Basically heres the situation: I have a menu controller using REFrostedViewController(can be found here: https://github.com/romaonthego/REFrostedViewController). The menu controller is working perfectly for everything but this, I tap on a cell in my menu, it dismisses the menu to goto the view it is on already and to call an action sheet, this is what happens.

Here is my code to call the action sheet: 

reportssheet = [[UIActionSheet alloc] initWithTitle:@"Choose Your Report" delegate:self cancelButtonTitle:@"Canel" destructiveButtonTitle:nil otherButtonTitles:@"Class List",@"Grade (Student)",@"Attendance Total (Student)",@"Assignment Grade (Class)",@"Assignment Grade (Student)", @"Assignments Given (Class)",@"Weighted
