in appdelegate.h

@property (strong, nonatomic) mmdrawercontroller *drawer; 

in appdelegate.m file inside:

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {      uistoryboard *mainstory=[uistoryboard storyboardwithname:@"main" bundle:nil];  uiviewcontroller * leftdrawer = [mainstory instantiateviewcontrollerwithidentifier:@"menutableviewcontroller"];          uiviewcontroller * center = [mainstory instantiateviewcontrollerwithidentifier:@"homeviewcontroller"];     uinavigationcontroller *leftnav=[[uinavigationcontroller alloc]initwithrootviewcontroller:leftdrawer];         uinavigationcontroller *homnav=[[uinavigationcontroller alloc]initwithrootviewcontroller:center]; //drawer object mmdrawercontroller  drawer=[[mmdrawercontroller alloc]initwithcenterviewcontroller:homnav leftdrawerviewcontroller:leftnav rightdrawerviewcontroller:nil]; 

//dont write

_window.rootviewcontroller=drawcontroller; [_window makekeyandvisible]; comment these lines if write.

  appdelegate *app=(appdelegate *)[[uiapplication sharedapplication]delegate];     app.window.rootviewcontroller = app.drawer;     [app.window makekeyandvisible];
