用MMDrawerController实现侧滑

本文主要是介绍用MMDrawerController实现侧滑，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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pushUINavigationController* 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MMDrawerControllerself.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！
