Question

In general my app works only in portrait, but one screen should be only in landscape. So I need to rotate my view, hide status bar and add a tool bar. When the status bar is visible my view is rotating fine, but after I perform [[UIApplication sharedApplication] setStatusBarHidden:YES], I see no rotation.. Here is the code:

- (void) viewWillAppear:(BOOL)animated
{
    //[[UIApplication sharedApplication] setStatusBarHidden:YES];

    CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(90));
    landscapeTransform = CGAffineTransformTranslate (landscapeTransform, +80.0, +100.0);
    [self.view setTransform:landscapeTransform];

    self.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    self.view.autoresizesSubviews = YES;
    self.view.bounds  = CGRectMake(0.0, 0.0, 480.0, 320.0);

    UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 20, 480, 40)];
    [[UIToolbar appearance] setBackgroundImage:[UIImage imageNamed:@"BarBg"] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 20, 100, 30)];
    label.text = @"asdasd";
    [toolBar addSubview:label];

    [self.view addSubview:toolBar];

    self.gallery.backgroundColor = [UIColor redColor];
}

Answer 1

The code you posted is working for me: the view appears rotated and i’m able to rotate it later having a default

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

I’d also add the following line at your viewWillAppear implementation:

[super viewWillAppear:animated];
