Hide UIToolBar and UINavigation and Expand UIWebView? - iOS

Is it possible to hide a UIToolBar and UINavigationBar and to do so with a UITouchGestureRecognizer but at the same time Expand the UIWebView so it takes up the rest of the space? Also to do the same thing in reverse after?

Thanks to all in advance!

To hide top navigation bar use either the navigationBarHidden property or setNavigationBarHidden:animated: method if you want it animated. Similarly, use toolbarHidden property or setToolbarHidden:animated: method for the bottom toolbar. These are part of UINavigationController.

If you want to animate both the toolbars hiding and the UIWebView expanding, wrap the change in size of the UIWebView in a UIView animateWithDuration... method.

Add the gesture recognizer of your choice. For a swipe, create an instance UISwipeGestureRecognizer and add it to your view. Something like this in your viewDidLoad method:

UISwipeGestureRecognizer *swipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe)];
[self.view addGestureRecognizer:swipeGestureRecognizer];

And the swipe handler as something like this:

-(void)handleSwipe{
    if (self.navigationController.navigationBarHidden) {
       [self.navigationController setNavigationBarHidden:NO animated:YES];
        [self.navigationController setToolbarHidden:NO animated:YES];
       [UIView animateWithDuration:0.3 animations:^{
            self.webView.frame = CGRectMake(self.webView.frame.origin.x, self.webView.frame.origin.y, self.webView.frame.size.width, self.webView.frame.size.height - 88);
        }];
    } else {
        [self.navigationController setNavigationBarHidden:YES animated:YES];
        [self.navigationController setToolbarHidden:YES animated:YES];
        [UIView animateWithDuration:0.3 animations:^{
            self.webView.frame = CGRectMake(self.webView.frame.origin.x, self.webView.frame.origin.y, self.webView.frame.size.width, self.webView.frame.size.height + 88);
       }];
    }
}

use

-(void)didTap
{
[self.navigationController setNavigationBarHidden:YES animated:YES];
//remove your tool bar from superview
[toolbar removeFromSuperview];
//code to add ur UIWebView
