iphone how to remove modal uiviewcontroller from memory
- by Scott Pendleton
I have a root UIViewController which has a property called webView. WebView is a UIViewController with a XIB that contains a UIWebView. From my root view I modally (is there any other way?) load the webView ViewController and set its URL, always to the same page.
I discovered that if, after loading the webView, I used its default Web page to navigate to another Web page, and then closed the webView and returned to the root controller -- AND THEN reopened the webView, that the webView was not showing the default page but rather the page I navigated to, which means the webView ViewController never got destroyed and removed from memory. This strikes me as very bad.
So in the root ViewController, I added this code under viewWillAppear:animated --
if (self.webView != nil) {
self.webView = nil)
}
Is that sufficient? Is there a better way?
