WKWebView弹出Alert和Confirm

wkwebview弹框的代理有两种Alert和Confirm(是不是有很多小伙伴们知道alert,不知道还有一个confirm啊)

- (void)webView:(WKWebView*)webView runJavaScriptAlertPanelWithMessage:(NSString*)message initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void (^)(void))completionHandler {

    NSLog(@"runJavaScriptAlertPanelWithMessage");

    completionHandler();

}

- (void)webView:(WKWebView*)webView runJavaScriptConfirmPanelWithMessage:(NSString*)message initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void (^)(BOOL))completionHandler {

    completionHandler(NO);

}

注:代理里面的block回调的方法必须实现,主要作用是执行完弹框之后dealloc的时候告知wkwebview
