CocoaLumberjack iOS - 我们可以更改日志文件名和目录吗? [英] CocoaLumberjack iOS - Can we change the logfile name and directory?
问题描述
我在我的项目中使用CocoaLumberjack。我需要将日志文件的名称更改为我的自定义文件名。
I am using CocoaLumberjack in my project. I need to change the name of the logfile to my custom file name.
NSString * applicationDocumentsDirectory = [[[[NSFileManager defaultManager]
URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject] path];
DDLogFileManagerDefault *documentsFileManager = [[DDLogFileManagerDefault alloc]
initWithLogsDirectory:applicationDocumentsDirectory];
DDFileLogger *fileLogger = [[DDFileLogger alloc]
initWithLogFileManager:documentsFileManager];
// Configure File Logger
[fileLogger setMaximumFileSize:(1024 * 1024)];
[fileLogger setRollingFrequency:(3600.0 * 24.0)];
[[fileLogger logFileManager] setMaximumNumberOfLogFiles:1];
[DDLog addLogger:fileLogger];
通过上面的代码,我已将目录更改为Documents。但是现在我还需要更改日志文件名。我怎样才能做到这一点?有可能吗?
By the above code i have changed the directory to the Documents. But now i need to change the logfile name also. How can i achieve this? Is it possible?
推荐答案
虽然我认为我的回复可能为时已晚,但请在下面找到我的解决方案:
Although I believe that my reply might be too late, please find below my solution:
1)继承DDLogFileManagerDefault并覆盖方法:newLogFileName和isLogFile
1) Inherit DDLogFileManagerDefault and override methods: newLogFileName and isLogFile
#import "DDFileLogger.h"
@interface BaseLogFileManager : DDLogFileManagerDefault
@end
#import "BaseLogFileManager.h"
@implementation BaseLogFileManager
-(NSString *)newLogFileName {
NSString *appName = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleIdentifier"];
NSString *timeStamp = [self getTimestamp];
return [NSString stringWithFormat:@"%@%@.log", appName, timeStamp];
}
-(BOOL)isLogFile:(NSString *)fileName {
return NO;
}
-(NSString *)getTimestamp {
static dispatch_once_t onceToken;
static NSDateFormatter *dateFormatter;
dispatch_once(&onceToken, ^{
dateFormatter = [NSDateFormatter new];
[dateFormatter setDateFormat:@"YYYY.MM.dd-HH.mm.ss"];
});
return [dateFormatter stringFromDate:NSDate.date];
}
@end
2)在AppDelegate中,更改下列行:
2) In AppDelegate, change following line:
DDLogFileManagerDefault *documentsFileManager = [[DDLogFileManagerDefault alloc] initWithLogsDirectory:applicationDocumentsDirectory];
TO:
DDLogFileManagerDefault *documentsFileManager = [[BaseLogFileManager alloc] initWithLogsDirectory:applicationDocumentsDirectory];
