Adding UI Bar Button Items for WebView but app crashing

Question

I've added the following code to my iOS project in XCode. It allows me to add multiple buttons to my UINavigation Controller - the items show fine in the app but when I press the 'Refresh' or 'Back' button the app crashes

What I'm trying to do is create 3 buttons - Refresh, GoBack and GoForward.

The error Im getting says Undeclared selector 'refresh'

// Create the refresh, fixed-space (optional), and profile buttons.
UIBarButtonItem *refreshBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refresh:)];




//    // Optional: if you want to add space between the refresh & profile buttons
//    UIBarButtonItem *fixedSpaceBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
//    fixedSpaceBarButtonItem.width = 12;

UIBarButtonItem *profileBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:self action:@selector(goToProfile)];
profileBarButtonItem.style = UIBarButtonItemStyleBordered;

self.navigationItem.rightBarButtonItems = @[profileBarButtonItem, /* fixedSpaceBarButtonItem, */ refreshBarButtonItem];

Check the declaration/definition of your refresh method.

As per your code action:@selector(refresh:); the refresh method should have atleast one argument.

If your definition of refresh method has not arguments then it should be like action:@selector(refresh);
