    <p>I have a UIView with some labels in it I built in my storyboard that I want to animate when a map annotation is clicked. I have everything working great except the animations are a bit off. The first time you click an annotation the frame position is not animated. But if I deselect and then reselect the annotation it animates fine from then on. I also animate the background color and that seems to be working fine on the first select so whatever it is is peculiar to the frame property, perhaps because it's no set up appropriately at load? Again I did all that in the storyboard so I don't know what I'm missing.</p> <p>Code for my Labels/View (all built in my storyboard and using reference outlets to the proper IBOutlets). file.h:</p> <pre><code>@property (weak, nonatomic) IBOutlet UIView *stationinfo; @property (weak, nonatomic) IBOutlet UILabel *stationname; @property (weak, nonatomic) IBOutlet UILabel *stationsong; @property (weak, nonatomic) IBOutlet UILabel *stationartist; </code></pre> <p>file.m:</p> <pre><code>@synthesize stationinfo; @synthesize stationname; @synthesize stationsong; @synthesize stationartist; </code></pre> <p>Please find code for callbacks below:</p> <pre><code>- (void) mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view { //NSLog(@"Selected "); self.stationname.text = ((userStation *)view.annotation).name; self.stationsong.text = ((userStation *)view.annotation).song; self.stationartist.text = ((userStation *)view.annotation).artist; [UIView animateWithDuration:0.25 delay: 0.0 options: UIViewAnimationCurveEaseInOut animations:^ { CGRect anim = self.stationinfo.frame; anim.origin.y = 0.0; self.stationinfo.frame = anim; self.stationinfo.backgroundColor = [UIColor redColor]; } completion:^(BOOL finished){ NSLog(@"DONE!"); }]; } - (void) mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view { //NSLog(@"Deselected"); [UIView animateWithDuration:0.25 delay: 0.0 options: UIViewAnimationCurveEaseInOut animations:^ { CGRect anim = self.stationinfo.frame; anim.origin.y = -100.0; self.stationinfo.frame = anim; self.stationinfo.backgroundColor = [UIColor greenColor]; } completion:^(BOOL finished){ NSLog(@"DONE!"); }]; } </code></pre> <p>Your help is much appreciated. Thank you.</p>

    1. COis `stationinfo.frame` being set or changed anywhere else in code?

    2. COis it just me, or is the line with all the `anim` juggling too wordy? You can just do `self.stationinfo.frame.origin.y = -100.0;` or something similar. But that shouldn't be the cause of the problem... Or maybe it is?

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.
