Question

This should be an easy question – but I’m having a hard time figuring it out. I’m trying to create a property on an object so that during prepareForSegue I can tell the object what it’s delegate is. I know I could do this with protocols but I figured for this case a direct approach would be simplest. Unfortunately, the following code results in a compiler error:

#import <UIKit/UIKit.h>
#import "PlanningViewController.h"

@interface DepartmentViewController : UITableViewController

@property (nonatomic, weak) PlanningViewController *planningDelegate;

@end

When I type the property declaration, Xcode recognizes PlanningViewController and even displays the text for me to just tab through. The compiler, though, complains with:

Unknown type name 'PlanningViewController': did you mean 'UISplitViewController'?

What am I doing wrong?

PlanningViewController.h looks like this:

#import <UIKit/UIKit.h>
#import "DepartmentViewController.h"

@interface PlanningViewController : UITableViewController


// Table cell connections
- (IBAction)addItemPressed:(id)sender;


@end

Answer 1

Remove this line from your PlanningViewController.h header file:

#import "DepartmentViewController.h"

You have something of a loop in your header files.

Better still, make DepartmentViewController.h look like this (there is no need to include PlanningViewController.h in your header file):

#import <UIKit/UIKit.h>

@class PlanningViewController;

@interface DepartmentViewController : UITableViewController

@property (nonatomic, weak) PlanningViewController *planningDelegate;

@end
