Binding a Function to "Search" button in Keyboard

I have an UITextField to search the word that typed there. I set the returnKeyType as UIReturnKeySearch. But I couldn't figure how to bind a function that I created, to the "Search" button at the keyboard. 

self.searchWord.returnKeyType=UIReturnKeySearch;

How can I do that? Thanks.

If I'm understanding correctly you need to implement the UITextfield delegate:

In your header file

@interface MyViewController : UIViewController <UITextFieldDelegate>

in viewDidLoad

- (void)viewDidLoad {
    [super viewDidLoad];
    self.searchTextField.delegate = self;
}

Then implement the delegate method.

- (BOOL)textFieldShouldReturn:(UITextField *)aTextfield {        
    // Only do search when user hits return key on the search textfield.
    if ([aTextfield isEqual:self.searchTextField]) {
        // Method that does the search.
        [self doSearch];
    }

    return YES;
}
