    <p>In my program I have six view controllers. To navigate among these view controllers I used UINavigationController.</p> <p>I will explain this issue using two view controllers. In first view controller, I implemented a button action like this</p> <pre><code>- (IBAction)clickSearch:(id)sender{ [self gotoSearch]; } -(void)gotoSearch { NSArray *vc = [self.navigationController viewControllers]; ViewControllerSearch *vcSearch = nil; for (int i = 0; i &lt; [vc count]; i++) { UIViewController *tempVC = [vc objectAtIndex:i]; if ([tempVC isKindOfClass:[ViewControllerSearch class]]) { vcSearch = [vc objectAtIndex:i]; break; } } if (vcSearch) { //If exists inside stack the pop [self.navigationController popToViewController:vcSearch animated:YES]; } else { //If not exists inside stack push ViewController3 ViewControllerSearch *vc3New = [self.storyboard instantiateViewControllerWithIdentifier:@"vcsearch"]; [self.navigationController pushViewController:vc3New animated:YES]; vc3New = nil; } } </code></pre> <p>second view controller has a button and that button action is also implemented as above.</p> <p>if I move to second view controller from first view controller ,memory increasing.(its ok)</p> <p>if I move to first view controller from second view controller, memory level not changing.</p> <p>again I move to second view controller from first view controller ,memory increasing.you can see it in this image.</p> <p>(memory is not reducing)How can I reduced memory? <img src="https://i.stack.imgur.com/7GiyQ.png" alt="enter image description here"></p> <p>first time first to second : NSArray *vc has one object (first VC)</p> <p>second to first : NSArray *vc has two object (first VC,and second VC)</p> <p>now im in first view controller.now im click to move second view controller : NSArray *vc has only one object (first VC).second vc missing.and increasing memory (i think it for new second vc)</p>

    1. COjust do one thing NSLog every time NSArray *vc=[self.navigationController viewControllers]; and check what it has in stack in each navigation

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.
