    <p>I'm a newbie and I need some help.</p> <p>I want to display a popup image over a given UIView, but I would like it to behave like the UIAlertView or like the Facebook Connect for iPhone modal popup window, in that it has a bouncy, rubbber-band-like animation to it.</p> <p>I found some code on the net from someone who was trying to do something similar. He/she put this together, but there was no demo or instructions. </p> <p>Being that I am so new, I don't have any idea as to how to incorporate this into my code.</p> <p>This is the routine where I need the bouncy image to appear:</p> <pre><code>- (void) showProductDetail { . . . //////////////////////////////////////////////////////////////////////// // THIS IS A STRAIGHT SCALE ANIMATION RIGHT NOW. I WANT TO REPLACE THIS // WITH A BOUNCY RUBBER-BAND ANIMATION _productDetail.transform = CGAffineTransformMakeScale(0.1,0.1); [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; _productDetail.transform = CGAffineTransformMakeScale(1,1); [UIView commitAnimations]; } . . . } </code></pre> <p>This is the code I found:</p> <pre><code>float pulsesteps[3] = { 0.2, 1/15., 1/7.5 }; - (void) pulse { self.transform = CGAffineTransformMakeScale(0.6, 0.6); [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:pulsesteps[0]]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(pulseGrowAnimationDidStop:finished:context:)]; self.transform = CGAffineTransformMakeScale(1.1, 1.1); [UIView commitAnimations]; } - (void)pulseGrowAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:pulsesteps[1]]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(pulseShrinkAnimationDidStop:finished:context:)]; self.transform = CGAffineTransformMakeScale(0.9, 0.9); [UIView commitAnimations]; } - (void)pulseShrinkAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:pulsesteps[2]]; self.transform = CGAffineTransformIdentity; [UIView commitAnimations]; } </code></pre> <p>Thanks in advance for any help that you can give me.</p>

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.
