效果图如下：
前言
左滑重点不在动画效果的实现，而在于左边视图事件响应后，怎么push进入主视图的NavigationController，如果主视图是TabBar的话，要获取当前TabBar的selecteItem，并push进入对应的导航容器中，正文以最为典型的TabBar作为Main主视图。
实现步骤：
1、首先实现工具类EVNSideSlideViewController，支持左滑和右滑，左视图-主视图-右视图，记得用的时候要将EVNSideSlideViewController做为你的根视图；
2、左右视图的设计及主视图控制器的设计，按照原来做；
3、使用单例类记录主视图TabBar的选择状态，以便于push到当前页面所在的NavigationController中；
4、左右视图单击事件处理，详情见，正文的第三部分。
下面的BaseViewController可以改成UIViewController

二、CommonHelper 单例记录TabBar的状态
CommonHelper.h
#import#import@interfaceCommonHelper:NSObject@property(strong,nonatomic)UIViewController*rootViewController; + (instancetype)shareInstance;- (void)setObjValue;@end
CommonHelper.m
#import"CommonHelper.h"staticid_instance;@implementationCommonHelper///**// * 只要系统中引用了该类，程序运行，就会主动调用load（不用手动调用，而且只会加载1次）// *///+ (void)load//{// _instance = [[CommonHelper alloc] init];//}+ (instancetype)allocWithZone:(struct_NSZone *)zone{staticdispatch_once_tonceToken;dispatch_once(&onceToken, ^{ _instance = [superallocWithZone:zone]; });return_instance;} + (instancetype)shareInstance{staticdispatch_once_tonceToken;dispatch_once(&onceToken, ^{ _instance = [[selfalloc] init]; });return_instance;}- (id)copyWithZone:(NSZone*)zone{return_instance;}- (id)mutableCopyWithZone:(NSZone*)zone{return_instance;}// 设置当前window的根视图- (void)setObjValue{ [_instance setRootViewController:[[UIApplicationsharedApplication] keyWindow].rootViewController];}@end
三、左、右视图点击事件触发写法
- (void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath{ CommonHelper *common = [CommonHelper shareInstance]; [common setObjValue];NSLog(@"%@",NSStringFromClass([common.rootViewControllerclass])); EVNSideSlideViewController *sideSlideViewController = (EVNSideSlideViewController *)common.rootViewController; [sideSlideViewController showMainViewController];// NSLog(@"%@", NSStringFromClass(sideSlideViewController.mainViewController));BuyerTabbarCtrl *toolController = (BuyerTabbarCtrl *)sideSlideViewController.mainViewController;NSIntegerselectIndex = toolController.selectedIndex;// NSLog(@"%@", NSStringFromClass(toolController.viewControllers[0]));// 关于AboutMaibeiViewController * aboutMaibeiViewController = [[AboutMaibeiViewController alloc] init]; aboutMaibeiViewController.hidesBottomBarWhenPushed =YES; [toolController.viewControllers[selectIndex] pushViewController:aboutMaibeiViewController animated:YES];}
