Device Orientation in iphone sdk - iphone

Question

i have a requirnmant for ipad to show contents both in landscape and portrait..so i have done the code and done the postions of controlles in each orientations.it works fine..my code is
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation == UIInterfaceOrientationLandscapeRight ||interfaceOrientation == UIInterfaceOrientationLandscapeLeft ) {
_viewContainer.frame = CGRectMake(342, 1, 681, 707);
_viewtopic.frame = CGRectMake(1, 62, 343, 56);
_viewpublicspeekingheaderleft.frame = CGRectMake(0, 6, 341, 58);
_viewTableview.frame = CGRectMake(1, 118, 341, 590);
_viewFooter.frame = CGRectMake(1, 716, 1024, 48);
if (interfaceOrientation == UIInterfaceOrientationPortrait ||interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ) {
_viewContainer.frame = CGRectMake(276, 1, 503, 946);
_viewtopic.frame = CGRectMake(0, 58, 275, 50);
_viewpublicspeekingheaderleft.frame = CGRectMake(0, 1, 275, 58);
_viewTableview.frame = CGRectMake(1, 109, 274, 837);
_viewFooter.frame = CGRectMake(1, 954, 767, 48);
}
return YES;
}
the above code works fine for me,i got alla the controllers in corect postions..here is my probm,,i have to set a timer to show full screen and i need to hide some controlers in the viewcontroller,,i had done the timer set to 3 second and after 3 second it hides some controlles and arrange the othe controlers in the view controller to show the ful sceen.it also works fine for me.my code fo this is
- (void)viewDidLoad
{
[super viewDidLoad];
// Define the timer object
NSTimer *timer;
// Create the timer object
timer = [NSTimer scheduledTimerWithTimeInterval:3.0 target:self
selector:#selector(updateorientation:) userInfo:nil repeats:NO];
}
- (void) updateorientation:(NSTimer *)incomingTimer
{
_tableTopic.hidden =YES;
_viewtopic.hidden =YES;
_viewpublicspeekingheaderleft.hidden =YES;
_viewTableview.hidden =YES;
_imgpulbicspeakingabovethetableview.hidden =YES;
_topiclabel.hidden =YES;
_lblpublicspeekingleft.hidden =YES;
UIInterfaceOrientation orientation =[[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIDeviceOrientationPortrait || orientation == UIDeviceOrientationPortraitUpsideDown ) {
NSLog(#"portrait");// only works after a rotation, not on loading app
_imgMicimage.frame = CGRectMake(69, 130, 635, 216);
_txtContentofTopic.frame = CGRectMake(69, 354, 635, 203);
_viewContainer.frame = CGRectMake(0, 0, 768, 1024);
}
UIInterfaceOrientation orientationLandscape =[[UIApplication sharedApplication] statusBarOrientation];
if (orientationLandscape == UIDeviceOrientationLandscapeLeft || orientationLandscape == UIDeviceOrientationLandscapeRight ) {
NSLog(#"landscape");
_imgMicimage.frame = CGRectMake(93, 113, 836, 239);
_txtContentofTopic.frame = CGRectMake(93, 360, 836, 203);
_viewContainer.frame = CGRectMake(0, 0, 1024, 768);
}
}
it works fine,but after the timer fires ,then i chnage the orientation of the device ,i only get the arrangmnts in the - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { function.i need the arrangmnts in the time function.how to solve this.
thanks in advance.

Answer 1

You should not be doing this work in -shouldAutorotateToInterfaceOrientation:. That method is simply to determine whether your UI should rotate (and will soon be superceded by a new system). You should use these methods to lay out your UI in reaction to an actual rotation:
-willRotateToInterfaceOrientation:duration:
-willAnimateRotationToInterfaceOrientation:duration:
-didRotateFromInterfaceOrientation:
Please see the UIViewController docs for more on those.
On iOS 5, -viewWillLayoutSubviews might be another good choice. (It will be called even if your controller's view isn't currently visible.)
