iOS获取设备型号、设备类型等信息

app开发中  有时候时候需要读取手机的信息  比如说微博  当我们发微博的时候   需要显示发送微博设备的型号,比如说iphone 5s  

这个时候 我们需要一个方法来获取设备的信息   

在oc自带的方法中  有相关的方法  可以获取设备有相关信息  但这些结果往往不是我们想要的  比如说他可以获取设备名:

[UIDevice currentDevice].name   :   “晓牛”的 iPhone

[UIDevice currentDevice].model  :  iPhone

[UIDevice currentDevice].systemName  :  iPhone OS

[UIDevice currentDevice].localizedModel  :  iPhone

[UIDevice currentDevice].identifierForVendor  :  <__NSConcreteUUID 0xc30c6f0> 42CD46F3-D8A1-42D0-9243-F05F8B8CCB5D

[UIDevice currentDevice].systemVersion  :  9.3.1

[UIDevice currentDevice].identifierForVendor  :  <__NSConcreteUUID 0xc30c7a0> 42CD46F3-D8A1-42D0-9243-F05F8B8CCB5D

这时候我们也可以通过一些方法去获得设备的设备版本  从而通过硬编码的方式获取设备型号:

/**
 *  设备版本
 *
 *  @return e.g. iPhone 5S
 */
+ (NSString*)deviceVersion
{
    // 需要#import "sys/utsname.h"
    struct utsname systemInfo;
    uname(&systemInfo);
    NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
    
    //iPhone
    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:@"iPhone5,1"])    return @"iPhone 5";
    if ([deviceString isEqualToString:@"iPhone5,2"])    return @"iPhone 5";
    if ([deviceString isEqualToString:@"iPhone5,3"])    return @"iPhone 5C";
    if ([deviceString isEqualToString:@"iPhone5,4"])    return @"iPhone 5C";
    if ([deviceString isEqualToString:@"iPhone6,1"])    return @"iPhone 5S";
    if ([deviceString isEqualToString:@"iPhone6,2"])    return @"iPhone 5S";
    if ([deviceString isEqualToString:@"iPhone7,1"])    return @"iPhone 6 Plus";
    if ([deviceString isEqualToString:@"iPhone7,2"])    return @"iPhone 6";
    if ([deviceString isEqualToString:@"iPhone8,1"])    return @"iPhone 6s";
    if ([deviceString isEqualToString:@"iPhone8,2"])    return @"iPhone 6s Plus";
    
    //iPod
    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:@"iPod5,1"])      return @"iPod Touch 5G";
    
    //iPad
    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:@"iPad2,4"])      return @"iPad 2 (32nm)";
    if ([deviceString isEqualToString:@"iPad2,5"])      return @"iPad mini (WiFi)";
    if ([deviceString isEqualToString:@"iPad2,6"])      return @"iPad mini (GSM)";
    if ([deviceString isEqualToString:@"iPad2,7"])      return @"iPad mini (CDMA)";
    
    if ([deviceString isEqualToString:@"iPad3,1"])      return @"iPad 3(WiFi)";
    if ([deviceString isEqualToString:@"iPad3,2"])      return @"iPad 3(CDMA)";
    if ([deviceString isEqualToString:@"iPad3,3"])      return @"iPad 3(4G)";
    if ([deviceString isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";
    if ([deviceString isEqualToString:@"iPad3,5"])      return @"iPad 4 (4G)";
    if ([deviceString isEqualToString:@"iPad3,6"])      return @"iPad 4 (CDMA)";
    
    if ([deviceString isEqualToString:@"iPad4,1"])      return @"iPad Air";
    if ([deviceString isEqualToString:@"iPad4,2"])      return @"iPad Air";
    if ([deviceString isEqualToString:@"iPad4,3"])      return @"iPad Air";
    if ([deviceString isEqualToString:@"iPad5,3"])      return @"iPad Air 2";
    if ([deviceString isEqualToString:@"iPad5,4"])      return @"iPad Air 2";
    if ([deviceString isEqualToString:@"i386"])         return @"Simulator";
    if ([deviceString isEqualToString:@"x86_64"])       return @"Simulator";
    
    if ([deviceString isEqualToString:@"iPad4,4"]
        ||[deviceString isEqualToString:@"iPad4,5"]
        ||[deviceString isEqualToString:@"iPad4,6"])      return @"iPad mini 2";
    
    if ([deviceString isEqualToString:@"iPad4,7"]
        ||[deviceString isEqualToString:@"iPad4,8"]
        ||[deviceString isEqualToString:@"iPad4,9"])      return @"iPad mini 3";
    
    return deviceString;
}

有一个比较好用的第三方工具:github  其实它的本质也是上面的方法  只不过进行了封装

直接调用方法就可以获取设备的型号和名称  比较简单

NSLog(@"Device Display Name: %@", [[UIDevice currentDevice] displayName]);

NSLog(@"Device Display Model Name: %@", [[UIDevice currentDevice] displayModelName]);

随着iphone种类越来越多  以上的设备版本 需要及时更新  :  具体最新的版本设备可以通过以下网站查看  从而更新代码:
