获取设备类型/型号 [英] Get Device Type/ Model

问题描述

在此处了解如何检测用户设备： iOS - 如何获取设备制作和型号？

After looking on SO in to how to detect users device here: iOS - How to get device make and model?

我制作了一个快速测试应用程序，根据设备显示警报。我没有收到此代码的提醒。我在这里错过了什么/做错了什么？

I made a quick test app to display an alert depending on device. I get no alert from this code. What am I missing/doing wrong here?

#import "ViewController.h"
#import <sys/utsname.h>

 NSString* machineName()
{
struct utsname systemInfo;
uname(&systemInfo);

return [NSString stringWithCString:systemInfo.machine
                          encoding:NSUTF8StringEncoding];
}



@interface ViewController ()


@end




- (IBAction)btn:(id)sender {

if ([machineName() isEqualToString:@"iPhone5,1"]){


    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"Checking device iphone5" delegate:nil cancelButtonTitle: @"Ok" otherButtonTitles: nil];

    [alert show];




    } else  if ([machineName() isEqualToString:@"iPhone4,1"]){



    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alert" message:@"Checking device iphone4" delegate:nil cancelButtonTitle: @"Ok" otherButtonTitles: nil];

    [alert show];

     }


  }

推荐答案

struct 的机器字段是机器硬件平台，如果程序在iOS模拟器中运行，则x86_64。

The machine field of struct utsname is the machine hardware platform and that is "x86_64" if the program is running in the iOS Simulator.

仅在真实设备上，您将获得字符串如iPhone5,1。

Only on a real device you will get strings like "iPhone5,1".
