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];

异步库，从iphonewiki给你答案

A crazy little experiment for automation fans like me. I made this algorithm that reads the identification code of the device, physical or simulated, and load the theiphonewiki page to extrapolate the model name based on the identification code (example iPhone11,2 -> iPhone XS). The algorithm interfaces with the WIKI page using the internal Wiki API Sandbox tool that allows you to have a JSON response, however the content is not obtainable in JSON (just the part that was needed, that is the wikitables) so I parsed the HTML content to get to the device name, without using third parts HTML parsing libraries.

优点:总是更新，你不需要添加新的设备

缺点:异步回答使用维基页面从网络

                completion(unrecognized)
            }
        }.resume()
    }
}

用法:

var deviceModel:String = ""
WikiDevice.model { (model) in
     print("Using WikiDevice, running on: \(model)")
     deviceModel = model
}

输出:

Using WikiDevice, running on: iPhone 11 Pro Max

如果您需要测试这个库，您可以从这里下载测试项目

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
}

如果你只是想确定模型并做出相应的东西。

你可以这样用:

let isIphoneX = Device().isOneOf([.iPhoneX, .simulator(.iPhoneX)])

在函数中:

func isItIPhoneX() -> Bool {
    let device = Device()
    let check = device.isOneOf([.iPhoneX, .iPhoneXr , .iPhoneXs , .iPhoneXsMax ,
                                .simulator(.iPhoneX), .simulator(.iPhoneXr) , .simulator(.iPhoneXs) , .simulator(.iPhoneXsMax) ])
    return check
}

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。
