    <p>I have an iPad app, which is children's book. You navigate from one page to the next by calling this action, which essentialy fades out the current page and fades in the next page, then fills the three stack UIImageViews with the next row of the NSArray, so it's prepared to complete the action for the next page:</p> <pre><code>-(void)delayedMethod{ [leftButton setAlpha:1]; [pageImageNext setAlpha:0]; [pageImage setAlpha:1]; [pageImageBack setAlpha:1]; NSString *imageExtension = @".jpg"; NSString *audioExtension = @".wav"; if (activePage == thePages.count/3) { activePage = 1; } else { activePage = activePage + 1; } NSInteger row = 0; if(activePage == 0) { row = activePage; } else { row = ((activePage) * 3); } [leftButton setAlpha:1]; pageImageBack.image = [UIImage imageNamed:[NSString stringWithFormat:@"%@%@", [thePages objectAtIndex:row+0], imageExtension]]; pageImage.image = [UIImage imageNamed:[NSString stringWithFormat:@"%@%@", [thePages objectAtIndex:row+1], imageExtension]]; pageImageNext.image = [UIImage imageNamed:[NSString stringWithFormat:@"%@%@", [thePages objectAtIndex:row+2], imageExtension]]; [UIImageView beginAnimations:NULL context:NULL]; [UIImageView setAnimationDuration:.5]; // you can set this to whatever you like /* put animations to be executed here, for example: */ [leftButton setAlpha:0]; [rightButton setAlpha:0]; [leftButton setAlpha:1]; [rightButton setAlpha:1]; leftButton.hidden = NO; /* end animations to be executed */ [UIImageView commitAnimations]; // execute the animations listed above [imageExtension release]; } </code></pre> <p>The NSArray is loaded in this action, which is called in the ViewDidLoad:</p> <pre><code>-(void)loadPages { thePages = [[NSArray alloc] initWithObjects: // How many stacked images do we need to get fade in and outs? Also add column fo @"page0",@"page0",@"page1", @"page0",@"page1",@"page2", @"page1",@"page2",@"page3", @"page2",@"page3",@"page4", @"page3",@"page4",@"page5", @"page4",@"page5",@"page6", @"page5",@"page6",@"page7", @"page6",@"page7",@"page8", @"page7",@"page8",@"page9", @"page8",@"page9",@"page10", @"page9",@"page10",@"page11", @"page10",@"page11",@"page12", @"page11",@"page12",@"page13", @"page12",@"page13",@"page14", @"page13",@"page14",@"page15", @"page14",@"page15",@"page16", @"page15",@"page16",@"page17", @"page16",@"page17",@"page18", @"page17",@"page18",@"page19", @"page18",@"page19",@"page20", @"page19",@"page20",@"page21", @"page20",@"page21",@"page22", @"page21",@"page22",@"page23", @"page22",@"page23",@"page24", @"page23",@"page24",@"page25", @"page24",@"page25",@"page26", @"page25",@"page26",@"page27", @"page26",@"page27",@"page27", nil]; } </code></pre> <p>It all works just fine until about the 10-12th page when I start to get memory warnings in the console and usually a crash.</p> <p>I am pretty sure it is just a matter of releasing the three large UIImageViews at the right time, but I can't figure out when...I've tried a number of different spots in the code.</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.
