    IOS 3DTouch技术使用

    简介

    3D Touch是一种立体触控技术,被苹果称为新一代多点触控技术,是在Apple Watch上采用的Force Touch,屏幕可感应不同的感压力度触控。3D Touch,苹果iPhone 6s的新功能。有PeekPop两种新手势。3D-Touch技术,相对于多点触摸在平面二维空间的操作,3D-Touch技术增加了对力度和手指面积的感知,可以通过长按快速预览/查看你想要的短信/图片/超链接等内容,PeekPop手势的响应时间可迅捷到10ms15ms

    应用外3DTouch

    介绍

    应用外3DTouch技术是指应用处于桌面ICON快捷菜单,这种设计极大的提高应用使用的便捷性,更加快速定位到常用功能的使用。样式如下图:

    Info.plist方式实现3DTouch技术

    UIApplicationShortcutItems:数组中的元素就是我们的那些快捷选项标签。
    UIApplicationShortcutItemTitle:标签标题(必填)
    UIApplicationShortcutItemType:标签的唯一标识 (必填)
    UIApplicationShortcutItemIconType:使用系统图标的类型,如搜索、定位、home等(可选)
    UIApplicationShortcutItemIcon File:使用项目中的图片作为标签图标 (可选)
    UIApplicationShortcutItemSubtitle:标签副标题 (可选)
    UIApplicationShortcutItemUserInfo:字典信息,如传值使用 (可选)

    纯代码方式实现3DTouch技术。

    // 自定义图标
    UIApplicationShortcutIcon *icon1 = [UIApplicationShortcutIcon iconWithTemplateImageName:@"pic1"];
    
    UIApplicationShortcutIcon *icon2 = [UIApplicationShortcutIcon iconWithTemplateImageName:@"pic2"];
    
    UIApplicationShortcutIcon *icon3 = [UIApplicationShortcutIcon iconWithTemplateImageName:@"pic3"];
    
    UIApplicationShortcutIcon *icon4 = [UIApplicationShortcutIcon iconWithTemplateImageName:@"pic4"];
        
    
    // 创建带着有自定义图标item
    UIMutableApplicationShortcutItem *item1 = [[UIMutableApplicationShortcutItem alloc]initWithType:@"pic1" localizedTitle:@"进入pic1" localizedSubtitle:@"自定义图标pic1" icon:icon1 userInfo:nil];
    
    UIMutableApplicationShortcutItem *item2 = [[UIMutableApplicationShortcutItem alloc]initWithType:@"pic2" localizedTitle:@"进入pic2" localizedSubtitle:@"自定义图标pic2" icon:icon2 userInfo:nil];
        
    UIMutableApplicationShortcutItem *item3 = [[UIMutableApplicationShortcutItem alloc]initWithType:@"pic3" localizedTitle:@"进入pic3" localizedSubtitle:@"自定义图标pic3" icon:icon3 userInfo:nil];
        
    UIMutableApplicationShortcutItem *item4 = [[UIMutableApplicationShortcutItem alloc]initWithType:@"pic4" localizedTitle:@"进入pic4" localizedSubtitle:@"自定义图标pic4" icon:icon4 userInfo:nil];
        
        
    [[UIApplication sharedApplication] setShortcutItems:@[item1,item2,item3,item4]];
    

    UIMutableApplicationShortcutItem初始化方法介绍如下:

    
    - (instancetype)initWithType:(NSString *)type 
                     localizedTitle:(NSString *)localizedTitle               
                     localizedSubtitle:(nullable NSString *)localizedSubtitle 
                     icon:(nullable UIApplicationShortcutIcon *)icon                 
                     userInfo:(nullable NSDictionary *)userInfo 
    
    • typeitem的唯一标识;
    • localizedTitle :是item的标题;
    • localizedSubtitleitem的副标题
    • iconitem icon设置的图片
    • userInfo :item所包含的信信息,类型是字典。
    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
        // Override point for customization after application launch.
        // 首先判断是否支持3DTouch
        if(self.window.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable)
        {
            // 创建3DTouch模型
        }
        return YES;
    }
    
    - (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
    {
        // 1.获得shortcutItem的type type就是初始化shortcutItem的时候传入的唯一标识符
        NSString *type = shortcutItem.type;
    
        //2.可以通过type来判断点击的是哪一个快捷按钮 并进行每个按钮相应的点击事件
        if ([type isEqualToString:@"pic1"]) {
            // do something
        }else if ([type isEqualToString:@"pic2"]){
            // do something
        }else if ([type isEqualToString:@"pic3"]){
            // do something
        }else if ([type isEqualToString:@"pic4"]){
            // do something
        } 
    }

    应用内的3DTouch技术的应用

    我们先控制器中在创建一个tableView,并遵守代理UIViewControllerPreviewingDelegate,再创建一个要跳转的目标控制器。代码如下:

    #import "ViewController.h"
    #import "HomeDetailController.h"
    @interface ViewController ()<UITableViewDelegate,UITableViewDataSource,UIViewControllerPreviewingDelegate>
    @property (nonatomic, strong) UITableView *tableView;
    @property (strong, nonatomic) NSMutableArray *datas;
    
    @end
    
    @implementation ViewController
    
    - (void)viewDidLoad {
        [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
        self.title = @"3DTouch_text";
        
        _datas = [[NSMutableArray alloc]init];
        for (NSInteger i = 0; i < 20; i++) {
            [_datas addObject:[NSString stringWithFormat:@"cell_%li",(long)I]];
        }
        
        self.tableView.frame = self.view.bounds;
        
        [self.view addSubview:self.tableView];
        [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"myCell"];
        
    }
    
    
    -(UITableView *)tableView{
        if (!_tableView) {
            _tableView = [[UITableView alloc]init];
            _tableView.delegate = self;
            _tableView.dataSource = self;
        }
        return _tableView;
    }
    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
        return _datas.count;
    }
    
    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"myCell"];
        if (cell == nil) {
            cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"myCell"];
        }
        cell.textLabel.text = _datas[indexPath.row];
        if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
            NSLog(@"3D Touch  可用!");
            //给cell注册3DTouch的peek(预览)和pop功能 ,注册(在哪个页面上使用该功能就注册在哪个页面上)
            [self registerForPreviewingWithDelegate:self sourceView:cell];
        } else {
            NSLog(@"3D Touch 无效");
        }
        return cell;
    }
    
    -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
        HomeDetailController *vc = [[HomeDetailController alloc]init];
        
        vc.name = [NSString stringWithFormat:@"%ld",(long)indexPath.row];
        
        [self.navigationController pushViewController:vc animated:YES];
    }
    
    //2.第二步
    #pragma mark - UIViewControllerPreviewingDelegate(实现代理的方法)
    - (UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location {
        
        HomeDetailController *vc = [[HomeDetailController alloc]init];
        
        //获取按压的cell所在行,[previewingContext sourceView]就是按压的那个视图
        NSIndexPath *indexPath = [self.tableView indexPathForCell:(UITableViewCell* )[previewingContext sourceView]];
        
        //设定预览的界面
        
        vc.preferredContentSize = CGSizeMake(0.0f,500.0f);
        vc.name = [NSString stringWithFormat:@"Cell_%ld,用力按进来,或者往上推",(long)indexPath.row];
        
        //调整不被虚化的范围,按压的那个cell不被虚化(轻轻按压时周边会被虚化,再少用力展示预览,再加力跳页至设定界面)
        CGRect rect = CGRectMake(0, 0, self.view.frame.size.width,40);
        previewingContext.sourceRect = rect;
        
        return vc;
        
    }
    
    - (void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit {
        [self.navigationController pushViewController:viewControllerToCommit animated:YES];
        
    }
    
    
    @end
    
    
    
    

    目标控制器中的代码实现:

    - (NSArray<id<UIPreviewActionItem>> *)previewActionItems {
        // setup a list of preview actions
        UIPreviewAction *action1 = [UIPreviewAction actionWithTitle:@"关注" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
            NSLog(@"关注");
        }];
        
        UIPreviewAction *action2 = [UIPreviewAction actionWithTitle:@"收藏" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
            NSLog(@"收藏");
        }];
        
        UIPreviewAction *action3 = [UIPreviewAction actionWithTitle:@"分享" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
            NSLog(@"分享");
        }];
        
        NSArray *actions = @[action1,action2,action3];
        
           return actions;
    }
    
    
    peek(预览) peek(预览)
