iOS Question [B4X] Iterate return error with custom font

[AymanA]

Hi All,

I am having a problem that I might be doing something wrong but can not spot that!

If I use the code below to set custom font to single BRB4XFloatTextField it is working fine:

private ACT as BRB4XFloatTextField
ACT.TextField.font  = Font.CreateNew2("neosansarabic", 14)

However if I do this it fails:

For Each v As BRB4XFloatTextField In Root.GetAllViewsRecursive
    v.TextField.font  = Font.CreateNew2("neosansarabic", 14)
Next

And I receive this error stack:

Error occurred on line: 952 (B4XMainPage)
[<UIScrollView 0x7faa82868400> valueForUndefinedKey:]: this class is not key value coding-compliant for the key bi.

I tried clean project but nothing changed, I am receiving the same error.

Hi,
are there only BRB4XFloatTextField in your layout? Otherwise Root.GetAllViewsRecursive might get some view that can not be casted to a BRB4XFloatTextField.

Custom views are not views. Read this: [B4X] How to get <custom view here> from <CLV or any other container>
