{
 NSArray *vc=[self.navigationController viewControllers];

    ViewControllerSearch *vcSearch=nil;

    for (int i=0; i<[vc count]; i++)
    {
        UIViewController *tempVC=[vc objectAtIndex:i];
        if([tempVC isKindOfClass:[ViewControllerSearch class]])
        {
            vcSearch=[vc objectAtIndex:i];
            break;
        }
    }

    if(vcSearch)
    {

        [self.navigationController popToViewController:vcSearch animated:YES];
    }
    else
    {

        ViewControllerSearch *vc3New= [[ViewControllerSearch alloc]initWithNibName:@"ViewControllerSearch" bundle:[NSBundle mainBundle]];
        [self.navigationController pushViewController:vc3New animated:YES];

how can i fixed this error?please give me idea.

回答1:

Are you certain your Nib is called 'ViewControllerSearch.xib'?

Also you don't need to nil out vc3New - in fact you probably shouldn't.

UPDATED

...to load from a storyboard, as mentioned in the comment, you need to do something like this:

UIStoryboard* storyBoard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; 
ViewControllerSearch* controller = [storyBoard instantiateViewControllerWithIdentifier:@"ViewControllerSearch"];

1) Make to sure the storyboard identifier matches what you've named it 2) Make sure you've set/used the correct identifier, in the storyboard, for your controller
