Question

有没有人在iOS上使用过升级日志？对于我来说，如果添加了常用属性，它就会在第34行的属性_get_valule_impl.cpp上与EXC_BAD_ACCESS崩溃，如果没有添加，则在第267行使用EXC_BAD_ACCESS attribute_value_set.cpp。

琐碎的伐木工作正常。我正在尝试按照此问题中的描述初始化logger： how to use boost log from multiple files with Gloa 并且还可以从官方文档中学习教程。

我正在使用boost 1.5.8并尝试使用1.5.9

更新我正在尝试运行的代码： Logging.h：

#ifndef logging_hpp
#define logging_hpp

#include "boost/log/expressions.hpp"
#include <boost/log/sources/global_logger_storage.hpp>
#include <boost/log/support/date_time.hpp>
#include <boost/log/trivial.hpp>
#include <boost/log/utility/setup.hpp>

#define INFO  BOOST_LOG_SEV(my_logger::get(), boost::log::trivial::info)
#define WARN  BOOST_LOG_SEV(my_logger::get(), boost::log::trivial::warning)
#define ERROR BOOST_LOG_SEV(my_logger::get(), boost::log::trivial::error)

#define SYS_LOGFILE             "/var/log/example.log"

//Narrow-char thread-safe logger.
typedef boost::log::sources::severity_logger_mt<boost::log::trivial::severity_level> logger_t;

//declares a global logger with a custom initialization
BOOST_LOG_GLOBAL_LOGGER(my_logger, logger_t)

#endif

Logging.cpp：

    #include "Logging.h"

namespace attrs   = boost::log::attributes;
namespace expr    = boost::log::expressions;
namespace logging = boost::log;

//Defines a global logger initialization routine
BOOST_LOG_GLOBAL_LOGGER_INIT(my_logger, logger_t)
{
    logger_t lg;

    logging::add_common_attributes();

    logging::add_console_log(
            std::cout,
            boost::log::keywords::format = (
                    expr::stream << expr::format_date_time<     boost::posix_time::ptime >("TimeStamp", "%Y-%m-%d %H:%M:%S")
                    << " [" << expr::attr<     boost::log::trivial::severity_level >("Severity") << "]: "
                    << expr::smessage
            )
    );

    return lg;
}

AppDelegate.mm （我正在使用日志记录）：

#include "Logging.h"

#import "AppDelegate.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    INFO << "My Log Message";
    // Override point for customization after application launch.
    return YES;
}

- (void)applicationWillResignActive:(UIApplication *)application {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

- (void)applicationWillTerminate:(UIApplication *)application {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
