有没有办法通过编程访问iphone崩溃日志文件。 我试图编写一个崩溃报告function，当您在崩溃后启动应用程序时，它会提供将崩溃报告发送到服务器。 我无法find如何获取应用程序内的崩溃日志。

您可以使用相同的以下逻辑。

aslmsg q, m; int i; const char *key, *val; float how_old = fTime ; q = asl_new(ASL_TYPE_QUERY); asl_set_query(q, ASL_KEY_LEVEL, strLoggerLevel ,ASL_QUERY_OP_LESS_EQUAL); asl_set_query(q, ASL_KEY_FACILITY, [@"YourBundleIdOfAPP" UTF8String] ,ASL_QUERY_OP_EQUAL); asl_set_query(q, ASL_KEY_TIME, [[NSString stringWithFormat:@"%.f", [[NSDate date] timeIntervalSince1970] - how_old] UTF8String], ASL_QUERY_OP_GREATER_EQUAL); int goInside=0; aslresponse r = asl_search(NULL, q); while (NULL != (m = aslresponse_next(r))) { NSString *cValueToWrite; NSMutableDictionary *tmpDict = [NSMutableDictionary dictionary]; for (i = 0; (NULL != (key = asl_key(m, i))); i++) { //get the only required fields if(i==12 || i==10 || i==11 || i==8 || i==9 ||i==3) { NSString *keyString = [NSString stringWithUTF8String:(char *)key]; val = asl_get(m, key); NSString *string = [NSString stringWithUTF8String:val]; [tmpDict setObject:string forKey:keyString]; } } cValueToWrite=[[NSString alloc]initWithFormat:@"\n--------------[Debug]----------------\nDateTime: %@\nApplication: %@\nInfo: %@",[tmpDict valueForKey:@"CFLog Local Time"],[tmpDict valueForKey:@"Sender"],[tmpDict valueForKey:@"Message"]]; } 

strLoggerLevel是保存你想要的logging器types的NSString ，其范围高达7。
