iOS Question blank Webview

[Hccsoft]

Hello,

I create a simple layer with buttons, imageviewer with Visual Designer. The same code works with B4A but I don't now why with IOS don't work. I try WebView1.LoadURL and WebView1.LoadHtml. I can see the buttons, the image but the webviewer don't show anything.

Private WebView1 As WebView

Private Sub Application_Start (Nav As NavigationController)
    NavControl = Nav
    Page1.Initialize("Vista_web")
    Page1.Title = "Lectura"

    Page1.RootPanel.LoadLayout("vista_web")
    Page1.RootPanel.Color = Colors.White
    NavControl.ShowPage(Page1)
    WebView1.Initialize("webview1")
    WebView1.LoadHtml("http://www.google.com")
End Sub   

Sub WebView1_Click
   WebView1.LoadURL ("http://www.google.com")
End Sub


End Sub

Thanks

Now works changing
WebView1.LoadHtml("http://www.google.com")
for
WebView1.LoadURL("http://www.google.com")

I exactly copied the lines above into Main. But WebView1 is RED on the lines. What should I do?

I recommend you to start with the beginner's guide: https://www.b4x.com/b4i/documentation.html

The above code is wrong. You need to add WebView with the designer and you shouldn't initialize it in the code.

Erel, I did it like you said. It works now. Thanks. But it doesn't fit the all screen. How can I provide to fit all screen whatever the phone size? Second question is; when pdf file is opened at the web site how can I go back?

Go to desginer. In general script , type
webview1.width = 100%x
webview1.height= 100%y

this will fit all the screen.

Thanks. It is ok now. And when one button at the web page is pressed, user manual (pdf) is opened at the screen. I can not go back. How can I go back? May be when the button is pressed pdf file should be downloaded. How can I provide go back or download pdf file?

Erel, there is a "Hide back button" selection at the properties of Main in the Visual Designer. What is the purpose of "Back button"?

Go to desginer. In general script , type
webview1.width = 100%x
webview1.height= 100%y

It is better to use anchors: https://www.b4x.com/android/forum/threads/b4x-anchors-demonstrated.64112/#content

Please start a new thread for a new question.

Erel, how can I provide go back in webview. And how can I provide downloading pdf file?

Erel, are you saying WebView cannot be added in code with B4I ( it works for me with B4A, but I am getting a blank screen with B4I )
Please clarify

You can add WebView in code. It is simpler to add all views with the designer.

You are right it works .. hopefully for my next app I will try to use the designer, but honestly I have done lots of work to avoid using the designer in order to support different screen resolutions and sizes etc... but I guess the designer got a lot more powerful and if I am not mistaken all of that is handled by the designer now. Is that correct?

 

[Erel]

The designer is built to support different screen sizes. It doesn't happen automatically. You need to set the anchors and use the designer script.
