当我们点击我的定制注解别针时，定制的calloutview不会显示在视图的中心(Iphone)

当我们点击自定义注解别针时，calloutview不会显示在视图的中心，而是显示在视图中的一半，而保留在视图之外。请任何人帮助我。提前感谢

    CGSize const kMultiRowCalloutCellSize = {300,140};

    - (id)initWithAnnotation:(id<MultiRowAnnotationProtocol>)annotation reuseIdentifier:(NSString *)reuseIdentifier onCalloutAccessoryTapped:(MultiRowAccessoryTappedBlock)block {
    self = [super initWithAnnotation:(id<MKAnnotation>)annotation reuseIdentifier:reuseIdentifier];
    if (self) {
        self.contentHeight = 80.0;
        _yShadowOffset = 6;
        self.offsetFromParent = CGPointMake(78, -14); //this works for MKPinAnnotationView
        self.enabled = NO;
        self.backgroundColor = [UIColor clearColor];
        self.cellInsetX = 15;
        self.cellOffsetY = 10;
        self.onCalloutAccessoryTapped = block;
        [self setTitleWithAnnotation:annotation];
        [self setCalloutCellsWithAnnotation:annotation];
    }
    return self;
}

annotationView.centerOffset = CGPointMake( annotationView.centerOffset.x + annotationView.image.size.width/2, annotationView.centerOffset.y - annotationView.image.size.height/2 );

在下面提到的委托方法中添加这些行。

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