Operating system requirements: iOS 5.0 or later.
Mobile device: iPad.
This example describes some methods of working with a bubble tree data view. After starting the example the following operations are executed:
A bubble tree data view controller is created.
Bubble tree size and color legends are hidden.
A path to folder with the express report is determined, which data is used to create a bubble tree.
Executing the example requires to place the following code instead of the executeExample method of the ViewController class (see the Displaying of Express Report section):
-(void)executeExample {
// Remove all window subviews
NSArray *subviews = [self.view subviews];
for(UIView *subView in subviews) {
[subView removeFromSuperview];
}
// Get mobile device window size
CGRect windowFrame = [[self view] frame];
// Create a bubble tree controller
MABubbleTreeDataViewController *bubbleTreeController = [self createBubbleTreeDataViewController];
// Set bubble tree size
UIView *bubbleTreeView = [bubbleTreeController view];
[bubbleTreeView setFrame: windowFrame];
// Display bubble tree
[self.view addSubview: [bubbleTreeController view]];
}
-(MABubbleTreeDataViewController *)createBubbleTreeDataViewController {
// Get express report controller
MAExpressAnalysisReportViewController *contr = (MAExpressAnalysisReportViewController *)m_controller;
// Get express report delegate
EAReportDelegateImpl *delegate = [contr delegate];
// Create a bubble tree data source
SPPLPivot bubbleTreePivot = PPLPivot::pivot(m_olapReport);
SPPLPivotTable bubbleTreePivotTable = PPLPivotTable::pivotTable(bubbleTreePivot);
BubbleTreeDataViewDataSource *bubbleTreeDatasource = [[BubbleTreeDataViewDataSource alloc] initWithPivotTable:bubbleTreePivotTable];
// Create a bubble tree controller
MABubbleTreeDataViewController *bubbleTreeController = [[MABubbleTreeDataViewController alloc] initWithDataSource: bubbleTreeDatasource];
[bubbleTreeController setDelegate: contr];
[bubbleTreeController setTag: kViewModeBubbleTree];
[bubbleTreeController setIsDataViewTitleVisible: YES];
SNString plistPath = PPLFileManager::getReportPlistPath(m_olapReport->descriptor());
NSString* correctPath = plistPath?plistPath->nsString():NULL;
if (correctPath) {
correctPath = [correctPath stringByDeletingLastPathComponent];
[bubbleTreeController setPathToDirReport:correctPath];
NSLog(@"Path to report folder: %@", correctPath);
}
// Get report settings
SNDictionary sett = m_olapReport->settings();
SNDictionary treeMapSett = NULL; // Bubble tree settings
SNDictionary selectDict = m_olapReport->selectionDictionary();
if (sett) {
SNID treeMap = sett->objectForKey(NStr("treemap"));
// Get bubble tree settings
treeMapSett = (treeMap?treeMap->qClass<NDictionary>():NULL);
if (treeMapSett) {
// Load and apply bubble tree settings
[bubbleTreeDatasource loadSettings:treeMapSett withSelection:selectDict];
[bubbleTreeController setXmlNameSettingFromDic:(NSDictionary *)treeMapSett->nsObject()];
} else {
// Determine tree settings
[bubbleTreeController setXmlNameSetting];
}
}
// Hide size legend
[bubbleTreeController setIsSetSizeIndicator: NO];
[bubbleTreeController setIsSizeIndicator: [bubbleTreeController isSetSizeIndicator]];
// Hide color legend
[bubbleTreeController setIsSetColorIndicator: NO];
MADataViewType oldMode = kViewModeTable;
MADataViewType newMode = (MADataViewType)[bubbleTreeController tag];
// Synchronize dimensions between old and new data views
bool isNeedRefresh = [self syncDimensionsOldMode:oldMode newMode:newMode];
if (isNeedRefresh) {
// Update tree data
[delegate controllerViewDidLoaded];
}
return bubbleTreeController;
}
// Synchronizes dimensins between old and new data views
- (BOOL)syncDimensionsOldMode:(MADataViewType)oldMode newMode:(MADataViewType)newMode
{
bool result = NO;
if (oldMode == newMode) {
return NO;
} else {
result = YES;
};
DataViewDatasource *src = [self datasourceByViewType: oldMode];
DataViewDatasource *dst = [self datasourceByViewType: newMode];
if ([src conformsToProtocol:@protocol(DataViewDatasourceSyncSelection)] && [dst conformsToProtocol:@protocol(DataViewDatasourceSyncSelection)]) {
id <DataViewDatasourceSyncSelection> source = (id<DataViewDatasourceSyncSelection>)src;
id <DataViewDatasourceSyncSelection> dest = (id<DataViewDatasourceSyncSelection>)dst;
DataViewDatasourceDimensionsInfo info;
[source copyDatasourceDimensionsInfo:&info];
result = [dest applyDatasourceDimensionsInfo:&info];
}
return result;
}
- (DataViewDatasource *)datasourceByViewType:(MADataViewType)type {
// Get express report controller
MAExpressAnalysisReportViewController *contr = (MAExpressAnalysisReportViewController *)m_controller;
// Get express report delegate
EAReportDelegateImpl *delegate = [contr delegate];
switch (type) {
case kViewModeTable: return delegate.gridDatasource;
case kViewModeChart: return delegate.chartDatasource;
case kViewModeMap: return [delegate mapDatasource];
case kViewModeBubble: return [delegate bubbleDatasource];
case kViewModeBubbleTree: return [delegate bubbleTreeDatasource];
case kViewModeTreeMap: return [delegate treeMapDatasource];
default: return nil;
}
}
After executing the example the bubble tree data view is displayed: Color and size legends are hidden:
The development environment console displays the path to the express report folder, which data is used to create the bubble tree:
Report folder path: /Users/sea/Library/Application Support/iPhone Simulator/7.1/Applications/AC4804D8-C173-4008-B14D-4A2401B0B49D/Documents/repositories/910419CE79EA52E95F2F8FE76E7C24DE/OBJ21110
