SearchBar with webview isn't working

I'm creating a Google search with a UIWebView and UISearchBar.

Here's the code from the .m file -

#import "ThirdViewController.h"

@implementation ViewController3

-(IBAction)Googlesearch:(id)sender {
    NSString *query = [googleBar.text stringByReplacingOccurrencesOfString:@" " withString:@"+"];
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.google.co.uk/search?q=%@", query]];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webview3 loadRequest:request];
    [self.view addSubview:webview3];
    [self.view bringSubviewToFront:webview3];
}

@end

.h file -

#import <UIKit/UIKit.h>

@interface ViewController3 : UIViewController <UISearchBarDelegate> {
    IBOutlet UIWebView *webview3;
    IBOutlet UISearchBar *googleBar;
}

-(IBAction)Googlesearch:(id)sender;

@end

Note: The IBactions on both files aren't connected (as I am unsure where to connect it to). But the webview/searchbar are connected to the iboutlets.

How it's suppose to work:

The webview is blank at first, input text in the searchbar, press "search", uiwebview loads Google with the search results of the query entered in the searchbar

Problem/Question:

When I run the app, the UIWebView doesn't load the Google search when I input something into the searchbar.

How do I fix this?

Set the delegates of your UISearchBar object then this method will triggered

-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
       NSString *query = [googleBar.text stringByReplacingOccurrencesOfString:@" " withString:@"+"];
       NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.google.co.uk/search?q=%@", query]];
       NSURLRequest *request = [NSURLRequest requestWithURL:url];
      [webview3 loadRequest:request];
      [self.view addSubview:webview3];
      [self.view bringSubviewToFront:webview3];
}
- (void)viewDidLoad {
   googleBar.delegate = self;
}

Now write your code inside this method.
