I have been stuck on this problem for ages and I have browsed through the answers on stack overflow but they don't seem to be working. I tried by deleting all the original connections and then connecting them again with no luck. Everything compiles fine but I am getting this error:
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<UIApplication 0x6a067d0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key imageView.'

heres a picture of my xib, the File Owner custom class is set to ViewController like it should be.

Please I really need help on this, it has been happening for a couple of days. I remade the project from scratch and had no luck. I can put up my ViewController.h and ViewController.m code if it is needed. I have imageView declared as "@property (nonatomic, retain) IBOutlet UIImageView *imageView;"
Help would be greatly appreciated. I am still quite new to programming in objective C and Xcode.
here is the ViewController.h:
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>
{
BOOL newMedia;
}
@property (nonatomic, retain) IBOutlet UIImageView *imageView;
- (IBAction) useCamera;
- (IBAction) useCameraRoll;
@end
here is the ViewController.m:
#import "ViewController.h"
#import "MobileCoreServices/UTCoreTypes.h"
@implementation ViewController
@synthesize imageView;

[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.

}
