如何在iOS上获得设备制作和模型?

I was wondering if it's possible to determine what kind of iPhone (for example) the currentdevice is? I know it's possible to get the model through NSString *deviceType = [[UIDevice currentDevice] model]; which will just return whether I have an "iPhone" or an "iPod", BUT I was wondering if it's possible to detect/know if I have an iPhone 3GS vs. and iPhone 4 vs. an iPhone 4S (in actuality, all I really want to do is determine if I have a 3G or not, because I'm doing fairly graphics intensive stuff).

所以，请告诉我，谢谢!

如果你有一个plist设备(例如在https://stackoverflow.com/a/17655825/849616中由@Tib维护)来处理Swift 3，你会使用:

extension UIDevice {
    /// Fetches the information about the name of the device.
    ///
    /// - Returns: Should return meaningful device name, if not found will return device system code.
    public static func modelName() -> String {
        let physicalName = deviceSystemCode()
        if let deviceTypes = deviceTypes(), let modelName = deviceTypes[physicalName] as? String {
            return modelName
        }
        return physicalName
    }
}

private extension UIDevice {
    /// Fetches from system the code of the device
    static func deviceSystemCode() -> String {
        var systemInfo = utsname()
        uname(&systemInfo)
        let machineMirror = Mirror(reflecting: systemInfo.machine)
        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8, value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }
        return identifier
    }

    /// Fetches the plist entries from plist maintained in https://stackoverflow.com/a/17655825/849616
    ///
    /// - Returns: A dictionary with pairs of deviceSystemCode <-> meaningfulDeviceName.
    static func deviceTypes() -> NSDictionary? {
        if let fileUrl = Bundle.main.url(forResource: "your plist name", withExtension: "plist"),
            let configurationDictionary = NSDictionary(contentsOf: fileUrl) {
            return configurationDictionary
        }
        return nil
    }
}

稍后您可以使用UIDevice.modelName()调用它。

额外的荣誉归于@Tib(用于plist)， @Aniruddh Joshi(用于deviceSystemCode()函数)。

使用ideviceinfo获取这些值怎么样?应该能够安装它使用brew安装ideviceinfo

然后运行:

PRODUCT_NAME=$(ideviceinfo --udid $DEVICE_UDID --key ProductName)
PRODUCT_TYPE=$(ideviceinfo --udid $DEVICE_UDID --key ProductType)
PRODUCT_VERSION=$(ideviceinfo --udid $DEVICE_UDID --key ProductVersion)

memScoped {

            uname(q.ptr)
            val identifier = NSString.stringWithCString(q.machine, encoding = NSUTF8StringEncoding)

以下是Aniruddh基于uname的方法的现代版本，它不依赖于Mirror，应该适用于Swift 4.2及更高版本:

import UIKit

extension UIDevice {
  var machineName: String {
    var info = utsname()
    return withUnsafeMutablePointer(to: &info) { info in
      // We could alternatively return nil here, or handle
      // errors some other way.
      guard uname(info) == 0 else { return model }
      let offset = MemoryLayout.offset(of: \utsname.machine)!
      let machine = UnsafeRawPointer(info).advanced(by: offset).assumingMemoryBound(to: CChar.self)
      return String(cString: machine)
    }
  }
}

我已经创建了plist文件，以帮助您获得每个设备的完整名称(源代码就在我的答案的末尾)

根据OhhMee的回答，你可以这样使用:

斯威夫特4.0

static func deviceName() -> String {

        var systemInfo = utsname()
        uname(&systemInfo)

        guard let iOSDeviceModelsPath = Bundle.main.path(forResource: "iOSDeviceModelMapping", ofType: "plist") else { return "" }
        guard let iOSDevices = NSDictionary(contentsOfFile: iOSDeviceModelsPath) else { return "" }

        let machineMirror = Mirror(reflecting: systemInfo.machine)
        let identifier = machineMirror.children.reduce("") { identifier, element in
            guard let value = element.value as? Int8, value != 0 else { return identifier }
            return identifier + String(UnicodeScalar(UInt8(value)))
        }

        return iOSDevices.value(forKey: identifier) as! String
    }

不要忘记在桥接头中添加#import <sys/utsname.h>。

Objective - C

#import <sys/utsname.h>

NSString *machineName()
{
    struct utsname systemInfo;
    uname(&systemInfo);

    NSString *iOSDeviceModelsPath = [[NSBundle mainBundle] pathForResource:@"iOSDeviceModelMapping" ofType:@"plist"];
    NSDictionary *iOSDevices = [NSDictionary dictionaryWithContentsOfFile:iOSDeviceModelsPath];

    NSString* deviceModel = [NSString stringWithCString:systemInfo.machine
                                               encoding:NSUTF8StringEncoding];

    return [iOSDevices valueForKey:deviceModel];
}
