Question

UPDATE: All working now, forgot to link up the view in the .xib file.

I have imported my view controller’s implementation files like so;

#import "TopicsListParentViewController.h"

When I write:

TopicsListParentViewController *tlparentview;

There are no errors at first, but then when building the project, this error appears:

Unknown type name ‘TopicsListParentViewController’; did you mean ‘TopicsListViewController’?

Why is this and how can I fix it? Here’s a screenshot to help you imagine the scene more accurately:

EDIT: Here are the .h and .m for “TopicsListParentViewController”

.h Implementation File:

#import "SuperChatAppDelegate.h"
#import "TopicsListViewController.h"

@interface TopicsListParentViewController : UIViewController {

IBOutlet UIView *parentview;

IBOutlet TopicsListViewController *topicsListViewController;

}

@end

.m Implementation File:

//
//  TopicsListParentViewController.m
//

#import "TopicsListParentViewController.h"

@implementation TopicsListParentViewController 

-(void)viewDidLoad
{

[parentview addSubview:topicsListViewController.tableView];
NSLog(@"Added subview");

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations.
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation ==     UIInterfaceOrientationLandscapeRight);
}

- (void)dealloc {
[super dealloc];
}

@end

Double check to make sure your files properly have.

 @interface TopicsListParentViewController
  ...
 @end

and

 @implementation TopicsListParentViewController
  ...
 @end
