Keyboard configuration

The following will hide a keyboard nicely;

// Hides a keyboard by use of an invisible button on view
// configure UIButton - Custom, no title & size over touch area
-(IBAction)hideButton:(UIButton *)sender
{
    NSLog(@"Hides the keyboard");
    [self.view endEditing:YES];
}

Here's another way that's less of a cludge; 
 It sets up a gesture for the view

1- Set the .h file to <UIGestureRecognizerDelegate>

2 - Add this to the viewDidLoad to set up the gestureRecognizer
// Tap to hide keyboard
    UITapGestureRecognizer *hideKeyboardTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideTap:)];
    [self.view addGestureRecognizer:hideKeyboardTap];

Probably the BEST way;
1 - Don't forget to set the class as a UITextFieldDelegate
2- Add to viewDidLoad for all textFields - self.textField.delegate = self;
3 - And finally the delegate method
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}



3 - Add this method
- (void)hideTap:(UIGestureRecognizer *)gestureRecognizer
{
    [self.view endEditing:YES];
    NSLog(@"Hides the keyboard");
}
