How to Use DTO's in Objective C -


I am using data transfer objects in the food, such as 

  public class accountDEM {Private string username; Private string userAuthToken; Personal Ind users_id; Public Zero SatusName (string _username) {this.userName = _userName; } Public string getuserName () {return user name; } ...}   
 How can I use the same in Objective-C? Probably "the purpose of the objective C" will serve the purpose I think. But some people can tell it in detail, how to use the Objective-C property to write the DTO and how to use them effectively and to keep memory safe (to avoid memory leaks).  
 If possible, please code above OBJ C.   
 
 
  @interface accountDEM @property (nonatomic, retain) NSString * Username; @property (nontomic, write) NSString * userAuthToken; @property (nanatomic) int user_id; @end @implementaion @ synthesis user name; @ Userstom; Synthesize; @ Synthesis user_ID; You can read    for properties @end

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
