ipad app not works for landscape mode

Question

iPad runs fine for portrait, but not working for Landscape,

I use this code

- (BOOL) isPad{ 
#ifdef UI_USER_INTERFACE_IDIOM
    return (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
#else
    return NO;
#endif
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    if ([self isPad]) {

        return YES;
    }
    else 
    {
        return UIInterfaceOrientationIsPortrait(interfaceOrientation);
    }

}


- (BOOL)isPadLandscape
{

    return (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad
            && (self.interfaceOrientation == UIInterfaceOrientationLandscapeRight
                || self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft));

}

- (BOOL)isPadPortrait
{

    return (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad
            && (self.interfaceOrientation == UIInterfaceOrientationPortrait
                || self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown));
}




- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    if ([self isPadPortrait])
    {
        [imageView setFrame:CGRectMake(0, -50, 768, 1024)];        
    }
    else if ([self isPadLandscape])
    {
        [imageView setFrame:CGRectMake(0, 0, 1024, 768)];
    }
}

i try to call -(BOOL)isPadLandscape method during debug,but that method not call,

What could be wrong?

Don't forget to set property Supported interface orientations (iPad) in your Info.plist file for appropriate supported positions.

Or try this:

- (BOOL) isPad{ 
    return [[UIDevice currentDevice].model hasPrefix:@"iPad"];
}
