iOS SKMaps 未加载注释（Xcode 6，Objective C）

Question

I'm having problems with SKMaps for iOS. It seems that it is not loading the annotations. It should display an annotation somewhere around the lake

Also on the initialization, it doesn't go to the specified region.

InitMap Method

-(void) initMap {
    /*
     self.mapView = [[SKMapView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 
        CGRectGetWidth(self.view.frame), CGRectGetHeight(self.view.frame))];
    */
    self.mapView = [[SKMapView alloc] initWithFrame:
        CGRectMake(0.0f, 0.0f, 238.0f, 157.0f)];

    self.mapView.autoresizingMask 
        = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

    // set initial coordinates
    // la mesa dam
    //_loc2DLamesaDam = CLLocationCoordinate2DMake(14.7241845,121.085998);
    SKCoordinateRegion region;
    region.center = CLLocationCoordinate2DMake(14.7241845,121.085998);
    region.zoomLevel = 17;

    self.mapView.visibleRegion = region;

    //[self.view addSubview:mapView];
    //show the compass
    self.mapView.settings.showCompass = YES;
    //hide the map scale
    self.mapView.mapScaleView.hidden = YES;
    self.mapView.settings.rotationEnabled = NO;
    self.mapView.settings.followUserPosition = YES;
    SKMapZoomLimits zoomLimits;
    zoomLimits.mapZoomLimitMax = 17;
    zoomLimits.mapZoomLimitMin = 10;
    self.mapView.settings.zoomLimits = zoomLimits;

    self.mapView.settings.headingMode = SKHeadingModeRotatingMap;

    [self determineMapStyle];

    [self addAnotation:CLLocationCoordinate2DMake(14.7241845,121.085998) 
          annotationId:1
             imageName:nil
           imageHeight:0.0f
            imageWidth:0.0f
       skAnotationType:SKAnnotationTypePurple];
}

AddAnotation method

-(void)addAnotation:(CLLocationCoordinate2D) coordinate annotationId:(int) annotationId
        imageName:(NSString*)imageName imageHeight:(float) imageHeight imageWidth:(float) 
        imageWidth skAnotationType:(SKAnnotationType) skAnotationType {

[mapView removeAnnotationWithID:annotationId];

SKAnnotation *annotation = [SKAnnotation annotation];
annotation.identifier = annotationId;
annotation.location = coordinate; //CLLocationCoordinate2DMake(52.5237, 13.4137);
SKAnimationSettings *animationSettings = [SKAnimationSettings animationSettings];

if(imageName.length==0 || imageName == (id)[NSNull null])
{
    annotation.annotationType = skAnotationType;      
} else {
    //Annotation with view
    //create our view
    UIImageView *coloredView = [[UIImageView alloc] initWithFrame:
        CGRectMake(0.0, 0.0, 128.0, 128.0)];
    coloredView.image = [UIImage imageNamed:imageName];

    //create the SKAnnotationView
    SKAnnotationView *view = [[SKAnnotationView alloc] initWithView:coloredView 
        reuseIdentifier:@"viewID"];

    //set the custom view
    annotation.annotationView = view;

}
[self.mapView addAnnotation:annotation withAnimationSettings:animationSettings];
//[mapView addAnnotation:viewAnnotation withAnimationSettings:animationSettings];}

Setting the visible region works, as well as adding an annotation with a custom view. This is the code that works in our demo project:

UIImageView *customAnnotationView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 50, 50)]; 
    customAnnotationView.backgroundColor = [UIColor greenColor]; 
    customAnnotationView.image = [UIImage imageNamed:@"santa"]; //"santa.png" was added to resources 

    SKAnnotationView *annotationView = [[SKAnnotationView alloc] initWithView:customAnnotationView reuseIdentifier:@"reusableIdentifier"]; 

    SKAnnotation *annotation = [SKAnnotation annotation]; 
    annotation.identifier = 123456; 
    annotation.location = region.center; 
    annotation.annotationView = annotationView; 

    [self.mapView addAnnotation:annotation withAnimationSettings:[SKAnimationSettings animationSettings]];
