I am having some trouble getting a WKWebView in iOS 8 to display an alert dialog that is called from Javascript. After creating a standard WKWebView and loading an HTML file, I have a button on the page that creates a simple alert with some text. This works in UIWebView and in Google Chrome/Safari, but does not appear to be working in WKWebView. Any help is appreciated.

My setup is as follows:

WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init];

config.allowsInlineMediaPlayback = YES;

config.mediaPlaybackRequiresUserAction = false;

_wkViewWeb = [[WKWebView alloc] initWithFrame:_viewWeb.frame config];

_wkViewWeb.scrollView.scrollEnabled = NO;

NSString *fullURL = @file://.../TestSlide.html;

NSURL *url = [NSURL URLWithString:fullURL];

NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10];



[_wkViewWeb loadRequest:request];

The html has the following function:

<SCRIPT Language=JavaScript>

function alertTest() {

    alert(Testing Alerts);

}

</SCRIPT>

And a button:

<b>Test Alerts: <input type=button value=Alert Popup onclick=alertTest()><br></b> <br>

This setup works in UIWebView and in regular browsers, but does not work in WKWebView. Am I missing something in the configuration? Should I be using one of the WK delegates to control the alert/confirm dialog behavior? Thank you.
