Does UIWebView leak memory?

Question

If your iPhone app uses a UIWebView, and loads many pages with large images, you may find that you are leaking memory. Can this be resolved?

Answer 1

Try adding

[webView loadHTMLString: @"" baseURL: nil];

right before you release the webview. For a leak in 4.2.1 relating to displaying a PDF in a UIWebView this solves most of the leak problems for me.

Answer 2

It is a known problem.

There isn't a lot you can do. One option in to "intercept" the html try to truncate parts that you don't need. Obviously, this won't likely work for a general purpose webview.

In the meantime, you may just have to wait for an update from Apple.
