获取模型名称(营销名称)的最简单方法

小心使用私有API -[UIDevice _deviceinfokey:]，你不会被Apple拒绝。

// works on both simulators and real devices, iOS 8 to iOS 12
NSString *deviceModelName(void) {
    // For Simulator
    NSString *modelName = NSProcessInfo.processInfo.environment[@"SIMULATOR_DEVICE_NAME"];
    if (modelName.length > 0) {
        return modelName;
    }

    // For real devices and simulators, except simulators running on iOS 8.x
    UIDevice *device = [UIDevice currentDevice];
    NSString *selName = [NSString stringWithFormat:@"_%@ForKey:", @"deviceInfo"];
    SEL selector = NSSelectorFromString(selName);
    if ([device respondsToSelector:selector]) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Warc-performSelector-leaks"
        modelName = [device performSelector:selector withObject:@"marketing-name"];
#pragma clang diagnostic pop
    }
    return modelName;
}

我是怎么得到"marketing-name"这个密钥的?

运行在模拟器上的NSProcessInfo.processInfo.environment包含一个名为“SIMULATOR_CAPABILITIES”的键，其值是一个plist文件。然后你打开plist文件，你会得到模型名称的关键字“marketing-name”。

struct utsname systemInfo;
uname(&systemInfo);

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

我的简单解决方案是按设备分组，支持新设备iPhone 8和iPhone X在Swift 3:

public extension UIDevice {
    var modelName: 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)))
        }

        switch identifier {
        case "iPhone3,1", "iPhone3,2", "iPhone3,3", "iPhone4,1":
            return "iPhone 4"

        case "iPhone5,1", "iPhone5,2", "iPhone5,3", "iPhone5,4", "iPhone6,1", "iPhone6,2", "iPhone8,4":
            return "iPhone 5"

        case "iPhone7,2", "iPhone8,1", "iPhone9,1", "iPhone9,3", "iPhone10,1", "iPhone10,4":
            return "iPhone 6,7,8"

        case "iPhone7,1", "iPhone8,2", "iPhone9,2", "iPhone9,4", "iPhone10,2", "iPhone10,5":
            return "iPhone Plus"

        case "iPhone10,3", "iPhone10,6":
            return "iPhone X"

        case "i386", "x86_64":
            return "Simulator"
        default:
            return identifier
        }
    }
}

和使用:

switch UIDevice.current.modelName {
  case "iPhone 4":
  case "iPhone 5":
  case "iPhone 6,7,8":
  case "iPhone Plus":
  case "iPhone X":
  case "Simulator":
  default:
}

下面是获取硬件字符串的代码，但是您需要比较这些硬件字符串才能知道它是哪个设备。我已经创建了一个类，包含几乎所有的设备字符串(我们保持字符串最新的新设备)。使用方便，请检查

Objective-C: GitHub/DeviceUtil

public func hardwareString() -> String {
  var name: [Int32] = [CTL_HW, HW_MACHINE]
  var size: Int = 2
  sysctl(&name, 2, nil, &size, &name, 0)
  var hw_machine = [CChar](count: Int(size), repeatedValue: 0)
  sysctl(&name, 2, &hw_machine, &size, &name, 0)

  let hardware: String = String.fromCString(hw_machine)!
  return hardware
}

使用Swift 3 (Xcode 8.3)

    func deviceName() -> String {
        var systemInfo = utsname()
        uname(&systemInfo)
        let str = withUnsafePointer(to: &systemInfo.machine.0) { ptr in
            return String(cString: ptr)
        }
        return str
    }

注意:根据官方开发论坛的回答，以这种方式使用元组是安全的。大Int8元组的内存对齐方式将与大Int8数组相同。即:连续且无填充。

我最近在开发这个swift包:

https://github.com/EmilioOjeda/Device

我认为它的主要优点是代码生成的。所以每当一个新的Xcode版本发布时，我所要做的就是运行一个脚本并更新swift包。

代码生成是如何工作的?

它从Xcode的数据库(每个平台)读取并解析设备的数据，以识别正在运行的设备，并为其提供信息。

这是用法……

import Device
// or => 'import iPhoneOSDevice' <= iPhoneOS-only device data
// or => 'import tvOSDevice' <= tvOS-only device data

// A representation of the running device - it could be either actual or simulated.
let device = Device.current

// It is 'true' when running on a physical device.
_ = device.isDevice

// It is 'true' when running on a simulator instance.
_ = device.isSimulator

// It is 'true' when the device does not match either simulators or physical devices.
_ = device.isUnknown

// The identifier for the device.
// i.e.: 'iPhone15,3'
let id = device.id

// The known/commercial name of the device.
// i.e.: 'iPhone 14 Pro Max'
let model = device.model
