How to check current UIViewController on navigation stack

Question

I am trying to figure out which UIViewController is currently on the top of the UINavigationController stack, I am passing these values over to my NSArray viewCtrls, when I log the top UIViewController I get this.

<SearchViewController: 0x1457c550>

So this is the code I am trying to use to figure out which UIViewController is at the top of the UINavigationStack

NSArray *viewCtrls = navcontroller.viewControllers;
UIViewController *vCtrl = [viewCtrls objectAtIndex:[viewCtrls count]-1];
            
NSLog(@"%@", vCtrl);
            
if ([vCtrl isKindOfClass:SearchViewController]) {
    NSLog(@"yes");
} else {
    NSLog(@"no");
}

However I am getting this error on the first line of the if statement.

Use of undeclared identifier 'SearchViewController'

I would like to know how I am supposed to declare the identifier? this is being called from a NSObjectClass, so I need to pass a parameter of self from the UIViewController that called this NSObjec class? or is there a better way of doing it?

Answer 1

You want [vCtrl isKindOfClass:[SearchViewController class]]
