ios - マップ上のカスタム ImageView が iphone の MapView と一緒に回転しない

Question

こんにちは私は地図アプリケーションに取り組んでいます。mapview と imageview を回転させています。annotationView のサブビューです。Mapview の回転は完璧ですが、ImageView は Mapview に従って回転しておらず、常に北方向を指しています。

imageview を回転させるために以下のコードを使用しています:

-(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation

{

static NSString *identifier = @"annView";

MKPinAnnotationView *annView = (MKPinAnnotationView *) [self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];

annView=nil;
[annView setSelected:YES animated:NO];
if (annView == nil) 
{
    annView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
}

MyAnnotation *myAnnotation=(MyAnnotation *)annotation;
NSString *details;
if ([myAnnotation isKindOfClass:[MKUserLocation class]])
{
    //return nil;
}
else
{
    details=[myAnnotation annType];

}
NSLog(@"Details is  %@",details);
annView.canShowCallout = YES;

if([details isEqualToString:@"Current"])
{
    [[annView subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];
    annView.animatesDrop=NO;
    annView.canShowCallout=YES;//pin3.png// Parking_Psymbol//dus2
    annView.image=[UIImage imageNamed:@""];
    UIImage * locaterImage;
    locaterImage = [UIImage imageNamed:@"Locatermap.png"];

    locaterImageView = [[UIImageView alloc] initWithImage:locaterImage];
    locaterImageView.frame = CGRectMake(-28, -4, 70, 70);

    //--------For animating imageview ---------------------

    // Setup the animation
    [UIView beginAnimations: @"anim" context: nil];
    [UIView setAnimationDuration:2.0];
    [UIView setAnimationCurve:2.0];
    //[UIView setAnimationRepeatCount:10];
    [UIView setAnimationBeginsFromCurrentState:YES];
           [UIView setAnimationDelegate:self];
    [UIView commitAnimations];
    //--------For animating imageview ---------------------
    [annView addSubview:locaterImageView];
}

MapView を回転させる場合:

-(void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading

{

// Convert Degree to Radian and move the needle
float oldRad =  -manager.heading.trueHeading * M_PI / 180.0f;
float newRad =  -newHeading.trueHeading * M_PI / 180.0f;

CABasicAnimation *theAnimation;
theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.rotation"];
theAnimation.fromValue = [NSNumber numberWithFloat:oldRad];
theAnimation.toValue=[NSNumber numberWithFloat:newRad];
theAnimation.duration = 0.5f;
[mapView.layer addAnimation:theAnimation forKey:@"transform.rotation"];
self.mapView.transform = CGAffineTransformMakeRotation(newRad);
}

私はグーグルで検索しましたが、必要な答えが見つかりません。これを解決するためのアイデアを教えてください。

前もって感謝します。
