swift 脚本

1.需求更改xcode build id

PlistBuddy 为操作plist文件的命令行工具
swift 通过process 执行shell脚本, pipe输入执行结果

2.编写swfit脚本

func shell 为固定写法, 作用为执行shell脚本



import Cocoa


// 执行更改, 此处使用时间戳更改 build id

excute(infoPlist: "/Users/ext.guyuxi1/Desktop/未命名文件夹/Info.plist")

// 打印更改后的值
print(shell(path:"/usr/libexec/PlistBuddy", commands:"-c","Print :CFBundleVersion","/Users/ext.guyuxi1/Desktop/未命名文件夹/Info.plist").results)




@discardableResult
func excute(infoPlist path: String)-> String{
    let format = DateFormatter()
        format.dateFormat = "yyyyMMddHHmmss"
// 设置info 中key 为CFBundleVersion 的值
// 此处使用时间戳
// 此处path 为PlistBuddy(操作info.plist的终端)的路径
// commands 为所需要的传参
    return shell(path:"/usr/libexec/PlistBuddy", commands:"-c","Set :CFBundleVersion \(format.string(from: Date()))",path).results
}


/// 执行 Shell 命令 （会等待执行完成）
/// - Parameters:
///   - command: 命令
///   - path: 路径 默认为 "/bind/bash"，即 shell 脚本
/// - Returns: 运行结果和命令执行标准输出
@discardableResult
func shell (path: String = "/bin/bash", commands: String...) -> (status: Int, results:String) {
        
    let task = Process();
    task.executableURL = URL(fileURLWithPath:path)
    var environment = ProcessInfo.processInfo.environment
    environment["PATH"] = "/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin"
    task.environment = environment
    task.arguments = commands
    let pipe = Pipe()
    task.standardOutput = pipe
    task.launch()
    let data = pipe.fileHandleForReading.readDataToEndOfFile()
    let output: String = String(data: data, encoding: String.Encoding.utf8)!
    task.waitUntilExit()
    pipe.fileHandleForReading.closeFile()
    return (Int(task.terminationStatus),output)
}
