1.桌面快捷菜单项

效果如图：

点击之后的效果如图：

接下来看下具体实现：
1).在-application:didFinishLaunchingWithOptions：
方法中用-setShortcutItems:方法来添加快捷菜单项。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //3D Touch按压程序图标的快捷项
    //快捷菜单的图标
    UIApplicationShortcutIcon *icon1=[UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeCaptureVideo];
    UIApplicationShortcutIcon *icon2=[UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeAdd];
    UIApplicationShortcutIcon *icon3=[UIApplicationShortcutIcon iconWithTemplateImageName:@"search"];
    //快捷菜单
    UIApplicationShortcutItem *item1=[[UIApplicationShortcutItem alloc]initWithType:@"1"
                                                                     localizedTitle:@"嘿嘿"
                                                                  localizedSubtitle:nil
                                                                               icon:icon1
                                                                           userInfo:nil];
    UIApplicationShortcutItem *item2=[[UIApplicationShortcutItem alloc]initWithType:@"1"
                                                                     localizedTitle:@"呵呵"
                                                                  localizedSubtitle:@"干嘛去洗澡"
                                                                               icon:icon2
                                                                           userInfo:nil];
    UIApplicationShortcutItem *item3=[[UIApplicationShortcutItem alloc]initWithType:@"1"
                                                                     localizedTitle:@"搜索"
                                                                  localizedSubtitle:nil
                                                                               icon:icon3
                                                                           userInfo:nil];
    //设置app的快捷菜单
    [[UIApplication sharedApplication] setShortcutItems:@[item1,item2,item3]];
    //导航
    self.window.rootViewController=[[UINavigationController alloc]initWithRootViewController:[ViewController new]];
    return YES;
}

//3D Touch按压程序图标的快捷项时触发的方法
-(void)application:(UIApplication )application performActionForShortcutItem:(UIApplicationShortcutItem )shortcutItem completionHandler:(void (^)(BOOL))completionHandler
{
    NSString title;
    if([shortcutItem.localizedTitle isEqualToString:@"嘿嘿"])
    {
        title=@"嘿嘿";
    }
    else if([shortcutItem.localizedTitle isEqualToString:@"呵呵"])
    {
        title=@"呵呵";
    }
    else if([shortcutItem.localizedTitle isEqualToString:@"搜索"])
    {
        title=@"搜索";
    }
    //这里就弹个框子意思一下
    //由于UIAlertView在iOS 9被废弃，因此选用UIAlertController
    UIAlertController alertController=[UIAlertController alertControllerWithTitle:@"提示"
                                                                           message:[NSString stringWithFormat:@"你点击了“%@”",title]
                                                                    preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction action=[UIAlertAction actionWithTitle:@"知道了"
                                                   style:UIAlertActionStyleDefault
                                                 handler:^(UIAlertAction  action) {
                                                     [alertController dismissViewControllerAnimated:YES completion:nil];
                                                 }];
    [alertController addAction:action];
    [self.window.rootViewController presentViewController:alertController
                                                 animated:YES
                                               completion:nil];
}

2.程序内的3DTouch按压操作：

1).首先，实现3DTouch的视图控制器要遵守：
UIViewControllerPreviewingDelegate协议，它有2个required级别的协议方法：
-previewingContext:viewControllerForLocation:
以及
-previewingContext:commitViewController:

2).检测3DTouch是否可用，并注册3DTouch：

检测3D Touch是否可用

-(BOOL)is3DTouchAvailiable
{
 if(self.traitCollection.forceTouchCapability==UIForceTouchCapabilityAvailable)
        return YES;
    return NO;
}

if([self is3DTouchAvailiable])
    {
        [self registerForPreviewingWithDelegate:self sourceView:self.view];
    }

3).实现协议方法：

-(UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{
    NSIndexPath *indexPath=[_tbVew indexPathForRowAtPoint:CGPointMake(location.x, location.y-64)];
    if(indexPath)
    {
        DetailViewController *detail=[[DetailViewController alloc]init];
        detail.title=_dataArray[indexPath.row];
        //detail.preferredContentSize=CGSizeMake(300, 300);
        __weak typeof(self) wkSelf=self;
        //------------上拉时的菜单-------------------
        //置顶及其点击逻辑
        UIPreviewAction *topAction=[UIPreviewAction actionWithTitle:@"置顶" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * action, UIViewController * previewViewController) {
            [wkSelf.dataArray exchangeObjectAtIndex:indexPath.row withObjectAtIndex:0];
            [wkSelf.tbVew reloadData];
            [wkSelf showAlert:@"提示" body:@"已置顶"];
        }];
        //删除及其点击逻辑
        UIPreviewAction *deleteAction=[UIPreviewAction actionWithTitle:@"删除" style:UIPreviewActionStyleDestructive handler:^(UIPreviewAction *action, UIViewController * previewViewController) {
            [wkSelf.dataArray removeObjectAtIndex:indexPath.row];
            [wkSelf.tbVew reloadData];
            [wkSelf showAlert:@"警告" body:@"已删除"];
        }];
        //传递上拉菜单项给detail
        detail.actions=@[topAction,deleteAction];
        return detail;
    }
    return nil;
}
-(void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit
{
    [self showViewController:viewControllerToCommit sender:self];
}

4).要previewing的视图控制器必须实现：
-(NSArray<id<UIPreviewActionItem>> *)previewActionItems方法，该方法定义了peek时上拉出来的菜单：

/**peek时上拉出来的菜单*/
-(NSArray<id<UIPreviewActionItem>> *)previewActionItems
{
    return self.actions;
}
