Answer 1

- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}

This should work. If your app only allows portrait. You have to do some extra work in the app delegate. You need to set a boolean property, call it restrictRotation. Then include AppDelegate.h in your class and set restrictRotation to true when you need to rotate it

-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if(self.restrictRotation)
    return UIInterfaceOrientationMaskPortrait;
else
    return UIInterfaceOrientationMaskAll;
}

Then in your class

- (void) orientationChanged:(NSNotification *)note
{
UIDevice * device = note.object;
switch(device.orientation)
{
    case UIDeviceOrientationPortrait:
        //do stuff
        break;
    case UIDeviceOrientationLandscapeLeft:
         //do stuff
        break;
    case UIDeviceOrientationLandscapeRight:
       //do stuff
        break;
    default:
        break;
   };
}
-(void) restrictRotation:(BOOL) restriction
{
     AppDelegate* appDelegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
appDelegate.restrictRotation = restriction;
}

That should help

Answer 2

In your ViewController.m:

Make the SubClass(ViewController) of Image Picker Controller

@interface ViewController : UIImagePickerController

@end

@implementation ViewController

// Disable Landscape mode.

    - (NSUInteger)supportedInterfaceOrientations{

        return UIInterfaceOrientationMaskLandscape;
    }
@end

Use the following code:

UIImagePickerController* picker = [[ViewController alloc] init];
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        picker.delegate = self; 
 // etc.... do like Just as Default ImagePicker Controller

But make sure you check Portrait in deployment info,

because UIImagePickerController only supports Portrait mode. If you don't support portrait "globally" the image picker will crash as it has no usable orientations.
