3DTouch简单了解
3D Touch的三大模块
代码Demo:https://github.com/haozheMa/3DTouch
在我们的app中使用3D Touch功能,主要分为以下三个模块:
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。如上面的日历。
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,ViewController中会有如下三个交互阶段:
(1)提示用户这里有3D Touch的交互,会使交互控件周围模糊
(2)继续深按,会出现预览视图
(3)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连接上进行网页的预览交互。
3.Force Properties
iOS9为我们提供了一个新的交互参数:力度。我们可以检测某一交互的力度值,来做相应的交互处理。例如,我们可以通过力度来控制快进的快慢,音量增加的快慢等。
Home Screen Quick Action使用与相关api详解
1、静态标签
静态标签是我们在项目的配置plist文件中配置的标签,在用户安装程序后就可以使用,并且排序会在动态标签的前面。
我们先来看静态标签的配置:
首先,在info.plist文件中添加如下键值(我在测试的时候,系统并没有提示,只能手打上去):
先添加了一个UIApplicationShortcutItems的数组,这个数组中添加的元素就是对应的静态标签,在每个标签中我们需要添加一些设置的键值:
必填项(下面两个键值是必须设置的):
UIApplicationShortcutItemType 这个键值设置一个快捷通道类型的字符串
UIApplicationShortcutItemTitle 这个键值设置标签的标题
选填项(下面这些键值不是必须设置的):
UIApplicationShortcutItemSubtitle 设置标签的副标题
UIApplicationShortcutItemIconType 设置标签Icon类型
UIApplicationShortcutItemIconFile 设置标签的Icon文件
UIApplicationShortcutItemUserInfo 设置信息字典(用于传值)
把截图中的内容配置一下,就可以运行程序,测试一下
2、动态标签
动态标签是我们在程序中,通过代码添加的,与之相关的类,主要有三个:
UIApplicationShortcutItem 创建3DTouch标签的类
UIMutableApplicationShortcutItem 创建可变的3DTouch标签的类
UIApplicationShortcutIcon 创建标签中图片Icon的类
首先介绍3DTouch的属性和方法
@interface UIApplicationShortcutItem : NSObject <NSCopying, NSMutableCopying> //下面是两个初始化方法 通过设置type,title等属性来创建一个标签,这里的icon是UIApplicationShortcutIcon对象,我们后面再说 - (instancetype)initWithType:(NSString *)type localizedTitle:(NSString *)localizedTitle localizedSubtitle:(nullable NSString *)localizedSubtitle icon:(nullable UIApplicationShortcutIcon *)icon userInfo:(nullable NSDictionary *)userInfo NS_DESIGNATED_INITIALIZER; - (instancetype)initWithType:(NSString *)type localizedTitle:(NSString *)localizedTitle; //下面这是一些只读的属性,获取相应的属性值 @property (nonatomic, copy, readonly) NSString *type; @property (nonatomic, copy, readonly) NSString *localizedTitle; @property (nullable, nonatomic, copy, readonly) NSString *localizedSubtitle; @property (nullable, nonatomic, copy, readonly) UIApplicationShortcutIcon *icon; @property (nullable, nonatomic, copy, readonly) NSDictionary<NSString *, id <NSSecureCoding>> *userInfo;
//这个类继承于 UIApplicationShortcutItem,创建的标签可变 @interface UIMutableApplicationShortcutItem : UIApplicationShortcutItem @property (nonatomic, copy) NSString *type; @property (nonatomic, copy) NSString *localizedTitle; @property (nullable, nonatomic, copy) NSString *localizedSubtitle; @property (nullable, nonatomic, copy) UIApplicationShortcutIcon *icon; @property (nullable, nonatomic, copy) NSDictionary<NSString *, id <NSSecureCoding>> *userInfo; @end
//这个类创建标签中的icon @interface UIApplicationShortcutIcon : NSObject <NSCopying> //创建系统风格的icon + (instancetype)iconWithType:(UIApplicationShortcutIconType)type; //创建自定义的图片icon + (instancetype)iconWithTemplateImageName:(NSString *)templateImageName; @end
下边是实现的代码,可以写在RootVC中,也可以写在AppDlegate的
didFinishLaunchingWithOptions方法中(根据所查网络资料,写这两处都好使)
- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. //创建 UIApplicationShortcutItem * item = [[UIApplicationShortcutItem alloc]initWithType:@"2" localizedTitle:@"按钮标签" localizedSubtitle:@"副标题" icon:[UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypePlay] userInfo:nil]; 添加 [UIApplication sharedApplication].shortcutItems = @[item]; }
图标枚举类型
typedef NS_ENUM(NSInteger, UIApplicationShortcutIconType) { UIApplicationShortcutIconTypeCompose,//编辑的图标 UIApplicationShortcutIconTypePlay,//播放图标 UIApplicationShortcutIconTypePause,//暂停图标 UIApplicationShortcutIconTypeAdd,//添加图标 UIApplicationShortcutIconTypeLocation,//定位图标 UIApplicationShortcutIconTypeSearch,//搜索图标 UIApplicationShortcutIconTypeShare//分享图标 } NS_ENUM_AVAILABLE_IOS(9_0);
3、响应标签的行为
我们在AppDlegate中添加方法
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void(^)(BOOL succeeded))completionHandler{ }
使用的话可以类似这样
/** 处理shortcutItem */ - (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void (^)(BOOL))completionHandler { switch (shortcutItem.type.integerValue) { case 1: { // 测试1 [[NSNotificationCenter defaultCenter] postNotificationName:@"gotoTestVc" object:self userInfo:@{@"type":@"1"}]; } case 2: { // 测试2 [[NSNotificationCenter defaultCenter] postNotificationName:@"gotoTestVc" object:self userInfo:@{@"type":@"2"}]; } break; default: break; } }
或者这样
- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void(^)(BOOL succeeded))completionHandler{ //判断先前我们设置的唯一标识 if([shortcutItem.type isEqualToString:@"-11.UITouchText.share"]){ NSArray *arr = @[@"hello 3D Touch"]; UIActivityViewController *vc = [[UIActivityViewController alloc]initWithActivityItems:arr applicationActivities:nil]; //设置当前的VC 为rootVC [self.window.rootViewController presentViewController:vc animated:YES completion:^{ }]; } }
几点注意:
1、快捷标签最多可以创建四个,包括静态的和动态的。
2、每个标签的题目和icon最多两行,多出的会用...省略
感觉差不多是这个样子吧。

peek and pop
实现peek和pop手势:
1、遵守协议 UIViewControllerPreviewingDelegate
2、注册 [self registerForPreviewingWithDelegate:self sourceView:self.view];
3、实现代理方法
具体代码:(与Home Screen Quick Action相互独立)
先写主页面的内容RootView
#import "ViewController.h" #import "DetailViewController.h" #define _ScreenWidth [UIScreen mainScreen].bounds.size.width #define _ScreenHeight [UIScreen mainScreen].bounds.size.height @interface ViewController ()<UITableViewDelegate,UITableViewDataSource,UIViewControllerPreviewingDelegate> @property (strong,nonatomic) UITableView *tableView; @property (copy, nonatomic) NSArray *items; @property (assign, nonatomic) CGRect sourceRect; //用户手势点 @property (strong, nonatomic) NSIndexPath *indexPath; //用户手势点 @end @implementation ViewController /* 实现peek和pop手势: 1、遵守协议 UIViewControllerPreviewingDelegate 2、注册 [self registerForPreviewingWithDelegate:self sourceView:self.view]; 3、实现代理方法 */ - (void)viewDidLoad { [super viewDidLoad]; [self loadTableview]; //注册Peek和Pop if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) { /** * 这个判断的作用是检测当前设备是否支持 3D Touch */ [self registerForPreviewingWithDelegate:self sourceView:self.view]; } } //加载tableview -(void)loadTableview { self.tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, _ScreenWidth, _ScreenHeight) style:UITableViewStylePlain]; self.tableView.rowHeight = 50; self.tableView.delegate= self; self.tableView.dataSource = self; [self.view addSubview:self.tableView]; } -(NSArray *)items { if (_items == nil) { _items = [[NSArray alloc]initWithObjects:@"第一条",@"第二条",@"第三条",@"第四条",@"第五条",@"第六条",nil]; } return _items; } #pragma mark - tableViewDelage -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return self.items.count; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellID = @"cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID]; } cell.textLabel.text = self.items[indexPath.row]; return cell; } -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"点击了/pop第%zdcell",indexPath.row+1); } #pragma mark - peek&& pop代理 /** peek手势 */ -(nullable UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location { //获取用户手势点的Cell的下标,同时判断手势点是否超出tableview的响应范围 if (![self getShouldShowRectAndIndexPathWithLocation:location]) return nil; previewingContext.sourceRect = self.sourceRect; NSIndexPath *index = [_tableView indexPathForRowAtPoint:location]; UITableViewCell *cell = [_tableView cellForRowAtIndexPath:index]; if(cell != nil ){ DetailViewController *detailViewController = [[DetailViewController alloc] init]; detailViewController.text = [NSString stringWithFormat:@"点击了第%zd个cell,预览图层,再用力按调用pop手势的代理方法", index.row+1]; return detailViewController; } return nil; } /** pop手势 */ - (void)previewingContext:(id <UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit { // [self tableView:self.tableView didSelectRowAtIndexPath:self.indexPath]; [self showViewController:viewControllerToCommit sender:self]; } /** 获取用户手势点所在cell的下标。同时判断手势点是否超出tableView响应范围。*/ -(BOOL)getShouldShowRectAndIndexPathWithLocation:(CGPoint)location { NSInteger row = (location.y - 20)/50; self.sourceRect = CGRectMake(0, row * 50 , _ScreenWidth, 50); self.indexPath = [NSIndexPath indexPathForItem:row inSection:0]; // 如果row越界了,返回NO 不处理peek手势 return row >= self.items.count ? NO : YES; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end
然后是预览的那个DetailVC
// // DetailViewController.h // 3DTouchPreviewDemo // // Created by apple on 16/4/14. // Copyright © 2016年 apple. All rights reserved. // #import <UIKit/UIKit.h> @interface DetailViewController : UIViewController @property (nonatomic, strong) NSString *text; @end
// // DetailViewController.m // 3DTouchPreviewDemo // // Created by apple on 16/4/14. // Copyright © 2016年 apple. All rights reserved. // #import "DetailViewController.h" @interface DetailViewController () @end @implementation DetailViewController - (void)viewDidLoad { [super viewDidLoad]; UIView *bgView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)]; bgView.backgroundColor = [UIColor whiteColor]; [self.view addSubview:bgView]; UIButton *btn = [[UIButton alloc]initWithFrame:CGRectMake(20, 64, 50, 50)]; btn.backgroundColor = [UIColor redColor]; [btn setTitle:@"返回" forState:UIControlStateNormal]; [btn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal]; [btn addTarget:self action:@selector(getHome) forControlEvents:UIControlEventTouchUpInside]; [bgView addSubview:btn]; UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 120, self.view.frame.size.width, self.view.frame.size.height)]; textView.font = [UIFont systemFontOfSize:24]; textView.text = self.text; [bgView addSubview:textView]; } -(void)getHome { [self dismissViewControllerAnimated:YES completion:nil]; } - (NSArray<id<UIPreviewActionItem>> *)previewActionItems { UIPreviewAction *itemShare = [UIPreviewAction actionWithTitle:@"分享" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"分享" message:@"分享内容" delegate:nil cancelButtonTitle:@"确定" otherButtonTitles: nil]; [alertView show]; }]; return @[itemShare]; } @end
运行结果:
