iOS：获取当前设备型号等信息

1、获取设备型号（2017.11.02）

#include <sys/types.h> 
#include <sys/sysctl.h>
//获得设备型号 
+ (NSString *)getCurrentDeviceModel 
{ 
    int mib[2]; 
    size_t len; 
    charchar *machine; 
    mib[0] = CTL_HW; 
    mib[1] = HW_MACHINE; 
    sysctl(mib, 2, NULL, &len, NULL, 0); 
    machine = malloc(len); 
    sysctl(mib, 2, machine, &len, NULL, 0); 
    NSString *deviceString = [NSString stringWithCString:machine encoding:NSASCIIStringEncoding]; 
    free(machine); 

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

苹果用的硬件编码识别，具体可以参考：https://www.theiphonewiki.com/wiki/Models

2、获取设备的信息

• 当前设备
  UIDevice *device = [UIDevice currentDevice];
• 获取设备所有者的名称，例如：@ "小明的 iPhone"
  NSString *name = device.name;
• 获取设备的类别 ,例如：@"iPhone", @"iPod touch"
  NSString *model = device.model;
• 获取本地化版本，基本和model一样
  NSString *type = device.localizedModel;
• 获取当前运行的系统 ,例如：@"iOS"
  NSString *systemName = device.systemName;
• 获取当前系统的版本，例如：@"4.0"
  NSString *systemVersion = device.systemVersion;
