iOS OC应用异常捕获，崩溃退出前返回信息给后台

第三方的了，有友盟，腾讯的bugly

 

查了一下网上类似的代码很多，在借鉴前辈的代码后，组合了一下： 

1、捕获异常信息

2、获得当前日期，版本，系统

3、获得出bug的视图控制器转为字符串

4、将前3条信息，同步上传反馈给后台---应用out了

 

代码如下：

//在 APPDelegate🀄️
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {




 ///////////////捕获异常消息捕获函数
    //注册消息处理函数的处理方法
   NSSetUncaughtExceptionHandler(&UncaughtExceptionHandler);

}

#pragma mark    收集异常，上传
void UncaughtExceptionHandler(NSException *exception) {
//异常信息
    NSArray *callStack = [exception callStackSymbols];
    NSString *reason = [exception reason];
    NSString *name = [exception name];
    
//日期
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"YYYY-MM-dd HH:mm:ss"];
    NSString * dateStr = [formatter stringFromDate:[NSDate date]];
//获取崩溃界面
    UIViewController * viewNow = [self topViewControllerWithRootViewController:[UIApplication sharedApplication].keyWindow.rootViewController];
//class 转字符串
    NSString * nowview = NSStringFromClass([viewNow class]);

    
// 用户信息
    NSDictionary * diceuserport= [[NSUserDefaults standardUserDefaults]objectForKey:@"useruidport" ];
//app版本
    NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];
    NSString *appCurVersion = [infoDictionary objectForKey:@"CFBundleShortVersionString"];
//iOS系统
    NSString * devicetext = [NSString stringWithFormat:@"%f",[[[UIDevice currentDevice] systemVersion] floatValue]];

//综合信息
    NSString *content = [NSString stringWithFormat:@"\n日期：%@  \nuid:%@  \n端口：%@  \nAPP版本：%@  \n系统版本：%@   \n错误：%@  \n视图控制器：%@  \n错误原因：%@  \n崩溃所在：%@ ",dateStr,diceuserport[@"uid"],diceuserport[@"port"],appCurVersion,devicetext,name,nowview,reason,[callStack componentsJoinedByString:@"\n"]];
    
    
//同步方法上传服务器 （试了试异步了，还没上传就崩了）
    // 创建URL对象
    NSURL *url =[NSURL URLWithString:YJFKPresentUrlStr];
    NSMutableURLRequest *resuest =[NSMutableURLRequest requestWithURL:url];
    [resuest setHTTPMethod:@"post"];
    [resuest setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [resuest setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:@{@"uid":diceuserport[@"uid"],@"type":@"应用崩溃",@"content":content,@"contact_way":@"App-反馈"} options:NSJSONWritingPrettyPrinted error:nil];
    NSMutableData *tempJsonData = [NSMutableData dataWithData:jsonData];
    resuest.HTTPBody = tempJsonData;
    //4 创建响应对象
    NSURLResponse *response = nil;
    //5 创建连接对象
    NSError *error;
    NSData *data = [NSURLConnection sendSynchronousRequest:resuest returningResponse:&response error:&error];
    NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
//反馈结果
    NSLog(@"%@",dict);
}
