    i have a simple app which is uses webview to display a html page, in Debug build the html page appears fine but in release build, the webview is blank (white).

    i have already
    -cleaned up safari history in case that was causing problem.
    -placed a test button to reload the page instead of at app start.
    -checked if file exists or not, and it does exists.

    here is the code i am using to load the html page.

    WebView1.LoadUrl("file://" & File.Combine(File.DirAssets,"1.htm"))

    placed under
    Sub Application_Start

    Use LoadHtml
    example :

    LoadHtml is for loading HTML string not a file.

    Loadhtml works but very slow, my html page takes 3-4 secs to appear. dont know how to fix it, i have searched the forum and other are also having this problem.

    LoadHtml just calls the native UIWebView API that loads an html string. Make sure that your string doesn't reference any non-local resources.

    my html page has lots of non-english Unicode character and the take time to render if loading by string, but not in case of loading the html by file in debug mode. i am not referencing non-local files, all the images and css are added to the files tab.

    some other user suggested to copy the html to temp folder and then load it, is it fine to do it?

    My page do have two external links, one opens a link and other link is a mailto to send me a email. is it fine?

    Can you post a Obj-C code to load a html file in webview?
