Swift中的CocoaLumberjack动态日志记录
Swift中的CocoaLumberjack动态日志记录
提问于 2015-12-02 16:49:23
我试图在Swift中使用CocoaLumberjack。使用pod 'CocoaLumberjack/Swift‘
在目标C中，我做了以下工作
int ddLogLevel = DDLogLevelOff;
@implementation CLDDLoglevel
+ (int)ddLogLevel
{
return ddLogLevel;
}
+ (void)setLogLevel:(int)logLevel
{
ddLogLevel = logLevel;
}在斯威夫特，我不知道怎么做
我创建了一个实现DDRegisteredDynamicLogging的类
这给了我两种方法
static func ddLogLevel() -> DDLogLevel {
}
static func ddSetLogLevel(level: DDLogLevel) {
}但是，我仍然不清楚如何在哪里以及如何声明DDLogLevel来设置和获取
等价于int ddLogLevel = DDLogLevelOff；
我试过了
static var ddLogLevel: DDLogLevel = defaultDebugLevel回答 3

这并不理想，但我已经将其用于CocoaLumberjack 2.2.0，如下所示：
- 将下列内容添加到您的课堂上： 静态变量ddLogLevel: DDLogLevel = .Off静态函数ddSetLogLevel( level : DDLogLevel) { ddLogLevel =level} 这将确保CocoaLumberjack将您的类标识为为日志记录目的注册的类，并使您能够在运行时更改其日志记录级别。
- 在伐木时，请使用。
DDLogWarn(“危险，威尔罗宾逊”，等级: self.dynamicType.ddLogLevel)
level参数至关重要。没有它，消息将始终被记录下来。
我希望CocoaLumberjack的Swift支持能够成熟并消除这些绊脚石。在那之前，祝你伐木愉快！

对于那些仍在寻找在Swift中动态更改日志记录级别的简单方法的人，只需在任何时候使用dynamicLogLevel即可。例如：
dynamicLogLevel = .infoStack Overflow用户

在这个讨论中还有另一个解决方案。它对我来说是暂时的，我正在试验它。
您必须通过定义UnitDDLoggable来采用
var logPrefix = ""
var logLevel = DDLogLevel.Debug它允许一个人简单地写：
DDLogWarn("Danger, Will Robinson"“迅捷2.3”的代码：
import CocoaLumberjackSwift
/// Base protocol for unit specific logging. Generally you won't implement this protocol directly, you will
/// implement one of the protocols that inherit from it
protocol UnitLoggable {
/// Prefix to append to each log line, should include a trailing space to separate it from the log message
var logPrefix:String { get }
}
/// Implment this protocol to use CocoaLumberjack logging with the level controlable at the file level
protocol UnitDDLoggable : UnitLoggable {
/// Lumberjack log level to use for this code unit, Lumberjack log calls in this unit will use this level
/// not the default log level, to use the shared lumberjack level this property should return defaultDebugLevel
var logLevel:DDLogLevel { get }
}
extension UnitDDLoggable {
final func DDLogDebug(@autoclosure logText: () -> String, context: Int = 0, file: StaticString = #file, function: StaticString = #function, line: UInt = #line, tag: AnyObject? = nil, asynchronous async: Bool = true) {
SwiftLogMacro(async, level: logLevel, flag: .Debug, context: context, file: file, function: function, line: line, tag: tag, string: logPrefix + logText())
}
final func DDLogInfo(@autoclosure logText: () -> String, context: Int = 0, file: StaticString = #file, function: StaticString = #function, line: UInt = #line, tag: AnyObject? = nil, asynchronous async: Bool = true) {
SwiftLogMacro(async, level: logLevel, flag: .Info, context: context, file: file, function: function, line: line, tag: tag, string: logPrefix + logText())
}
final func DDLogWarn(@autoclosure logText: () -> String, context: Int = 0, file: StaticString = #file, function: StaticString = #function, line: UInt = #line, tag: AnyObject? = nil, asynchronous async: Bool = true) {
SwiftLogMacro(async, level: logLevel, flag: .Warning, context: context, file: file, function: function, line: line, tag: tag, string: logPrefix + logText())
}
final func DDLogVerbose(@autoclosure logText: () -> String, context: Int = 0, file: StaticString = #file, function: StaticString = #function, line: UInt = #line, tag: AnyObject? = nil, asynchronous async: Bool = true) {
SwiftLogMacro(async, level: logLevel, flag: .Verbose, context: context, file: file, function: function, line: line, tag: tag, string: logPrefix + logText())
}
final func DDLogError(@autoclosure logText: () -> String,context: Int = 0, file: StaticString = #file, function: StaticString = #function, line: UInt = #line, tag: AnyObject? = nil, asynchronous async: Bool = false) {
SwiftLogMacro(async, level: logLevel, flag: .Error, context: context, file: file, function: function, line: line, tag: tag, string: logPrefix + logText())
}
