MMDrawerController无法识别的选择器 [英] MMDrawerController unrecognized selector

问题描述

我想为我的应用程式设定siderbar导览选单。我使用MMDrawerController lib，但我遇到了一个问题。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]; 
} 
  

我使用一个带有View控制器的导航控制器， m调用这个方法。这个viewcontroller被称为ViewController2。

每当我按下按钮拉出sidemenu，它崩溃，并返回这个错误：

* 由于未捕获的异常NSInvalidArgumentException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'

我做错了什么？

查看示例，如果您使用的是导航，请尝试使用

（或者如果不是则交换视图）

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

I'm trying to setup a siderbar navigation menu for my app. I'm using the MMDrawerController lib, but I'm running into an issue. I've added a button and use these methods to call the sidebar:

-(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];
}

I'm using a Navigation Controller with a View Controller attached in which I'm calling this method. This viewcontroller is called ViewController2.

Whenever I press the button to pull out the sidemenu, it crashes and returns this error:

* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ViewController2 mm_drawerController]: unrecognized selector sent to instance 0x835b440'

What am I doing wrong?

解决方案

Take a look at the example have you tried something like in case you are using navigation

(or swapping view in case you are not)

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