UIInterfaceOrientation remains in portrait

Question

I've got a header/brand image which changes between iPad and iPhone, but will not change the picture when changing from portrait to landscape, which is really important that it does.

I have this HeaderView Class, which is called by tableViewControllers like this:

self.tableView.tableHeaderView = [[HeaderView alloc] initWithText:@""];

which holds a UIImageView:

@interface HeaderView : UIImageView{

}
- (id)initWithText:(NSString*)text;
- (void)setText:(NSString*)text;


@end

For the M file, we find where I'm not getting the result I want:

#import "HeaderView.h"

#define IDIOM    UI_USER_INTERFACE_IDIOM()
#define IPAD     UIUserInterfaceIdiomPad
@interface HeaderView()
{
    UILabel*label;
}
@end

@implementation HeaderView 

- (id)initWithText:(NSString*)text
{
    UIImage* img = [UIImage imageNamed:@"WashU.png"];
    UIImage* iPhonePortrait = [UIImage imageNamed:@"WashU2.png"];
    UIImage* image = [[UIImage alloc] init];


    UIInterfaceOrientation interfaceOrientation = [UIApplication     sharedApplication].statusBarOrientation;

        //different header image for different devices...
    if(IDIOM==IPAD){
        image = img;
    }
    else{
        if(UIInterfaceOrientationIsPortrait(interfaceOrientation)){
        image = iPhonePortrait;
        }
        else if(UIInterfaceOrientationIsLandscape(interfaceOrientation))
        {
            iPhonePortrait = nil;
            image = img;
        } 
    }    
    [headerImageView setImage:image];
    if (self = [super initWithImage:image]){

    }

    return self;
}

I also have added these methods:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation         {
    return YES;
}

-(BOOL)shouldAutorotate {
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}

I'm sure its a classic sort of question, but I'm reasonably stumped. Also, if I remove

[headerImageView setImage:image];

, and

[self addSubview:headerImageView];

, the image still shows up, which means that

if (self = [super initWithImage:image])

is doing all the display work.

If the 'img' and the 'iPhonePortrait' are identical besides a 90 degree rotation, then the rotation might be occurring but you can't tell. That is, you install the 'iPhonePortrait' but the UI rotates it 90 back to 'img' - end result is that it appears nothing happened... Possible solution thus is: don't change 'image' (just like you did for iPad), let the UI do the rotation. — GoZoner, Mar 01 '13 at 17:25

didRotateFromInterfaceOrientation is sent to your view controller after rotation, you can implement that to change your image.

-(void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
      ...change your image here
}

You are not actually assigning the image to the imageView. Add:

headerImageView.image = image;

somewhere after 'image' has been set (based on iPad vs iPhone and Portrait vs Landscape).

Thank you for your consideration, though this may have solved part of the problem, we're not cooking with gas yet. – Morkrom Mar 02 '13 at 23:14
You are adding the image to both the headerView and 'self' (with initWithImage). I really should only be in one. Also, how do you know that the headerView is actually viewable - you haven't set coordinates, etc. If your coordinates are messed up, then when rotating some stuff might drop off outside of the view. – GoZoner Mar 03 '13 at 01:29
You are correct... the subview has nothing to do with displaying the image but this: does... if (self = [super initWithImage:image]) { } – Morkrom Mar 04 '13 at 14:51

As your code, you do not need allocate (UIImage*)image property, because you will assign (UIImage*)img or (UIImage*)iPhonePortrait. And should assign image to headerImageView.image.

[headerImageView setImage:image];
