iOS获取手机型号，Swift获取手机型号（类似iphone 7这种，检测机型具体型号）

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 != 0 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
