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

Maybe this:

But why i have to do this?

Was not supposed to use the name of the font? and not the name of the file?

Custom Fonts

In order to add custom font files to your application you need to follow these instructions: 1. Add the font file to the "special" folder: \Files\Special 2. Add the #AppFont attribute for each font file (including the extension): #AppFont: papercuts-2.ttf #AppFont: vermidirouge 1.0.ttf 3. Find...

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
