restricting autorotation on certain views - ios

Question

my app contains two table view controllers. in the first one i want the view to be able to be rotated left and right (in addition to the portrait mode), however in the second table view controller ( which i navigate to after tapping a cell from the first table) i want it to only be viewed in portrait mode. i tried this code but it didn't work, it keeps on rotating.
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL) shouldAutorotate {
return NO;
}
note: i did actually enabled the left/right/portrait orientation from the Summary tab of the project target. any fix?

Answer 1

Create a category for UINavigationController which include the following methods:
(Works both for iOS 6 and iOS 5)
- (BOOL)shouldAutorotate
{
return self.topViewController.shouldAutorotate;
}
- (NSUInteger)supportedInterfaceOrientations
{
return self.topViewController.supportedInterfaceOrientations;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return [self.topViewController shouldAutorotateToInterfaceOrientation:toInterfaceOrientation];
}
Then implement these methods in your controllers
First:
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
if (RUNNING_IPAD) {
return UIInterfaceOrientationMaskAll;
}
else {
return UIInterfaceOrientationMaskAllButUpsideDown;
};
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
if (RUNNING_IPAD) {
return YES;
}
else {
return toInterfaceOrientation != UIInterfaceOrientationMaskPortraitUpsideDown;
}
}
And Second:
- (BOOL)shouldAutorotate {
return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return NO;
}
The rotation settings of the project should look like:

Answer 2

Actually i found a solution for my problem:
-(BOOL)shouldAutorotate{
return YES;
}
-(NSInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
this will restrict a view to portrait even if you toggled the left/right orientations in the Summary tab of the project's Traget.
