How to check the orientation of device at any point off time programmatically in iPhone ?
Thank You.

Answer 1

Here are macros UIDeviceOrientationIsLandscape and UIDeviceOrientationIsPortrait
so rather checking separately you can do it like this ...
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
{
// code for landscape orientation
}
OR
if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation))
{
// code for Portrait orientation
}

Answer 2

Try it.
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
if ( ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait) )
{
// do something for Portrait mode
}
else if(([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight) || ([[UIDevice currentDevice] orientation] == UIInterfaceOrientationLandscapeLeft))
{
// do something for Landscape mode
}

Answer 3

Try also:
UIInterfaceOrientationIsPortrait(orientation)
and
UIInterfaceOrientationIsLandscape(orientation)

Answer 4

-[UIViewController interfaceOrientation]
However it is possible to retrieve the deviceOrientation, independent from the current interface orientation:
[[UIDevice currentDevice] orientation]
Read the documentation for more information though, you need to do some more things to make that work.

Answer 5

You can also check within the function
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
if(interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
//do for portrait
}
else
{
//do for Landscape
}
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight ||
interfaceOrientation == UIInterfaceOrientationPortrait ||
interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}

Answer 6

You should place [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; in your AppDelegate didFinishLaunchingWithOptions
Then, anywhere in your application you can get the current orientation with:
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
And test orientation with:
UIInterfaceOrientationIsPortrait(orientation)
UIInterfaceOrientationIsLandscape(orientation)
