objective c - MFSideMenu is not working in iOS? -

-

hi have followed github page add mfsidemenu , showing following error.

undefined symbols architecture x86_64:   "_objc_class_$_mfsidemenucontainerviewcontroller", referenced from:       objc-class-ref in appdelegate.o ld: symbol(s) not found architecture x86_64 clang: error: linker command failed exit code 1 (use -v see invocation)

this appdelegate 

- (viewcontroller *)democontroller {     uistoryboard *mainstoryboard = [uistoryboard storyboardwithname:@"main" bundle: nil];     viewcontroller *main = (viewcontroller *)[mainstoryboard instantiateviewcontrollerwithidentifier:@"home"];      return  main; }  - (uinavigationcontroller *)navigationcontroller {     return [[uinavigationcontroller alloc]             initwithrootviewcontroller:[self democontroller]]; }  - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     // override point customization after application launch.     leftmenucontroller *leftmenuviewcontroller = [[leftmenucontroller alloc] init];      mfsidemenucontainerviewcontroller *container = [mfsidemenucontainerviewcontroller                                                     containerwithcenterviewcontroller:[self navigationcontroller]                                                     leftmenuviewcontroller:leftmenuviewcontroller                                                     rightmenuviewcontroller:nil];     self.window.rootviewcontroller = container;     [self.window makekeyandvisible];     return yes; }

in general, occur when code boxview not being compiled target correctly.

you need ensure target you're building has corresponding box checked mfsidemenucontainerviewcontroller.m implementation file.

a 'clean , build' never hurts, either.
