获取手机设备信息，如name、model、version等，

但如果想获取具体的手机型号，如iphone5、5s这种，就需要如下这种（含Swift和OC两种写法）

Swift建议添加到extension，使用简单，直接新建个extension，拷贝下面代码进去即可。

以下是最新的类型：一直到iPhone X

import Foundation

import UIKit

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 !=  else { return identifier }

            return identifier + String(UnicodeScalar(UInt8(value)))

        }

        switch identifier {

        case "iPod1,1":  return "iPod Touch 1"

        case "iPod2,1":  return "iPod Touch 2"

        case "iPod3,1":  return "iPod Touch 3"

        case "iPod4,1":  return "iPod Touch 4"

        case "iPod5,1":  return "iPod Touch 5"

        case "iPod7,1":  return "iPod Touch 6"

        case "iPhone3,1", "iPhone3,2", "iPhone3,3":  return "iPhone 4"

        case "iPhone4,1":  return "iPhone 4s"

        case "iPhone5,1":  return "iPhone 5"

        case "iPhone5,2":  return "iPhone 5"

        case "iPhone5,3", "iPhone5,4":  return "iPhone 5c"

        case "iPhone6,1", "iPhone6,2":  return "iPhone 5s"

        case "iPhone7,2":  return "iPhone 6"

        case "iPhone7,1":  return "iPhone 6 Plus"

        case "iPhone8,1":  return "iPhone 6s"

        case "iPhone8,2":  return "iPhone 6s Plus"

        case "iPhone8,4":  return "iPhone SE"

        case "iPhone9,1", "iPhone9,3":  return "iPhone 7"

        case "iPhone9,2", "iPhone9,4":  return "iPhone 7 Plus"

        case "iPhone10,1", "iPhone10,4": return "iPhone 8"

        case "iPhone10,2", "iPhone10,5": return "iPhone 8 Plus"

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

        case "iPad1,1": return "iPad"

        case "iPad1,2": return "iPad 3G"

        case "iPad2,1", "iPad2,2", "iPad2,3", "iPad2,4":  return "iPad 2"

        case "iPad2,5", "iPad2,6", "iPad2,7":  return "iPad Mini"

        case "iPad3,1", "iPad3,2", "iPad3,3":  return "iPad 3"

        case "iPad3,4", "iPad3,5", "iPad3,6":  return "iPad 4"

        case "iPad4,1", "iPad4,2", "iPad4,3":  return "iPad Air"

        case "iPad4,4", "iPad4,5", "iPad4,6":  return "iPad Mini 2"

        case "iPad4,7", "iPad4,8", "iPad4,9":  return "iPad Mini 3"

        case "iPad5,1", "iPad5,2":  return "iPad Mini 4"

        case "iPad5,3", "iPad5,4":  return "iPad Air 2"

        case "iPad6,3", "iPad6,4":  return "iPad Pro 9.7"

        case "iPad6,7", "iPad6,8":  return "iPad Pro 12.9"

        case "AppleTV2,1":  return "Apple TV 2"

        case "AppleTV3,1","AppleTV3,2":  return "Apple TV 3"

        case "AppleTV5,3":  return "Apple TV 4"

        case "i386", "x86_64":  return "Simulator"

        default:  return identifier

        }

    }

}
使用：

let name = UIDevice.current.modelName

swift：

func phonetype () -> String {

        let name = UnsafeMutablePointer<utsname>.alloc(1)

        uname(name)

        let machine = withUnsafePointer(&name.memory.machine, { (ptr) -> String? in

            let int8Ptr = unsafeBitCast(ptr, UnsafePointer<CChar>.self)

            return String.fromCString(int8Ptr)

        })

        name.dealloc(1)

        if let deviceString = machine {

            switch deviceString {

            //iPhone

            case "iPhone1,1":                return "iPhone 1G"

            case "iPhone1,2":                return "iPhone 3G"

            case "iPhone2,1":                return "iPhone 3GS"

            case "iPhone3,1", "iPhone3,2":   return "iPhone 4"

            case "iPhone4,1":                return "iPhone 4S"

            case "iPhone5,1", "iPhone5,2":   return "iPhone 5"

            case "iPhone5,3", "iPhone5,4":   return "iPhone 5C"

            case "iPhone6,1", "iPhone6,2":   return "iPhone 5S"

            case "iPhone7,1":                return "iPhone 6 Plus"

            case "iPhone7,2":                return "iPhone 6"

            case "iPhone8,1":                return "iPhone 6s"

            case "iPhone8,2":                return "iPhone 6s Plus"

            case "iPhone8,4":                return "iPhone SE"

            case "iPhone9,1":                return "iPhone 7"

            case "iPhone9,2":                return "iPhone 7 Plus"

            case "iPad3,1":                 return "iPad 3"

            case "iPad3,2":                 return "iPad 3"

            case "iPad3,3":                 return "iPad 3"

            case "iPad3,4":                 return "iPad 4"

            case "iPad3,5":                 return "iPad 4"

            case "iPad3,6":                 return "iPad 4"

            case "iPad4,1":                 return "iPad Air"

            case "iPad4,2":                 return "iPad Air"

            case "iPad4,3":                 return "iPad Air"

            default:

                return deviceString

            }

        } else {

            return ""

        }

    }

　　

OC：

+ (NSString*)deviceVersion

{

    // 需要#import "sys/utsname.h"

    struct utsname systemInfo;

    uname(&systemInfo);

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

    //CLog(@"%@",deviceString);

    if ([deviceString isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";

    if ([deviceString isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";

    if ([deviceString isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";

    if ([deviceString isEqualToString:@"iPhone3,1"])    return @"iPhone 4";

    if ([deviceString isEqualToString:@"iPhone3,2"])    return @"Verizon iPhone 4";

    if ([deviceString isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";

    if ([deviceString isEqualToString:@"iPhone5,2"])    return @"iPhone 5";

    if ([deviceString isEqualToString:@"iPhone6,2"])    return @"iPhone 5S";

    if ([deviceString isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";

    if ([deviceString isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";

    if ([deviceString isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";

    if ([deviceString isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";

    if ([deviceString isEqualToString:@"iPad1,1"])      return @"iPad";

    if ([deviceString isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";

    if ([deviceString isEqualToString:@"iPad2,2"])      return @"iPad 2 (GSM)";

    if ([deviceString isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";

    if ([deviceString isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";

    if ([deviceString isEqualToString:@"i386"])         return @"Simulator";

    if ([deviceString isEqualToString:@"x86_64"])       return @"Simulator";

    //CLog(@"NOTE: Unknown device type: %@", deviceString);

    return deviceString;

}

　　

ps：这两个方法由于老早写的，类型有缺失，大家自己补上就好了
