I developed an iOS app on Xcode 6.3 with iOS 8.3 .
Now I update Xcode to 7.1 with iOS 9.1 .
My app work perfectly on iPad with iOS 9.1
and all the views work perfectly in iPhone with iOS 9.1 expect one view .
With iphone 4s , 5 the problem is (lldb) with EXC_BAD_ACCESS(Code = 2 ,)
With iphone 5s , 6 , 6 plus , 6s , 6s plus no error message but the simulators hung all the time with max cpu and ram usage.
note : the implementation of view that causes the problem the same with iPad but in iPad work perfectly .
Please what the true analysis for the problem ?
