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

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。

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];}

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
