在iOS中获取设备ID或Mac地址

Question

我有一个使用rest来与服务器通信的应用程序,我想获取iphone的mac地址或设备ID以进行唯一性验证,如何做到这一点？

Answer 1

[[UIDevice currentDevice] uniqueIdentifier] 保证每个设备都是唯一的.

Answer 2

uniqueIdentifier(在iOS 5.0中不推荐使用.相反,请创建特定于您的应用的唯一标识符.)

文档建议使用CFUUIDCreate而不是[[UIDevice currentDevice] uniqueIdentifier]

以下是您在应用中生成唯一ID的方法

CFUUIDRef uuidRef = CFUUIDCreate(kCFAllocatorDefault);
NSString *uuidString = (NSString *)CFUUIDCreateString(NULL,uuidRef);

CFRelease(uuidRef);

请注意,您必须将uuidString保存在用户默认值或其他位置,因为您无法再次生成相同的uuidString.

您可以使用UIPasteboard存储生成的uuid.如果应用程序将被删除并重新安装,您可以从UIPasteboard读取旧的uuid.擦除设备时,粘贴板将被擦除.

在iOS 6中,他们引入了旨在创建UUID字符串的NSUUID类

他们还在iOS 6中添加@property(nonatomic, readonly, retain) NSUUID *identifierForVendor了UIDevice类

对于来自同一设备上运行的同一供应商的应用,此属性的值相同.对于来自不同供应商的同一设备上的应用程序以及不同供应商的不同设备上的应用程序,将返回不同的值.

如果应用程序在后台运行,则在用户在设备重新启动后第一次解锁设备之前,此属性的值可能为nil.如果值为nil,请稍后再次获取该值.

同样在iOS 6中,您可以使用AdSupport.framework中的ASIdentifierManager类.你有

@property(nonatomic, readonly) NSUUID *advertisingIdentifier

讨论与UIDevice的identifierForVendor属性不同,将向所有供应商返回相同的值.此标识符可能会更改 - 例如,如果用户删除了设备 - 因此您不应对其进行缓存.

如果应用程序在后台运行,则在用户在设备重新启动后第一次解锁设备之前,此属性的值可能为nil.如果值为nil,请稍后再次获取该值.

编辑:

注意advertisingIdentifier可能会返回

00000000-0000-0000-0000-000000000000

因为iOS中似乎有一个错误.相关问题:advertisingIdentifier和identifierForVendor返回"00000000-0000-0000-0000-000000000000"

对于你可以使用的Mac地址

#import <Foundation/Foundation.h>

@interface MacAddressHelper : NSObject

+ (NSString *)getMacAddress;

@end

implentation

#import "MacAddressHelper.h"
#import <sys/socket.h>
#import <sys/sysctl.h>
#import <net/if.h>
#import <net/if_dl.h>

@implementation MacAddressHelper

+ (NSString *)getMacAddress
{
  int                 mgmtInfoBase[6];
  char                *msgBuffer = NULL;
  size_t              length;
  unsigned char       macAddress[6];
  struct if_msghdr    *interfaceMsgStruct;
  struct sockaddr_dl  *socketStruct;
  NSString            *errorFlag = NULL;

  // Setup the management Information Base (mib)
  mgmtInfoBase[0] = CTL_NET;        // Request network subsystem
  mgmtInfoBase[1] = AF_ROUTE;       // Routing table info
  mgmtInfoBase[2] = 0;              
  mgmtInfoBase[3] = AF_LINK;        // Request link layer information
  mgmtInfoBase[4] = NET_RT_IFLIST;  // Request all configured interfaces

  // With all configured interfaces requested, get handle index
  if ((mgmtInfoBase[5] = if_nametoindex("en0")) == 0) 
    errorFlag = @"if_nametoindex failure";
  else
  {
    // Get the size of the data available (store in len)
    if (sysctl(mgmtInfoBase, 6, NULL, &length, NULL, 0) < 0) 
      errorFlag = @"sysctl mgmtInfoBase failure";
    else
    {
      // Alloc memory based on above call
      if ((msgBuffer = malloc(length)) == NULL)
        errorFlag = @"buffer allocation failure";
      else
      {
        // Get system information, store in buffer
        if (sysctl(mgmtInfoBase, 6, msgBuffer, &length, NULL, 0) < 0)
          errorFlag = @"sysctl msgBuffer failure";
      }
    }
  }
  // Befor going any further...
  if (errorFlag != NULL)
  {
    NSLog(@"Error: %@", errorFlag);
    return errorFlag;
  }
  // Map msgbuffer to interface message structure
  interfaceMsgStruct = (struct if_msghdr *) msgBuffer;
  // Map to link-level socket structure
  socketStruct = (struct sockaddr_dl *) (interfaceMsgStruct + 1);  
  // Copy link layer address data in socket structure to an array
  memcpy(&macAddress, socketStruct->sdl_data + socketStruct->sdl_nlen, 6);  
  // Read from char array into a string object, into traditional Mac address format
  NSString *macAddressString = [NSString stringWithFormat:@"%02X:%02X:%02X:%02X:%02X:%02X", 
                                macAddress[0], macAddress[1], macAddress[2], 
                                macAddress[3], macAddress[4], macAddress[5]];
  //NSLog(@"Mac Address: %@", macAddressString);  
  // Release the buffer memory
  free(msgBuffer);
  return macAddressString;
}

@end

使用:

NSLog(@"MAC address: %@",[MacAddressHelper getMacAddress]);

Answer 4

用这个:

NSUUID *id = [[UIDevice currentDevice] identifierForVendor];
NSLog(@"ID: %@", id);
