Swift 獲取設(shè)備信息（cpu、內(nèi)存蕾哟、運營商狐史，IP）

獲取設(shè)備的一些基本信息私杜，在開發(fā)中還是經(jīng)常用得到，這里做一個筆記救欧，以便日后查用衰粹。

為了方便查看，我把他分成public和private笆怠，public方便外面查看調(diào)用铝耻， private就寫里面具體獲取代碼的實現(xiàn)。直接上代碼：


import UIKit
import CoreTelephony


///public
 class DeviceInfo: NSObject {
    
    ///獲取系統(tǒng)版本
    class func zz_getDeviceSystemVersion() -> String {
        return UIDevice.current.systemVersion
    }
    
    ///獲取系統(tǒng)名稱
    class func zz_getDeviceSystemName() -> String {
        return UIDevice.current.systemName
    }
    
    ///獲取系統(tǒng)名稱 iPhone", "iPod touch"
    class func zz_getDeviceModel() -> String {
        return UIDevice.current.model
    }
    
    ///獲取系統(tǒng)名稱 localized version of model
    class func zz_getDeviceLocalizedModel() -> String {
        return UIDevice.current.localizedModel
    }
    
    ///獲取設(shè)備名稱 如 XXX的iphone
    class func zz_getDeviceUserName() -> String {
        return UIDevice.current.name
    }
    ///獲取總的內(nèi)存
    class func zz_getDeviceDiskTotalSize() -> String {
        return fileSizeToString(fileSize: zz_getTotalDiskSize())
    }
    
    ///獲取可用的內(nèi)存
    class func zz_getDeviceAvalibleDiskSize() -> String {
        return fileSizeToString(fileSize: zz_getAvailableDiskSize())
    }
    
    ///獲取運營商
    class func zz_getDeviceSupplier() -> String {
        return zz_deviceSupplier()
    }
    
    /// 獲取當(dāng)前設(shè)備IP
    class func zz_getDeviceIP() -> String {
      return zz_deviceIP()
    }

    ///獲取cpu核數(shù)類型
    class func zz_getDeviceCpuCount() -> Int {
        return zz_deviceCpuCount()
    }
    
    ///獲取cpu類型
    class func zz_getDeviceCpuType() -> String {
        return zz_deviceCpuType()
    }

    ///獲取設(shè)備名稱
    class func zz_getDeviceName() -> String {
        return zz_deviceName()
    }
}

這里就是具體的實現(xiàn)了：

///private
extension DeviceInfo {
    ///獲取運營商
    private class func zz_deviceSupplier() -> String {
        let info = CTTelephonyNetworkInfo()
        var supplier:String = ""
        if #available(iOS 12.0, *) {
            if let carriers = info.serviceSubscriberCellularProviders {
                if carriers.keys.count == 0 {
                    return "無手機卡"
                } else { //獲取運營商信息
                    for (index, carrier) in carriers.values.enumerated() {
                        guard carrier.carrierName != nil else { return "無手機卡" }
                        //查看運營商信息 通過CTCarrier類
                        if index == 0 {
                            supplier = carrier.carrierName!
                        } else {
                           supplier = supplier + "," + carrier.carrierName!
                        }
                    }
                    return supplier
                }
            } else{
                return "無手機卡"
            }
        } else {
            if let carrier = info.subscriberCellularProvider {
                guard carrier.carrierName != nil else { return "無手機卡" }
                return carrier.carrierName!
            } else{
