    <p>Base on the debug log you gave I got a reason by searching:<br> <strong><code>MainSettingClass</code> instance that you pushed before can neither be repushed to the array on navigationController again, nor be presented modally. You should create a new MainSettingClass instance and present it, just like the second code snippet.</strong> </p> <p><a href="https://stackoverflow.com/questions/7429014/application-tried-to-present-modally-an-active-controller">HERE</a> is a relate question that mentioned <code>Application tried to present modally an active controller</code>. :)</p> <pre><code>-(void)popToMainMenuAnimated:(BOOL)animated { UIViewController *element; for(element in self.viewControllers) { if([element isKindOfClass:[MainSettingClass class]]) { self.modalTransitionStyle = UIModalTransitionStylePartialCurl; [self presentModalViewController:element animated:YES]; break; } } } </code></pre> <p>But why not <code>load</code> the <code>Main Menu</code> instead of <code>pop</code>?</p> <pre><code>-(void)loadMainMenuAnimated:(BOOL)animated { MainSettingClass * mainMenuViewController = [[[MainSettingClass alloc] init] autoreleased]; [mainMenuViewController.view setFrame:CGRectMake(0.0f, 0.0f, 320.0f, 480.0f)]; // ... self.modalTransitionStyle = UIModalTransitionStylePartialCurl; [self presentModalViewController:mainMenuViewController animated:YES]; } </code></pre> <hr> <p>And the code you show has some mistakes:</p> <pre><code>self.modalTransitionStyle= UIModalTransitionStylePartialCurl; [self popToViewController:element animated:YES]; </code></pre> <p><code>self.modalTransitionStyle= UIModalTransitionStylePartialCurl;</code> if you set this one, you need use</p> <pre><code>[self presentModalViewController:yourViewController animated:YES]; </code></pre> <p>not </p> <pre><code>[self popToViewController:element animated:YES]; </code></pre>

    1. COI did the changes as suggested, But this is causing my app to crash. Previosly only transition attribute was not obeyed and irrespective of what style I choose its always transition in default manner.

    2. COTransition is happening correctly with [self popToViewController:element animated:YES]; But I want transition not to be of deafault but of UIModalTransitionStylePartialCurl. When I try your changes: [self.modalTransitionStyle= UIModalTransitionStylePartialCurl; [self presentModalViewController:element animated:YES]; App crashes.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
