    <p>I'm doing some testing with the simple Xcode page base application using Arc.</p> <p>I'm loading a uiwebview with in the dataviewcontroller and I've been testing the activity with Instruments, the memory usage keeps going up and up as i scroll the pages and it looks like the previous pages are never release from memory. </p> <p>here are the changes I made to the default template. I've modified the model to run for 240 pages rather than the 12 defaults.</p> <p>In the dataViewController, I'm adding a uiwebview programatically and loading request to google and add the webview to the controller view.</p> <p>Memory usage starts at about 20Mb and eventually gets to over 70Mb and then it crashes.</p> <p>Anybody know where I'm going wrong? How can I release the views to free up memory?</p> <p>amended code below:</p> <p>DataViewController.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface RXBDataViewController : UIViewController&lt;UIWebViewDelegate&gt; { UIWebView *pageContent; } @property (strong, nonatomic) IBOutlet UILabel *dataLabel; @property (strong, nonatomic) id dataObject; @end </code></pre> <p>DataviewController.m</p> <pre><code>#import "RXBDataViewController.h" @interface RXBDataViewController () @end @implementation RXBDataViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. pageContent = [[UIWebView alloc] initWithFrame:CGRectMake(8, 30, 260, 350)]; pageContent.userInteractionEnabled = NO; [pageContent setDelegate:self]; [pageContent loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com/"]]]; [self.view addSubview:pageContent]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; self.dataLabel.text = [self.dataObject description]; } @end </code></pre> <p>Thanks in advance for suggestions.</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.
