string - UIWebView crashes loading link from HTML -


if call loadhtmlstring in uiwebview contains external link, try loadhtmlstring again crashes.

html loaded follows:

    nsurl *url = [[nsbundle mainbundle] urlforresource:@"help" withextension:@"html"];     nsstring *text = [nsstring stringwithcontentsofurl:url encoding:nsutf8stringencoding error:nil];      [[self webview] loadhtmlstring:text baseurl:nil];

help.html contain link such as:

example

if tap link loads page. have "home" button on navigation bar calls above code again (loadhtmlstring), crashes app.

any way "trick" uiwebview loading html string again after external link viewed?
