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;
