I'm coding a new app and I'm experiencing a problem with making it work for the second generation 12.9 inch ipad. The uiview does not appear where it should in one of the view controllers and the segue to the next view controller causes the app to crash. However, these problems do not appear in any other ipad version nor for the iphone or ipod while simulating the app. There are some warning messages too about fixed width constraints, which I'm not sure how to address properly. Can anyone suggest the cause of these issues? thanks for your ideas.
