This is about an iPhone App using MKMapKit:

I created a custom MKAnnotationView for a draggable Annotation. I want to create a custom animation. I set a custom pin image and the annotation is draggable (which both is not shown here, it happens in the mapview) with the following code:

```
- (void) movePinUpFinished {

     [super setDragState:MKAnnotationViewDragStateDragging];
     [self setDragState:MKAnnotationViewDragStateDragging];
}

- (void) setDragState:(MKAnnotationViewDragState) myState {
     if (myState == MKAnnotationViewDragStateStarting) {
          NSLog(@"starting");
          CGPoint endPoint = CGPointMake(self.center.x,self.center.y-20);
          self.center = endPoint;
          [self movePinUpFinished];
     }
     if (myState == MKAnnotationViewDragStateEnding) {
          NSLog(@"ending");
          [super setDragState:MKAnnotationViewDragStateEnding];
          [self setDragState:MKAnnotationViewDragStateNone];
          [super setDragState:MKAnnotationViewDragStateNone];
     }
     if (myState == MKAnnotationViewDragStateDragging) {
          NSLog(@"dragging");
     }
     if (myState == MKAnnotationViewDragStateCanceling) {
          NSLog(@"cancel");
     }
     if (myState == MKAnnotationViewDragStateNone) {
          NSLog(@"none");
     }
}

```

Everything works fine, the annotation is moved up a bit, is draggable and when i release the annotation, the mapview receives the "dragstateending".

But now I want the animation to run over a time period and change the dragStateStarting to the following:

```
if (myState == MKAnnotationViewDragStateStarting) {
          NSLog(@"starting");
          CGPoint endPoint = CGPointMake(self.center.x,self.center.y-20);
          [UIView animateWithDuration:1.0
           animations:^{ self.center = endPoint; }
           completion:^(BOOL finished){ [self movePinUpFinished]; }];
     }

```

The animations runs as wanted over the period of a second and the annotation is draggable. But when I release the annotation, the mapview is not receiving the ending through the delegat. What I also recognized was that when I am doing the animation with "UIView animateWithDuration..." is that immedently after beginning the dragging, as the animation starts, the ballon of the annotation opens. When i am setting the new center without the animation, the balloon keeps closed and is only opened after finishing the dragging by releasing the annotation.

What am I doing wrong? Is this the right way to override setDragState. Do I really have to call the super class? But without setting the dragstate in the superclass my mapview didnt realized the changes of the dragstate.

I wonder about the original implementation of MKPinAnnotationView, but because it is an internal Class I couldn't find a description of the setDragState method.

Thx for help. Cheers,
