因为刚开年，所以最近公司比较闲，看到以前并不是我接手的项目中有这种抽屉效果的控制器，比较感兴趣，便对MMDrawerController研究起来。也方便自己忘记之后查阅,另外也希望对大家有所帮助（PS:以前都是上面一个导航栏，下面一个tabbar的项目居多，所以对这种抽屉控制器不是很了解）.

1.首先，到GitHub上把MMDrawerController下下来，然后倒入到项目中。当然你用cocoapods倒入也行。看你心情呗O(∩_∩)O

MMDrawerController

2.接下来就在appdelegate中撸我们的代码了。先倒入各个控制器哈。

#import"MMDrawerController.h"
#import"rightViewController.h"
#import"centerViewController.h"
#import"leftViewController.h"
#import"MainNavViewController.h"

然后就是在didFinishLaunching中设置相关的控制了，其实跟平时项目的区别就是多了一个抽屉控制器。

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {
self.window= [[UIWindowalloc]initWithFrame:[UIScreenmainScreen].bounds];
//左中右三个控制器
rightViewController*rightVc = [[rightViewControlleralloc]init];
leftViewController*leftVc = [[leftViewControlleralloc]init];
centerViewController*centerVc = [[centerViewControlleralloc]init];
//导航控制器
MainNavViewController*rightNavVc = [[MainNavViewControlleralloc]initWithRootViewController:rightVc];
MainNavViewController*leftNavVc = [[MainNavViewControlleralloc]initWithRootViewController:leftVc];
MainNavViewController*centerNavVc = [[MainNavViewControlleralloc]initWithRootViewController:centerVc];
//抽屉控制器
self.mmDrawerController= [[MMDrawerControlleralloc]initWithCenterViewController:centerNavVcleftDrawerViewController:leftNavVcrightDrawerViewController:rightNavVc];
//    关闭模式手势
self.mmDrawerController.closeDrawerGestureModeMask = MMCloseDrawerGestureModeAll;
//    打开模式手势
self.mmDrawerController.openDrawerGestureModeMask = MMOpenDrawerGestureModeAll;
//    抽屉控制器的最长宽度
self.mmDrawerController.maximumLeftDrawerWidth = 200;
[self.windowmakeKeyAndVisible];
self.window.rootViewController=self.mmDrawerController;
returnYES;
}

其实在这里就已经可以实现抽屉控制器的基本效果的了。但是要如下图的效果还得加一丢丢代码。

center控制器

然后我们在center控制器导航栏的leftBarButton上自定义一个button,添加点击事件等等，这应该不难哈。记得要导入相关的类。

#import "UIViewController+MMDrawerController.h"

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.title = @"Demo";
    self.view.backgroundColor = [UIColor greenColor];
    //UIBarButtonItem的自定义的分类方法
    self.navigationItem.leftBarButtonItem = [UIBarButtonItem initWithTarget:self action:@selector(leftBtnClick) image:@"菜单 (1)" hightImage:@"菜单"];
}

-(void)leftBtnClick{
//    将左边的控制器打开
    [self.mm_drawerController toggleDrawerSide:MMDrawerSideLeft animated:YES completion:nil];
}

下面就是left控制器的代码哈，就是在view上添加了一个tableView。

#import "leftViewController.h"
#import "pushViewController.h"
#import "UIViewController+MMDrawerController.h"
#import "MainNavViewController.h"

@interface leftViewController ()<UITableViewDelegate,UITableViewDataSource>

@end

@implementation leftViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
       self.view.backgroundColor = [UIColor blueColor];
    
    UITableView *tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
    tableView.delegate = self;
    tableView.dataSource = self;
    [self.view addSubview:tableView];
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return 10;
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
    
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"cell"];
    }

    cell.detailTextLabel.text = [NSString stringWithFormat:@"%zd",indexPath.row];
    
    return cell;
}

点击cell跳转控制器

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    pushViewController *pushVc = [[pushViewController alloc] init];
    pushVc.title = [NSString stringWithFormat:@"%zd",indexPath.row];
    //取到center控制器    
    MainNavViewController *mainNavVc = (MainNavViewController *)self.mm_drawerController.centerViewController;
    [mainNavVc pushViewController:pushVc animated:YES];
   //关闭了控制器之后记得将模式设置为None
    [self.mm_drawerController closeDrawerAnimated:YES completion:^(BOOL finished) {
        [self.mm_drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeNone];
    }];
    
}

最后记得在center控制器的viewDidAppear中打开滑动的手势

-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
    
    [self.mm_drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeAll];
}

最基本的使用大概就是这样的，有不足的地方希望大家多多指导。
