I have an application and designed for only for portrait orientation. However I dont know how to restrict to use only portrait mode, once user upside down or landspace mode, I dont want my screen orinetation changes accordingly.
Any ideas how to do it?
That can be specified in the App Summary (and also in the rootviewcontroller (whether that be a Nav Controller, TabBar Controller, etc) by overriding this method:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
Here's an updated view of the place where you can make the change in XCode 8.1
Notice that you choose that item (App Summary) on the far left at the top of the project navigator.
Then, on the right side you need to make sure that General is chosen at the top, then scroll down if needed and you'll see the Device Orientation settings.
