I have a custom UITableViewController with many UITableViewCells inside, each of which has a checkbox. Within the custom UITableViewCell class there is a method which happens when the checkbox is checked. I also have an NSMutableArray as a property of the UITableViewController and I want to add an object to it everytime the checkbox is checked but I am having trouble accessing the other class. Some help please?

If you have custom cell class, create a cell's delegate.
@class MyCustomTableViewCell;
@protocol MyCustomCellDelegate <NSObject>
- (void)cell:(MyCustomTableViewCell *)cell checkboxValueDidChange:(BOOL)checked;
@end
@interface MyCustomTableViewCell : UITableViewCell
@property(nonatomic, weak) id <MyCustomCellDelegate> delegate;
@end
Then in tableView:cellForRowAtIndexPath: assign your controller as table view cell's delegate. Having this, you'll receive callback.
- (void)cell:(MyCustomTableViewCell *)cell checkboxValueDidChange:(BOOL)checked {
// get cell's index path if you need
if (checked) {
[self.myMutableArray insertObject:myObject atIndex:myIndex];
}
}
Hope it helps.
