How can I display one UIView in landscape?

Question

I\'ve looked at every question so far and none seem to actually answer this question.

I created a UITabBarController and added several view controllers to it. Most

Answer 1

Override the Orientation method in your controller class and force it to Landscape like this :

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    // Overriden to allow any orientation.
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

Simple and efficient !

Answer 2

Here's what I'm doing to do this:

first, put this define at the top of your file, right under your #imports:

#define degreesToRadian(x) (M_PI * (x) / 180.0)

then, in the viewWillAppear: method

[[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO];     
if (self.interfaceOrientation == UIInterfaceOrientationPortrait) {  
    self.view.transform = CGAffineTransformIdentity;
    self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90));
    self.view.bounds = CGRectMake(0.0, 0.0, 480, 320);
}

if you want that to be animated, then you can wrap the whole thing in an animation block, like so:

[UIView beginAnimations:@"View Flip" context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

[[UIApplication sharedApplication] setStatusBarHidden:YES animated:NO];     
if (self.interfaceOrientation == UIInterfaceOrientationPortrait) {  
    self.view.transform = CGAffineTransformIdentity;
    self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90));
    self.view.bounds = CGRectMake(0.0, 0.0, 480, 320);
}
[UIView commitAnimations];

Answer 3

shouldAutorotateToInterfaceOrientation only work if all the view in the tabbarcontroller or all the view controllers in the navigationcontroller agree upon a rotation.

Answer 4

An post on a forum that might help. Short answer is you have to manually rotate your view or controller once the view has been drawn, in the viewWillAppear: method

CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(degreesToRadian(90));
landscapeTransform = CGAffineTransformTranslate (landscapeTransform, +80.0, +100.0);

[[appDelegate navController].view setTransform:landscapeTransform];
