Have you ever been frustrated that the back button on the navbar doesn't go back in navigation, but to the previous screen altogether? Here's a quick way to solve it: Step 1) In the -(void)viewWillAppear method, add this code: UIBarButtonItem backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStylePlain target:self action:@selector(navLeftTap)]; self.navigationItem.leftBarButtonItem = backButton; Step 2) Outside the curly braces (right after the viewWillAppear method finishes is fine), add this code: -(void)navLeftTap { [BT_debugger showIt:self message:@"navLeftTap"]; if([self.webView canGoBack]){ [self.webView goBack]; } else [super navLeftTap]; } Title Comments Here's a useful tip for people using the Custom URL plugin.
