Add object to NSMutableArray from other class

Question

I have a view controller class called PresidentsViewController that sets up data in a UITableView. This data is in the form of NSMutableArray

Answer 1

My suspicion here would be that you have a property defined as @property (nonatomic,copy) NSMutableArray *list; Are you getting and exception trying to add the object into the array? If so, it's likely because the copy modifier is returning an immutable copy of the array. Try to create a method that takes the object and adds it to the list without using self.list ... just [list addObject] and if that works then this is your problem.
