ios 3D Touch功能的实现

ios9中3D Touch功能是一个新的亮点,这个方便快捷的功能实现也比较简单,废话不多说直接上代码,

一.3D Touch功能添加分为两种(1).静态标签 (2).动态标签

(1).静态添加

这个方法是在app的plist文件中添加如下图的键值对,

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)

(2).动态标签

动态标签是我们在程序运行过程中动态添加上去的,可以修改或者直接取消,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

 @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;

接下来就是创建标签

 /**
  *  手动添加3D touch功能
  */
 -(void)init3DTouchActionShow:(BOOL)isShow{
     
     /** type 该item 唯一标识符
      localizedTitle :标题
      localizedSubtitle:副标题
      icon:icon图标 可以使用系统类型 也可以使用自定义的图片
      userInfo:用户信息字典 自定义参数,完成具体功能需求
      */
     
     UIApplication *application = [UIApplication sharedApplication];
     UIApplicationShortcutIcon *icon1 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeLove];
     UIApplicationShortcutItem *item1 = [[UIApplicationShortcutItem alloc]initWithType:KTouchItemPublicPosition localizedTitle:@"我就是我" localizedSubtitle:@"还有什么" icon:icon1 userInfo:nil];
    
    UIApplicationShortcutIcon *icon2 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeShare];
     UIApplicationShortcutItem *item2 = [[UIApplicationShortcutItem alloc]initWithType:KTouchItemMyPublic localizedTitle:@"你就是你" localizedSubtitle:@"你知道" icon:icon2 userInfo:nil];
     
     UIApplicationShortcutIcon *icon3 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeCompose];
     UIApplicationShortcutItem *item3 = [[UIApplicationShortcutItem alloc]initWithType:KTouchItemRecharge localizedTitle:@"他就是他" localizedSubtitle:@"我不知道" icon:icon3 userInfo:nil];
     
     UIApplicationShortcutIcon *icon4 = [UIApplicationShortcutIcon iconWithType:UIApplicationShortcutIconTypeCompose];
     UIApplicationShortcutItem *item4 = [[UIApplicationShortcutItem alloc]initWithType:KTouchItemCheck localizedTitle:@"她就是她" localizedSubtitle:@"不信算了" icon:icon4 userInfo:nil];
     if (isShow) {
         application.shortcutItems = @[item1,item2,item3,item4];
    }else{
         application.shortcutItems = @[];
     }
 }

动态方法添加可以在某个条件下取消3D Touch功能,比如登陆之前取消3D Touch功能和登陆之后添加3D Touch功能,代码中的UIApplicationShortcutIconTypeShare等是系统风格的icon,这里只是举个例子直接拿来用,但是不知道审核的时候会不会被拒。

typedef NS_ENUM(NSInteger, UIApplicationShortcutIconType) {
    UIApplicationShortcutIconTypeCompose,
    UIApplicationShortcutIconTypePlay,
    UIApplicationShortcutIconTypePause,
    UIApplicationShortcutIconTypeAdd,
    UIApplicationShortcutIconTypeLocation,
    UIApplicationShortcutIconTypeSearch,
    UIApplicationShortcutIconTypeShare,
    UIApplicationShortcutIconTypeProhibit       NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeContact        NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeHome           NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeMarkLocation   NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeFavorite       NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeLove           NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeCloud          NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeInvitation     NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeConfirmation   NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeMail           NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeMessage        NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeDate           NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeTime           NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeCapturePhoto   NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeCaptureVideo   NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeTask           NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeTaskCompleted  NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeAlarm          NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeBookmark       NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeShuffle        NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeAudio          NS_ENUM_AVAILABLE_IOS(9_1),
    UIApplicationShortcutIconTypeUpdate         NS_ENUM_AVAILABLE_IOS(9_1)
} NS_ENUM_AVAILABLE_IOS(9_0) __TVOS_PROHIBITED;

这里有几点需要注意:

1、快捷标签最多可以创建四个,包括静态的和动态的,静态标签会一直存在。

2、每个标签的题目和icon最多两行,多出的会用...省略

3、我们在app的入口函数:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions;

也需要进行一下判断,在launchOptions中有UIApplicationLaunchOptionsShortcutItemKey这样一个键,通过它,我们可以区别是否是从标签进入的app,如果是则处理结束逻辑后,返回NO,防止处理逻辑被反复回调。

二.响应标签的行为

当我们点击标签进入应用程序时,也可以进行一些操作,我们可以看到,在applocation中增加了这样一个方法:

- (void)application:(UIApplication *)application performActionForShortcutItem:(UIApplicationShortcutItem *)shortcutItem completionHandler:(void(^)(BOOL succeeded))completionHandler NS_AVAILABLE_IOS(9_0);(要注意上面的第三点)

当我们通过标签进入app时,就会在appdelegate中调用这样一个回调,我们可以获取shortcutItem的信息进行相关逻辑操作。

 #pragma mark -3Dtouch功能
 - (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
     NSLog(@"选择了3Dtouch功能--%@",shortcutItem.type);
     UIViewController *myVC;
     if ([shortcutItem.type isEqualToString:KTouchItemPublicPosition]) {
         myVC = [[YBSPublicViewController alloc]initWithNibName:@"YBSPublicViewController" bundle:nil];
    }else if ([shortcutItem.type isEqualToString:KTouchItemMyPublic]){
         myVC = [[YBSPositionViewController alloc]initWithNibName:@"YBSPositionViewController" bundle:nil];
     }else if ([shortcutItem.type isEqualToString:KTouchItemRecharge]){
         myVC = [[YBSResumeViewController alloc]initWithNibName:@"YBSResumeViewController" bundle:nil];
     }else if ([shortcutItem.type isEqualToString:KTouchItemCheck]){
         myVC = [[YBSResumeViewController alloc]initWithNibName:@"YBSResumeViewController" bundle:nil];
     }
     YBSNavigationViewController *nav = [[YBSNavigationViewController alloc]initWithRootViewController:myVC];
     //设置当前的VC 为rootVC
     [self.window.rootViewController presentViewController:nav animated:YES completion:nil];
    
 }
这里面主要是做一个例子,显示的视图跳转 要根据具体情况加上

效果图

三. 3D Touch ViewController  弹出自定义的ViewContoller,向上滑动还有下一步的菜单可以显示

首先在viewController的.m方法中添加下面代码,判断当前设备是否支持压力感,并注册delegate

//注册3D Touch,先判断是否可用
    if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable){
         [self registerForPreviewingWithDelegate:self sourceView:self.view];
         NSLog(@"3D Touch  可用!");
    }else{
         NSLog(@"3D Touch 无效");
    }

添加你想要弹出来的viewcontroller,

/**
 *  peek手势
 */
-(UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location{
    
     // 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。
     if (![self getShouldShowRectAndIndexPathWithLocation:location]) return nil;
     //弹出视图的初始位置,sourceRect是peek触发时的高亮区域。这个区域内的View会高亮显示,其余的会模糊掉
     previewingContext.sourceRect = sourceRect;
    //获取数据进行传值
    YBS3DTouchViewController *childVC = [[YBS3DTouchViewController alloc] init];
     return childVC;
}

/**
 *  pop手势
 */
-(void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit{
     [self tableView:self.myTableView didSelectRowAtIndexPath:selectedPath];
}

/**
 *  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的范围
 */
- (BOOL)getShouldShowRectAndIndexPathWithLocation:(CGPoint)location {
    //坐标点的转化,
    CGPoint tableLocation = [self.view convertPoint:location toView:self.myTableView];
    selectedPath = [self.myTableView indexPathForRowAtPoint:tableLocation];
    sourceRect = CGRectMake(0, selectedPath.row * KMessageRowHeight, ScreenHeight, KMessageRowHeight);
     // 如果row越界了,返回NO 不处理peek手势
    NSLog(@"当前所在的行---%zd",selectedPath.row);
     return (selectedPath.row >= (self.messageArr.count+10)) ? NO : YES;
 }

接下来在添加的视图中,添加向上滑显示的菜单,上面代码中YBS3DTouchViewController *childVC,视图中我就是简单定义了一个backView和一个label,下面是在-(NSArray<id<UIPreviewActionItem>> *)previewActionItems函数中定义你要显示的菜单

/**
 *  3D Touch 上移显示的视图
 */
-(NSArray<id<UIPreviewActionItem>> *)previewActionItems{
    UIPreviewAction *action1 = [UIPreviewAction actionWithTitle:@"我就是我" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
        NSLog(@"click---我就是我");
        
    }];
    
    UIPreviewAction *action2 = [UIPreviewAction actionWithTitle:@"你还是你" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
        NSLog(@"click---你还是你");
    }];
    
    UIPreviewAction *action3 = [UIPreviewAction actionWithTitle:@"她还是她" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
        NSLog(@"click---她还是她");
    }];
    //想要显示多个就定义多个 UIPreviewAction
    NSArray *actions = @[action1,action2,action3];
    return actions;
}

在block里面进行的一个回调,在这里处理你的点击事件,效果如下

学习的就这么多,有更多的,后面加上😊
