获取手机唯一标识码

现在活得手机唯一标示码,不太容易,我也是搞了好半天才弄到方法,在此分享给大家,顺便总结一下.

1.首先去github下载 sskeychain-master包,我们需要里面的SSKeychain.h和SSKeychain.m文件即可

2.然后建一个继承NSobject得类

3.在里面写上:

#import <Foundation/Foundation.h>

@interface UUID : NSObject

+ (NSString*) gen_uuid;

@end

.m里

#import "UUID.h"

@implementation UUID

+(NSString*) gen_uuid

{

    

    CFUUIDRef uuid_ref=CFUUIDCreate(nil);

    

    CFStringRef uuid_string_ref =CFUUIDCreateString(nil, uuid_ref);

    

    CFRelease(uuid_ref);

    

    NSString *uuid=[NSStringstringWithString:(__bridgeNSString * _Nonnull)(uuid_string_ref)];

    

    CFRelease(uuid_string_ref);

    

    return uuid;

    

}

@end

然后就可以调用了

#import "ViewController.h"

#import "SSKeychain.h"

#import "UUID.h"

#define kService [NSBundle mainBundle].bundleIdentifier

#define kAccount @"K626P85663.com.tzd.mofi2"//这个码是我们自己定的

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

    [superviewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

    

    //获取UUID，保存在钥匙串中（蓝色部分为标识，最好为app唯一标识，通过此标识查找保存的钥匙串）

    

    

    //获取设备唯一码

    

    if(![SSKeychainpasswordForService:kServiceaccount:kAccount])

        

    {

        

        NSString *uuid = [UUIDgen_uuid];

        

        [SSKeychainsetPassword:uuid forService:kServiceaccount:kAccount];

        

    }

    

    NSString *devicenumber = [SSKeychainpasswordForService:kServiceaccount:kAccount];

    

    这个字符串就是我们需要的了! 

}

测试过 得到的标识码基本不会变
