iPad status bar covers up my app's top UIViews; okay after rotation

Question: What can I do in software (during the startup logic) to get the iPad to push my window down to make room for the status bar?

- (void)loadView {
 CGRect frame = CGRectMake(0, 20, 768, 1004);
 UIView *v = [[UIView alloc] initWithFrame:frame];
 self.view = v;
 [v release];
 NSLog(@"%s: self.view=%@ self.view.frame=%@",
 _func_, self.view, NSStringFromCGRect(self.view.frame));
}

I think the iPad should do it automatically for me

// MyAppDelegate.m
#import "MyAppDelegate.h"
#import "MyViewController.h"
@implementation MyAppDelegate
@synthesize window, viewController;
- (void)applicationDidFinishLaunching:(UIApplication *)application { 
 MyViewController *vc = [[MyViewController alloc] initWithNibName:nil bundle:nil];
 vc.view.backgroundColor = [UIColor grayColor];
 self.viewController = vc;
 [vc release];
 [window addSubview:viewController.view];
 [window makeKeyAndVisible];
 NSLog(@"%s: viewController.view.frame=%@",
 _func_, NSStringFromCGRect(viewController.view.frame));
}
- (void)dealloc {
 [viewController release];
 [window release];
 [super dealloc];
}
@end
// MyViewController.m
#import "MyViewController.h"
@implementation MyViewController
/*
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
}
*/
/*
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
 [super viewDidLoad];
}
*/
@end

... I'm using a coordinate of (0,0) for my upper left corner, which is correct

and after the first rotation everything works great.

Create a new iPad View based project called 'frame'.
Double click on frameViewController.xib to start IB.
Select View and examine its dimensions with the Size Inspector.

I think I love black boxes as much as the next OO fan boy.. but now and then it might be nice to know what the freaking controller is actually doing.

I"ve never been able to find out when it knows and when it doesn't

It depends on the 'Resize View from NIB' flag in the view controller attributes in the MainWindow.xib.

Hi David,

I may be new to all this but I'm busy writing iPhone/Pod/Pad Universal apps and have some experience in iPhone/iPod app development.

Can't you just switch the status bar off or use the application frame - thereby dodging the status bar completely?

1) [[UIApplicationsharedApplication] setStatusBarHidden: TRUE];

2) [selfsetWindow: [[UIWindowalloc] initWithFrame: [[UIScreenmainScreen] applicationFrame]]];

I use (1) followed by (2) in all of my iApps now and I've never had a problem.

Hope this helps.

The Resize View From NIB checkbox doesn't appear to be in Xcode4. Do you happen to know what the new recommended way is to achieve this same behaviour under Xcode4? I am still searching for it, but not having much luck so far.

Thanks

It's there in XCode4 for ViewControllers. Just click the attributes inspector.

Actually it isn't. I did look. I am using Xcode 4.0.2. The attributes inspector for both the view and the view controller does not have it.

I solved the problem this way. Fixes it if and when it is wrong.

- (void) viewWillAppear:(BOOL)animated

{

CGRect arect=[[UIScreenmainScreen]applicationFrame];

CGRect anotherrect=[[UIApplicationsharedApplication]statusBarFrame];

if(self.view.center.y==arect.size.height/2)

self.view.center=CGPointMake(self.view.center.x, self.view.center.y+anotherrect.size.height); // fix silliness in IB that makes view start 20 pixels higher than it should on iPhone
