Team,
I am working on a support project and I have basic knowledge on iPhone. When I change the Orientation in my device, none of the below methods gets invoked at the time of Orientation change.
- (BOOL)shouldAutorotate {
UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIInterfaceOrientationPortrait) {
// your code for portrait mode
}
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskPortrait;
//return here which orientation you are going to support
}
I am pushing the screen through presentViewController and above methods gets invoked before pushing the screen, but nothing after the screen is pushed and when I change the orientation.
Also, I tried creating a Category as explained below, but I am getting viewController not found error, not sure what I am missing here...
In IOS7.If you use a UINavigationController, the rotate processing way is different!
See UINavigationController, can see it is a subclass of UIViewController, then that is in him there are listed in the above the rotation of the processing method; So wo need to use UINavigationController also do rotate processing,
My way is to add a Category to UINavigationController, do so.
In the Category. M writes
-(BOOL)shouldAutorotate {
return [[self.viewControllers lastObject] shouldAutorotate];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
any help is greatly appreciated!
For me the other two functions are also working but you can try to use the delegates below
From Apple Docs:
Sent to the view controller just before the user interface begins rotating.
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
duration:(NSTimeInterval)duration
Sent to the view controller after the user interface rotates:
-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
