So you have this splitview but you don’t want to show it all the time in landscape, but Apple never explained how to do that. Let’s make up on that:
First add some button logic in the app delegate:
– (IBAction)toggleSplitView:(id)sender {
if ( [window.subviews containsObject:splitViewController.view] ) {
[splitViewController.view removeFromSuperview];
splitViewController.viewControllers = [NSArray arrayWithObjects:leftViewController, leftViewController, nil];
[window addSubview:rightViewController.view];
[(UIBarButtonItem *)sender setTitle:@”Show Sidebar”];
} else {
[rightViewController.view removeFromSuperview];
[rightViewController.view setTransform:CGAffineTransformIdentity];
[navigationController popToRootViewControllerAnimated:NO]; // make sure we are on top
[navigationController setViewControllers:[NSArray arrayWithObject: leftViewController]];
splitViewController.viewControllers = [NSArray arrayWithObjects:navigationController, rightViewController, nil];
[window addSubview:splitViewController.view];
[rightViewController.view sizeToFit];
[(UIBarButtonItem *)sender setTitle:@”Hide Sidebar”];
}
}
In the controller that handles your right view (detail) add a item:
UIBarItem *toggleSidebar;
@property (nonatomic, retain) IBOutlet UIBarItem *toggleSidebar;
Insert the control when the controller is triggered during hide and show:
– (void)splitViewController: (UISplitViewController*)svc willShowViewController:(UIViewController *)aViewController invalidatingBarButtonItem:(UIBarButtonItem *)barButtonItem {
NSMutableArray *items = [[toolbar items] mutableCopy];
[items removeObjectAtIndex:0];
[items insertObject:toggleSidebar atIndex:0]; // add additional control for hiding
[toolbar setItems:items animated:YES];
[items release];
self.popoverController = nil;
}
Add a button in the load view that triggers the AppDelegate:
toggleSidebar = [[UIBarButtonItem alloc] initWithTitle:@”Hide sidebar”
style:UIBarButtonItemStyleBordered
target: [self appDelegate]
action:@selector(toggleSplitView:)];
And don’t forget to put in in the toolbar 🙂
[items insertObject:toggleSidebar atIndex:0];
// set the bar
[toolbar setItems:items animated:YES];
Oh and hide it in the willHideController
Dealoc it when done:
– (void)dealloc {
[popoverController release];
[toolbar release];
[toggleSidebar release];
[super dealloc];
}
