如何获取CPU模型,CPU使用率,CPU空闲,RAM详细信息,存储详细信息等硬件信息?我使用Xcode 7.1.1和Swift 2.我想要没有make app。我尝试了UIDeviceNSProcessInfo。我看到了几个帖子,但我找不到任何解决方法。

大部分内容都可以通过一些较低级别的C API来揭示。这可能是您编写基于它们的简单Swift扩展的好机会,但您可以直接在Swift中编写C代码以获得您的答案。

我很乐意接受信任,但我会链接到其他人提供的一些答案:

Heres HAS'我为了从UIDevice获得处理器和速度而修改的扩展。可能不是最好的方式(所有的值都是硬编码的)但是它有效!

import Foundation
import NotificationCenter

public extension UIDevice

你可以像这样使用它:

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

这是来自Apple的更新的CPU信息的列表。即使经过硬编码,它也可以在2021年秋天之前正常工作:)
