如何在Swift中獲得硬件細節？

Question

如何獲取CPU模型，CPU使用率，CPU空閒，RAM詳細信息，存儲細節等硬件信息？我使用Xcode 7.1.1和Swift 2.我不想製作應用程序。我試過,NSProcessInfo。我看到了幾個帖子，但我沒有找到任何解決辦法。

Answer 1

大部分這些東西都可以通過一些較低級別的C API展現出來。這對你來說可能是一個很好的機會，可以根據它們編寫一些簡單的Swift擴展，但是你可以直接在Swift中編寫C代碼來獲得答案。

我喜歡邀功，但我只是鏈接到一些答案的其他人提供：

• Process info
• SystemKit
• DeviceGuru (in swift!)

Answer 2

繼承人，HAS」擴展，我修改了從UIDevice獲取處理器和速度。可能不是最好的方法（所有的值都是硬編碼的），但它的工作原理！

import Foundation 
import NotificationCenter 

public extension UIDevice

    public func getCPUName() -> String 
    { 
     var processorNames = Array(CPUinfo().keys) 
     return processorNames[0] 
    }

     return processorSpeed[0] 
    }

     #if (arch(i386) || arch(x86_64)) && os(iOS) 
     let identifier = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"]! 
     #else 

     var systemInfo = utsname() 
     uname(&systemInfo) 
     let machineMirror = Mirror(reflecting: systemInfo.machine) 
     let identifier = machineMirror.children.reduce("") { identifier, element in

    switch identifier {

    default:          return ["N/A":"N/A"] 
    } 
} 
} 

您可以使用它像這樣：

print(UIDevice.current.getCPUName()) 
print(UIDevice.current.getCPUSpeed())
