Description
Technical Field
The invention relates to the technical field of TableView (UITableView) control use and optimization in IOS (iOS), in particular to a method for refreshing a video playing Cell at no interval.
Background
In the existing iOS system, the display of a human-computer interaction view in a form of table data is supported, and a colorful UI effect can be brought to a user.
In the iOS system, to realize table data display, the most common practice is to generate a table view using UITableView, which inherits from uiScrollView, thus supporting vertical scrolling and having excellent performance. In the table view, each row is a UITableViewCell object, and a user-scrollable multi-row single-column list is formed by the UITableViewCell objects.
UITableView has both grouping and non-grouping styles and can be set in the storeboard or by code. The table view may also add index values thereto, such as a right index list in the address book, each index entry corresponding to its section header title.
In use, the UITableView requires a data source (dataSource) to display data, and the UITableView queries the data source for how many rows of data are in total and what data are displayed on each row, etc. All OC objects that comply with the UITableView datasource protocol may be data sources of the UITableView. The process of presenting data is generally as follows:
(1) inquiring a data source, and acquiring the total data of how many groups need to be displayed;
(2) inquiring each group of data, and acquiring the number of rows of data to be displayed in each group;
(3) and inquiring each row of data to obtain the specific content displayed by each row.
When a video is displayed and played, the UITableViewCell object needs to display a corresponding video, and then the multi-line single-column list is composed of a plurality of video playing cells (videocells). When the data source is changed, all cells (uitableviewcells) of TableView need to be reloaded, and the cells are refreshed. There are several refreshes of TableView in iOS:
the first method comprises the following steps: refresh of tableview [ self.
The reloadData is the refresh of the entire UITableView, and sometimes we may need a partial refresh. Such as: refresh only one Cell, refresh only one section, etc. When the reloadData method is called at this time, although the user cannot see the method, some methods waste resources.
And the second method comprises the following steps: cell with local refresh
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath，nil]withRowAnimation:UITableViewRowAnimationFade];
This allows the first Cell of the first section to be refreshed easily. Although it appears that there is more code, it is really a better resource saving. Minimal refresh is also an optimization of UITableView.
And the third is that: partial refresh section
NSIndexSet *indexSet = [[NSIndexSet alloc]initWithIndex:0];
[self.tableView reloadSections:indexSet withRowAnimation:UITableViewRowAnimationFade];
The section of code above is the refresh section 0.
However, in the existing technical solution, a stuck phenomenon occurs during the refresh, and the stuck phenomenon is particularly prominent when TableView slides, which affects the use experience. The reason for this is probably because the refreshing mechanism of the UITableViewCell is to extract a new Cell from the Cell cache for updating, thereby affecting the video being played.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a method for refreshing a video playing Cell without intervals, wherein the video playing is not influenced by the Cell refreshing, the video playing is not blocked due to the Cell refreshing when the data source is changed, the algorithm is simple, the effect is good, and the user experience is improved.
In order to achieve the above purposes, the technical scheme adopted by the invention is as follows:
a method for refreshing a video playing Cell without intervals is characterized by comprising the following steps:
when the video playing Cell receives the click playing ClickPlay event, the shared instance is called to create and return to the video window VideoBox singleton,
the returned video view VideoBox is added to the video playing Cell in a single instance,
the video playing Cell sends a video playing request to the data service platform data service, inquires the relevant information of the video to be played,
when the video playing Cell triggers a Cell refreshing event, the video window VideoBox continues to play the video in a single case, only the video playing Cell refreshes,
and after the video playing Cell is refreshed, restoring the video window VideoBox to the video playing Cell in a single case.
On the basis of the technical scheme, the data service platform DataService receives a video playing request sent by the video playing Cell, triggers and acquires a related song fetchRelateSong event,
judging whether the video requested to be acquired exists or not according to the information carried in the request,
when no relevant video exists, the error information is returned,
when the relevant video exists, packaging the video information into an information update data packet update info, calling a custom refresh class reload tablelndex, and returning the update data packet update info to the video playing Cell.
On the basis of the above technical solution, the update data packet updateInfo includes a refresh identifier, and the refresh identifier is used to enable the video playing Cell receiving the identifier to perform a refresh operation.
On the basis of the technical scheme, after the video playing Cell receives the update data packet updateInfo, the video playing Cell analyzes the data packet to obtain a refresh identifier, and triggers a Cell refresh event updatewithin.
According to the method for refreshing the video playing Cell without intervals, the video playing is not influenced by the refreshing of the Cell, the video playing is not blocked due to the refreshing of the Cell when the data source is changed, the algorithm is simple, the effect is good, and the user experience is improved.
Drawings
The invention has the following drawings:
FIG. 1 is a flow chart of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the method for refreshing a video playing Cell without intervals according to the present invention includes the following steps:
when the video playing Cell receives the click playing ClickPlay event, the shared instance is called to create and return to the video window VideoBox singleton,
the returned video view VideoBox is added to the video playing Cell in a single instance,
the video playing Cell sends a video playing request to the data service platform data service, inquires the relevant information of the video to be played,
when the video playing Cell triggers a Cell refreshing event, the video window VideoBox continues to play the video in a single case, only the video playing Cell refreshes,
and after the video playing Cell is refreshed, restoring the video window VideoBox to the video playing Cell in a single case.
In the scheme, the video window VideoBox single case is not affected by the refreshing of the video playing Cell, so that the video playing is ensured to be free of pause, the video playing Cell can also complete refreshing according to the command, and the video window is ensured to be free of intervals when the video playing Cell refreshes.
On the basis of the technical scheme, the data service platform DataService receives a video playing request sent by the video playing Cell, triggers and acquires a related song fetchRelateSong event,
judging whether the video requested to be acquired exists or not according to the information carried in the request,
when no relevant video exists, the error information is returned,
when the relevant video exists, packaging the video information into an information update data packet update info, calling a custom refresh class reload tablelndex, and returning the update data packet update info to the video playing Cell.
On the basis of the above technical solution, the update data packet updateInfo includes a refresh identifier, and the refresh identifier is used to enable the video playing Cell receiving the identifier to perform a refresh operation.
On the basis of the technical scheme, after the video playing Cell receives the update data packet updateInfo, the video playing Cell analyzes the data packet to obtain a refresh identifier, and triggers a Cell refresh event updatewithin.
Those not described in detail in this specification are within the skill of the art.
