UIWebView doesn't call didFailLoadWithError

Hello everybody.
I have a tabBarController project and i put an UIWebView on the first controller.
It's all working except the didFailLoadWithError.

Here it is the code

myappFirstViewController.h

Code:

#import <UIKit/UIKit.h>

@interface myappFirstViewController : UIViewController <UIWebViewDelegate> 

@property (weak, nonatomic) IBOutlet UIWebView *MY_uiwebview;

@end

myappFirstViewController.m

Code:

#import "myappFirstViewController.h"

@interface myappFirstViewController ()
@end

@implementation myappFirstViewController

@synthesize MY_uiwebview;


-(void)MY_uiwebview:(UIWebView *)MY_uiwebview didFailLoadWithError:(NSError *)error {

    NSLog(@"ERROR UIWEBVIEW");

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Connection error" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];

    [alert show];

}


- (void)viewDidLoad

{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload

{
    [self setMY_uiwebview:nil];
    [super viewDidUnload];
    // Release any retained subviews of the main view.

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{
   return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}



- (IBAction)Play {......etc..... }
@end

i cannot understand why (for example in AereoMode) it does not enter in

Code:

 -(void)MY_uiwebview:(UIWebView *)MY_uiwebview didFailLoadWithError:(NSError *)error

Thank you to everybody


p.s I have the same problem with iAd and

Code:

-(void)bannerViewDidLoadAd:(ADBannerView *)banner {

and also

Code:

-(void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error 

p.s. I am using xCode 4.3

 

here in the .h file

Code:

@interface myappFirstViewController : UIViewController <UIWebViewDelegate>

 

oh my god! I forgot the delegates!
now it's working!

thank you! and sorry for the oversight



p.s. yeah you guessed it, i'm learning ...
