UIWebView doesn't call didFailLoadWithError

hello everybody.
have tabbarcontroller project , put uiwebview on first controller.
it's working except didfailloadwitherror.

here 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]; // additional setup after loading view, typically nib. }  - (void)viewdidunload  {     [self setmy_uiwebview:nil];     [super viewdidunload];     // release retained subviews of main view.  }  - (bool)shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation  {    return (interfaceorientation != uiinterfaceorientationportraitupsidedown); }    - (ibaction)play {......etc..... } @end

cannot understand why (for example in aereomode) not enter in

 -(void)my_uiwebview:(uiwebview *)my_uiwebview didfailloadwitherror:(nserror *)error
