Working with Regular Report Page Selection View

Operating system requirements: iOS 5.0 or later.

Mobile device: iPad.

Description

This example describes some methods of working with regular report page selection view. After starting the example the following operations are executed:

Regular report page selection view is retrieved.
Page thumbnail size, array of thumbnail center coordinates, scrolling region height are retrieved from page selection view.
Page index is searched by specified vertical indent.

Source Code

Executing the example requires to place the following code in the body of the executeExample method of the ViewController class (see the Displaying of Regular Report section):

// Get regular report object
MAProceduralReportViewController *proceduralReportController = (MAProceduralReportViewController *)m_controller;
// get array of regular report data views
NSArray *dataViewControllers = [proceduralReportController dataViewControllers];
// Parse regular report views in cycle
for( UIViewController *controller in dataViewControllers)
{
    // Check if the current view is a regular report sheet viewer
    if([controller isMemberOfClass:[MAProceduralReportDataViewController class]])
    {
        // Get sheet viewer view
        MAProceduralReportDataViewController *dataViewController =(MAProceduralReportDataViewController *)controller;
        // Get regular report viewer view
        MAProceduralReportDataViewControllerBase *reportDataViewControllerBase = (MAProceduralReportDataViewControllerBase *)dataViewController;
        // Get page selection view
        PdfPageSelector *pageSelector = [reportDataViewControllerBase pageSelector];
        // Get page thumbnail size
        CGSize thumbnailSize = [pageSelector thumbnailSize];
        // Display page thumbnail height and width in the development environment console
        NSLog(@"Page thumbnail height: %f",thumbnailSize.height);
        NSLog(@"Page thumbnail width: %f",thumbnailSize.width);
        // Get array of thumbnail center coordinates
        NSMutableArray *coordinates = [pageSelector thumbnailsCoordinates];
        // Get first thumbnail coordinate in array
        float coordinate = [[coordinates objectAtIndex:0] floatValue];
        // Display first thumbnail coordinate in array in the development environment console
        NSLog(@"First thumbnail center coordinate in array of thumbnail center coordinates: %f", coordinate);
        // Display scrolling region height in the development environment console
        NSLog(@"Scrolling region height: %f",[pageSelector scrollingHeight]);
        // Find page index by specified vertical indent
        int pageForCoord = [pageSelector findPageNumberForYCoord:260];
        NSLog(@"Page index for indent 260: %d",pageForCoord);
        // Determine whether page selection view is hidden
        [pageSelector performSelector:@selector(setHidden:) withObject:[NSNumber numberWithBool: NO]];
    }
}

After executing the example the mobile device screen displays the regular report, for which page selection view is additionally drawn:

The development environment console also displays information on displaying the page selection view in regular report:

Page thumbnail height: 59.424404

Page thumbnail width: 42.000000

First thumbnail coordinate in array of thumbnail center coordinates: 49.712204

Scrolling region height: 337.122040

Page index for indent 260: 3
