Detailed description of the invention
The method of the present invention is applicable to the UITableView of MVVM pattern, and MVVM i.e. Model-View-
View model (Modle-View-ViewModle), (User Interface is called for short UI i.e. user interface
UI).Fig. 1 is the structural representation of MVVM, as it is shown in figure 1, MVVM is made up of three parts:
Modle, View and ViewModle, View i.e. UI, ViewModle are the abstract of View, are responsible for
Information conversion between View and Model, is sent to Modle, Model i.e. by the Command of View
Data access layer.
ViewModle is mainly improved by the present invention, the method for following example also by
ViewModle perform, in order to distinguish existing ViewModle, the present invention will improve after ViewModle
It is referred to as TableViewModel, below will be described in detail the operation principle of TableViewModel, and
The class used in TableViewModel:
1.1 classes TableViewSectionData
Core attribute:
NSArray*rowDatas；
id headData；
id footData；
Core methed:
(TableViewSectionMutableData*)；
Wherein, attribute rowDatas is an array of data type id, and it is meant that a section
In data in all row.One UI includes that multiple section, each section include multiple row.
Attribute headData represents the required data shown of headView of a section, if belonged to
Property headData be empty, then explanation need not show headView.
Attribute footData represents the required data shown of footView of a section, if
FootView is empty, then explanation need not show footView.
The effect of method mutableCopy is that one data of return are on all four with itself
TableViewSectionMutableData, to provide outside to modify.
1.2 classes TableViewSectionMutableData
Core attribute:
NSMutableArray*rowDatas；
id headData；
id footData；
Core methed:
(TableViewSectionData*)copy；
Wherein, attribute rowDatas is a variable data array of data type id, and it is meant that one
Data in all row in section.
Attribute headData is consistent with TableViewSectionData implication, and attribute footData is same
TableViewSectionData implication is consistent.
The effect of method mutableCopy is that one data of return are on all four with itself
TableViewSectionData, to provide UITableView to be shown data.
1.3 classes TableViewDataSource
Core attribute:
NSArray*sectionDatas；
id headData；
id footData；
Core interface:
-(TableViewSectionData*)sectionDataInSection:(NSInteger)section；
-(TableViewMutableDataSource*)mutableCopy；
Wherein, attribute sectionDatas is an array of TableViewSectionData object, it
It is meant that the data of all section in a UITableView.
Attribute headData represents the required data shown of headView of a UITableView,
If headData is empty, then explanation need not headView.
Attribute footData represents the required data shown of footView of a UITableView, as
Really footView is empty, then explanation need not show footView.
The effect of method mutableCopy is that one data of return are on all four with itself
TableViewMutableDataSource, to provide outside to modify.
1.4 classes TableViewMutableDataSource
Core member's variable:
NSMutableArray*sectionDatas；
id headData；
id footData；
Core interface:
-(TableViewSectionMutableData*)sectionDataInSection:(NSInteger)
section；
-(TableViewDataSource*)copy；
Wherein, attribute sectionDatas this be a variable data array of TableViewSectionData object,
It is meant that the data of all section in a UITableView.
Attribute headData is consistent with TableViewDataSource, and attribute footData is same
TableViewDataSource is consistent.
The effect of method mutableCopy is that one data of return are on all four with itself
TableViewDataSource, to provide UITableView to be shown.
1.5 classes TableViewModel
Core member's variable:
TableViewDataSource*currentDataSource；
TableViewMutableDataSource*_nextDataSource；
Core attribute:
UITableView*tableView；
Core interface:
(TableViewMutableDataSource*)nextDataSource；
(TableViewDataSource*)currentDataSource；
(void)reloadData；
1.5.1 core member's variable lexical or textual analysis
A ,-currentDataSource represent dataSource (data source) current for UITableIView,
Here dataSource is not the dataSource in UITableView, UITableView's
DataSource is meant that the agency providing data source, and data source here is exactly
_ currentDataSource, in order to distinguish both, is referred to as the attribute dataSource of UITableView
DataSource acts on behalf of.
B ,-nextDataSource represent the dataSource that UITableView is following, and wherein, future refers to
Be next time reloadData time, nextDataSource will become the dataSource of UITableView,
So the change of any nextDataSource, will be represented when reloadData next time,
NextDataSource can be created and be initialised when TableViewModel is initialized.
1.5.2 core attribute lexical or textual analysis:
A, tableView are incoming by outside, and effect is at reloadData method intrinsic call tableView
ReloadData method.
1.5.3 core interface lexical or textual analysis:
a、-(TableViewMutableDataSource*)nextDataSource；
The external world obtains the Future Data of UITableView by calling this interface and is modified it.
b、-(TableViewDataSource*)currentDataSource；
The external world obtains the current data source of UITableView, the data got by calling this interface
Need to be demonstrated immediately.Note: actually member variable _ nextDataSource's that this interface returns
Immutable copy, preventing under multithreading _ currentDataSource sudden change causes crash.
c、-(void)reloadData；
This interface is consistent with the reloadData function of UITableView, is all after data source changes
For refreshing interface, actually the method is the most also the reloadData side calling UITableView
Method.They maximum differences are, reloadData method, before real refreshing interface, can carry out data source
Switching:
_ currentDataSource=[_ nextDataSource copy]；
1.6TableViewModel (viewModel) and UITableVIewController
(viewController), the concrete steps that UITableView (tableView) is used in combination can refer to figure
2, Fig. 2 is UITableView flush mechanism flow chart, as in figure 2 it is shown, UITableView refreshes machine
System comprises the following steps:
Step 101, in the viewDidLoad method of viewController generate viewModel,
tableView。
Step 102, the dataSource agency that viewController is set to tableView and delegate
Agency, and the tableView attribute of viewModel is pointed to tableView.
Step 103, viewController loading data, load after terminating, call viewModel's
-(TableViewMutableDataSource*) nextDataSource method obtains data source more new data
Source.
Step 104, the reloadData method calling viewModel start to update UITableView interface.
Step 105, the delegate Proxy Method performing UITableView and dataSource agent
Method, is obtained by (TableViewDataSource*) currentDataSource method of viewModle
Data source.
Step 106, interface are refreshed complete.
In conjunction with the operation principle of the TableViewModel of foregoing description, and UITableView refreshes machine
System, the embodiment of the present invention one provides the method for refreshing of a kind of user interface, and Fig. 3 is the embodiment of the present invention one
The flow chart of the method for refreshing of the user interface provided, as it is shown on figure 3, the method bag that the present embodiment provides
Include following steps:
Step 201, when the data of user interface are updated, Future Data source is modified, future
Data source is the data source of next update data.
Here Future Data source, the nextDataSource of the most above-mentioned TableViewModle.Such as,
Get new data, need when the first row of user interface inserts a line, call TableViewModle
NextDataSource method, obtain table data source TableViewMutableDataSource, i.e. obtain
Take the data source of all section in user interface, and acquisition section is 0 again
TableViewSectionMutableData.Then at the attribute of TableViewSectionMutableData
RowData inserts a data.
If step 202 delay timer is not opened, then start delay intervalometer, delay timer is used for
The delay refresh time of record user interface.
After Future Data source is modified, it is judged that whether delay timer is opened, and delay timer exists
Generating when TableViewModle initializes, the delay refresh time of delay timer can be according to actual need
Arrange, for example, 1 second.If delay timer is not opened, then start delay intervalometer, if prolonged
Intervalometer has been switched on late, then terminate, and does not perform any operation, waits delay timer then.
Step 203, when delay timer is to constantly, Future Data source is copied to current data source, when
Front data source is the data source of current display data.
The method of the present embodiment, by defining two variable Future Data sources inside TableViewModle
With current data source, Future Data source variable, current data source be can not variable, when there being data to update,
Can update Future Data source immediately, current data source can't update immediately, only arrives when delay timer
Constantly, just the value in Future Data source can be copied to current data source, the value in current data source is once changed
Become, can display the most on a user interface.By arranging delay timer, it is to avoid at short notice
Repeat to refresh repeatedly to user interface, delay timer then before, every secondary data update time be not true
The most more new data, only when delay timer is to constantly, just can trigger real renewal operation.Postponing
May carry out in refresh time repeatedly updating, this repeatedly updates unification after being delayed by and once refreshes.
Reproduction process can be expressed as-currentDataSource=[-nextDataSource copy].
It addition, the method for the present invention can also solve to cause UITableView to have shown that because time delay refreshes
Data and its data source be inconsistent and the series of problems that causes.
Step 204, according to current data source perform method for refreshing data, refreshes user interface.
After Future Data source is copied to current data source, TableView performs method for refreshing data
ReloadData, refreshes user interface.
Step 205, closedown delay timer.
When follow-up have data to update time, repeat above-mentioned steps.
The method of the present embodiment, by defined in TableViewModel two variablees: Future Data source
With current data source, when the data of user interface are updated, Future Data source is modified, now
Not real refreshes user interface, but when delay timer is to constantly, just by the value in Future Data source
It is copied to current data source, carries out Refresh Data.Avoid in the short time frequently to user by postponing refreshing
Interface is refreshed.
On the basis of embodiment one, in other embodiments of the invention, all right after step 201
Comprising the steps: to add 1 by the value of refresh counter, refresh counter postpones the secondary of refreshing for recording
Number, and after step 205, i.e. complete in refreshing, after closing delay timer, by refresh count
The value of device is set to 0.Wherein, the initial value of refresh counter is 0, when often needing to update a secondary data, and brush
The value of refresh counter will add 1, such as, when user interface is updated 3 times, and the value of refresh counter
Being 3, when user interface is updated 5 times, the value of refresh counter is 5.Merely just from increasing refreshing meter
Number device, the actually the most real data that perform update, and data update or at delay timer to constantly,
Just carry out data renewal.
On the basis of the operation principle of above-described embodiment one and the TableViewModel of definition, Fig. 4 is
The flow chart of the method for refreshing of the user interface that the embodiment of the present invention two provides, as shown in Figure 4, this enforcement
The method that example provides may comprise steps of:
Step 301, get new data, need to insert a line in the first row.
Step 302, call the nextDataSource method of TableViewModel, obtain table data
Source TableViewMuTableDataSource, and again to get section be 0
TableViewMuTableData。
Step 303, insertion one in the attribute rowData of TableViewSectionMuTableData
Data.
Step 304, call the reloadData method of TableViewModle.
Step 305, the value of refresh counter add 1.
Step 306, judge whether delay timer is opened.
If delay timer is not opened, then perform step 307, if delay timer is opened, then hold
Row step 308.
Step 307, unlatching delay timer.
Step 308, end.
Step 309, delay timer callback method are triggered.
Step 310, start to perform callback method.
Step 311 ,-currentDataSource=[-nextDataSource copy].
Step 312, TableView perform reloadData.
Step 313, the value of refresh counter are set to 0.
Step 314, closedown delay timer.
Step 315, timer callback method terminate.
On the basis of above-described embodiment one and embodiment two, the embodiment of the present invention three provides a kind of data multiple
Method processed, the data between Future Data source and current data source that Fig. 5 provides for the embodiment of the present invention three
Clone method, the method for the present embodiment realizes based on above-mentioned TableViewModel, as it is shown in figure 5,
The method that the present embodiment provides may comprise steps of:
Step 401, start to perform the copy method of TableViewSectionMuTableData.
Step 402, newly-built TableViewDataSource, NSMuTableArray.
Wherein, TableViewDataSource is newData, and NSMuTableArray is newArray.
Step 403, newData.headData=self.headData, newData.footData=self.footDa
Ta。
Step 404, traversal sectionDatas obtain sectionData.
Step 405, judge traversal whether terminate.
If traversal terminates, then perform step 406, if traversal is not over, perform step 409.
Step 406, NSArray array=[newArray copy].
Step 407, newData.sectionData=array.
Step 408, return newData.
Step 409, TableViewSectionData newSectionData=[sectionData copy].
The specific implementation of step 409 can be: first newly-built newSectionData, then performs
NewSectionData.headData=self.headData,
NewSectionData.footData=self.footData,
NewSectionData.rowData=[self.rowDatacopy], finally performs newArray
addObject:newSectionData。
On the basis of above-described embodiment one, after delay timer is then, Future Data source is replicated
Before current data source, it is also possible to judge that user interface the most shows, if user interface shows
Show, then Future Data source is copied to current data source.If user interface is not to show, then close
Delay timer.If user interface shows, then illustrate that user is current just at browsing user interface,
Need to display more new data immediately, in order to user can see more new data in time, if used
Interface, family is not currently displayed, then more new data does not displays, immediately even if because displaying
, user also will not go to see, having little significance of renewal.If user interface is not to show, will not
User interface is updated, follow-up when user actively opens user interface, it is judged that refresh counter
Whether value is 0, when the value of refresh counter is not 0, performs method for refreshing data, refreshes user circle
Face, during to ensure that user actively opens user interface, can obtain the data of renewal at once.When refreshing meter
When the value of number device is 0, illustrates do not have data to be updated, be now not required to user interface is refreshed,
The state keeping user interface is constant such that it is able to avoid user the most actively to open interface all to boundary
Face is refreshed, effectively save data traffic, and improves Consumer's Experience.In order to realize above-mentioned user interface
Not at currently displaying not refreshes user interface, need TableViewModel is added to expand attribute and side
Method.
Attribute:
BOOL isShow；
Method
-(void)viewWillAppear；
-(void)viewWillDisappear；
Wherein, attribute isShow represents that UITableView the most shows, method viewWillAppear
Calling when UITableView i.e. will appear from, method viewWillDisappear as UITableView is
Call during by disappearance.
Accordingly, in embodiment two before step 311, it is judged that isShow==true is the most correct, as
Really isShow==true is correct, then perform step 311, if isShow==true is incorrect, then
Perform step 314.
Further, on the basis of embodiment one, before start delay intervalometer, it is also possible to further
Judge that user interface the most shows, if user interface shows, then start delay intervalometer, if
User interface is not to show, then not start delay intervalometer, waits and updating next time.User interface
It is not currently displayed, illustrates that user has had been moved off the user interface being updated, update the most immediately and do not have
What meaning, thus need not opening timing device, triggering following renewal operation.
