提问by Mina Dawoud
Is it possible to hide a UIToolBarand UINavigationBarand to do so with a UITouchGestureRecognizerbut at the same time Expand the UIWebViewso it takes up the rest of the space?
Also to do the same thing in reverse after?

To hide top navigation bar use either the navigationBarHiddenproperty or setNavigationBarHidden:animated:method if you want it animated. Similarly, use toolbarHiddenproperty or setToolbarHidden:animated:method for the bottom toolbar. These are part of UINavigationController.
要隐藏顶部导航栏，如果您希望它具有动画效果，请使用navigationBarHidden属性或setNavigationBarHidden:animated:方法。同样，使用底部工具栏的toolbarHidden属性或setToolbarHidden:animated:方法。这些是UINavigationController.
If you want to animate both the toolbars hiding and the UIWebViewexpanding, wrap the change in size of the UIWebViewin a UIView animateWithDuration...method.
如果要同时为工具栏隐藏和UIWebView扩展设置动画，请将 的大小更改包装UIWebView在一个UIView animateWithDuration...方法中。
Add the gesture recognizer of your choice. For a swipe, create an instance UISwipeGestureRecognizerand add it to your view. Something like this in your viewDidLoadmethod:
添加您选择的手势识别器。对于滑动，创建一个实例UISwipeGestureRecognizer并将其添加到您的视图中。在你的viewDidLoad方法中是这样的：
UISwipeGestureRecognizer *swipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipe)];
[self.view addGestureRecognizer:swipeGestureRecognizer];
And the swipe handler as something like this:
和滑动处理程序是这样的：
-(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);
}];
}
}
