iOS7: MKAnnotation centerOffset?

Question

So the centerOffset property of MKAnnotation does not seem to work on iOS7 for working with custom annotation images... Below are images taken in iOS6 (working) and in iOS7 (not working).

Do you guys know what's causing this issue? Is there any fix for this?

It's not that the centerOffset value is incorrent in iOS7, it's that the offset does not change whatever it receives as a value.

EDIT: Sample code:

- (void)viewDidLoad
{
    [super viewDidLoad];
    MapAnnotation *ann = [[MapAnnotation alloc] initWithName:@"Some annotation" latitude:46.910068 longitude:17.881984 tag:1 type:MAP_ANNOTATION_TYPE_REQUEST];
    self.mapView.delegate = self;
    [self.mapView addAnnotation:ann];

    MKCircle *circle = [MKCircle circleWithCenterCoordinate:CLLocationCoordinate2DMake(46.910068, 17.881984) radius:10];
    [self.mapView addOverlay:circle];

}

- (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id<MKOverlay>)overlay {

    if ([overlay isKindOfClass:[MKCircle class]]) {

        MKCircleView *cv = [[MKCircleView alloc] initWithCircle:overlay];
        cv.fillColor = [UIColor colorWithRed:247/255.f green:85/255.f blue:86/255.f alpha:0.2];
        cv.lineWidth = 1;
        cv.strokeColor = [UIColor colorWithRed:247/255.f green:85/255.f blue:86/255.f alpha:1.0];
        return cv;
    }

    return nil;
}

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
    //User location
    if ([annotation isKindOfClass:[MKUserLocation class]])
        return nil;

    //Annotations
    MKPinAnnotationView *pinAnnotation = nil;
    if(annotation != self.mapView.userLocation)
    {
        // Dequeue the pin
        static NSString *defaultPinID = @"myPin";
        pinAnnotation = (MKPinAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
        if ( pinAnnotation == nil )
            pinAnnotation = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID];

        pinAnnotation.image = [UIImage imageNamed:@"subscription-map-icon"];
        pinAnnotation.centerOffset = CGPointMake(0, -20);
    }

    return pinAnnotation;
}

MapAnnotation is a simple annotation class that has a few irrelevant properties.

EDIT:

As @Anna Karenina made me realize, I was using MKPinAnnotationView instead of MKAnnotationView. Apparently MKPinAnnotation has a baked in centerOffset, that is the reason behind the strange behaviour.

THE ORIGINAL ANSWER:

For anyone having the same issue, this seems to be a bug in iOS7.

Workaround:

Subclass MKAnnotationView and overwrite the setter method for the centerOffset property.

Nothing new in the .h header file, and this is how the .m implementation file should look like:

#import "MyAnnotationView.h"

@implementation MyAnnotationView
@synthesize centerOffset = _centerOffset;

-(id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
    }
    return self;
}

- (void)setCenterOffset:(CGPoint)centerOffset {
    _centerOffset = centerOffset;
}

@end

Don't miss the @synthesize part on the top!
