I have an iPhone Application, that uses a Navigation controller and TabBar controller.
In a first view, I show an a tableview, and when I click on first tableview cell, I set a new view with new Toolbar and without TabBar.
The new view correctly shows the toolbar, but this is far from 40px down, as if it were always leaving the seat to the previous TabBar.
In that regard, I saw that Interface Builder sets the size of the view in 320 x 460, and not with the classic 320 x 480. Unfortunately they are not editable fields (they are grayed out as if it were a lock). Why?

Set hidesBottomBarWhenPushed to TRUE before you push the view controller.
The 20px difference is the height of status bar. You can set if the view been shown with or without a status bar from the view's property pane of IB.
If you are using interface builder, try placing the toolbar at the bottom of the view and adjust the stud to keep it at the bottom(turn on the bottom stud on), this will help surely.

I have started an app using story board.
In that i have used tabbar controller
In a view, I have Table view in that having a custom cell, And I have added a search bar at the top of the Table view. as shown bellow
The problem is when I add Search bar very close to the navigation bar, It does not display and if i added little down it was displayed
what was the issue is in 2px difference?
Go to IB Inspector
Select search bar and set AutoSizing Mask like this attached Picture.. Enable left, right, top and center position.
I've added a tab bar controller to my app delegate. In IB, I adjusted the alpha property and unchecked opaque, however in the simulator I get transparency over a white background, even though there should be content below it.
Perhaps, the containing View needs to be resized to the full dimensions of the screen? I'm using a nav controller with a tableview in this tab bar item.
What? You want your UITabBar to be translucent? A UITabBar is not a subclass of UINavigationBar, therefore the content from any view controllers the tab controller manages will not appear under the tab bar, if that's what you're trying to do.
Is it a Segmented Control?
About the featured view, is it purely a tableview? how could they make the Segmented Control to be permanent instead of scrolling with the table cells down below?
as Ertebolle says its a UISegmentedControl set as the titleView of the navigationItem.
You can also create elements within the view that don't scroll with the tableview by adding a UITableView as a subview of a UIViewController's view. Setting its frame property means that you can have a scrollable tableview in a fixed certain position in your view and other elements in the view that don't scroll with it.
Yes, I believe it is a UISegmentedControl. But it's set as the title view of the navigation bar - to reproduce the whole effect, you'd create a UINavigationController, push a UITableViewController as the top view in it, and set the titleView of the table view controller's navigationItem to that segmented control. This would automatically anchor the toolbar / segmented control on top.
I hope to display the view of one of ViewControllers in my app as full screen , so in Interface Builder, I set the statusbar as None.
I also resize the frame of view as 320*480
but when I run the app, the view of the viewcontroller still displays the statusbar.
Welcome any comment
thanks
Call setStatusBarHidden:withAnimation: on [UIApplication sharedApplication].
it is not diffult to solve the problem. In your project setting plist file, check the key"Status bar is initially hidden", status bar will be removed from startup.
You need to set your view controller's wantsFullScreenLayout to YES. Make your xib file as big as the screen and set this in your viewDidLoad.
wantsFullScreenLayout
A Boolean value indicating whether the view should underlap the status
bar.
#property(nonatomic, assign) BOOL wantsFullScreenLayout
Discussion
When a view controller presents its view, it normally shrinks that
view so that its frame does not overlap the device’s status bar.
Setting this property to YES causes the view controller to size its
view so that it fills the entire screen, including the area under the
status bar. (Of course, for this to happen, the window hosting the
view controller must itself be sized to fill the entire screen,
including the area underneath the status bar.) You would typically set
this property to YES in cases where you have a translucent status bar
and want your view’s content to be visible behind that view.
If this property is YES, the view is not resized in a way that would
cause it to underlap a tab bar but is resized to underlap translucent
toolbars. Regardless of the value of this property, navigation
controllers always allow views to underlap translucent navigation
bars.
The default value of this property is NO, which causes the view to be
laid out so it does not underlap the status bar.
Availability Available in iOS 3.0 and later.

I have a view with tab bar at the bottom. This view is pushed on a navigation controller, so there is also a navigation bar at the top. Unto this view, I would like to show a table view, which I create from its own nib. When I add this view as a subview, it overlaps the tab bar.
Is there a way to make this subview automatically resize to the free space in between the top and bottom bar?
If not, what is the 'right' way of adjusting its size to fit?

In the interface builder make sure that you've set the navigation bar and tab bar spacers up. It should be the first list of options on the first tab in the Interface builder Properties view. This will make your view mimic the amount of space it has when loaded in the view.
From there you can also choose the option to clip the subview. The interface builder also allows you to set resize options for the view. If the subview your adding wasn't created in the interface builder you'll have to specify those options manually.
Lastly make sure that your appending the subview to the correct view, and not the tab bar controller or navigation controller.
Best bet is to make sure the subview your addings dimensions are appropriate for the amount of space you have by creating a frame using CGRect.
