CocoaLumberjack的全局日志级别 [英] Global log level for CocoaLumberjack

问题描述

我在iPhone项目中使用 CocoaLumberjack 来记录一些信息。

I'm using CocoaLumberjack in an iPhone project, to log some information.

我已按照入门指南，一切正常，但有一件事让我感到困惑：似乎没有一种优雅的方式来定义整个应用程序的日志级别。为了使它工作，我需要在每个源文件中定义一个常量，如下所示：

I've followed the Getting started guide, and everything works fine, but there is one thing that bugs me: there doesn't seem to be an elegant way to define a log level for the whole app. To make it work I need to define a constant in every source file, like this:

static const int ddLogLevel = LOG_LEVEL_VERBOSE;

那么，有没有办法为应用程序定义全局日志级别？

So, is there a way to define a global log level for the application?

我找到了这个关于这个主题的文章，但我仍然需要在每个文件中添加一个#import ...

I found this article on the subject, but I still need to add an #import in every file...

推荐答案

我没有找到比我在问题中提到的文章。

Constant.h

extern int const ddLogLevel;

Constant.m

#import "Constants.h"
#import "DDLog.h"

int const ddLogLevel = LOG_LEVEL_VERBOSE;

记录器配置

#import "DDLog.h"
#import "DDASLLogger.h"
#import "DDTTYLogger.h"
#import "DDFileLogger.h"

...

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

 [DDLog addLogger:[DDASLLogger sharedInstance]];
 [DDLog addLogger:[DDTTYLogger sharedInstance]];

 DDFileLogger *fileLogger = [[DDFileLogger alloc] init]; 
 [DDLog addLogger:fileLogger];
 [fileLogger release];

...

导入课程

#import "DDLog.h"
#import "Constants.h"

...

- (void)someMethod {
 DDLogVerbose(@"Log this message");
}
