一种列表显示方法、装置、设备及存储介质
相关申请的交叉引用
本申请要求2018年12月14日在中国知识产权局提交的中国专利申请No.201811533884.1的优先权，通过引用将该中国专利申请公开的全部内容并入本文。
技术领域
本公开涉及应用程序开发技术领域，尤其涉及一种列表显示方法、装置、设备及存储介质。
背景技术
在开发基于iOS操作系统的移动应用程序时，开发者经常使用列表方式来展示应用内容。iOS系统为开发者提供了三种列表，分别为UITableView、UICollectionView和UIScrollView，其中，前两种列表是基于第三种列表实现的，UITableView是纵向可滑动列表，UICollectionView的滑动方向可在横向和纵向二者间进行选择，而UIScrollView在横向和纵向上均可滑动。在应用程序开发过程中，开发者往往选择UITableView和UICollectView，以使开发更加便捷。UITableView和UICollectView的创建开发阶段基本一致，可以概括如下：
步骤1、使用原生语言定义各种类型的列表单元格(Cell)类型，复杂列表里的单元格(Cell)类型多至20多种；
步骤2、对步骤1中各种单元格(Cell)类型的子视图进行布局；
步骤3、为步骤1中各种单元格(Cell)类型添加数据处理逻辑；
步骤4、为步骤1中各种单元格(Cell)类型添加事件处理逻辑；
步骤5、创建列表实例，设置列表属性，如背景颜色、布局类型、滑动方向等；
步骤6、向列表实例注册步骤1定义的所有单元格(Cell)类型；
步骤7、实现列表实例的数据源代理和事件回调代理；
步骤8、完成列表的创建。
从列表的创建步骤可以看出：列表单元格(Cell)类型的定义须先行于列表的创建，也就是说列表单元格(Cell)类型和列表的创建强相关，在多业务团队协作开发环境下，列表的业务可能由多个业务团队共同完成，团队业务进度的不同将导致团队互相依赖，不利于业务协同推进，同时也不利于动态的插入新的单元格(Cell)样式，从而不能满足需要灵活配置的业务需求；另外，在一个业务稍微复杂些的列表中，往往需要定义多种列表单元格(Cell)，并且列表单元格(Cell)的定义过程复杂，类型增多时也会增加重复操作，比如列表单元格(Cell)子视图的创建、子视图布局、数据处理和事件处理等，这大大降低了开发效率。
在创建列表后，客户端按照固化在代码中单元格类型的定义数据生成单元格实例，并进行渲染显示，显示效果单一，缺乏灵活性。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，以下将参照本公开实施例中的附图，通过实施方式清楚、完整地描述本公开的技术方案，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
下述各实施例中，每个实施例中同时提供了可选特征和示例，实施例中记载的各个特征可进行组合，形成多个可选方案，不应将每个编号的实施例仅视为一个技术方案。
实施例一
图1示出了根据本公开实施例的一种列表显示方法的流程图，本公开实施例可适用于在基于iOS系统的应用程序中显示列表的情况，该方法可以由列表显示装置来执行，该装置可以由软件和/或硬件的方式来实现，集成于具有显示功能的终端中，如智能手机、平板电脑等。
如图1所示，本公开实施例中提供的列表显示方法具体包括以下步骤：
S110、根据待显示的列表实例中的数据源信息，获取列表实例的待显示单元格对应的待显示数据和单元格类型。
其中，列表实例可以是指预先创建开发的一个列表。列表实例中的数据源信息可以是指列表实例所使用的数据库或数据库服务器的信息，可以包括但不限于数据源名称。列表实例中可以包括一个或多个待显示单元格，待显示单元格的数量可以根据业务需求预先确定。本实施例可以为每个单元格类型设置一个标识符进行唯一标识，以便于区分不同的单元格类型。
具体地，本实施例可以根据列表实例中的数据源信息，与列表实例对应的列表数据库进行连接，从而可以从列表数据库中获得待显示的列表实例中每个待显示单元格对应的待显示数据以及对应的单元格类型。
S120、加载并解析预先生成的至少一个采用结构化语言的单元格描述文件，其中各单元格描述文件中存储有至少一种单元格类型对应的元数据，元数据包括子视图层级结构信息和属性设置信息。
其中，结构化语言可以为但不限于JavaScript对象标记JSON(JavaScript Object Notation)语言或可扩展标记语言XML(Extensible Markup Language)。列表对应的所有单元格类型的元数据可以只存储到一个单元格描述文件中，也可以分散存储到多个单元格描述文件中，以便在多业务团队协作情况下，不同业务团队可以提供自己的单元格描述文件，使得不同业务可以并行推进。每个单元格描述文件可以存储一种或多种单元格类型对应的元数据。子视图层级结构信息可以是指单元格包含的多个子视图之间的层级关系信息。属性设置信息可以包括但不限于颜色、字体、字号和字形。
具体地，本实施例可以预先采用结构化语言描述每种单元格类型对应的 元数据，并将描述的所有单元格类型对应的元数据存储到一个或多个单元格描述文件中，从而可以对单元格类型定义和列表创建进行解耦，以使单元格类型可以滞后加载和注册。本实施例可以在获取列表实例的待显示单元格对应的待显示数据和单元格类型之后，通过列表实例加载并解析至少一个单元格描述文件，从而可以动态获得每个单元格类型对应的元数据。示例性地，本实施例在采用结构化语言定义单元格类型时，可以为每个单元格类型分配一个全局的唯一标识符，以便于从单元格描述文件中查询单元格类型对应的元数据。
需要注意的是，当根据业务需求需要修改列表显示效果时，可以采用结构化语言描述新的单元格类型对应的元数据，并将描述后的元数据添加至单元格描述文件中，以更新单元格描述文件，从而在对列表进行显示时，可以通过加载并解析更新后的单元格描述文件，获得新的单元格类型对应的元数据，以使在列表的运行阶段，可以对列表进行动态灵活地配置，提高了列表配置的灵活性。
S130、根据待显示单元格对应的单元格类型的元数据，创建单元格实例。
可选地，根据待显示数据对单元格实例进行渲染和显示。
具体地，可以通过待显示单元对应的单元格类型的唯一标识符，从解析后的单元格描述文件中获得待显示单元格对应的单元格类型的元数据。根据元数据中的子视图层级结构信息可以建立待显示单元格子视图间的父子关系，从而形成待显示单元格的子视图层级树，并根据解析后的属性设置信息和子视图层级树可以创建单元格实例。在待显示单元格对应的单元格实例创建后，可以根据待显示单元格对应的待显示数据对单元格实例进行渲染，以便在显示界面中可以展示渲染后的单元格。同理，对于列表实例中的每个待显示单元格而言，均可以通过执行步骤S130的操作，渲染和显示列表实例中的每个待显示单元格，从而实现了列表的显示。
本公开实施例的技术方案，通过预先采用结构化语言定义单元格类型，形成单元格描述文件，而非使用原生语言，使得单元格类型可以滞后加载和注册，从而在运行过程中，当获取列表实例中的待显示单元对应的待显示数据后，可以通过加载并解析单元格描述文件的方式，获得待显示单元对应的 单元格类型的元数据，并且可以通过在单元格描述文件中添加新的单元格类型的方式，对列表进行动态灵活地配置，从而可以根据业务需求进行显示，提高了列表配置的灵活性，以及实现了列表显示的多样性。
在上述技术方案的基础上，在S130中根据待显示单元格对应的单元格类型的元数据，创建单元格实例之后，还可以包括：
若单元格实例被释放，则回收该单元格实例，缓存该单元格实例以及该单元格实例对应的单元格类型，以使后续需要对相同类型的单元格进行显示时，读取缓存的单元格实例并对读取的单元格实例进行渲染和显示。
具体地，当单元格实例使用完后被列表释放时，可以回收单元格实例，并将单元格实例以及单元格实例对应的单元格类型进行缓存，以便后续在需要显示相同类型的单元格时，可以直接读取缓存的单元格实例，无需重新创建该单元格类型的单元格实例，从而可以减少单元格的创建时间，提高列表的滑动性能。
示例性地，在根据待显示单元格对应的单元格类型的元数据，创建单元格实例之前，可以检测缓存中是否存在待显示单元格的单元格类型对应的闲置的单元格实例，若存在，则直接读取该单元格实例；若不存在，则从解析后的单元格描述文件中获取待显示单元格对应的单元格类型的元数据，根据获得的元数据创建单元格实例，并将创建的单元格实例和对应的单元格类型进行缓存，以避免后续重复创建该单元格实例。本实施例通过设置单元格实例的缓存机制，可以提高单元格实例的复用度以及创建速度，从而提高了列表的滑动性能。
在上述技术方案的基础上，S130中根据待显示数据对单元格实例进行渲染和显示，可以包括：确定单元格实例中各子视图的布局参数，其中布局参数包括子视图的尺寸参数和子视图在单元格中的位置参数；根据布局参数和待显示数据对单元格实例进行渲染和显示，并缓存布局参数，以使后续使用缓存的布局参数对相同类型的单元格实例进行渲染。
其中，子视图的尺寸参数可以包括但不限于子视图的高度和宽度。子视图在单元格中的位置参数可以是指子视图在显示界面上的显示位置信息。具体地，本实施例可以根据列表实例中的数据源信息，在与列表实例对应的列 表数据库中，获取预先设置的每个子视图的视图尺寸以及子视图与父视图的相对位置关系，从而可以根据子视图的视图尺寸和显示界面的界面尺寸，计算得到每个子视图在显示界面中显示的尺寸参数，以及根据子视图和父视图的相对位置关系计算得到每个子视图在单元格中的位置参数。本实施例可以缓存待显示单元格对应的单元格实例中的每个子视图的布局参数，以便后续在需要显渲染相同单元格类型对应的单元格实例时，可以直接使用缓存的单元格实例对应的布局参数，无需重复确定该单元格实例对应的布局参数，从而通过缓存单元格实例对应的布局参数可以进一步提高列表的滑动性能。
在上述技术方案的基础上，在S130中创建单元格实例之后，方法还包括：为单元格实例的子视图添加触控行为处理函数；相应地，在S130之后还可以包括：通过触控行为处理函数检测针对显示的子视图的触控操作，并在检测到触控操作后，将触控操作的信息作为输入参数，调用预先针对列表实例设置的事件处理对象，以对触控操作进行处理。
其中，触控行为处理函数可以是预先定义的，用于检测是否存在触控操作的函数。触控操作可以是但不限于触摸行为或者点击行为。事件处理对象可以是预先设置的，用于对列表实例中子视图中控件的触控操作进行逻辑处理。
具体地，开发者可以根据业务需求预先设置单元格实例中的子视图是否接受用户的触控操作，并将指定的需要接收用户触控操作的子视图信息存储至单元格描述文件中。在创建单元格实例后，可以根据单元格描述文件中需要接受用户触控操作的指定子视图信息，为单元格实例中每个指定子视图添加一个触控行为处理函数，从而可以自动开启单元格实例中指定子视图的触控操作，使得操作更加便捷。
在列表显示后，可以通过触控行为处理函数检测是否对指定的子视图进行触控操作，若检测到触控操作时，可以通过调用事件处理对象，将检测到的触控操作通过唯一的事件出口传递至业务方，由业务方对相应事件进行分发处理，从而可以将触控操作统一通过事件处理对象传递至业务方。相比于iOS系统常规列表中单元格的事件均需要开发者在单元格类型定义时进行分发处理，分别将这些单元格事件通过代理方式传递给业务方而言，本实施例 的处理方式无需在不同业务使用列表中重复实现事件回调代理，从而使得操作更加便捷快速，并且有利于提高开发效率。
实施例二
图2示出了根据本公开实施例的一种列表显示方法的流程图，本实施例以上述实施例中各个可选方案为基础进行优化：在获取列表实例的待显示单元格对应的待显示数据和单元格类型之前，增加了“根据输入的创建参数创建列表实例，并调用列表实例的数据源加载接口加载数据源信息”。其中与上述实施例相同或相应的术语的解释在此不再赘述。
如图2所示，本公开实施例中提供的列表显示方法具体包括以下步骤：
S210、根据输入的创建参数创建列表实例，其中创建参数包括：需创建的列表实例类型和事件处理对象，事件处理对象用于对针对列表实例中各单元格中各控件的触控操作进行处理。
其中，列表实例类型可以是根据业务需求预先指定的底层列表类型。事件处理对象也可以是根据业务需求预先指定的，用于处理列表实例中每个单元格中每个控件的触控操作。单元格中的控件是指可以进行触控的部件，比如点赞按钮等。
示例性地，通过调用列表工厂Factory中的列表创建函数，根据输入的创建参数创建列表实例。
其中，列表创建函数可以是列表工厂Factory中预先定义的，用于根据输入的创建参数创建列表实例。列表工厂Factory是基于iOS系统内置的列表实现的，底层列表支持iOS系统的UITableView、UICollectionView或者UIScrollView列表，开发者可以通过列表工厂Factory中的列表创建函数创建列表实例。具体地，可以以输入的创建参数作为函数输入参数，调用列表工厂Factory中的列表创建函数，从而可以更加便捷地创建相应的列表实例。
需要注意的是，本实施例中的列表工厂Factory可以统一实现列表的数据源代理和事件回调代理，从而只需利用列表工厂Factory中的列表创建函数创建一个列表实例即可运行列表，从而可以进一步降低开发者的工作量，进一步提高了开发效率。本实施例中的列表工厂Factory可以屏蔽基于iOS系统的 常规列表之间的差异，以使开发者在使用列表时无法感知底层列表间的差异，从而可以灵活地切换列表类型，满足业务的长期迭代需求。
S220、调用列表实例的数据源加载接口加载数据源信息。
具体地，本实施例可以通过调用列表实例的数据源加载接口加载列表实例对应的数据源信息，从而可以通过接口的方式一次性注入数据，使得列表数据前后保持一致性。
S230、根据待显示的列表实例中的数据源信息，获取列表实例的待显示单元格对应的待显示数据和单元格类型。
S240、加载并解析预先生成的至少一个采用结构化语言的单元格描述文件，其中各单元格描述文件中存储有至少一种单元格类型对应的元数据，元数据包括子视图层级结构信息和属性设置信息。
示例性地，可以通过单元格描述文件加载器Loader，加载并解析预先生成的至少一个采用结构化语言的单元格描述文件。其中，单元格描述文件加载器Loader可以用于负责单元格描述文件的加载、解析以及单元格类型对应的元数据的维护。
S250、根据待显示单元格对应的单元格类型的元数据，创建单元格实例，并根据待显示数据对单元格实例进行渲染和显示。
示例性地，可以通过单元格生成器Generator，根据待显示单元格对应的单元格类型的元数据，创建单元格实例。其中，单元格生成器Generator可以服务于列表工厂，用于生成列表工厂所需要的单元格实例以及回收并缓存生成的单元格实例。
本公开实施例的技术方案，通过在获取列表实例的待显示单元格对应的待显示数据和单元格类型之前，可以根据输入的创建参数创建列表实例，并在创建列表实例后即可运行列表，无需重复实现列表的数据源代理和事件回调代理，从而提高了开发效率。并且通过利用数据源加载接口加载列表实例的数据源信息，从而可以保证列表数据的一致性。
实施例三
图3示出了根据本公开实施例的一种列表显示方法的流程图，本实施例 以上述实施例中的各个可选方案为基础，提供了一种优选实例。其中与上述各实施例相同或相应的术语的解释在此不再赘述。
如图3所示，本公开实施例中提供的列表显示方法具体包括以下步骤：
S310、调用列表工厂Factory中的列表创建函数，根据输入的创建参数创建列表实例。
其中，列表工厂Factory可以统一为列表实现数据源代理和事件回调代理，从而开发者只需要通过列表工厂Factory创建一个列表实例即可使用，进一步减少了开发者的工作量，提高了开发效率。
S320、调用单元格描述文件加载器Loader，动态加载并解析预先生成的至少一个采用结构化语言的单元格描述文件。
具体地，在运行阶段时，可以调用单元格描述文件加载器Loader，使得单元格描述文件加载器Loader可以动态加载并解析至少一个单元格描述文件。在采用结构化语言定义单元格类型时，可以为每个单元格类型预先指定了一个全局的唯一标识符，以便方便查询。
示例性地，Loader读取单元格描述文件后可以建立单例单元格子视图间的父子关系，形成子视图层级树，并将生成的子视图层级树进行缓存，以便后续可以直接使用，无需重复生成。
S330、将解析后的单元格类型对应的唯一标识符返回至列表工厂Factory中的列表实例，以使列表实例使用单元格类型对应的唯一标识符注册单元格类型。
具体地，当Loader解析完单元格描述文件后，将解析的所有单元格类型对应的唯一标识符返回至列表工厂Factory中的列表实例，从而列表实例可以将这些唯一标识符注册到底层使用的系统列表中，以使底层列表可以获得开发者提供的所有单元格类型。
S340、调用列表工厂Factory中列表实例的数据源加载接口加载数据源信息。
具体地，在开发者准备好列表的数据源时，可以通过调用列表实例的数据源加载接口来加载数据源信息。需要注意的是，列表工厂Factory可以屏蔽iOS系统底层列表间的差异，并通过对为开发者提供一致统一的接口，从而可 以允许开发者灵活地切换底层列表类型。
需要说明的是，本实施例不限定步骤S340执行时的执行顺序，比如步骤S340可以在步骤S330之后执行，也可以在步骤S320之前执行。
S350、调用列表工厂Factory中的数据获取函数，根据数据源信息，获取列表实例的待显示单元格对应的待显示数据以及对应的单元格类型的唯一标识符。
S360、将待显示单元对应的单元格类型的唯一标识符作为输入参数，调用单元格生成器Generator，检测缓存中是否存在该单元格类型对应的单元格实例，若是，则进入步骤S370；若否，则进入步骤S380。
S370、将缓存中的单元格类型对应的单元格实例返回至列表实例，并进入步骤S391。
具体地，在Generator缓存中存在对应的单元格实例时，将对应的单元格实例立即返回至列表实例中，从而缩短单元格实例的创建时间，提高列表的滑动性能。
S380、根据单元格类型对应的唯一标识符从单元格描述文件加载器Loader的缓存中提取对应的元数据。
具体地，在Generator缓存中不存在对应的单元格实例时，从Loader的缓存中提取单元格类型对应的唯一标识符对应的元数据。
S390、调用单元格生成器Generator中的单元格创建函数，根据提取的元数据创建单元格实例，并将创建的单元格实例返回至列表实例。
具体地，通过基于Generator根据提取的元数据创建对应的单元格实例，并将创建的单元格实例返回至列表工厂Factory中创建的列表实例。本实施例在列表实例使用的单元格实例被释放时，可以通过利用Generator回收并缓存该单元格实例，以便后续需要对相同类型的单元格进行显示时，可以直接读取缓存的单元格实例，提高列表的滑动性能。
需要注意的是，本实施例中的单元格类型使用结构化的描述语言进行描述，而不是原生语言进行定义，从而单元格实例的创建可以通过单元格生成器Generator自动完成，从而减少了开发者重复冗余的单元格实例的创建操作。
S391、调用列表工厂Factory中的渲染函数，根据待显示数据对单元格实 例进行渲染和显示。
本公开实施例的技术方案，通过调用列表单元格描述文件加载器Loader和列表工厂Factory可以动态加载列表单元格类型，从而实现了列表单元格定义和列表实例创建的解耦，并且也支持向列表动态的添加新的单元格类型，提高了列表配置的灵活性，以及列表显示的多样性。并且列表实例可以重复利用被列表释放的单元格实例，从而可以避免列表互动卡顿的情况，大大提高了列表的滑动性能。
以下是本公开实施例提供的列表显示装置的实施例，该装置与上述各实施例的列表显示方法属于同一个构思，在列表显示装置的实施例中未详尽描述的细节内容，可以参考上述列表显示方法的实施例。
