Answer 1

1.for swift and ios9(the above answer will be like) --

    UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UIImagePickerController.self]).setBackButtonBackgroundImage(UIImage(named: "blank-button"), forState: UIControlState.Normal, barMetrics: UIBarMetrics.Default)

2.if you want to modify backIndicatorImage of UINavigationBar

UINavigationBar.appearanceWhenContainedInInstancesOfClasses([UIImagePickerController.self]).backIndicatorImage = UIImage(named: "backButton")//or nil

3.if you want to modify backIndicatorTransitionMaskImage

UINavigationBar.appearanceWhenContainedInInstancesOfClasses([UIImagePickerController.self]).backIndicatorTransitionMaskImage =UIImage(named: "backButton")// nil

Answer 2

Try using this:

    [[UINavigationBar appearanceWhenContainedIn:[YourClassThatsNotAUIImagePicker class], nil] setBackButtonBackgroundImage:someOtherImage forBarMetrics:UIBarMetricsDefault];

That should limit your appearance setting to only the classes you list and therefore leave the UIImagePickerController alone.

Answer 3

 [[UIBarButtonItem appearanceWhenContainedIn:[UIImagePickerController class], nil] setBackButtonBackgroundImage:[UIImage imageNamed:@"blank-button"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

this is the correct way
