Utility application template and autorotation; force flipside view to always display

[boliva]

Just what the post title says... I've created an application using the Utility template in order to handle two 'flippable' views. I'm not using Interface Builder at all but creating all of my interfaces by code.

I wish to handle device auto rotation but only for the main view, with the flipside view always displaying in portrait mode. If of any importance, my application has the status bar hidden and my flipside view is added through an UINavigationController (instead of using a UINavigationBar as supplied by the application template).

When implementing the shouldAutorotateToInterfaceOrientation method, it only works on the RootViewController. I tried not implementing it there, only on the main view controller but it doesn't work. So I implemented it on the RootViewController, and have conditioned its return value to the display of the flipside view. This way I can prevent the view to rotate itself when the flipside view is displayed.

This is half the solution to the problem, however. If I'm on the main view rotated to a landscape orientation and display the flipside view, it doesn't display properly. I've tried several methods to make it appear with a portrait orientation regardless of the physical orientation of the device with no luck. I've looked through several similar threads and haven't found an answer, so any help would be greatly appreciated.

Best regards,

I played around with the utility template and have the same problem. Why does shouldAutorotateToInterfaceOrientation work only on the root controller? I thought the idea was to wire it to any UIViewController by implementing this method.

I had trouble with this same thing and this is what I found:

[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait];

Try that out.

I have tried the last suggestion, but still didn't find pleasing results.

Has anyone had any luck with this?

I too would like the mainViewController to display ONLY a landscape orientation and the flipSideViewController to display ONLY a portrait orientation.

Is this possible? Thx in advance...

yup! sure is!! I was just playing around myself to make this work. this might not be the best way to do this but what I have done is set an enum value to indicate weather we are working in landscape or portrait and then implement the following:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
	// Return YES for supported orientations
	switch (m_LayoutSetting) {
		case LayoutSettingPortrait:
			return (interfaceOrientation == UIInterfaceOrientationPortrait);
			break;
		case LayoutSettingLandscape:
			return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
			break;
	}
}

All you have to do when switching views is set the enum for your view controller, and call the rotate function as mentioned above.

as well: (from http://www.dejoware.com/blogpages/blog.html)

"I’ve discovered that the setOrientation message for UIDevice is only needed to get the iPhone Simulator to start with the desired orientation. It can be left out if you are testing on a device and/or for your “final” build, if you want to avoid even this one warning."

hope this helps.
