I am facing this error, when i come back to my old View after visiting a new View (On click of Back Button on navigationBar)

First: On click of searchBar, i am visiting a new View which contains searchBar in place of UINavigationBar (UINavigationBar is hidden in new View)..

Here is code snippet, which navigates to new View after clicking searchBar...

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar 
{
    BTSViewController *Obj = [[BTSViewController alloc]  initWithNibName:@"BTSViewController" bundle:nil];
    [self.navigationController pushViewController:Obj animated:NO];
}

Second: on click of cancel button in searchBar i am going back to my previous View & in viewWillDisappear method i am doing setNavigationBarHidden:NO

Here is code snippet, which comes back to previous View after clicking Cancel button in UISearchBar...

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
    [self.navigationController popViewControllerAnimated:NO];
}

I am navigated to my previous view but UINavigationBar is hidden and shows Unbalanced call error... in my Log.

Thanks in advance !!

  • post the code of your previous viewcontroller's `viewDidLoad:` method because in `viewDidLoad:` method not all of the fancy animations have already been finished so your app crahsed... – Paras Joshi May 01 '13 at 11:43

Here you get this type of error with Two Reasons.

  1. If you pushed more then one UIViewController at a same time.

  2. In your ViewController.m's viewDidLoad: method in not all of the fancy animations have already been finished so your app crahsed

I suggest If you add some Fancy Animations code in viewDidLoad: method then just replace that type of code from viewDidLoad: to viewDidAppear: and Also maintain Queue of your viewControllers..

i hope this answer helpful to you...
