接上文,本篇我们借鉴一下 JavaScript 中的 console.log:

//
//  Console.swift
//  Console

import Foundation

class console {

    /*!
    *  @method log:
    *
    *  @discussion JavaScript like print method
    *
    */
    class func log<T>(message: T, file: String = __FILE__, method: String = __FUNCTION__, line: Int = __LINE__) {
        #if DEBUG
            print("* ----------------------\n* File: \((file as NSString).lastPathComponent)\n* Line: \(line)\n* Function: \(method)\n* \(message)\n")
        #else
            // save logs
        #endif
    }
}

与上一篇类似,我们的输出依然会额外添加文件名、方法名、行号等信息。

let abc = "def"
console.log("abc = \(abc)")
console.log("Some log")

看看输出结果:

* ----------------------
* File: ViewController.swift
* Line: 19
* Function: viewDidLoad()
* abc = def

* ----------------------
* File: ViewController.swift
* Line: 20
* Function: viewDidLoad()
* Some log
