用MMDrawerController实现侧滑

我这里使用的是cocoapods来安装的MMDrawerController库，细节不再详述。

CenterViewController

在加载本视图控制器的时候，由于其它视图控制器的切换可能会关闭 通过手势滑动打开抽屉的模式，因此需要设置一下:

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

1. 首先给导航栏添加按钮

    UIBarButtonItem* leftBarBtnItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(pressLeftBtn)];    self.navigationItem.leftBarButtonItem = leftBarBtnItem;    UIBarButtonItem* rightBarBtnItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemOrganize target:self action:@selector(pressRightBtn)];    self.navigationItem.rightBarButtonItem = rightBarBtnItem;

1. 添加双击手势

    UITapGestureRecognizer* doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTap:)];    //单手指双击    [doubleTap setNumberOfTapsRequired:2];    [self.view addGestureRecognizer:doubleTap];    //双手指双击    UITapGestureRecognizer * twoFingerDoubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(twoFingerDoubleTap:)];    [twoFingerDoubleTap setNumberOfTapsRequired:2];    //两个手指  默认为一个    [twoFingerDoubleTap setNumberOfTouchesRequired:2];    [self.view addGestureRecognizer:twoFingerDoubleTap];

1. 实现按钮的事件函数

-(void)pressLeftBtn{     //self.mm_drawerController通过遍历循环拿到之前在AppDelegate中声明的那个MMDrawerController属性，然后判断是否为打开状态，如果是就关闭，否就是打开    [self.mm_drawerController toggleDrawerSide:MMDrawerSideLeft animated:YES completion:nil];}-(void)pressRightBtn{    [self.mm_drawerController toggleDrawerSide:MMDrawerSideRight animated:YES completion:nil];}

1. 实现双击屏幕的事件函数

/*边缘反弹*///单手双击-(void)doubleTap:(UITapGestureRecognizer*) gesture{    [self.mm_drawerController bouncePreviewForDrawerSide:MMDrawerSideLeft completion:nil];}//双手指双击-(void)twoFingerDoubleTap:(UITapGestureRecognizer*) gesture{    [self.mm_drawerController bouncePreviewForDrawerSide:MMDrawerSideRight completion:nil];}



LeftViewController | RightViewController

1. 实现 UITableViewDataSource、UITableViewDelegate 的相关协议函数
2. 当选中tableView的cell后，跳转到 ShowViewControll 视图控制器中

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{    LitterLShowViewController *showVC = [[LitterLShowViewController alloc]init];    showVC.title = [NSString stringWithFormat:@"Left-Demo%ld",indexPath.row];    //拿到我们的LitterLCenterViewController，让它去push    UINavigationController* nav = (UINavigationController*)self.mm_drawerController.centerViewController;    [nav pushViewController:showVC animated:NO];    //当我们push成功之后，关闭我们的抽屉    [self.mm_drawerController closeDrawerAnimated:YES completion:^(BOOL finished) {        //设置打开抽屉模式为MMOpenDrawerGestureModeNone，也就是没有任何效果。        [self.mm_drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeNone];    }];}

需要注意的是，push成功之后，必须要关闭掉我们的抽屉效果。否则，显示ShowViewController的时候仍然是抽屉的样式

ShowViewController

• 在该视图控制器中只设置了背景色为白色。

• 选中cell push进入ShowViewController之后，当你轻轻往右滑动的时候 其实它已经加载了centerViewController中的viewWillAppear这个方法，这个方法打开了通过手势滑动打开抽屉的模式 ，因此导致没有回到centerViewController，而显示的是抽屉模式。你在ShowViewController的viewWillAppear这个方法中加上关闭通过手势滑动打开抽屉的模式就可以了

AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    // Override point for customization after application launch.    //1、初始化控制器    UIViewController* centerVC = [[LitterLCenterViewController alloc]init];    UIViewController* leftVC = [[LitterLLeftViewController alloc]init];    UIViewController* rightVC = [[LitterLRightViewController alloc]init];    //2、初始化导航控制器    UINavigationController* centerNvaVC = [[UINavigationController alloc]initWithRootViewController:centerVC];    UINavigationController* leftNvaVC = [[UINavigationController alloc]initWithRootViewController:leftVC];    UINavigationController* rightNvaVC = [[UINavigationController alloc]initWithRootViewController:rightVC];    //3、使用MMDrawerController    self.drawerController = [[MMDrawerController alloc]initWithCenterViewController:centerNvaVC leftDrawerViewController:leftNvaVC rightDrawerViewController:rightNvaVC];    //4、设置打开/关闭抽屉的手势    self.drawerController.openDrawerGestureModeMask = MMOpenDrawerGestureModeAll;    self.drawerController.closeDrawerGestureModeMask =MMCloseDrawerGestureModeAll;    //5、设置左右两边抽屉显示的多少    self.drawerController.maximumLeftDrawerWidth = 300.0;    self.drawerController.maximumRightDrawerWidth = 200.0;    //6、初始化窗口、设置根控制器、显示窗口    self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];    [self.window setRootViewController:self.drawerController];    [self.window makeKeyAndVisible];    return YES;}

总体上大致流程就是如此了！
