Hiding the keyboard when a UITextField loses focus

Question

I saw some topics on how to reject the keyboard when a UITextField loses focus, but it didn’t work for me, and I don’t know how to do it. "TouchhesBegan: withEvent:" in the following code is never called. Why?

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    UITouch *touch = [[event allTouches] anyObject];
    if ([self.textFieldOnFocus isFirstResponder] && [touch view] != self.textFieldOnFocus) {
        [textFieldOnFocus resignFirstResponder];
    }
    [super touchesBegan:touches withEvent:event];
}

PS: This code has been pasted into a view controller that has a UITableView. UITextField is in the cell from this table.

So my opinion is this: this method is not called, because the touch happens on a UITableView from my ViewController. So, I think that I will have to subclass UITableView to use this method, as I saw on other Threads, but it might be easier.

could you help me? Many thanks!
