UIToolbar lost in rotation to landscape

turbolag · February 2009

I am writing an app with navigationBar, tableView, and toolBar programatically. I want the app to work in landscape and portrait mode. Below is my loadView method:

	//Add the table view			//initWithFrame:CGRectMake(0.0f, 44.0f, 320.0f, 436.0f) ];
	UITableView *tableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain];
	tableView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);
	tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
	tableView.delegate = self;
	tableView.dataSource = self;
	
	self.view = tableView;
	//[self.navigationController.view addSubview:tableView];
	
	[tableView release];
	
	//Initialize the toolbar
	toolbar = [[UIToolbar alloc] init];
	toolbar.barStyle = UIBarStyleDefault;
	
	//Set the toolbar to fit the width of the app.
	[toolbar sizeToFit];
	
	//Caclulate the height of the toolbar
	CGFloat toolbarHeight = [toolbar frame].size.height;
	
	//Get the bounds of the parent view
	CGRect rootViewBounds = self.parentViewController.view.bounds;
	
	//Get the height of the parent view.
	CGFloat rootViewHeight = CGRectGetHeight(rootViewBounds);
	
	//Get the width of the parent view,
	CGFloat rootViewWidth = CGRectGetWidth(rootViewBounds);
	
	//Create a rectangle for the toolbar
	CGRect rectArea = CGRectMake(0, rootViewHeight - toolbarHeight, rootViewWidth, toolbarHeight);
	
	//Reposition and resize the receiver
	[toolbar setFrame:rectArea];
	
	//Add the toolbar as a subview to the navigation controller.
	[self.navigationController.view addSubview:toolbar];

The problems are twofold:
1. The toolbar is pushed off the screen when in landscape mode
2. The toolbar covers the last row of the tableview in portrait

If I hardcode the frame of the tableview, it does not rotate properly. If I add the tableview as a subview to the navigationController.view, I see two tableviews overlaid in landscape mode.

How can I get both the tableview and toolbar to rotate and scale properly? Thanks in advance.

OK, I addressed the transitions from and to landscape by implementing the following method:

- (void) willAnimateSecondHalfOfRotationFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
														duration:(NSTimeInterval)duration{
	
	UIInterfaceOrientation toInterfaceOrientation = self.interfaceOrientation;
	
	
	if (toInterfaceOrientation == UIInterfaceOrientationPortrait){
		self.tableView.frame = CGRectMake(0.0, 0.0, 320.0, 372.0);
		toolbar.frame = CGRectMake(0.0, 480.0-64.0, 320.0, 44.0);
		//NSLog(@\"Portrait\");
	}
	else {//(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft||UIInterfaceOrientationLandscapeRight){
		self.tableView.frame = CGRectMake(0.0, 0.0, 480.0, 236.0);
		toolbar.frame = CGRectMake(0.0, 268.0, 480.0, 32.0);
		//NSLog(@\"Landscape\");
	}
}

This successfully positions the toolbar and tableview so they dont overlap. However, at startup the toolbar covers the last cell in the tableview, but when I transitition to landscape, then back to portrait, it is corrected!

I have changed the frame of the tableview in loadview to CGRectMake(0.0, 0.0, 480.0, 236.0), but it doesnt help. How could I correct this?
