iOS7 iPad Landscape only app, using UIImagePickerController

I believe this is a common issue and many answers don't work anymore, many just partial, if you are under iOS7 and your iPad app is Landscape only, but you want to use the UIImagePickerController with source UIImagePickerControllerSourceTypePhotoLibrary or UIImagePickerControllerSourceTypeCamera.

How to set it right, so it's working 100%? And you don't get mixed orientations and avoid the error "Supported orientations has no common orientation with the application, and shouldAutorotate returns YES".

If your iPad app is landscape only in all conditions, just do these 3 steps :

1) In your app delegate

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return UIInterfaceOrientationMaskAll;
}

2) Create a category header

#import "UIViewController+OrientationFix.h"

@implementation UIViewController (OrientationFix)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}

- (BOOL)shouldAutorotate {
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

@end

3) Create a category implementation

#import "UIImagePickerController+OrientationFix.h"

@implementation UIImagePickerController (OrientationFix)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}

- (BOOL)shouldAutorotate {
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscape;
}

@end

Note: You don't need to import these categories anywhere, just enough they are compiled with the project

Note: no need to implement these methods in any VC

Note: no need to change your plist supported orientations

This is tested and working under any conditions

I have seen this code from Apple's Sample Code.

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;

Due to this UIModalPresentationCurrentContext UIImagePickerController will be opened as per device's current orientation.

Apple's documentation says:

"Important: The UIImagePickerController class supports portrait mode only."

Although, it works fine in landscape for full screen and on iOS 6.
