我正在尝试为我的应用设置侧边栏导航菜单。我正在使用 MMDrawerController 库，但遇到了问题。我添加了一个按钮并使用这些方法来调用侧边栏：

-(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];
}

我正在使用带有视图控制器的导航控制器，我在其中调用此方法。此视图控制器称为 ViewController2。

每当我按下按钮拉出侧面菜单时，它都会崩溃并返回此错误：

*由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“-[ViewController2 mm_drawerController]：无法识别的选择器发送到实例 0x835b440”

我究竟做错了什么？

看看这个例子，你是否尝试过类似的事情，以防你使用导航

（或交换视图以防万一）

[(UINavigationController*)self.mm_drawerController.centerViewController pushViewController: 动画:YES];
