Why am I getting an error?

Why am I getting these errors? alt text http://img39.imageshack.us/img39/2203/help.tif

It says:

Error: Request for member "jokeTableView" for something that is not a construct or union

What does it mean? And why does it break. I tried reading initWithStyle but I just could catch up with it

Here is my .h file:

#import <UIKit/UIKit.h>


 @interface TableViewController : UITableViewController {

NSMutableArray *jokes;
IBOutlet UITableView *jokeTableView; 


 } 

 @property (nonatomic, retain) NSMutableArray *jokes;

 @end

Thanks!

Your object (TableViewController) doesn't have a property named jokeTableView.

To access the jokeTableView with the dot special operator, it must be a property. Otherwise, you need to access it using key-encoding compatible methods, or directly using the -> operator (or just use it like an ivar and no reference to self):

jokeTableView.delegate = self;

or

self->jokeTableView.delegate = self;


or

[self jokeTableView].delegate = self;

or

@property (retain) UITableView *jokeTableView;
// later...
self.jokeTableView.delegate = self;

Also note that you are setting the socket in the initializer and this will not work. You must set this in the method - [TableViewController awakeFromNib], as self-> jokeTableView will be zero when the initializer is actually called (which happens in IB before serializing the object to the nib file).

Since you do this at init time, the exit points must be NULL, so this initialization shouldn't do anything. This should be done at awakeFromNib as early as possible.
