I am trying to set up a Modal View Controller, that that lies below a fixed toolbar. therefore the toolbar is supposed to stay on top while the modal view rolls in.
the Safari-App does that for example, when hitting the bookmarks-button. the toolbar stays, the buttons change..
I tried a couple of things like pushing the toolbar to the front and ended up not using the presentModalViewController method at all, and animating the new View manually into a subview instead. but that brought a couple of other issues along.
I'm not sure what you are saying, when you press add bookmark in safari, a new modal view shows with no tool bar. The navigation bar at the top is not a tool bar if that is what you mean. They are UIToolbarItem set into self.navigationItem.
All modal views I've seen are animated until they take up the whole of the screen. Those modal-like views that only scroll up to a certain point in some apps, are done by hand. Maybe you can cover those issues encountered when doing this by hand in another post?

I would like to develop a ipad apps which has a menu at the top of the screen as well as at the bottom.
There are four buttons on the top of the screen, and there are 10+ buttons at the bottom tab bar, which can be scrolled horizontally.
How can I write the root view controller as a framework for this operation?
Should I customize the UIViewController class or UITabBarViewController?
Thanks
EDIT:
Sorry for being unclear. Let me restate my question.
Actually my app will have the following hierarchy.
'Front Page' is simply a page (view controller) for user to choose language. After choosing the language, 'Menu Page' view controller is displayed.
Starting from Menu page and ALL view controllers (VC) in below, the page layout is something like this.
As you can see, there are top menu and bottom menu. Clicking on the buttons the app will quickly jump to the corresponding view controller (3rd level in the tree, VC1,VC2,VC3 etc) . And for every view, there is a BACK button on every page, clicking which will back to the parent view controller.
I was thinking to implement this by using a tab bar view controller and a navigation view controller but I still do not have a clear idea how to implement this.
Or maybe should I just use the navigation view controller and hide the top tool bar except the back button, and display an overlay UIView as menu which is on top of all other UIViews.
Can somebody help me? Thanks.
Since this is the outermost container for my app I hope to do it properly at start..
Sorry for my long question.
If you really want to develop a framework for this logic .You need to create Manager, ViewController, View, DAO ,Model and other classes according to your needs.
I assume you want to add the buttons dynamically to the tabbar (and if it scrollable , it must be a scrollview).You can use Toolbar for upper view but then it won't be in sync with the bottom-view(visually).In that case you will have to create your own customized views to look like a tabbar.
The manager will basically keep a track of all the buttons and different states of events and action on the views and the same information can be accessed via a static method form the viewcontroller.
Well you have not detailed on your needs , so it's difficult to predict the entire architecture.
You need a container view controller to manage selection of VC's 1-4.
clicking which will back to the parent view controller
Parent view controller is used to mean the container vc in a container view controller scheme - I'm not sure that's what you mean in this comment. Where exactly does the back button go?
See this link for more info about container VC's.
https://developer.apple.com/library/ios/featuredarticles/ViewControllerPGforiPhoneOS/CreatingCustomContainerViewControllers/CreatingCustomContainerViewControllers.html
You should be able to embed a tab bar controller in the content view of the container VC. Should be able to but it might be really buggy if there is a lot of communication between the child vc's.
The hard part is the back button. Basically it must be a button that goes back to VC 1-4 depending on which section you are in. The easiest way to do it is to make sure that when you cycle view controllers, pass the back button information as to which VC is the current child so it knows which VC to navigate to when you press it.
I am trying to show a modal view controller that hovers over another viewcontroller. Now the problem is when I use pushViewControllerAnimated the view controller that gets pushed will be as big as the whole iphone screen. I just want it to be half size of the screen.
How to adjust the size?
What exactly do you mean by half size of the screen?

Read http://devblog.bu.mp/easy-partial-screen-modals-on-ios if you really have to use an UIViewController for that, which is not recommended by Apple (http://blog.carbonfive.com/2011/03/09/abusing-uiviewcontrollers/)
Hope this helps.
I'm aware some of you may not be familiar with Monotouch, but this could certainly be a general iOS issue rather than a specific Monotouch issue.
I'm recreating an app with similar functionality to the default mail app:
This is a simple recreation of our app. It's a UIView which contains a UITableView and a UIToolbar. It's loaded from a XIB file (which contains accompanying view controller code). This view is a UITabController view (though I'm sure this shouldnt affect things?).
This has been pushed from a navigation Controller using
controller.PushViewController(inboxItem.Controller, true);
(where inboxItem is a custom object I've made, the Controller property being the inboxItem's view controller).
Pressing the right hand button on the toolbar presents a new modal view (compose new message) - which does its thing and no matter which way its dismissed, upon dismissal, the UIToolbar disappears. However, if I am to click on another tab then click back onto this tab, the Toolbar reappears. Is this a redraw issue?
Am I doing something wrong with the way I'm structuring my app? Or have I happened to stumble across some bizarre iOS/Monotouch bug? (I'm hoping it's for the former - so I can improve my iOS development).
I solved the problem. Basically, what was happening was when the ModalView was being presented and then dismissed, the toolBar was being moved down by 44 pixels each time.
In my example, the toolBar is placed above a UITabBar, so when the modal view was dismissed the toolbar was being moved out of view. I'm not sure why this is happening but I'll be sure to file appropriate bug reports.
One quick and (very) dirty way around this is to move the toolBar up 44 pixels when displaying the modalview, so that when it is dismissed, it will move it back down to the appropriate position.
I posted earlier but am running into similar problems again. Basically the way that my app is setup there is a top bar that is basically just a static image that has UIButtons placed on top of it. That is the Main View Controller and is persistent no matter what view is shown beneath it. I can't use a navigation controller because it is not possible to change the height and I need the bar to be significantly larger than a navbar. However my bar is functioning in much the same way. There is a "Home" Button, a "Back" Button and several destination buttons.
I understand how to switch views from say the home screen. My confusion comes with the back button. In order to press back the app is going to need to know what view is currently being displayed so that it can be removed from view and a new subview can be added. Ideally I would use the UINavigationController so that I can push and pop views which is really what I want to do here, however that is not possible because of the visual problem.
Does anybody know of a method that returns the current displayed view so I could do something like the following
[currentview.view removeFromSuperView];
[self.view insertSubview:experienceViewController.view atIndex:0]
You can use UINavigationController with the nav bar hidden. Put the nav controller inside a view that does have your jumbo toolbar and you'll have access to the push/pop behavior you're looking for.
Hey everyone, running into a bit of an issue,
I have created all my views through IB, with the main window having a NavigationController, and a TabBarController which loads a TableViewController in its first tab.
The problem happens when i use the searchbarcontroller in the navigation controller, everything works fine with the exception that when the navigation bar at the top disappears, the table expands too high, and i can't figure out what im doing wrong.
Attached is an image of what im referring to, any help would be greatly appreciated.

Some more information:
i have my MainWindow with a UINavigationController, and a UITabBarController. On the first Tab, i have it loading another nib "AVN_TableController" which is a UITableViewController nib, with the Searchbar delegate.
If you've set your view sizes correctly in Interface Builder and are using the "Simulated Interface Elements" to cause the status bar, navigation bar, and tab bar to display, it should work correctly. If not, then what comes to mind is this issue where displaying an action sheet has it's tappable rectangle offset by the height of the tab bar because it is added to the wrong view. Not sure if that would apply here, but it's at least something to consider.
I ended up going the route of creating my own tabbarcontroller, as that was causing the issue.
