    <p>I'm trying to animate some images. The images are working well on non-retina iPads but their retina counterparts are slow and the animations will not cycle through at the specified rate. The code i'm using is below with the method called every 1/25th second. This method appears to perform better than <code>UIViewAnimations</code>.</p> <pre><code>if (counter &lt; 285) { NSString *file = [[NSBundle mainBundle] pathForResource:[NSString stringWithFormat:@"Animation HD1.2 png sequence/file_HD1.2_%d", counter] ofType:@"png"]; @autoreleasepool { UIImage *someImage = [UIImage imageWithContentsOfFile:file]; falling.image = someImage; } counter ++; } else { NSLog(@"Timer invalidated"); [timer invalidate]; timer = nil; counter = 1; } } </code></pre> <p>I realise there are a lot of images but the performance is the same for animations with less frames. Like i said, the non-retina animations work well. Each image above is about 90KB. Am i doing something wrong or is this simply a limitation of the iPad? To be honest, i find it hard to believe that it couldn't handle something like this when it can handle the likes of complex 3D games so i imagine i'm doing something wrong. Any help would be appreciated.</p> <p><strong>EDIT 1:</strong> </p> <p>From the answers below, I have edited my code but to no avail. Executing the code below results in the device crashing.</p> <p>in <code>viewDidLoad</code></p> <pre><code>NSString *fileName; myArray = [[NSMutableArray alloc] init]; for(int i = 1; i &lt; 285; i++) { fileName = [NSString stringWithFormat:@"Animation HD1.2 png sequence/HD1.2_%d.png", i]; [myArray addObject:[UIImage imageNamed:fileName]]; NSLog(@"Loaded image: %d", i); } falling.userInteractionEnabled = NO; falling.animationImages = humptyArray; falling.animationDuration = 11.3; falling.animationRepeatCount = 1; falling.contentMode = UIViewContentModeCenter; </code></pre> <p>the animation method</p> <pre><code>-(void) triggerAnimation { [falling startAnimating]; } </code></pre>

    1. COWhat if you pre-load all of the UIImage objects into an array instead of loading them on demand while animating?

    2. COI think i've tried that but let me give it a go now and i'll come back...

    3. CO@FogleBird So I tried that. I load up an array with the 280 images in `viewDidLoad`. That works out fine. But when i go to execute the animation using `[falling StartAnimating]` nothing happens for about 7 seconds and then the app crashes. When i run the app in the simulator there is about a 3 second delay and then the animation begins.

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.
