In certain places such as Mail.app, the top navigation bar is thinner in landscape mode than in portrait mode. Does anyone know how I could get something like this in my own app?
This is the default behavior. What makes you think you're not getting this in your own app? You just need to override
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
in your view controller and return YES in all cases. The navigation bar (assuming you're using a UINavigationController) at the top will be thinner in landscape than in portrait by default.

I am trying to set up some views on the storyboard.
Now I am stuck with displaying the navigation bar in the correct way.
When the corresponding view opens (in Portrait mode) the Navigation Bar opens in Landscape Mode.
How can I set the navigationBar to stick with the screen Orientation and Size?
I am unsure what you mean, are you using the simulator or a Device ? Make sure you add constraints to pin the bar to the top of the view controller or embed your view controller in a navigation controller.
I am making a navigation based app and I need only portrait orientation except in a ZoomPictureViewController ( Zoom in, zoom out images) that supports all orientations.
I am presenting ZoomPictureViewController and returning YES in shouldAutorotateToInterfaceOrientation:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return YES;
}
But I get no rotation. I know that shouldAutorotateToInterfaceOrientation, willRotateToInterfaceOrientation, RotateToInterfaceOrientation are only get called on the current/visible view controller but this is not happening in my case. I have checked it via putting breakpoints and NSLog.
Are you using any type of Navigation Controller or a Tab View Controller? I've noticed that there are issues when rotating a UIView that's not the first or only view as a direct child of the main window.
So if your UIView is part of a Navigation Controller or a Tab View Controller, you'll also need to override shouldAutoRotateToInterfaceOrientation on the Navigation Controller or Tab View Controller.
Also I here's an important gotcha in the Apple documentation that might explain the problem you are having.
Tab bar controllers support a portrait
orientation by default and do not
rotate to a landscape orientation
unless all of the root view
controllers support such an
orientation. When a device orientation
change occurs, the tab bar controller
queries its array of view controllers.
If any one of them does not support
the orientation, the tab bar
controller does not change its
orientation.
I am trying to set a UIWindow in MainWindow.xib into landscape mode. Unfortunately, this option is greyed out in Interface Builder. I have a Navigation Controller within the same NIB that can be set to landscape, but this ends up looking awkward in Interface Builder, as the Nav Controller is set to landscape but the containing window is in portrait.
What's worse is that I can't get the window to run in landscape during runtime. I have this code in the view within the nav controller:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
I don't know how to specify this for the containing window though. I have set the orientation in the plist but this doesn't seem to make my view display in landscape.
From what i can see, it seems like you want your first view controller to be in landscape mode, when displayed.
For this, you need to set the "Initial orientation" in your info.plist file. There is a key for this.
Thus, what you need to do is, Make your xib in landscape mode, implement the method as you have done above and set the initial orientation to landscape in plist.
I faced a problem with the UIWindow being forced into portrait mode as well. My solution was to use another view level between the window and the views I was manipulating. Though not a perfect solution it worked. I hope you get it worked out.
I have an iPad application with a simple tab bar. I need to fix the orientation as portrait. I do that by setting "Portrait (bottom home button)" in the "Supported interface orientation" field in the plist file.
The problem is that the status bar still move when rotating the iPad... how can I fix it ??
Thanks for reading.
Remove the default implementation of shouldAutorotateToInterfaceOrientation: from all your view controllers.
All my app is in landscape mode .In some point I switch to a screen with Tab Bar Controller , but it's been placed like in portrait mode.I subclassed the UITabBarController and override the method "shouldAutorotateToInterfaceOrientation" to return YES always but because the app is already in landscape , this method is not being called.
does anyway have an answer to this?
thanks

You shouldn't have to subclass UITabBarController. The tab bar will autorotate to landscape, if all it's subviews support landscape. Just make sure all tabs support landscape orientation and you should be fine afaik.
Rengers is right, just make sure all tab views have YES in their respective shouldAutoRotateToInterfaceOrientation overrides. Depending on how you setup your app, check if any parent views have the shouldAutoRotateToInterfaceOrientation overrides. If so, it might be worthwhile commenting them out and leaving the overrides for the tab views only.
