSSetUncaughtExceptionHandler(&UncaughtExceptionHandler);
 [self updateAppErrorInfo];
 return YES;
 }
 
 #pragma mark //如果有异常崩溃信息,提交异常
 - (void)updateAppErrorInfo
 {
 NSDictionary * dictionary = [NUD objectForKey:Sandbox_appErrorInfo];
 DLog(@"dictionary==%@",dictionary);
 //如果有异常崩溃信息,提交异常
 if (dictionary&&NotNilAndNull(dictionary[@"content"]))
 {
 static NSString *AppErrorBaseHostURL = @"http://:8080/appmanage/";//提交到自己的日志平台
 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
 NSString * urlString = [[NSString stringWithFormat:@"%@%@",AppErrorBaseHostURL,@"/app/appErrorInfo/add"]stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];
 NSURL *URL = [NSURL URLWithString:urlString];
 manager.requestSerializer.timeoutInterval = 5.f; //请求时间
 manager.requestSerializer = [AFHTTPRequestSerializer serializer];
 manager.responseSerializer = [AFHTTPResponseSerializer serializer];
 
 [manager POST:URL.absoluteString parameters:dictionary progress:^(NSProgress * _Nonnull downloadProgress) {
 
 } success:^(NSURLSessionDataTask * _Nonnull task, id _Nonnull responseObject) {
 
 
 NSDictionary * dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil];
 DLog(@"dic=========%@",dic);
 
 if ([dic[@"success"] isEqualToString:@"0"]) {
 [NUD removeObjectForKey:Sandbox_appErrorInfo];
 }
 } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
 
 }];
 
 }
 }
 #pragma mark 收集异常，存储到本地，下次用户打开程序时上传给我们

###### dSYM符号表获取 ######

xcode->window->organizer->右键你的应用 show finder->右键.xcarchive 显示包内容->dSYMs->test.app.dYSM

###### atos命令 ######

atos命令来符号化某个特定模块加载地址  
`atos [-arch 架构名] [-o 符号表] [-l 模块地址] [方法地址]`

###### 使用终端计算 ######

###### 1.没有模块地址,需要自己计算。 ######

4   NetworkTaxiDriver                   0x00116f29 NetworkTaxiDriver + 323369

0x00116f29 = 1142569;   //将方法地主转化为十进制
    1142569-323369 = 819200；//减去偏移地址，得到模块地址
    819200 = 0xc8000;  //得到的模块地址在转为十六进制

终端示例：

//打开文件
    cd /Users/thinkjoy/Desktop/出租车/出租车V1.6崩溃分析/NetworkTaxiDriver.app.dSYM 
    //根据模块地址和方法地址计算问题代码位置
    atos -arch armv7 -o /Users/thinkjoy/Desktop/出租车/出租车V1.6崩溃分析/NetworkTaxiDriver.app.dSYM/Contents/Resources/DWARF/NetworkTaxiDriver -l 0xc8000 0x00116f29
    
    //问题代码的位置
    -[RSUserMessageVC messageListAry] (in NetworkTaxiDriver) (RSUserMessageVC.m:54)
    thinkjoytekiMacBook-Pro:NetworkTaxiDriver.app.dSYM thinkjoy$

***注意***：使用`armv7`和`arm64`定位到的代码完全不同。

###### 2.有模块地址，可以直接计算。 ######

test 0x00000001018157dc 0x100064000 + 24844252

`0x00000001018157dc`代码地址，`0x100064000`模块地址；
