Cocos2d Save most recent login to multiple accounts for up to one months

Using a single case to manage, the data is present in the local XML file in the format below

<?XML version= "1.0" encoding = "Utf-8"?><RootNode>    <UserInfo Time= "1449905923">        < Account>abc002</ Account>        <Password>a123456</Password>    </UserInfo>    <UserInfo Time= "1430905758">        < Account>abc001</ Account>        <Password>a123456</Password>    </UserInfo></RootNode>

First define some of the number of information to be used

#include"AccountManager.h"#include"external/tinyxml2/tinyxml2.h"#defineAccount_file_name "Useraccounts.xml"#defineAccount_save_count 5//number of accounts saved#defineSeconds_of_day 86400//number of seconds in a day#defineLimit_day 30LL//Effective DaysAccountmanager* Accountmanager::m_pself =nullptr;structLoginaccountinfo {stringStraccount;//Account Number     stringstrpassword;//Password     stringstrdate;//Last Login Date};

Gets the previously saved account information when constructing the object

Accountmanager::accountmanager () {stringstrpath = Fileutils::getinstance ()->getwritablepath () +Account_file_name; if(Fileutils::getinstance ()isfileexist (strpath)) {        //extract account information to memoryTinyxml2::xmldocument *pxmldocument =Newtinyxml2::xmldocument; Pxmldocument-LoadFile (Strpath.c_str ()); Auto Pxmlrootnode= pxmldocument->rootelement (); Auto Pxmlnodeuinfo= pxmlrootnode->firstchildelement ();  while(pxmlnodeuinfo) {Loginaccountinfo accinfo; Accinfo.strdate= Pxmlnodeuinfo->attribute (" Time"); Auto Pxmlnodeaccunt= pxmlnodeuinfo->firstchildelement (); Accinfo.straccount= pxmlnodeaccunt->GetText (); Auto Pxmlnodepassword= pxmlnodeaccunt->nextsiblingelement (); Accinfo.strpassword= pxmlnodepassword->GetText ();            M_vectoraccountsinfo.push_back (Accinfo); Pxmlnodeuinfo= pxmlnodeuinfo->nextsiblingelement (); }    }}

Save account information to file

//Save account to filevoidAccountmanager::saveaccountinfotofile (Const string&straccounts,Const string&strpassword) {    //Sort AccountsAuto Iteratorstr =M_vectoraccountsinfo.begin ();  for(; Iteratorstr! = M_vectoraccountsinfo.end (); + +iteratorstr) {        if((*iteratorstr). Straccount = =straccounts)            {m_vectoraccountsinfo.erase (ITERATORSTR);  Break; }    }    //determine if there are more than 5 saved accounts    if(M_vectoraccountsinfo.size () >=account_save_count) M_vectoraccountsinfo.pop_back ();    Loginaccountinfo Accinfo; Accinfo.straccount=straccounts; Accinfo.strpassword=strpassword; Accinfo.strdate=getcurrentdate ();    M_vectoraccountsinfo.insert (M_vectoraccountsinfo.begin (), accinfo); Tinyxml2::xmldocument*pxmldoc =Newtinyxml2::xmldocument (); //StatementTinyxml2::xmldeclaration *pxmldeclare = pxmldoc->newdeclaration ("XML version=\ "1.0\" encoding = \ "Utf-8\"");    ASSERT (Pxmldeclare); if(Pxmldeclare = = nullptr)return; Pxmldoc-Linkendchild (Pxmldeclare); //root nodeTinyxml2::xmlelement *pxmlrootnode = pxmldoc->newelement ("RootNode"); //Add Account sub-node     for(size_t i =0; I < m_vectoraccountsinfo.size (); i++) {Auto Pxmlnodeuinfo= Pxmldoc->newelement ("UserInfo"); Pxmlnodeuinfo->setattribute (" Time", m_vectoraccountsinfo.at (i). STRDATE.C_STR ()); Auto Pxmlnodeaccount= Pxmldoc->newelement (" Account"); Pxmlnodeaccount->linkendchild (pxmldoc->NewText (m_vectoraccountsinfo.at (i). STRACCOUNT.C_STR ())); Pxmlnodeuinfo-Linkendchild (Pxmlnodeaccount); Auto Pxmlnodepassword= Pxmldoc->newelement ("Password"); Pxmlnodepassword->linkendchild (pxmldoc->NewText (m_vectoraccountsinfo.at (i). STRPASSWORD.C_STR ())); Pxmlnodeuinfo-Linkendchild (Pxmlnodepassword); Pxmlrootnode-Linkendchild (Pxmlnodeuinfo); } Pxmldoc-Linkendchild (Pxmlrootnode); //Save to file    if(pxmldoc) {stringstrpath = Fileutils::getinstance ()->getwritablepath () +Account_file_name; Pxmldoc->savefile (Fileutils::getinstance ()Getsuitablefopen (strpath). C_STR ()); DeletePxmldoc; }}

// Gets the current time total seconds value string accountmanager::getcurrentdate () {    = time (nullptr);     string strdate;     = Stringutils::format ("%lld", Lltimestamp);     return strdate;}

//determine if the account is saved more than the limit daysBOOLAccountmanager::isacccountoutofdate (Const string&Straccount) {     for(Auto accinfo:m_vectoraccountsinfo) {if(Accinfo.straccount = =Straccount) {            Long LongLllogintime =Atoll (Accinfo.strDate.c_str ()); Long LongLlnowtime =Atoll (Getcurrentdate (). C_STR ()); Long LongLlday = (llnowtime-lllogintime)/Seconds_of_day; if(Llday >limit_day) {                return true; }            return false; }    }    return false;}

Here is the data capture that the UI section uses, and the UI section uses the TableView

// get all accounts vector<string> accountmanager::getallaccount () {    vector<string > vectoraccounts;      for (auto Accinfo:m_vectoraccountsinfo)    {        vectoraccounts.push_back (accinfo.straccount);    }     return vectoraccounts;}

The above is only the data management, the UI part of the code, the idea is that the login interface by default load fill account password to determine whether the account is more than a given number of days (here is 30 days, the top macro definition), get the data list when all the accounts to fill define the UI with TableView, refresh the account information when logging in, put the most recent landing in front (the code is written), and then save to local.
