```
+ (NSString *)UUID {
    //MARK:此处的 @"5CKSJSE23P.com.haodf.mainGroup" 字串不能动，否则会导致获取的值错误或者 nil
    KeychainItemWrapper *wrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"HuangyibiaoAppID" accessGroup:@"com.huangyibiao.test.group"];
    NSString *UUID = [wrapper objectForKey:(__bridge id)kSecValueData];
    
    if (UUID.length == 0) {
      UUID = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
      [wrapper setObject:UUID forKey:(__bridge id)kSecValueData];
    }
  
  return UUID;
}
```

 
注意事项
请自行修改对应的key及导入KeychainItemWrapper这个库！上面提供的只是代码片段，不是完整的代码！
