Question

I have a bottom toolbar button that contains a button which opens a UIWebView *webView

- (IBAction)rebateWebView:(id)sender {
       [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]]];
}

Now, after the webView loads I want to change the title of the button and when the button is tapped again I want the webView to disappear or, in essence, reload the firstviewcontroller.

I know how to change the title and have that working. My biggest problem is dropping the webView. I just can’t wrap my head around it.

Answer 1

[self.webView removeFromSuperView]; will remove your webView from the super view, which is almost certainly your view controller’s self.view.

Then depending on whether you still need it or not you may want to nil it out and/or release it if you are not using ARC.

If you are trying to “reload” the view controller instead (which is completely different from dropping self.webView, you can call [self viewWillDisappear:NO]; [self viewWillAppear:NO]; if what you need is in those methods.

Edit

Jim’s suggestion is also valid if you may want to re-show that self.webView in the future:

self.webView.hidden = YES to hide
self.webView.hidden = NO to show
