Question

如何在IOS上获得设备的制造和模型？

我想知道是否有可能确定当前设备是什么类型的iPhone(例如)？我知道这是有可能让模型通过
NSString *deviceType = [[UIDevice currentDevice] model];
它只会返回，无论我有“iPhone”还是“iPod”，但我想知道是否有可能检测/知道我是否有iPhone3GS和iPhone4S(实际上，我真正想做的就是确定我是否有3G，因为我做的是相当图形化的东西).

所以是的，让我知道，谢谢！

我添加了一些故障安全，以支持尚未包括在列表中的未来设备：#import <sys/utsname.h>#import "MyClass.h"@implementation MyClass{     //(your private ivars)}- (NSString*) deviceName{     struct utsname systemInfo;     uname(&systemInfo);
