issues with Xcode 4.5 while changing iPad's orientation - iphone

Question

Am facing this problem ever since i upgraded to XCODE 4.5.
I have various UI elements
UIButton *button1;
UIButton *button2;
UIButton *button3;
- (void)viewDidLoad
{
button1 =[[UIButton alloc]init ];
button1.backgroundColor=[UIColor yellowColor];
[self.view addSubview:button1];
button2 =[[UIButton alloc]init ];
button2.backgroundColor=[UIColor yellowColor];
[self.view addSubview:button2];
button3 =[[UIButton alloc]init ];
button3.backgroundColor=[UIColor yellowColor];
[self.view addSubview:button3];
}
whose frames are declared in
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if(interfaceOrientation==UIInterfaceOrientationPortrait ||[interfaceOrientation==UIInterfaceOrientationPortraitUpsideDown )
{
button1.frame=CGRectMake(10,10,10,10);
button2.frame=CGRectMake(10,30,10,10);
button3.frame=CGRectMake(10,50,10,10);
}
if(interfaceOrientation ==UIInterfaceOrientationLandscapeLeft ||interfaceOrientation==UIInterfaceOrientationLandscapeRight)
{
button1.frame=CGRectMake(20,10,10,10);
button2.frame=CGRectMake(20,30,10,10);
button3.frame=CGRectMake(20,50,10,10);
}
return YES;
}
but the frames are not set in Xcode 4.5..
in the previous versions it worked fine.
i need auto sizing badly in my app. so help me.

Answer 1

You should need to implement new methods(introduced in 'ios 6' ) in viewController for orientation
- (BOOL)shouldAutorotate
{
return TRUE;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
And Modify You Code place your code inside the in Below Method
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation duration:(NSTimeInterval)duration
{
}
Also check your window, you need to add the controller on window as rootviewController rather than addSubview like below
self.window.rootViewController=viewController;

Answer 2

Some classes will automatically resize when the device orientation changes, e.g. from portrait to landscape, but others (like UILabel and UITextView) require a little configuration.
The setAutoresizesSubviews property controls whether each object will resize automatically when their bounds change.
The setAutoresizingMask property controls how each object resizes automatically. A UILabel only has to worry about resizing its width, but since a UITextView is scrollable it needs to resize both its width and height when its bounds change.
You should also make sure the shouldAutorotateToInterfaceOrientation method is configured to return YES; otherwise your view won’t do anything when the device orientation changes!
Sample Code:
[self.myLabel setAutoresizesSubviews:YES];
[self.myLabel setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
[self.myTextView setAutoresizesSubviews:YES];
[self.myTextView setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight];
