Global log level for CocoaLumberjack

Question

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

I\'ve followed the Getting started guide, and everything works fine, but there is one thing

Answer 1

Here is a dynamic logging example, which uses DanSkeels DSLogging code from below:

GFDPerson.h

#import 

@interface GFDPerson : NSObject{
@protected
    NSArray         *pLogLevelNames;
    NSArray         *pLogLevelKeys;
    NSDictionary    *pLogLevels;
}

-(void)logPerson;
-(void)setLogLevel:(NSUInteger)logLevel;

@end

GFDPerson.m

#import "GFDPerson.h"
#import "DSLogging.h"

DSLogLevelSetupMutable(DDLogLevelWarning);

@implementation GFDPerson

-(id)init{
    if (self = [super init]) {
        pLogLevelNames = [[NSArray alloc] initWithObjects:
                          @"no logging",
                          @"only errors",
                          @"errors and warnings",
                          @"errors, warnings and infos",
                          @"verbose",
                          nil];

        pLogLevelKeys = [[NSArray alloc] initWithObjects:
                         [[NSNumber numberWithInteger:DDLogLevelOff]stringValue],
                         [[NSNumber     numberWithInteger:DDLogLevelError]stringValue],
                         [[NSNumber     numberWithInteger:DDLogLevelWarning]stringValue],
                         [[NSNumber     numberWithInteger:DDLogLevelInfo]stringValue],
                         [[NSNumber     numberWithInteger:DDLogLevelVerbose]stringValue],
                         nil];

        pLogLevels = [[NSDictionary alloc]initWithObjects:pLogLevelNames
                                                  forKeys:pLogLevelKeys];

        return self;
    }
    return nil;
}

-(void)setLogLevel:(NSUInteger)logLevel{
    ddLogLevel = logLevel;
}

-(void)logPerson{

    NSLog(@"Person is logging with Loglevel: %@",[pLogLevels valueForKey:    [[NSNumber numberWithInteger:ddLogLevel]stringValue]]);
    DDLogVerbose(@"Person log verbose");
    DDLogInfo(@"Person log info");
    DDLogWarn(@"Person log warning");
    DDLogError(@"Person log error");
    DDLogDebug(@"Person log debug");
}

@end

main.m

#import 
#import "DSLogging.h"
#import "GFDPerson.h"

DSLogLevelSetupMutable(DDLogLevelError);

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        // insert code here...
        [DDLog addLogger:[DDASLLogger sharedInstance]];
        [DDLog addLogger:[DDTTYLogger sharedInstance]];

        ddLogLevel = DDLogLevelWarning;
        NSLog(@"Warning:");
        DDLogWarn(@"WARNING LOG!");
        DDLogError(@"ERROR LOG!");
        DDLogVerbose(@"VERBOSE LOG!");

        ddLogLevel = DDLogLevelError;
        NSLog(@"Error:");
        DDLogWarn(@"WARNING LOG!");
        DDLogError(@"ERROR LOG!");
        DDLogVerbose(@"VERBOSE LOG!");

        ddLogLevel = DDLogLevelOff;
        NSLog(@"Off:");
        DDLogWarn(@"WARNING LOG!");
        DDLogError(@"ERROR LOG!");
        DDLogVerbose(@"VERBOSE LOG!");

        ddLogLevel = DDLogLevelVerbose;
        NSLog(@"Verbose:");
        DDLogWarn(@"WARNING LOG!");
        DDLogError(@"ERROR LOG!");
        DDLogVerbose(@"VERBOSE LOG!");

        ddLogLevel = DDLogLevelOff;
        GFDPerson *personA = [[GFDPerson alloc] init];
        [personA logPerson];

        [personA setLogLevel:DDLogLevelVerbose];
        [personA logPerson];

        [personA setLogLevel:DDLogLevelError];
        [personA logPerson];

    }
    return 0;
}

output of this code:

Warning:
WARNING LOG!
ERROR LOG!
Error:
ERROR LOG!
Off:
Verbose:
WARNING LOG!
ERROR LOG!
VERBOSE LOG!
Person is logging with Loglevel: errors and warnings
Person log warning
Person log error
Person is logging with Loglevel: verbose
Person log verbose
Person log info
Person log warning
Person log error
Person log debug
Person is logging with Loglevel: only errors
Person log error
