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?

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

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

       print("iPhone 4 or iphone 4s")
    }
    else if deviceType.lowercaseString.rangeOfString("iphone 5") != nil {
        print("iPhone 5 or iphone 5s or iphone 5c")
    }
   else if deviceType.lowercaseString.rangeOfString("iphone 6") != nil {
        print("iPhone 6 Series")
    }

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()

/// Obtain the machine hardware platform from the `uname()` unix command
///
/// Example of return values
///  - `"iPhone8,1"` = iPhone 6s
///  - `"iPad6,7"` = iPad Pro (12.9-inch)
static var unameMachine: String {
    var utsnameInstance = utsname()
    uname(&utsnameInstance)
    let optionalString: String? = withUnsafePointer(to: &utsnameInstance.machine) {
        $0.withMemoryRebound(to: CChar.self, capacity: 1) {
            ptr in String.init(validatingUTF8: ptr)
        }
    }
    return optionalString ?? "N/A"
}

我对简单地调用utsname的看法是:

    func platform() -> String {
    var systemInfo = utsname()
    uname(&systemInfo)
    let size = Int(_SYS_NAMELEN) // is 32, but posix AND its init is 256....

    let s = withUnsafeMutablePointer(to: &systemInfo.machine) {p in

        p.withMemoryRebound(to: CChar.self, capacity: size, {p2 in
            return String(cString: p2)
        })

    }
    return s
}

和其他的一样,但对C/Swift和后面的复杂结构更清晰一些。 ):

返回值如"x86_64"
