正在iOS中获取设备ID或Mac地址[重复]

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

uniqueIdentifier(在iOS 5.0中不推荐使用。相反,请创建特定于应用程序的唯一标识符。)

文件建议使用 CFUUIDCreate [[UIDevice currentDevice] uniqueIdentifier]

下面是您如何在应用程序中生成唯一id的方法

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

CFRelease(uuidRef);

请注意,必须将UUIString保存在用户默认值或其他位置,因为无法再次生成相同的UUIString。

UIPasteboard

在iOS 6中,他们引入了 NSUUID Class 设计用于创建UUID字符串的

@property(nonatomic, readonly, retain) NSUUID *identifierForVendor 到 UIDevice 班

同一供应商在同一设备上运行。返回一个不同的值 对于来自不同供应商的同一设备上的应用,以及 不同设备上的应用程序,不考虑供应商。

后台,在用户首次解锁设备之前 设备重新启动后。如果值为nil,请等待并获取 该值将在稍后再次显示。

在iOS 6中也可以使用 ASIdentifierManager 从AdSupport.framework初始化。给你

@property(nonatomic, readonly) NSUUID *advertisingIdentifier

讨论与UIDevice的identifierForVendor属性不同, 更改例如,如果用户擦除设备,则不应

如果应用程序正在中运行,则此属性的值可能为零 后台,在用户首次解锁设备之前 设备重新启动后。如果值为nil,请等待并获取

advertisingIdentifier 可能会回来

00000000-0000-0000-0000-000000000000

The advertisingIdentifier and identifierForVendor return "00000000-0000-0000-0000-000000000000"

你可以使用Mac地址

#import <Foundation/Foundation.h>

@interface MacAddressHelper : NSObject

+ (NSString *)getMacAddress;

@end

#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]);

使用以下命令:

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

在IOS 5中 [[UIDevice currentDevice] uniqueIdentifier]

-identifierForVendor 或 -identifierForAdvertising

在这里,我们可以使用Asp.net C#代码找到IOS设备的mac地址。。。
