Hi everyone.
I'm trying to use these fonts (attached), i put this in "#Region Project Attributes"

B4X:
    #AppFont: futuralt-bold.ttf
    #AppFont: futuralt-book.ttf
    #AppFont: futuralt-bookoblique.ttf

i put the .ttf in the Special folder, and did like so:


B4X:
    lblTitleLastOps.Font = Font.CreateNew2("FuturaLTBold", 30)

I got this error:

B4X:
Application_Start
Application_Active
Error occurred on line: 51 (Home)
Object was not initialized (UIFont)

actually following this tutorial took me to having the problem.

Because 4th step the tutorial says to use the font name without spaces, and I did (I used the name showed in the Windows title bar when you open a .ttf file) and It didn't work.
To get it working, in this case only, I had to use the filename (apparently), like angel_ suggested, even if I don't know why, because all the other times it worked using the font name, not the filename.

You can use a snippet (for example, in Application_Start), to understand, what IOS expects.

B4X:
    Dim no As NativeObject
    Dim l1 As List = no.Initialize ("UIFont").GetField ("familyNames")
    For Each s1 As String In l1
        Log (s1)
        Dim l2 As List = no.Initialize ("UIFont").RunMethod ("fontNamesForFamilyName:", Array (s1))
        For Each s2 As String In l2
           Log ("   " & s2)
        Next
    Next

In your case you will see for family name Futura LT following font names:
B4X:
   FuturaLT-Book
   FuturaLT-BookOblique
   FuturaLT-Bold
