Question

I am currently working on a project and I need to support both portrait and landscape orientation. I have read several books, and all of them tell me to do different things. The view I want to support landscape orientation is simple. It is a UINavigationBar and a UIWebview which is attached to the viewcontrollers view. I have made the view programatically.

Is it correct that I use this method:
– (void)willAnimateRotationToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration;

I have seen that prior to iOS 3 there was two other methods that were invoked. However I do not target my app below iOS 3.

This code is working but my question is if it is the correct way of doing it programmatically because I don’t want to use the InterfaceBuilder on this view.

Codesnippet (working)

- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)x duration:(NSTimeInterval)duration {
   if (UIInterfaceOrientationIsLandscape(x)) {
      topbar.frame = CGRectMake(0.0f, 0.0f, 480.0f, 44.0f);
   }
}

And is it correct that I don’t need to apply any animation, iOS will handle this right?

Answer 1

You can use the below two methods to support interface orientations

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{

 //Set the boolean variable for interface orientation condition. 

}


- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation duration:(NSTimeInterval)duration {
//Set the coordinates of the Views you are using.

}

Yes you do not have to worry about the animation part,the OS will take care of it.
