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。




1、工具类EVNSideSlideViewController实现

下面的BaseViewController可以改成UIViewController

2、CommonHelper 单例记录TabBar的状态


CommonHelper.h

[Objective-C] 纯文本查看 复制代码
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface CommonHelper : NSObject<NSCopying, NSMutableCopying>
@property (strong, nonatomic) UIViewController *rootViewController;

 + (instancetype)shareInstance;
- (void)setObjValue;

@end



CommonHelper.m

[Objective-C] 纯文本查看 复制代码
#import "CommonHelper.h"

 static id _instance;

@implementation CommonHelper


///**
// *  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
{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _instance = [super allocWithZone:zone];
    });
    return _instance;
}

 + (instancetype)shareInstance
{
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        _instance = [[self alloc] 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:[[UIApplication sharedApplication] keyWindow].rootViewController];
}

@end





3、左、右视图点击事件触发写法

[Objective-C] 纯文本查看 复制代码
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    CommonHelper *common = [CommonHelper shareInstance];
    [common setObjValue];

    NSLog(@"%@", NSStringFromClass([common.rootViewController class]));
    EVNSideSlideViewController *sideSlideViewController = (EVNSideSlideViewController *)common.rootViewController;
    [sideSlideViewController showMainViewController];

//    NSLog(@"%@", NSStringFromClass(sideSlideViewController.mainViewController));

    BuyerTabbarCtrl *toolController = (BuyerTabbarCtrl *)sideSlideViewController.mainViewController;
    NSInteger selectIndex = toolController.selectedIndex;

//    NSLog(@"%@", NSStringFromClass(toolController.viewControllers[0]));

        // 关于
    AboutMaibeiViewController * aboutMaibeiViewController = [[AboutMaibeiViewController alloc] init];
    aboutMaibeiViewController.hidesBottomBarWhenPushed = YES;
    [toolController.viewControllers[selectIndex] pushViewController:aboutMaibeiViewController animated:YES];
}
