iOS Question B4i scrollview doesn't work

[ConnorMc]

Hello,
i wonder about the difference of scrollview in B4A and B4i.
I wrote a App that connects to a ftp-server, imports a textfile via LoadCSV and shows the rows in table which is the panel of a scrollview.
I created this App for B4A and it works fine.
I did the same for B4i and the scrollview can't be scrolled - it's just fix on the screen of the iPhone and I have no idea why.

What steps are needed to solve this problem?
Do I have to 'Resize' in any way (...although it's not necessary in B4A)?

Here's the B4i-Code (without the ftp connection-data - there's no problem with the ftp-connection)

Thanks for help

Try to add to sv with sv.panel.addview(.... )
and try to set the
sv.contentwidth tp scrollview.width
and sv.contentheight to stg like 3000 and try again.

and if you can post your code between code tags it would be easier for us to understand the code.

 

[ConnorMc]

...it was enough to set sv.contentheight - thank you very much, tufanv.

Next time I'll start playing around with the properties by myself before posting...

What are the 'code tags' for this forum?

 

[tufanv]

sv1.contentheight=100

this is a sample. You can use CODE /CODE with bracelets

Code tags:

...now it's clear:

Sub Signing_Code()
    Msgbox("Thank you guys!")
End Sub
