Starting iOS application in desired orientation

I have an storyboard based application, and I noticed that when I started the application on iPhone, it always started on landscape, then after the application started it would then autorotate to portrait if the cell phone was in portrait mode. When I ran the application on the iPad instead, it would always start on portrait. So I searched the web to find how to fix it, and by examining some posts about it and tinkering a little with Xcode, I found the following solution to the problem: Inside the application target, there's a -Info.plist file. This file contains some configuration properties of the application. Among those, there's a "Supported interface orientations" property for both iPhone and iPad. My configuration for the iphone was the following: 

Item 0	Landscape (left home button)
Item 1	Landscape (right home button)
Item 2	Portrait (button home button)

I found out that the order of these items matter. The application will always start on the first orientation in this list. I was then able to solve my problem by dragging the Portrait (button home button) to the top of the list so that it turned into Item 0. Then, after I started my application again, it started in Portrait by default. Just posting in the case that someone has the same problem.
