In the iPhone maps app there's a toolbar at the bottom of the map view (it contains the Search/Directions segment control and others). When moving from the map view by clicking on a callout, the toolbar slides out with the map view, leaving the next view (a table controller) with no toolbar.
I've tried to do the same thing with [self.navigationController setToolbarHidden:YES animated:YES] in the second view controller, but this gives a strange toolbar sliding down animation, while the map view is sliding to the left.
Using [self.navigationController setToolbarHidden:YES] in viewDidLoad also causes a bad effect (it makes the toolbar disappear the moment the push animation starts, leaving an ugly white space).
I'm assuming the answer to this is to use a nib file, but I'd prefer to do it programatically (if possible).
How can I get the toolbar to "stick" to the map view and slide out with it when I push a new view controller? Thanks.

It turns out the answer is to create the toolbar directly and add it to the view yourself. This is in the code for a UIViewController with a UINavigationController. The frame coordinates can change according to what is on screen.
- (void)viewDidLoad
{
// Add a toolbar to the view
CGRect toolbarFrame = CGRectMake(0, 372, 320, 44);
UIToolbar *myToolbar = [[UIToolbar alloc] initWithFrame:toolbarFrame];
UIBarButtonItem *compassButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"compass.png"]
style:UIBarButtonItemStyleBordered
target:self
action:#selector(zoomToCurrentLocation)];
compassButton.width = 30.0f; // make the button a square shape
[myToolbar setItems:[NSArray arrayWithObject:compassButton] animated:NO];
[compassButton release];
[self.view addSubview:myToolbar];
[super viewDidLoad];
}
I was around this for a day once. Really dont get the programatically answer, but the best way to views to behave correctly, is to do the interface in the interface builder. If you set items for a toolbar in your code like:
[self.navigationController setToolbarItems: control1, control2,..., nil] animated: NO];
with my little experience, I can say that you are saying to the entire application to have a toolbar present when you push new views unless you hide it (or you are using a tabBar), but hiding it you get those unwanted effects.
You can try this:
[self.navigationController setToolbarHidden:YES animated:YES];
in your first controller - (void)viewWillDisappear:(BOOL)animated method,
and setting hidden to NO in - (void)viewWillAppear:(BOOL)animated method in the first controller too.
Hope this helps.
PS: And if you get the programatically answer, let me know! =P
Override the second view controller's -viewWillAppear: method to hide the toolbar.

I have a uitableview inside and uiview which is being presented in a navigation view (so it has a navigation menu). Under the navigation menu I have a uitoolbar appearing when the view loads and disappearing when the load is poped from the navigation stack.
The issue I am having with this is that when I animate this view onto the stack with normal animation transition right to left, the tableview dose not do this it just appears quickly before the view is finishe sliding into view. Then when you select the back button and the view begins to animate from left to right it dissipears before the end of the animation again.
I would like to know how to get this toolbar to animate with the rest of the view, right to left, left to right etc instead off appearing over the sliding effect abnormally.
This is how I call and dissmiss the toolbar at the moment.
- (void) viewWillAppear:(BOOL)animated
{
[self.navigationController setToolbarHidden:NO animated:NO];
[self.navigationController.toolbar setFrame:CGRectMake(0, 60, 320, 30)];
self.navigationController.toolbar.tintColor = [UIColor darkGrayColor];
[SeriesTableView setFrame:CGRectMake(0, 30, self.view.frame.size.width, self.view.frame.size.height)];
[super viewWillAppear:animated];
}
- (void)viewWillDisappear:(BOOL)animated
{
[self.navigationController setToolbarHidden:YES animated:NO];
[super viewWillDisappear:animated];
}
which is pretty much the standard way of doing things.
Any help would be greatly appreciated.
The toolbar property of the navigation controller is already onscreen, but is hidden from view. If you want a toolbar to animate on and off with a certain view, add the toolbar to that view. Then the toolbar will animate on and off as part of the view.
I have a viewController and I am trying to add a subview to it such that it will cover the whole screen, however this has a navigationController in it so that adding a subView always adds it below the navigation bar, is there a way to simulate a presentModalViewController in cases like this?
You can add the subview to the view controller and then hide the navigation controller from the top or you could still push it to the navigation controller and then just remove the navigation controller from the top again and then you could use pop to go back and forth.
the code to push a view controller is
if(!self.YOURVIEWCONTROLLER){
self.YOURVIEWCONTROLLER = [[YOURVIEWCONTROLLER alloc] initWithNibName:#"YOURVIEWCONTROLLER" bundle:nil] autorelease];
}
[self.navigationController pushViewController:self.YOURVIEWCONTROLLER animatedLYES];
and on the next NEXTView.m add
[self.navigationController setNavigationBarHidden:YES];
remember to create an instance of YOURVIEWCONTROLLER in the .h file. Or you could do a simple
[self.view addSubview:NEWVIEW];
[self.navigationController setNavigationBarHidden:YES];
at least at bear minimum the line for making the navigationController hide is there.
I seem to recall once having a similar problem, and I seem to recall the solution was to add the subview to the navigation controller (as the view controller is already a sub view of the navigation controller) rather than adding it to the view controller.
I recently have similar problems and after spending 5 to 10 min I get the exact solution...
According to my solution I simply add my custom UIView to subview of navigationController.view
Like This :-
[self.navigationController.view addSubview:popOver];
popOver - Your custom UIView
Happy Codding :)
Add the view to the superview of the navigationController's view.
[navigationController.view.superview addSubview:viewController.view];
Perhaps you could hide the navigation bar when you add the subview. I have a method on my ViewController that looks like this:
self.navigationController.navigationBarHidden = YES;
UIView *v = [[UIView alloc] initWithFrame:self.view.frame];
v.backgroundColor = [UIColor redColor];
[self.view addSubview:v];
When that code executes, my navigation bar disappears and a full screen red view replaces it.
I want to display a UIViewController as a small popover over an other UIViewController.
The UIViewController should be display modal, but not take the whole screen.
It should just show up on a lower third of the screen...
Can somebody point me to a tutorial or give me some hints to start on this?
I googled for over one hour, but could not find anything, that helps me :(
Thanks for your help,
Stefan
Just discovered that this question is still unanswered ... You have multiple options to achieve such a thing running on iPhone:
Depending on the situation, I think I would just go with a UIViewController subclass loading from a NIB that you configured to show a screen-sized view with the backgroundColor property set to [UIColor clearColor]. Add whatever subviews you want to display as a popover to that view at the position you want (e.g. lower third of screen). You can then present the view controller modally with the UIModalTransitionStyleCrossDissolve to fade it in and even use the background view to intercept touch events to dismiss the modal view.
Another possibility would be to just add the popover's view controller's view as a subview to the main view controller's view. You can use UIView's animation class methods to animate the transition.
this might help.
you have to declare popOverController in the header and make it a property as well as synthesize it.
if([self.popOverController isPopoverVisible])
{
[self.popOverController dismissPopoverAnimated:YES];
return;
}
UINavigationController *favNav = [[UINavigationController alloc]
initWithRootViewController:favoritesView];
//favoritesView is an outlet to the VC Favorites
//make a nav controller with the root view an outlet to the view you want to present.
self.popOverController = [[[UIPopoverController alloc]
initWithContentViewController:favNav] autorelease];
[popOverController presentPopoverFromBarButtonItem:revealFavorites permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; //revealFavorites is the button i press to show the favorites popover
favoritesView.view.frame = CGRectMake(10, 10, 310, 320); //set the frame
if (![self.popOverController isPopoverVisible]) {
[favNav release];
}
}
I am trying to show the UIToolBar in the RootView of a UISplitView application, the code is the following:
self.navigationController.toolbarHidden = NO;
UIBarButtonItem *refreshItem = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
target:self
action:#selector(refresh:)];
self.toolbarItems = [NSArray arrayWithObjects:refreshItem, nil];
[refreshItem release];
However, what I see is:
There's black bar on top (I don't know where this came from, I don't need this) also the bar at the bottom, is there a way to resize it?
What I want is to get something like this:
Using something like this you can add a bar button item to the top of the controller:
UIBarButtonItem *refreshItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refresh:)];
self.navigationItem.leftBarButtonItem = refreshItem;
[refreshItem release];
You will make the button appear in the main view controller's title bar, as it's meant to be.
If you want to make the button appear in the bottom of the navigation controller you could try using this approach, instead:
UIBarButtonItem *refreshItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refresh:)];
[self setToolbarItems:[NSArray arrayWithObjects:refreshItem, nil animated:YES]];
[self.navigationController setToolbarHidden:NO]; //optional, don't remember if it's required ...
[refreshItem release];
For this piece of code to work correctly the side controller has to be a UINavigationController, otherwise you wouldn't be able to create and handle the toolbar. I tried this approach in a clean project and the toolbar renders perfectly.
I had the same issue and Just fixed it, Due to moving the code out of the Viewdid Load to lower down the Page,
As I had previous put in
- (UIBarButtonItem *)barButtonItem {
Moving the Code You used to under that, Worked and fixed the issue

Just a note for anybody else who stumbles upon this question. I was having the same issue as adit. The problem turned out to be I was setting up and unhiding the toolbar in the viewDidLoad method instead of the viewWillAppear method. Those gaps are caused by setting up the toolbar before the view knows it's being displayed in landscape mode.
The safest and easiest solution is to setup the UINavigationController to display the toolbar and navigation bar in Interface Builder.
If it looks as expected in IB, it is very unlikely it will change at run-time.
If the toolbar is to be shown/hidden when navigating you should add the cod to do so in viewWillAppear: and allways call the super implementation, or unexpected things may occurs. Something like this tends to give the best results in a consistent manner:
-(void)viewWillAppear:(BOOL)animated;
{
[super viewWillApplear:animated];
[self.navigationController setToolbarHidden:NO
animated:animated];
}
Also make sure to show/hide the toolbar as need in viewWillAppear: for all view controllers in your navigation stack for best result.
I need to replace a view with another view (getting rid of the first view), but all I know are modal views. How do I do this?
// In a controller method
[oldView removeFromSuperview];
[self.view addSubview:newView];
A couple different options..
One way is to add a view to your current view. This doesn't "get rid" of your orginal view but it does make it not visible if the new view is in front.
Code would look something like this.
newView = [[NewViewController alloc] initWithNibName:#"NewViewController" bundle:nil];
newView.view.frame = CGRectMake(x,y, newView.view.frame.size.width, newView.view.frame.size.height);
[newView SetMessage:#"my message"]; // set some data for the new view.
[self.view addSubview:newView.view ]; // show new view
Then the new view controller can close itself or just hide itself.
