Dismiss keyboard when user taps Mapview

I have a UITextView in my Navbar that is acting as a search box. I would like to dismiss the associated keyboard when the user taps below the text box - namely on the MKMapView. However I can't figure out how to do this since it doesn't look like I can intercept touches from the mapview.

I have looked at a number of solutions, but none seem to work for my case as far as I can tell. Does anyone have a simple way to do this? I am a bit of a noob, so please let me know if I am not providing some releva开发者_开发问答nt information, and please provide a few lines of example code in your answer if you can - I am still a bit shaky with terminology. Thanks!

Assuming

UITextView *textView; 

Then you can dismiss the keyBoard by sending:

[textView resignFirstResponder];

Also: you may prefer to use a UISearchBar and set it as the navigationItem.titleViewof the ViewController. This offers some nice delegate methods.

I know this is an old one but in case anyone else is looks for a simple answer to this, here's my solution to get a "mapView" to resignFirstResponder. This will work in a similar way to the Google Maps app on the iphone, where a semi transparent box appears when you start editing the search text field.

Firstly you need to make your view controller a UISearchBarDelegate

@interface ViewControllerName <UISearchBarDelegate>

// your code here

@end

Then implement the following delegate methods:

@implementation ViewControllerName

// your code here

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
 darkBg = [[UIControl alloc] initWithFrame:CGRectMake(0, 244, 320, 300)];
 [darkBg setBackgroundColor:[UIColor blackColor]];
 [darkBg addTarget:nil action:@selector(hideKeyboard) forControlEvents:UIControlEventTouchDown];
 [darkBg setAlpha:0.8];
 [UIView beginAnimations:@"slideup" context:nil];
 [darkBg setCenter:CGPointMake(160, 194)];
 [self.view addSubview:darkBg];
 [UIView commitAnimations];
}

- (void)hideKeyboard {
 [UIView beginAnimations:@"fadeou" context:nil];
 [darkBg setAlpha:0.0];
 [UIView commitAnimations];
 [addressField resignFirstResponder];
 [darkBg performSelector:@selector(removeFromSuperview) withObject:nil afterDelay:1.0];
 [darkBg release];
}

A less hacky solution is to rely on one of the MKMapView delegate methods to dismiss the keyboard

- (void) mapView:(MKMapView *)mapView regionWillChangeAnimated:(BOOL)animated {
  if ([self.textField isFirstResponder]) {
    [self.textField resignFirstResponder];
  }
}
