I want to rotate my iphone application in ipad if I rotate the ipad
what I use in my code is :
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
{
return (orientation == UIInterfaceOrientationMaskAll);
}
and I check both portrait and landscape:
and the plist file:
my application device family is only iphone, and appears as an iphone in ipad device
But it doesn't rotate, please correct my code above, thank you
you ask it ? ;
if ([[UIDevice currentDevice] userInterfaceIdiom]==UIUserInterfaceIdiomPhone) {
}
Put it into the code if try again.
In the .plist file you only specify your startup orientations. After that every view controller can implement shouldAutorotateToInterfaceOrientation: in which the view controller is "asked" if a rotation to another orientation is acceptable. In the standard template for iPad apps this always returns YES and thus allows all orientations. In your case you might only return YES when the given orientation is UIInterfaceOrientationLandscapeLeft, although you should have a look if you can support both landscape orientations as Apple human interface guidelines strongly suggest to at least support both landscape orientations if one is supported.
Note that every view controller in your app has to specify its own orientations as it may make sense to have some views more restricted than others.
For further information on this have a look at:

I am planning to allow user to rotate the devices however during launch, i want the app start from landscape mode. May i know how can i do that?
Here is my code now for the orientation
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
} else {
return YES;
}
}
You need to check the orientation of the status bar.
Please check the following links :-
Force iOS app to launch in landscape mode
Modal View Controller force Landscape orientation in iOS 6
Force Landscape Orientation on iOS 6 in Objective-C
In the Project settings/target settings (the blue icon towards the top of the navigation bar on the left, in xcode), there are settings for specifying the orientation. You'll see 4 images, each of which can be selected or deselected.
Select only the one that you want initially for your app, and then you can use the shouldAutorotate and supportedInterfaceOrientation methods to allow or disallow certain orientations.
Supported interface orientations are also specified in the plist. Makes sure to keep the initial orientation for the app at the top of that supoortedInterfaceOrientations list in the plist file.
How can i make my app to be always in portrait mode only. If i rotate iPhone it should not display app in landscape mode.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation != UIInterfaceOrientationPortrait);
return YES;
}
After this coding when i rotate iPhone app is displayed in landscape mode. How can i make app to be in portrait mode all the time.
Remove the method — you don't need it. An iPhone app always starts in portrait mode unless you force it to start in landscape mode. If this method is absent, it will stay in portrait mode, as it effectively means "My view won't respond to interface orientation changes."
Incidentally, this method actually starts out commented out in Xcode's view controller templates, which is the same as it not being there at all.
In xcode click left top on your project name and then right below of "TARGETS" you can set "Supported Device Orientations".
Seems for iOS 6 you need to override this method,
-(BOOL)shouldAutorotate {
return NO;
}
How to change a UIImageView into landscapemode?
I have a UIImageview.whe it rotated its still in potrait mode.
code:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
Depending on the class/controller that is holding the view and it's inherited classes, it is likely that one of these is set to only allow portrait rotations.
Please check this and then provide us with more information so that we may advise you better, if what I have said is not the case.
If you only want your app to run in landscape and NOT allow portrait, update the 'Supported interface orientations' list in your app's info.plist to only include the landscape orientations.
I want my iPad app to stop rotation as you rotate the iPad. I want to stop rotate every view.
Any ideas help?
if you want stop rotation for whole app then simply in app info.plist file changed Supported interface orientations ,Initial interface orientation property to portrait or landscape depends on you
In iOS6 shouldAutorotateToInterfaceOrientation has be deprecated. Override both supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation instead.
Please see
Just check the auto-resizing property of your view controller.
(Fixed syntax error)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if(interfaceOrientation == UIInterfaceOrientationPortrait)
return YES;
return NO;
}
In My Project's info.plist I have deleted some key on the iPad Supported interface orientations like the following image (I have only given support for the portrait orientation)
The main idea of global controllable rotation lock is to write UIViewController category containing lock mechanism for every view controller.
You simply need to modify supportedInterfaceOrientations method globally
- (NSUInteger)supportedInterfaceOrientations
{
return __orientation;
}
Here __orientation is the static variable which can be set via category method.
The full realization of the category is presented here
Please update your projectname.plist like this. Supported interface orientations have only one object "Portrait (bottom home button)"
I strongly advise against stop rotation on iPad because supporting rotation is a must on the iPad. This is because the iPad does not have a normal way in which it will be held unlike the iPhone, which is normally held in portrait view (AKA Vertical). So you have to leave the choice to the user to eventually lock the orientation
The HIG do not actually state this as a requirement, but as a recommendation but there are many app that was rejected by this issue.
By the way if you want to this for a limit number of view controller you should implement:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if(interfaceOrientation == UIInterfaceOrientationPortrait){
return YES;
}
}
I'm trying to convert an iPhone app to iPad. The tricky things is that the iPhone app has to be locked to portrait view and the iPad app has to be locked to landscape view. I'm kind-of a noob at interface builder so I'm a little lost.
Any help is greatly appreciated. Thanks!
You need to override shouldAutorotateToInterfaceOrientation. A good place to put this is in the app delegate.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad &&
UIInterfaceOrientationIsLandscape(interfaceOrientation))
{
return YES;
}
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone &&
UIInterfaceOrientationIsPortrait(interfaceOrientation))
{
return YES;
}
return NO;
}
I'm not sure, but this may also support the phone being upside-down, which is a HIG no no. You might want to use interfaceOrientation == UIInterfaceOrientationPortrait instead for the phone.
You should have two nibs and load them separately depending on which device your application determines it is running on: one for the iPad and one for the iPhone. You can then set the orientation easily. NB: The iPad app should support all orientations variants (ie. if you support portrait, support portrait upside-down) and will most likely get rejected by Apple unless you have a compelling reason as to why it shouldn't.
