My app can autorotate but I need one of the views to only show in portrait mode and don't know how to achieve this.
I tried this (among other things) but the view in question still rotates:
// ViewController.m
-(BOOL)shouldAutorotate
{
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
Can someone kindly point out what I'm doing wrong? Thanks.
-edit-
It's for iOS 6.1
When a UINavigationController
is involved, create a category on the UINavigationController
and override supportedInterfaceOrientations
.
#import "UINavigationController+Orientation.h"
@implementation UINavigationController (Orientation)
- (NSUInteger)supportedInterfaceOrientations {
return [self.topViewController supportedInterfaceOrientations];
}
- (BOOL)shouldAutorotate {
return YES;
}
@end
Now, iOS containers (such as UINavigationController) do not consult their children to determine whether they should autorotate.
How to create a category
1. Add a new file (Objective c- category under cocoa touch)
2. Category
: Orientation on UINavigationController
3. Add the above code to UINavigationController+Orientation.m
