Operating system requirements: iOS 5.0 or later.
Mobile device: iPad.
This example describes some methods of working with a table data view. After starting the example the following operations are executed:
A table data view controller is created by means of express report delegate.
It is determined and checked if there is a table selection start area.
A cell selection start area is set in a table data view.
The specified row height is set.
The specified column width is set.
Table data view data source is refreshed.
Executing the example requires to place the following code in the body of the executeExample method of the ViewController class (see the Displaying of Express Report section):
// Delete all window subviews
NSArray *reportSubviews = [self.view subviews];
for(UIView *subView in reportSubviews)
{
[subView removeFromSuperview];
}
// Create a report delegate
EAReportDelegateImpl *delegate = [[[EAReportDelegateImpl alloc] initWithOlapReport:m_olapReport] autorelease];
// Create a dashboard controller
MAExpressAnalysisReportViewController *report = [[[MAExpressAnalysisReportViewController alloc] initWithDelegate:delegate] autorelease];
// Create a table view controller object
MAGridDataViewController *gridController = [[MAGridDataViewController alloc] initWithDatasource:(GridDataViewDatasource *)delegate.gridDatasource];
// Determine whether table title is visible
gridController.isDataViewTitleVisible = NO;
// Set table data view controller delegate
gridController.delegate = report;
// Set additional custom data
gridController.tag = kViewModeTable;
// Create an array of controllers and add table data view controller to it
NSMutableArray *controllers = [NSMutableArray array];
[controllers addObject:gridController];
// Set array of report view controllers
report.dataViewControllers = controllers;
// Delete dimension container view in report
report.splitViewController.panelViewController = nil;
// Display report containing table
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:report];
[self.view addSubview: navController1.view];
// Determine whether there is table selection start area
[gridController setNoStartupSelection:NO];
if([gridController noStartupSelection] == NO)
{
// Create and fill array of column indexes
NSMutableArray *columns = [[NSMutableArray alloc] init];
NSNumber *number = [NSNumber numberWithInt: 1];
[columns addObject: number];
NSNumber *number1 = [NSNumber numberWithInt: 2];
[columns addObject: number1];
// Create and fill array of row indexes
NSMutableArray *rows = [[NSMutableArray alloc] init];
NSNumber *number2 = [NSNumber numberWithInt: 1];
[rows addObject: number2];
NSNumber *number3 = [NSNumber numberWithInt: 2];
[rows addObject: number3];
// Create a cell selection area
MAGridDataViewControllerSelection *selection = [MAGridDataViewControllerSelection selectionWithColumns:columns rows:rows type:@"" deductHeaderIndex: NO];
// Set cell selection start area in table data view
[gridController setStartupSelection:selection];
}
// Set specified row height
[gridController setHeight:100 toRow: 1];
// Set specified column width
[gridController setWidth:200 toColumn: 1];
// Refresh table data view data source
[[gridController gridDatasource] updateAsync];
After executing the example the mobile device screen displays the table, for which cell selection is set, and also height and width of the specified rows and columns are changed:
Then replace the code string:
MAGridDataViewController *gridController = [[MAGridDataViewController alloc] initWithDatasource:(GridDataViewDatasource *)delegate.gridDatasource];
is replaced with the following string:
MAGridDataViewController *gridController = [[MAGridDataViewController alloc] initWithDatasource:(GridDataViewDatasource *)delegate.gridDatasource themeUid:ttpsRed];
After executing the updated example the mobile device screen displays the table with changed color scheme:
