IBOutlet UITextField and UILabel not showing up in the Interface Builder

Question

This is weird -- I have defined the fields for UITextField and UILabel's... but they are not showing up for me to connect the objects to the View. Any ideas?
DistanceViewController.h
@interface DistanceViewController : UIViewController {
IBOutlet UITextField *txtMeters;
IBOutlet UITextField *txtYards;
IBOutlet UITextField *txtStatuteMiles;
IBOutlet UITextField *txtNauticalMiles;
IBOutlet UILabel *lblStatus;
@property (nonatomic,retain) IBOutlet UITextField *txtMeters;
@property (nonatomic,retain) IBOutlet UITextField *txtYards;
@property (nonatomic,retain) IBOutlet UITextField *txtStatuteMiles;
@property (nonatomic,retain) IBOutlet UITextField *txtNauticalMiles;
@property (nonatomic,retain) IBOutlet UILabel *lblStatus;
- (IBAction) updateText: (id) sender;
@end
DistanceViewController.m
@synthesize txtMeters, txtYards, txtStatuteMiles, txtNauticalMiles, lblStatus;
- (IBAction) updateText: (id) sender {
The DistanceViewController.xib does not allow me to attach any of the fields to their respective variables. It does allow me to connect the method updateText though.... it compiles and the test run shows the fields, but the method never triggers (of course...)

Answer 1

Have you tried Build->Clean All Targets? That's my best guess, but if it doesn't help here are a few sanity checks that might point somewhere:
Ctrl-click on the view controller object (normally the File's Owner proxy) to bring up its connections panel. Do you see updateText under received actions, but none of the declared IBOutlets under Outlets? Do you see the view outlet, and is it connected to the view? I assume the controller object is set to the DistanceViewController class (else how does it know about updateText?), but it wouldn't hurt to check. I would even go to the Identity Inspector, set the object's class to UIViewController, look at the connections panel, then set it back to DistanceViewController. Select the controller object again, Ctrl-click to bring the connections panel back, then open the Connections Inspector. Does the panel match the inspector?
If none of the above give you a clue, I might go back to DistanceViewController.h, remove the action method, then go back to IB and see if the change is reflected in the connections panel or inspector.
I can't think of what else to try atm, but I'll post again if I have another idea.
