I am having a rather strange issue in iOS 7.
I have a view controller with a toolbar that has several UI bar buttons on the right. If I initially open the app in portrait mode, all the buttons respond to their click events. However, when I rotate the device and switch to landscape, some of the buttons stop responding to clicks. On the other hand, if I were to open up the app in landscape mode, buttons work, and when I switch back to portrait, buttons still work.
Is this a known issue? I'll be checking out the forums as well for any similar posts.
