Thank you very much.
-(NSUInteger) supportedInterfaceOrientations

Answer 1

If you are using navigationController,
Create a category like this,
#interface UINavigationController (Rotation_IOS6)
#end
#implementation UINavigationController (Rotation_IOS6)
-(BOOL)shouldAutorotate
{
if([self.visibleViewController isMemberOfClass:NSClassFromString(#"SecondViewController")])
{
return UIInterfaceOrientationMaskLandscapeLeft
}
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return [[self topViewController] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
if([self.visibleViewController isMemberOfClass:NSClassFromString(#"SecondViewController")])
{
return UIInterfaceOrientationMaskLandscapeLeft
}
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
#end

Answer 2

- (BOOL)shouldRotateToOrientation:(UIDeviceOrientation)orientation {
if (orientation == UIDeviceOrientationLandscapeLeft) {
return NO;
}
else if (orientation == UIDeviceOrientationLandscapeRight) {
return NO;
}
else if (orientation == UIDeviceOrientationPortrait) {
return NO;
}
else if (orientation == UIDeviceOrientationPortraitUpsideDown) {
return YES;
}
}
//Use this method to check which orientation going to execute and you can return no if you
//want to stop orientation and if you return yes then orientation execute

First you need to add the category of NavigationController
Declare that bool in AppDelegate to used in all over projcet.
Declare property AppDelegate.h
#property BOOL * islandscape;
AppDelegate.m file
#synthesize islandscape;
.h file
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
#interface UINavigationController (orientation1)
#end
.M File
#import "UINavigationController+orientation1.h"
#implementation UINavigationController (orientation1)
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
AppDelegate * delegate=(AppDelegate *)[[UIApplication sharedApplication]delegate];
if (delegate.islandscape)
{
// for iPhone, you could also return UIInterfaceOrientationMaskAllButUpsideDown
return UIInterfaceOrientationMaskLandscape;
}
return UIInterfaceOrientationMaskPortrait;
}
#end
and then used that bool varible in SeconViewController.
delegate.islandscape=Yes;
