Using the iPhones Multi-Touch Keyboard Search Button

Question

I have a regular text field on a view and I'd like to make use of the search button on the iPhones keyboard. For the life of me, I can't figure out how to do this. There doesn't seem to be any event exposed that I can wire up that specifically relates to the search button on the keyboard. I've googled around, but I also haven't found anything related to this subject.

Answer 1

Make the keyboard display the blue "Search" button by setting the return key type.

myTextField.returnKeyType = UIReturnKeySearch;

Set the delegate of your text field to your controller and implement the 'textFieldShouldReturn:' method.

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    /* Do some searching here */
    return YES;
}
