获取iphone的系统信息使用[UIDevice currentDevice],信息如下:

[[UIDevice currentDevice] systemName]:系统名称,如iPhone OS

[[UIDevice currentDevice] systemVersion]:系统版本,如4.2.1

[[UIDevice currentDevice] model]:The model of the device,如iPhone或者iPod touch

[[UIDevice currentDevice] uniqueIdentifier]:设备的惟一标识号,deviceID

[[UIDevice currentDevice] name]:设备的名称,如 张三的iPhone

[[UIDevice currentDevice] localizedModel]:The model of the device as a localized string,类似model

详见http://developer.apple.com/library/ios/#documentation/uikit/reference/UIDevice_Class/Reference/UIDevice.html

 

但是以上的信息貌似无法得到设备的硬件信息,例如一个iphone3GS,系统升级到了iphone4。此时使用systemVersion得到的应该是4.x.x,那我们如何知道该设备为iphone3GS呢。网上流传一个方法,经测试应该是有用的。

 

自定义一个类:

#import <Foundation/Foundation.h>

@interface UIDeviceHardware : NSObject {  

}

- (NSString *) platform;

- (NSString *) platformString;

@end

 

 

#import "UIDeviceHardware.h"

#include <sys/types.h>

#include <sys/sysctl.h>

@implementation UIDeviceHardware

- (NSString *) platform{

    size_t size;

    sysctlbyname("hw.machine", NULL, &size, NULL, 0);

    char *machine = malloc(size);

    sysctlbyname("hw.machine", machine, &size, NULL, 0);

    NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];

    free(machine);

    return platform;

}

 

- (NSString *) platformString{

    NSString *platform = [self platform];

    if ([platform isEqualToString:@"iPhone1,1"])    return @"iPhone 1G";

    if ([platform isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";

    if ([platform isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";

    if ([platform isEqualToString:@"iPhone3,1"])    return @"iPhone 4";

    if ([platform isEqualToString:@"iPod1,1"])      return @"iPod Touch 1G";

    if ([platform isEqualToString:@"iPod2,1"])      return @"iPod Touch 2G";

    if ([platform isEqualToString:@"iPod3,1"])      return @"iPod Touch 3G";

    if ([platform isEqualToString:@"iPod4,1"])      return @"iPod Touch 4G";

    if ([platform isEqualToString:@"iPad1,1"])      return @"iPad";

    if ([platform isEqualToString:@"i386"] || [platform isEqualToString:@"x86_64"])         return @"iPhone Simulator";

    return platform;

}

@end

 

使用[[[UIDeviceHardware alloc] init] platform]应该就可以得到设备的硬件版本
