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?

[[UIDevice currentDevice] uniqueIdentifier]
保证每个设备都是唯一的。
答案 1 :(得分:40)
uniqueIdentifier(在iOS 5.0中已弃用。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代替[[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,粘贴板将被擦掉。
在iOS 6中,他们引入了旨在创建UUIDs字符串的NSUUID Class
他们还在iOS 6 @property(nonatomic, readonly, retain) NSUUID *identifierForVendor
中添加了UIDevice类
此属性的值对于来自的应用程序是相同的 在同一设备上运行的同一供应商。返回不同的值 对于来自不同供应商的同一设备上的应用程序,以及 不论供应商如何,都可以在不同的设备上使用。
如果应用程序正在运行,则此属性的值可能为nil 背景,在用户第一次解锁设备之前 设备重启后。如果值为nil,则等待并获取 这个价值会在以后再次出现。
同样在iOS 6中,您可以使用AdSupport.framework中的ASIdentifierManager课程。你有
@property(nonatomic, readonly) NSUUID *advertisingIdentifier
讨论与UIDevice的identifierForVendor属性不同, 将相同的值返回给所有供应商。该标识符可以 更改 - 例如,如果用户删除设备 - 所以你不应该 缓存它。
如果应用程序正在运行,则此属性的值可能为nil 背景,在用户第一次解锁设备之前 设备重启后。如果值为nil,则等待并获取 这个价值会在以后再次出现。
编辑:
注意advertisingIdentifier
可能会返回
00000000-0000-0000-0000-000000000000
因为iOS中似乎存在错误。相关问题:The advertisingIdentifier and identifierForVendor return "00000000-0000-0000-0000-000000000000"

对于Mac地址,您可以使用
#import <Foundation/Foundation.h>
@interface MacAddressHelper : NSObject
+ (NSString *)getMacAddress;
@end
实施
#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]);
答案 3 :(得分:5)
使用此:
NSUUID *id = [[UIDevice currentDevice] identifierForVendor];
NSLog(@"ID: %@", id);
答案 4 :(得分:4)
在IOS 5 [[UIDevice currentDevice] uniqueIdentifier]
已被弃用。
最好使用-identifierForVendor
或-identifierForAdvertising
。
