在進(jìn)行iOS開發(fā)的過程中，我們有時(shí)需要對(duì)設(shè)備的類型進(jìn)行判別（比如發(fā)微博時(shí)顯示來自哪個(gè)客戶端，就是通過獲取設(shè)備的型號(hào)然后顯示給用戶看）以下就介紹獲取設(shè)備的方法。
我們可以通過代碼直接把方法寫在所需的類中，然后在類中調(diào)用此方法，但寫重復(fù)的代碼對(duì)于程序員來說是很不建議去做的事兒，因?yàn)檫@無疑是在做無用功，我們可以把它寫在一個(gè)類中封裝起來，這樣在別的類中就可以隨時(shí)調(diào)用。
參考：https://www.theiphonewiki.com/wiki/Models，這個(gè)是蘋果官方的設(shè)備類型說明，可以參考一下
【1】首先我們先建一個(gè)New File，命名為GetDeviceModelMethod
【2】在GetDeviceModelMethod.h文件中聲明這個(gè)方法（用于外部調(diào)用），具體代碼如下：
#import
@interfaceGetDeviceModelMethod :UIViewController
+ (NSString*)GetCurrentDeviceModel;
@end
【3】然后我們?cè)僭?GetDeviceModelMethod.m 文件中實(shí)現(xiàn)GetCurrentDeviceModel方法，（記得#include）具體代碼如下：
#import"GetDeviceModelMethod.h"
#include
@interfaceGetDeviceModelMethod()
@end
@implementationGetDeviceModelMethod
//獲得設(shè)備型號(hào)
+ (NSString*)GetCurrentDeviceModel
{
intmib[2];
size_tlen;
char*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*platform = [NSStringstringWithCString:machineencoding:NSASCIIStringEncoding];
free(machine);

returnplatform;
}
@end
【4】這樣我們就可以在別的類里調(diào)用該方法了，具體使用方法如下：
導(dǎo)入頭文件#import"GetDeviceModelMethod.h"
NSString*CurrentDeviceModel=[GetDeviceModelMethodGetCurrentDeviceModel];
NSLog(@"設(shè)備類型=%@",CurrentDeviceModel);//在窗口打印設(shè)備類型
如有不當(dāng)之處，歡迎批評(píng)補(bǔ)充！
