    <p>I'm trying to animate position of some subviews in a scrollview. I want to create a specific effect as they slide in. I was just using implicit animation by changing the frame on UIView but when they slide in it looks too robotic. So I was hoping to create a bounce effect where they slide in, go a bit to far, and then go back to their intended position, pretty much to how a scrollview looks when it reaches an end, just sort of the opposite.</p> <p>Anyways, I can't get it to animate changing the frame's origin. I'm not sure what I'm missing, because if I switch out what is being animated (make the first //* to /*) it works just fine changing the opacity.</p> <pre><code>- (void)slideInStories; { float scrollViewContentWidth = 0; for (StoryViewController *storyController in storyControllers) { NSMutableArray *animationPoints = [NSMutableArray array]; CGRect viewFrame = storyController.view.frame; //* CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"frame"]; [animationPoints addObject:[NSValue valueWithCGRect:viewFrame]]; viewFrame.origin.x = scrollViewContentWidth - 10; [animationPoints addObject:[NSValue valueWithCGRect:viewFrame]]; viewFrame.origin.x = scrollViewContentWidth; [animationPoints addObject:[NSValue valueWithCGRect:viewFrame]]; /*/ CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"opacity"]; [animationPoints addObject:[NSNumber numberWithFloat:0.75]]; [animationPoints addObject:[NSNumber numberWithFloat:0.0]]; [animationPoints addObject:[NSNumber numberWithFloat:0.75]]; //*/ [animation setValues:animationPoints]; [animation setDuration:4.0]; viewFrame.origin.x = scrollViewContentWidth; scrollViewContentWidth += viewFrame.size.width; [storyController.view.layer setFrame:viewFrame]; [storyController.view.layer setOpacity:1.0]; [storyController.view.layer addAnimation:animation forKey:nil]; } [scrollView setContentSize:CGSizeMake(scrollViewContentWidth, 187.0f)]; } </code></pre>

    1. COHave you tried, just for kicks, animating the `center` instead?

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.
