I'm trying to create an iPad application with a similar user interface to Apple's Mail application, i.e:
RootView controller (table view) on the left hand side of the split view for navigation with a multiple view hierarchy. When a table cell is selected a new table view is pushed on the left hand side
The new view on the left side can update the detail view.
I can accomplish both tasks BUT NOT TOGETHER.
I mean I can make a multi-level table view in the RootController.(HERE you can find the working source code).
Or I can make a single-level table view in the RootController which can update the detailViewController (here there is the source code:http://www.megaupload.com/?d=D6L0463G).
Can anyone tell me how to make a multi-level table in the RootController which can update a detailViewController?
There is more source code at the link but below is the method in which I presume I have to declare a new detailViewController (which has to be put in the UISplitViewController):
- (void)tableView:(UITableView *)TableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row];
//Get the children of the present item.
NSArray *Children = [dictionary objectForKey:@"Children"];
//
if([Children count] == 0) {
/*
Create and configure a new detail view controller appropriate for the selection.
*/
NSUInteger row = indexPath.row;
UIViewController <SubstitutableDetailViewController> *detailViewController = nil;
if (row == 0) {
FirstDetailViewController *newDetailViewController = [[FirstDetailViewController alloc]initWithNibName:@"FirstDetailView" bundle:nil];
detailViewController = newDetailViewController;
}
if (row == 1) {
SecondDetailViewController *newDetailViewController = [[SecondDetailViewController alloc]initWithNibName:@"SecondDetailView" bundle:nil];
detailViewController = newDetailViewController;
}
// Update the split view controller's view controllers array.
NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil];
splitViewController.viewControllers = viewControllers//nothing happens.....
[viewControllers release];//
}
else {
//Prepare to tableview.
RootViewController *rvController = [[RootViewController alloc]initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]];
//Increment the Current View
rvController.current_level += 1;
//Set the title;
rvController.current_title = [dictionary objectForKey:@"Title"];
//Push the new table view on the stack
[self.navigationController pushViewController:rvController animated:YES];
rvController.tableDataSource = Children;
[rvController.tableView reloadData]; //without this instrucion,items won't be loaded inside the second level of the table
[rvController release];
}
}
