有没有办法在Swift中获得设备型号名称(iPhone 4S, iPhone 5, iPhone 5S等)?

我知道有一个名为UIDevice.currentDevice()的属性。模型,但它只返回设备类型(iPod touch, iPhone, iPad, iPhone模拟器等)。

我也知道在Objective-C中使用以下方法可以轻松完成:

#import <sys/utsname.h>

struct utsname systemInfo;
uname(&systemInfo);

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

但是我正在Swift中开发我的iPhone应用程序,所以有人可以帮助我用等效的方法在Swift中解决这个问题吗?

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”。

我已经实现了一个超轻量级的库,可以根据给出的一些答案来检测使用的设备:https://github.com/schickling/Device.swift

它可以通过迦太基安装,并像这样使用:

import Device

let deviceType = UIDevice.currentDevice().deviceType

switch deviceType {
case .IPhone6: print("Do stuff for iPhone6")
case .IPadMini: print("Do stuff for iPad mini")
default: print("Check other available cases of DeviceType")
}

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

在swift中处理c结构体是很痛苦的。尤其是当里面有c数组的时候。以下是我的解决方案:继续使用objective-c。只需创建一个包装器objective-c类来完成这项工作,然后在swift中使用该类。下面是一个示例类,它就是这样做的:

@interface DeviceInfo : NSObject

+ (NSString *)model;

@end

#import "DeviceInfo.h"
#import <sys/utsname.h>

@implementation DeviceInfo

+ (NSString *)model
{
    struct utsname systemInfo;
    uname(&systemInfo);

    return [NSString stringWithCString: systemInfo.machine encoding: NSUTF8StringEncoding];
}

@end

在迅捷的一面:

let deviceModel = DeviceInfo.model()

对于swift4.0及以上使用以下代码:

let udid = UIDevice.current.identifierForVendor?.uuidString
let name = UIDevice.current.name
let version = UIDevice.current.systemVersion
let modelName = UIDevice.current.model
let osName = UIDevice.current.systemName
let localized = UIDevice.current.localizedModel

print(udid ?? "")
print(name)
print(version)
print(modelName)
print(osName)
print(localized)

基于这个答案和这个答案。我创造了一个公共主旨

如何使用它

let boolean: Bool = UIDevice.isDevice(ofType: .iPhoneX)
// true or false

let specificDevice: DeviceModel.Model = UIDevice.modelType
// iPhone6s, iPhoneX, iPad etc...

let model: DeviceModel = UIDevice.model
// .simulator(let specificDevice), .real(let specificDevice),
// .unrecognizedSimulator(let string), .unrecognized(let string)

let modelName: String = UIDevice.model.name
// iPhone 6, iPhone X, etc...

这是要点里面的代码

public extension UIDevice {
    public static var modelCode: String {
        if let simulatorModelIdentifier = ProcessInfo().environment["SIMULATOR_MODEL_IDENTIFIER"] { return simulatorModelIdentifier }
        var systemInfo = utsname()
        uname(&systemInfo)
        return withUnsafeMutablePointer(to: &systemInfo.machine) {
