    <p>I had the pin drag working but was trying to figure out why the pin annimations that occur when you don't override setDragState - no longer work in my implementation. Your question contained my answer .. Thanks!</p> <p>Part of the problem with your code is that once you override the setDragState function, per the xcode documentation, you are responsible for updating the dragState variable based on the new state coming in. I would also be a little concerned about your code calling itself (setDragState calling [self setDragState]).</p> <p>Here is the code I ended up (with your help) that does all of the lifts, drags and drops as I expect them to occur. Hope this helps you too!</p> <pre><code>- (void)setDragState:(MKAnnotationViewDragState)newDragState animated:(BOOL)animated { if (newDragState == MKAnnotationViewDragStateStarting) { // lift the pin and set the state to dragging CGPoint endPoint = CGPointMake(self.center.x,self.center.y-20); [UIView animateWithDuration:0.2 animations:^{ self.center = endPoint; } completion:^(BOOL finished) { self.dragState = MKAnnotationViewDragStateDragging; }]; } else if (newDragState == MKAnnotationViewDragStateEnding) { // save the new location, drop the pin, and set state to none /* my app specific code to save the new position objectObservations[ACTIVE].latitude = pinAnnotation.coordinate.latitude; objectObservations[ACTIVE].longitude = pinAnnotation.coordinate.longitude; posChanged = TRUE; */ CGPoint endPoint = CGPointMake(self.center.x,self.center.y+20); [UIView animateWithDuration:0.2 animations:^{ self.center = endPoint; } completion:^(BOOL finished) { self.dragState = MKAnnotationViewDragStateNone; }]; } else if (newDragState == MKAnnotationViewDragStateCanceling) { // drop the pin and set the state to none CGPoint endPoint = CGPointMake(self.center.x,self.center.y+20); [UIView animateWithDuration:0.2 animations:^{ self.center = endPoint; } completion:^(BOOL finished) { self.dragState = MKAnnotationViewDragStateNone; }]; } } </code></pre>

    1. COHow did it work perfectly? When you drag the pin outside your screen, it results in a crash.

    2. COThis works, but one thing baffles me: In my MKMapViewDelegate, I override mapView:annotationView:didChangeDragState. MKAnnotationView base class produces two transitions: From 0->1 when the drag starts, and 1->4 when it's ending. This solution above seems to follow Apple's guidelines to the T, but it produces a 0->2 and a 2->0 transition. I can live with it but it's weird - I think Apple's documentation is off, to be honest.

    3. COI think you need to call `self.dragState = ...`, not `dragState =`. Otherwise, the KVO notifications won't get sent, and the map view won't see the dragging state change.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
