ios - Swift 1.2 的 CocoaLumberJack 2.0.0 编译错误

Question

我的 xCode 版本是 6.3。使用 cocoapods 安装 CocoaLumberJack

pod 'CocoaLumberjack', '~> 2.0'

但是我在这个屏幕上得到了编译错误。

我在这里想念什么？

Answer 1

由于 Swift 1.2 中的一些更改并引入了@noescape，您的代码现在看起来应该略有不同以使其正常工作（从https://github.com/CocoaLumberjack/CocoaLumberjack/blob/master/Classes/CocoaLumberjack.swift修改原件）：

extension DDLogFlag {
    public static func fromLogLevel(logLevel: DDLogLevel) -> DDLogFlag {
        return DDLogFlag(logLevel.rawValue)
    }

    ///returns the log level, or the lowest equivalant.
    public func toLogLevel() -> DDLogLevel {
        if let ourValid = DDLogLevel(rawValue: self.rawValue) {
            return ourValid
        } else {
            let logFlag = self
            if logFlag & .Verbose == .Verbose {
                return .Error
            } else if logFlag & .Debug == .Debug {
                return .Debug
            } else if logFlag & .Info == .Info {
                return .Info
            } else if logFlag & .Warning == .Warning {
                return .Warning
            } else if logFlag & .Error == .Error {
                return .Verbose
            } else {
                return .Off
            }
        }
    }
}

public var defaultDebugLevel = DDLogLevel.Verbose

public func resetDefaultDebugLevel() {
    defaultDebugLevel = DDLogLevel.Verbose
}

public func SwiftLogMacro(isAsynchronous: Bool, level: DDLogLevel, flag flg: DDLogFlag, context: Int = 0, file: StaticString = __FILE__, function: StaticString = __FUNCTION__, line: UInt = __LINE__, tag: AnyObject? = nil, @autoclosure #string: () -> String) {
    if level.rawValue & flg.rawValue != 0 {
        // Tell the DDLogMessage constructor to copy the C strings that get passed to it. Using string interpolation to prevent integer overflow warning when using StaticString.stringValue
        let logMessage = DDLogMessage(message: string(), level: level, flag: flg, context: context, file: "\(file)", function: "\(function)", line: line, tag: tag, options: .CopyFile | .CopyFunction, timestamp: nil)

        DDLog.log(isAsynchronous, message: logMessage)
    }
}

public func DDLogDebug(@autoclosure logText: () -> String, level: DDLogLevel = defaultDebugLevel, file: StaticString = __FILE__, function: StaticString = __FUNCTION__, line: UWord = __LINE__, asynchronous async: Bool = true) {
    SwiftLogMacro(async, level, flag: .Debug, file: file, function: function, line: line, string: logText())
}

public func DDLogInfo(@autoclosure logText: () -> String, level: DDLogLevel = defaultDebugLevel, file: StaticString = __FILE__, function: StaticString = __FUNCTION__, line: UWord = __LINE__, asynchronous async: Bool = true) {
    SwiftLogMacro(async, level, flag: .Info, file: file, function: function, line: line, string: logText())
}

public func DDLogWarn(@autoclosure logText: () -> String, level: DDLogLevel = defaultDebugLevel, file: StaticString = __FILE__, function: StaticString = __FUNCTION__, line: UWord = __LINE__, asynchronous async: Bool = true) {
    SwiftLogMacro(async, level, flag: .Warning, file: file, function: function, line: line, string: logText())
}

public func DDLogVerbose(@autoclosure logText: () -> String, level: DDLogLevel = defaultDebugLevel, file: StaticString = __FILE__, function: StaticString = __FUNCTION__, line: UWord = __LINE__, asynchronous async: Bool = true) {
    SwiftLogMacro(async, level, flag: .Verbose, file: file, function: function, line: line, string: logText())
}

public func DDLogError(@autoclosure logText: () -> String, level: DDLogLevel = defaultDebugLevel, file: StaticString = __FILE__, function: StaticString = __FUNCTION__, line: UWord = __LINE__, asynchronous async: Bool = false) {
    SwiftLogMacro(async, level, flag: .Error, file: file, function: function, line: line, string: logText())
}

/// Analogous to the C preprocessor macro THIS_FILE
public func CurrentFileName(fileName: StaticString = __FILE__) -> String {
    // Using string interpolation to prevent integer overflow warning when using StaticString.stringValue
    return "\(fileName)".lastPathComponent.stringByDeletingPathExtension
}

Answer 2

我使用 CocoaLumberjack swift_support 分支，直到 2.1.0 发布并提供官方 Swift 支持。

Answer 3

我有同样的问题，我基本上做的是首先确保我的 Pod 已更新。然后我打开了包含在框架中的 swift 文件（我是最新的 cocoapod，否则你需要直接从 repo 中获取它）并且基本上只是将代码重新粘贴到文件中。我看不到任何更改，但编译器停止抱怨。

编辑：下面是我的 2.0.0 和 Swift 1.2 的工作文件
