    <p>I have a View Controller where I have setup a UIImageView and want to animate it with QuartzCore in Xcode - I built the UIImage to live in an Image View that rotates. This rotates fine when I was testing it in it's own project but now that I am pulling it into my current working project it adds the Image View but does not animate? No idea why? Any ideas?</p> <p>I don't have any errors or Warnings and it's the same code that was working in a separate project? I also have the QuartzCore library added and #imported</p> <pre><code>- (void)viewDidLoad { //Setup Image View UIImage *image = [UIImage imageNamed:@"record01.png"]; UIImageView *imgView = [[UIImageView alloc] initWithImage:image]; [imgView setFrame: CGRectMake(0, 0, image.size.width, image.size.height)]; [imgView setCenter:(CGPoint){160,160}]; [self.view addSubview:imgView]; //Animate Image View CABasicAnimation *fullRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"]; fullRotation.fromValue = [NSNumber numberWithFloat:0]; fullRotation.toValue = [NSNumber numberWithFloat:2 * M_PI]; fullRotation.duration = 1.5; fullRotation.repeatCount = HUGE_VALF; [imgView.layer addAnimation:fullRotation forKey:@"fullRotation"]; [super viewDidLoad]; // Do any additional setup after loading the view. } </code></pre> <p>Console for po [[UIApp keyWindow] recursiveDescription]</p> <pre><code> | | &lt;UIImageView: 0x984a9f0; frame = (-6.5 -6.5; 333 333); opaque = NO; userInteractionEnabled = NO; layer = &lt;CALayer: 0x984a040&gt;&gt; (lldb) po 0x984a040 (int) $2 = 159686720 &lt;CALayer:0x984a040; position = CGPoint (160 160); bounds = CGRect (0 0; 333 333); delegate = &lt;UIImageView: 0x984a9f0; frame = (-6.5 -6.5; 333 333); opaque = NO; userInteractionEnabled = NO; layer = &lt;CALayer: 0x984a040&gt;&gt;; contents = &lt;CGImage 0x9843560&gt;; rasterizationScale = 2; contentsScale = 2&gt; (lldb) </code></pre>

    1. CO`[imgView setFrame: (CGRect){{0,0},image.size}];`: this syntax is bad form, but entirely unneeded. `UIImageView` will default to the size of the image. Preferred (but unneeded): `CGRectMake(0, 0, image.size.width, image.size.height);`)

    2. COThanks @bshirley - I changed the code to reflect that. Any idea on why it's not animating for me?

    3. COI disagree that using C99 syntax is bad form. In fact I use it exclusively. Maybe it's just a difference of opinion? Why is `CGRectMake` preferred?

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.
