Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
In order to solve the problem of gesture collision when horizontal scrolling and multi-level vertical scrolling exist in a page at the same time, the embodiment will first introduce a method for constructing a multi-view hierarchical management system based on iOS.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for constructing an iOS-based multi-view hierarchical management system according to an embodiment of the present application. In the present embodiment, the construction method of the multi-view hierarchy management system may be applied to an electronic device, including step S11, step S12, and step S13.
First, the electronic device may perform step S11.
Step S11: adding a tableView _1 at the bottom layer of the View controller, and adding a View at the head of the tableView _1, wherein the frame of the tableView _1 is full screen and is used for longitudinal scrolling, and a cell is arranged at the data source of the tableView _ 1.
In this embodiment, the electronic device may create a View controller (i.e., a View controller) in response to an operation of a developer, add a tableView _1 to a bottom layer of the View controller, where a frame (i.e., a frame) of the tableView _1 is full screen uiscreen. Thereafter, a cell may be set at the data source of tableView _ 1.
Then, the electronic apparatus may perform step S12.
Step S12: and adding a scrollView with the same size on the cell for transverse rolling, wherein contentsize of the scrollView is divided into n pages of rolling distance on the left and right in the transverse direction, and is fixed vertically.
In this embodiment, the electronic device may respond to an operation of a developer, add a scrollView having the same size as the cell on the cell, and perform a horizontal scroll, so that a contentsize of the scrollView scroll is fixed in a vertical direction, and n pages of scroll distances can be divided in a horizontal direction and in a left-right direction, where the n pages of scroll distances can be adjusted according to a development requirement. For example, the scrolling distance is divided into 4 pages in the lateral direction, and the present invention is not limited thereto.
After the scrollView is added and set, the electronic device may perform step S13.
Step S13: adding n tableview _2 on the scrollView, and spreading the tableview _2 on the scrollView, wherein each tableview _2 occupies a page rolling distance of the scrollView, and each tableview _2 is used for performing longitudinal rolling.
In this embodiment, the electronic device may add n tableview _2 on the scrollView in response to an operation of the developer, and lay the n tableview _2 on the scrollView, where each tableview _2 occupies a page scrolling distance of the scrollView. Therefore, each tableview _2 can scroll longitudinally, and since the bottom is scrollview, the tablevew can also scroll transversely. Here, when the contentsize of the scrollView scroll is divided by 4 page scroll distances in the lateral direction, the number of tableview _2 is also 4.
In addition, the electronic device can inherit the UIGesturre recognizizer under the operation of a developer, realize a locationInView method and a locationOfTouch method, and is used for acquiring the position of the finger drop point touch View of the user.
Then, a mapping area corresponding to the tableView _1 may be established based on the touch event type of the tableView _1, and a mapping area corresponding to the tableView _2 may be established based on the touch event type of each tableView _ 2.
For example, the touch event types of the tableView _1 include an a type, a B type, and a C type, and the touch event types of the 4 tableView _2 are a D type, an E type, an F type, and a G type, respectively. Then, the mapping area corresponding to tableView _1 covers the areas where the type a, type B and type C touch events are triggered by the position where the user's finger drop point touches View, and the mapping area corresponding to tableView _2 covers the areas where the type D, type E, type F and type G touch events are triggered by the position where the user's finger drop point touches View (even the mapping area corresponding to each tableView _2 may be subdivided).
Based on the method, the multi-view hierarchical management system based on the iOS can be constructed. The page layout hierarchy of the constructed iOS-based multi-view hierarchical management system is shown in fig. 2.
Based on the iOS-based multi-view hierarchical management system, the electronic device can run the iOS-based multi-view hierarchical management method.

In this embodiment, in the iOS-based multi-view hierarchical management system, a tableView _1 is located at the bottom layer of a view controller, a frame of the tableView _1 is a full screen and is used for performing longitudinal scrolling, a headgroup of the tableView _1 is provided with a headreviview, a size of a scrollView is consistent with a size of a cell set by a data source of the tableView _1 and is arranged on the cell and is used for performing lateral scrolling, contentsize for scrolling of the scrollView is fixed in the longitudinal direction, n page scrolling distances are divided in the lateral direction and the left direction, n tableView _2 are laid on the scrollView, each tableView _2 occupies a page scrolling distance, and each tableView _2 is used for performing longitudinal scrolling.
Then, the electronic device may obtain the scrolling positions of tableView _1 and tableView _2 by using a listening scrollView scrolling agent based on the iOS-based multi-view hierarchical management system. Judging the monitored rolling position of tableView _1 or tableView _ 2:
if the scroll position of tablevew _1 is monitored, the electronic device can judge whether the scroll position reached after tablevew _1 scrolls upwards exceeds the longitudinal height of the headerView.

Step S22: and when the reached scrolling position after the tableView _1 is scrolled upwards exceeds the longitudinal height of the headView, closing the scrollable state of the tableView _1 and opening the scrollable state of each tableView _ 2.
In this embodiment, when the scrolling position reached after the tableView _1 scrolls upwards exceeds the longitudinal height of the headview (the headview scrolls along with the scrolling of the tableView _1), the headview is scrolled out of the screen visually from the user, and at this time, the scrollable state of the tableView _1 may be closed, and the scrollable state of each tableView _2 may be opened.
If it is monitored that the scrolling position of the tableView _2 is the currently controlled tableView _2 (that is, any one of the n tableviews _2 may be in a controlled state under the operation of the user), the electronic device may determine whether the scrolling position of the tableView _2 reaches the top.
When the scroll position of this tableView _2 (i.e., the currently controlled tableView _2) reaches the top, step S23 is performed.
Step S23: after the scrolling position of any tablevew _2 currently controlled reaches the top, the scrollable state of each tablevew _2 is closed, and the scrollable state of tablevew _1 is opened.

When the view slides left and right, the paging effect set by the scrollview can divide the pages by a plurality of tableview at the bottom, so that the pages can be switched by sliding left and right, and the complex page design effect is realized. Moreover, the tableView is adopted, so that the practicability is high; the page is switched in a transverse rolling mode by utilizing the paging attribute of the ScrollView, the offset does not need to be calculated, and the method is very efficient and convenient; through linkage of the two tableViews, the on and off of the scrollable state is set by utilizing the offset, the problem of gesture conflict when multilayer longitudinal scrolling (longitudinal scrolling of different layered views) simultaneously exists can be effectively solved, and the self-contained headerView of the tableView _1 is utilized to realize up-and-down scrolling without specially calculating the linkage of the headerView, so that the method is very simple and efficient.
