本文介绍了苹果系统.如何以编程方式获取CPU温度的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我需要使用Swift获取CPU温度,但是除了.
I need to get CPU temperature using Swift, but I can't find any information except for this.
我认为我应该使用IOKit.framework,但同样也没有太多信息.
I think that I should use IOKit.framework but again there's no much information about it.
推荐答案
using https://github.com/lavoiesl/osx-cpu-temp/blob/master/smc.c 我可以使用它.您必须做一些事情:
using https://github.com/lavoiesl/osx-cpu-temp/blob/master/smc.c I got it to work. You have to do a few things:
将 main()
简化为其他内容:
double calculate()
{
SMCOpen();
double temperature = SMCGetTemperature(SMC_KEY_CPU_TEMP);
SMCClose();
temperature = convertToFahrenheit(temperature);
return temperature;
}
写一个ObjC包装器:
Write an ObjC wrapper:
#import "SMCObjC.h"
#import "smc.h"
@implementation SMCObjC
+(double)calculateTemp {
return calculate();
}
@end
将标题添加到您的 Swift 桥接头.
Add the header to your Swift bridging header.
//
// Use this file to import your target's public headers that you would like to expose to Swift.
//
#import "SMCObjC.h"
如果应用已沙箱化,请为AppleSMC添加安全豁免:
If the app is sandboxed, add a security exemption for AppleSMC:
<dict>
<key>com.apple.security.app-sandbox</key>
<true/>
<key>com.apple.security.files.user-selected.read-only</key>
<true/>
<key>com.apple.security.temporary-exception.sbpl</key>
<array>
<string>(allow iokit-open)</string>
<string>(allow iokit-set-properties (iokit-property "AppleSMC"))</string>
<string>(allow mach-lookup (global-name "com.apple.AssetCacheLocatorService"))</string>
</array>
</dict>
</plist>
从Swift调用它.
import Cocoa
class ViewController: NSViewController {
override func viewDidLoad() {
super.viewDidLoad()
let temp = SMCObjC.calculateTemp()
print("I got \(temp) in swift")
}
}
