1 3D Touch 的三大模块

在我们的app中使用3D Touch功能，主要分一下三个模块:

1.1 Home Screen Quick Actions

通过主屏幕的应用Icon，我们可以用3D Touch 呼出一个菜单，进行快速定位应用功能模块相关功能的开发。

1.2 Peek and Pop

这个功能是一套全新的用户交互机制，在使用 3D Touch时，会有如下三个交互阶段:
(1) 轻按，提示用户这里有3D Touch 的交互，会使交互空间周围模糊

(2) 继续深按，会出现预览视图

（3）向上滑动预览视图通过视图上的交互控件进行进一步交互

 这个模块的设计可以在网址链接上进行网页的预览交互。

1.3 Force Properties

iOS9 为我们提供了新的交互参数:force 和 maximumPossibleForce 。

2 Home Screen Quick Actions 功能

应用最多有4个快捷选项标签，有两种方式开发 Home Screen Quick Actions 功能。

2.1 静态标签
打开项目的plist文件，添加如下项

选项介绍
UIApplicationShortcutItems : 数组中的元素就是我们的那些快捷选项标签.
UIApplicationShortcutItemType : 标签的唯一标示（必填）
UIApplicationShortcutItemTitle : 标签的标题（必填）
UIApplicationShortcutItemSubtitle : 标签的副标题（选填）
UIApplicationShortcutItemIconType : 标签的Icon类型（选填）
UIApplicationShortcutItemIconFile : 标签的Icon 文件,图标格式35x35像素单色 (选填)
UIApplicationShortcutItemUserInfo: 字典信息，传值使用(选填)

2.2 动态标签

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    self.window = [[UIWindow alloc] init];
    
    ViewController *mainView = [[ViewController alloc] init];
    UINavigationController *mainNav = [[UINavigationController alloc] initWithRootViewController:mainView];
    self.window.rootViewController = mainNav;
    [self.window makeKeyAndVisible];
    
    //动态创建应用图标上的3D touch快捷选项
    [self creatShortcutItem];
    
    UIApplicationShortcutItem *shortcutItem = [launchOptions valueForKey:UIApplicationLaunchOptionsShortcutItemKey];
    //如果是从快捷选项标签启动app，则根据不同标识执行不同操作，然后返回NO，防止调用- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler
    if (shortcutItem) {
        //判断先前我们设置的快捷选项标签唯一标识，根据不同标识执行不同操作
        if([shortcutItem.type isEqualToString:@"com.dimi.diandi86.main"]){
            
            DimiViewController *dimiVC = [[DimiViewController alloc] init];
            [self.window.rootViewController presentViewController:dimiVC animated:YES completion:^{
                
            }];
        } else if ([shortcutItem.type isEqualToString:@"com.dimi.diandi86.home"]) {
            DimiViewController *dimiVC = [[DimiViewController alloc] init];
            [self.window.rootViewController presentViewController:dimiVC animated:YES completion:^{
                
            }];
        } else if ([shortcutItem.type isEqualToString:@"com.dimi.diandi86.wonderful"]) {
            DimiViewController *dimiVC = [[DimiViewController alloc] init];
            [self.window.rootViewController presentViewController:dimiVC animated:YES completion:^{
                
            }];
        }
        return NO;
    }
    
    return YES;
}

- (void)creatShortcutItem
{
    //创建系统风格的icon
    UIApplicationShortcutIcon *icon = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];
    
    //    //创建自定义图标的icon,图标格式35x35像素单色
    //UIApplicationShortcutIcon *icon = [UIApplicationShortcutIcon iconWithTemplateImageName:@"Wonderful.png"];
    
    //创建快捷选项
    UIApplicationShortcutItem * item = [[UIApplicationShortcutItem alloc] initWithType:@"com.dimi.diandi86.wonderful" localizedTitle:@"精彩" localizedSubtitle:nil icon:icon userInfo:nil];
    
    //添加到快捷选项数组
    [UIApplication sharedApplication].shortcutItems = @[item];
}

效果图如下:

2.3 点击快捷选项标签进入应用的响应

//如果app在后台，通过快捷选项标签进入app，则调用该方法，如果app不在后台已杀死，则处理通过快捷选项标签进入app的逻辑在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void(^)(BOOL succeeded))completionHandler
{
    //判断先前我们设置的快捷选项标签唯一标识，根据不同标识执行不同操作
    if (shortcutItem) {
        //判断先前我们设置的快捷选项标签唯一标识，根据不同标识执行不同操作
        if([shortcutItem.type isEqualToString:@"com.dimi.diandi86.main"]){
            DimiViewController *dimiVC = [[DimiViewController alloc] init];
            [self.window.rootViewController presentViewController:dimiVC animated:YES completion:^{
                
            }];
        } else if ([shortcutItem.type isEqualToString:@"com.dimi.diandi86.home"]) {
            DimiViewController *dimiVC = [[DimiViewController alloc] init];
            [self.window.rootViewController presentViewController:dimiVC animated:YES completion:^{
                
            }];
        } else if ([shortcutItem.type isEqualToString:@"com.dimi.diandi86.wonderful"]) {
            DimiViewController *dimiVC = [[DimiViewController alloc] init];
            [self.window.rootViewController presentViewController:dimiVC animated:YES completion:^{
                
            }];
        }
    }
    
    if (completionHandler) {
        completionHandler(YES);
    }
}

效果图如下

3 Peek and Pop 功能

应用启动之后界面如下

3D Touch主界面.png

3.1 让ViewController 遵守UIViewControllerPreviewingDelegate协议

@interface ViewController ()

@property (nonatomic, strong) UITableView *mainTableView;

@property (nonatomic, strong) NSMutableArray *dataArray;

@end

3.2 给 cell 注册 3D Touch 的 Peek and Pop 功能

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *identifier = @"cellIdentifier";
    UITableViewCell * cell = nil;
    cell = [tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
    }
    
    cell.textLabel.text = [self.dataArray objectAtIndex: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
        [self registerForPreviewingWithDelegate:self sourceView:cell];
    } else {
        NSLog(@"3D Touch 无效");
    }
    
    return cell;
}

3.3 实现 UIViewControllerPreviewingDelegate 方法

#pragma mark - UIViewControllerPreviewingDelegate method
//peek(预览模式)
- (nullable UIViewController *)previewingContext:(id )previewingContext viewControllerForLocation:(CGPoint)location
{
    //获取按压的cell所在行，[previewingContext sourceView]就是按压的那个视图
    NSIndexPath *indexPath = [self.mainTableView indexPathForCell:(UITableViewCell* )[previewingContext sourceView]];
    
    //设定预览的界面
    DimiViewController *childVC = [[DimiViewController alloc] init];
    childVC.preferredContentSize = CGSizeMake(0.0f,500.0f);
    
    //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;
    
    //返回预览界面
    return childVC;
}

//pop（继续按压进入）
- (void)previewingContext:(id )previewingContext commitViewController:(UIViewController *)viewControllerToCommit
{
    DimiViewController *childVC = [[DimiViewController alloc] init];
    
    [self.navigationController pushViewController:childVC animated:YES];
}

预览界面效果图如下

3.4 预览界面向上滑动交互实现，在DimiViewController 中实现previewActionItems方法

- (NSArray> *)previewActionItems
{
    // setup a list of preview actions
    UIPreviewAction *action1 = [UIPreviewAction actionWithTitle:@"Aciton1" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
        NSLog(@"Aciton1");
    }];
    
    UIPreviewAction *action2 = [UIPreviewAction actionWithTitle:@"Aciton2" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
        NSLog(@"Aciton2");
    }];
    
    NSArray *actions = @[action1,action2];
    
    return actions;
}

效果图如下

4 Force Properties 的运用

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSArray *arrayTouch = [touches allObjects];
    UITouch *touch = (UITouch *)[arrayTouch lastObject];
    //通过tag确定按压的是哪个view，注意：如果按压的是label，将label的userInteractionEnabled属性设置为YES
    if (touch.view.tag == 520) {
        self.touchTipValueLabel.text = [NSString stringWithFormat:@"压力值:%f",touch.force];
    }
}

#pragma mark - getter and setter
- (UILabel*)touchLabel
{
    if (_touchLabel == nil) {
        _touchLabel = [[UILabel alloc] init];
        _touchLabel.font = [UIFont systemFontOfSize:25];
        _touchLabel.text = @"按下我";
        _touchLabel.userInteractionEnabled = YES;
        _touchLabel.textAlignment = NSTextAlignmentCenter;
        _touchLabel.tag = 520;
    }
    
    return _touchLabel;
}

- (UILabel*)touchTipValueLabel
{
    if (_touchTipValueLabel == nil) {
        _touchTipValueLabel = [[UILabel alloc] init];
        _touchTipValueLabel.font = [UIFont systemFontOfSize:25];
        _touchTipValueLabel.text = @"压力值:";
        _touchTipValueLabel.textAlignment = NSTextAlignmentCenter;
    }
    
    return _touchTipValueLabel;
}

效果图如下
