I have an application in which I have apply facility to change orientation of view but when I change the orientation then go to next screen then there show a gap on right side if I rotate device in right side as show in image:
I use this code in viewcontroller.m:
-(void) viewWillAppear:(BOOL)animated{
UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];
[self willAnimateRotationToInterfaceOrientation:orientation duration:0];
}
-(void) willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
if(toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown )
{
lgo_imag.frame=CGRectMake(0, 0, 320, 44);
btn_settings.frame=CGRectMake(238, 3, 72, 37);
btn_alarm_activity.frame=CGRectMake(125, 10, 70, 85);
btn_alarm_screen.frame=CGRectMake(48, 210, 225, 55);
btn_routine_screen.frame=CGRectMake(48, 275, 225, 55);
btn_view_info.frame=CGRectMake(48, 340, 225, 55);
lable_alarm_value.frame=CGRectMake(25, 100, 270, 81);
scroll_view.frame=CGRectMake(0, 44, 320, 416);
scroll_view.contentSize=CGSizeMake(320 ,416);
}
else if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight )
{
lgo_imag.frame=CGRectMake(0, 0, 480, 44);
btn_settings.frame=CGRectMake(398, 3, 72, 37);

lable_alarm_value.frame=CGRectMake(125, 100, 270, 81);
scroll_view.frame=CGRectMake(0, 44, 480, 320);
scroll_view.contentSize=CGSizeMake(480 ,470);
}
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Overriden to allow any orientation.
return YES;
}
How fix that problem?
Add +20 to the view frame. This happens because its not including status bar space.
You can use the below property for AutoSizing the controls based on orientation. But be careful in using it, only change those controls property which you want to autosize.
EDIT
Please go through this link iPhone SDK: Orientation (Landscape and Portrait views) I think you are not putting your code in orientation changing method. This link will definitely guide you.
Use this method for orientation change detection..
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscape);
}

In portrait orientation, i have pushed the view contents up when keyboard appears and pushed it down on return key press.The view's frame is x=0, y=20 (status bar placed). In xib, the view size is set to freeform. When changed to landscape orientation, the new view's frame's origin is x=20 y=0. Ideally it should be x=0 and y=20 right? Below is the code.
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

if(toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)

I got the same issue in iOS7.
At the same time the same code works fine in iOS8.
To fix this issue you need to shift view.bounds instead of view.frame
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.

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.)
I want to set position of UILable programatically depend on orientation. But When I get back to Portrait, it doesn't work.
Here is my code :
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
if([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationPortrait || [[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationPortraitUpsideDown)
{
lblUserName.frame = CGRectMake(20, 200, 280, 44);
lblPassword.frame = CGRectMake(20, 246, 280, 44);
}
else
{
lblUserName.frame = CGRectMake(20, 220, 280, 44);
lblPassword.frame = CGRectMake(20, 266, 280, 44);
}
}
There are 2 possibilities.Either you can set the label programatically.And check the condition for orientation in the - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{}
method.Otherwise you can use auto resizing mask.
try with this IF condition:
if ( UIInterfaceOrientationIsPortrait(toInterfaceOrientation))
{
}
else {}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
//write code here
return YES;
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
//write code here
}
Use this two methods for set your label when rotate device.
I would like to know that what is difference between these both lines of code?
self.view.frame = CGRectMake(0, 0, 320, 480);
self.view.superview.frame = CGRectMake(0, 0, 800, 900);
and I want to change the view frame when my orientation will change, because it will change the position of labels, and I want them in middle of screen, can anyone guide me ?
I am using following delegate method, for orientation, but it is not working with
self.view.frame
but it is working ok with following line
self.view.superview.frame
See the following code
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
//return (interfaceOrientation == UIInterfaceOrientationPortrait);
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
NSLog(#"LEFT");
self.view.frame = CGRectMake(100, 0, 480, 320);
NSLog(#"Show self.view.frame: %#", NSStringFromCGRect(self.view.frame));
// self.view.superview.frame = CGRectMake(-50, -70, 800, 900);
[button setFrame:CGRectMake(340, 320, 100, 30)];
}
if (interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
NSLog(#"RIGHT");
self.view.frame = CGRectMake(0, 0, 320, 480);
NSLog(#"Show self.view.frame: %#", NSStringFromCGRect(self.view.frame));
//self.view.superview.frame = CGRectMake(10, 90, 800, 900); //It is working if I will uncomment it
[button setFrame:CGRectMake(250, 300, 100, 30)];
}
if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
self.view.frame = CGRectMake(0, 0, 320, 480);
//self.view.superview.frame = CGRectMake(0, 0, 800, 900);//It is working if I will uncomment it
[button setFrame:CGRectMake(250, 400, 100, 30)];
}
return YES;
}
self.view is the view of self (if we are talking about viewControllers).
self.view.superview is the view that is holding self.view.
So, in short, if you add a view to the window the superview of that view will be the window.
Setting the frame will fail if the autoresize mask isn't set correctly.
As a generic statement, the first line is trying set the frame of the current viewController's view that this code is written in.
The second line is trying to set the frame of the parent view of the view of the current viewController's view.
What this exactly means, and which one you should be using I'm afraid depends on the view hierarchy you have set up in your application.
My application goes back and forth between Portrait and Landscape. I have all of my content(labels, uiimageviews, uilabels) lined up to relocate for both orientations. However, the only change when the device is actually rotated. When I cycle between tabs after it has been rotated it just shows up autosized and not the way I have it setup when the user rotates it.
How can I detect the orientation of the device and display the view to reflect the orientation when the taps different tabs?
Ok, I set it to viewWillAppear. Is there a reason why it isn't detecting the orientation and displaying the content where I have set it?
-(void)viewWillAppear:(UIInterfaceOrientation)fromInterfaceOrientation duration:(NSTimeInterval)duration{
UIInterfaceOrientation toOrientation = self.interfaceOrientation;
[UIView beginAnimations:#"move buttons" context:nil];
[UIView setAnimationDuration:0.5f];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
if(toOrientation == UIInterfaceOrientationPortrait
|| toOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
aboutContent.frame = CGRectMake(20, 100, 280, 107);
myLogo.frame = CGRectMake(-5, 20, 330, 65);
bulletOne.frame = CGRectMake(40, 220, 240, 45);
bulletTwo.frame = CGRectMake(40, 270, 240, 45);
}
else
{
aboutContent.frame = CGRectMake(40, 80, 400, 70);
myLogo.frame = CGRectMake(230, 30, 20, 20);
bulletOne.frame = CGRectMake(90, 140, 330, 65);
bulletTwo.frame = CGRectMake(90, 170, 330, 65);
}
[UIView commitAnimations];
}
In each UIViewController's viewWillAppear check the device's orientation and if the orientation is different from how you have it layed out then send willRotateToInterfaceOrientation:duration: to self. That's assuming that your willRotateToInterfaceOrientation:duration: will update the layout to the specified orientation.
