    <p>I have an app with tabbar and webview. I'm trying to make the app come back to default url each time user taps the bar. Right now I'm intercepting taps and launching a method, however it's not affecting my webview (it's not loading the page). The method works properly when called from the class, but not when it's called from my app delegate, where I'm intercepting taps.</p> <p>I suspect it's something with the way I create the SecondViewController object that it's not pointing to the webview, but I have no clue what I'm doing wrong.</p> <p>Here is the code:</p> <p>Second view header (where the WebView is located)</p> <pre><code>@interface SecondViewController : UIViewController { IBOutlet UIWebView *secondView; } - (void) goToPage; </code></pre> <p>Second view implementation</p> <pre><code>#import "SecondViewController.h" @implementation SecondViewController - (void)awakeFromNib { [self goToPage]; } - (void) goToPage { NSLog(@"go to page"); NSString *newURL = [NSString stringWithFormat:@"http://pageurl"]; [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]]; } </code></pre> <p>My app delegate, where I call the SecondViewController class method:</p> <pre><code>#import "RedDragonAppDelegate.h" #import "SecondViewController.h" @implementation RedDragonAppDelegate @synthesize window; @synthesize rootController; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after application launch [window addSubview:rootController.view]; } - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { NSLog(@"didSelectViewController %d", rootController.selectedIndex); SecondViewController * sv = [[SecondViewController alloc] init]; if (rootController.selectedIndex == 0){ //NSLog(@"if in didSelectViewController 0"); } else if (rootController.selectedIndex == 1) { //NSLog(@"if in didSelectViewController 1"); [sv goToPage]; } } </code></pre> <p>Thanks fot your help!</p>

    1. COI'm assuming that you are in fact seeing `go to page` in your log, so you know `goToPage` is being called. Are the original URL and the new URL the same? Does the call from `goToPage` work if you replace `newURL` (in `NSURL URLWithString:`) with, e.g., `@"http://www.google.com/"`?

    2. COhaha I wouldn't be posting it if I didn't check the obvious :) Indeed, I know that the function is being executed and I'm certain that new URL is not being loaded. I did figure out half of the problem though. When I changed [ptr goToPage]; to [self goToPage]; it started working BUT... I still have to call it from another class. When I create the object like this: SecondViewController *ptr = [[SecondViewController alloc] init]; the function gets executed, however the webview is not activated. :( Any idea why?

    3. COHow is `secondView` being set? Maybe there's a retain/release/autorelease issue?

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.
