MMDrawerController未识别选择器

Question

我正在尝试为我的应用程序设置一个侧边栏导航菜单。我正在使用MMDrawerController库，但遇到了一个问题。我添加了一个按钮并使用这些方法调用侧栏：

-(void)setupLeftMenuButton{
    MMDrawerBarButtonItem * leftDrawerButton = [[MMDrawerBarButtonItem alloc] initWithTarget:self action:@selector(leftDrawerButtonPress:)];
    [self.navigationItem setLeftBarButtonItem:leftDrawerButton animated:YES];
}

-(void)leftDrawerButtonPress:(id)sender{
    [self.mm_drawerController toggleDrawerSide:MMDrawerSideLeft animated:YES completion:nil];
}

我使用的是一个带有视图控制器的导航控制器，我在其中调用这个方法。这个视图控制器称为ViewController2。

每当我按下按钮来取出sidemenu时，它就会崩溃并返回此错误：

*由于“NSInvalidArgumentException”异常终止应用程序，原因：'-ViewController2 2 mm_drawerController:发送到实例0x835b440的未识别选择器‘

我做错了什么？

看看这个例子，您是否尝试过类似的方法，以防止您使用导航

(或交换视图以防止出现这种情况)

(UINavigationController*)self.mm_drawerController.centerViewController pushViewController:动画:是的；
