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;}

2).在-application:performActionForShortcutItem:completionHandler:方法中实现点击快捷菜单的方法：

//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"])    {        [email protected]"嘿嘿";    }    else if([shortcutItem.localizedTitle isEqualToString:@"呵呵"])    {        [email protected]"呵呵";    }    else if([shortcutItem.localizedTitle isEqualToString:@"搜索"])    {        [email protected]"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：

3DTouch按压的时候生成的预览

peek时上拉出现的菜单

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;}

注册3DTouch

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        [email protected][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;}
