显示为问号的FontAwesome图标

Question

I am trying to set the button text for the following :

The first step I followed is to include the font file in the project. I then referred it in the Info.plist.
I copied the icon from the cheatsheet :

Then I set the font for the button in IB as follows :

As a result, I get a question mark on the button (both in IB and on running).

Just for cross checking, I set some other icon instead of this. It worked fine.

Where could the mistake be ?

Answer 1

In IB set only the font name and size , in code use something like this

self.backBu.setTitle(String(format:"%C",0xf053), for: .normal);

replace f053 with unicode that you want , also make sure that target memberShip is checked for the font resource and you add it to info.plist

Answer 2

You are using the wrong font. The one you want is FontAwesome5FreeSolid ( fa-solid-900.ttf ).

This works fine on my machine:

    let s = "\u{f362} Convert"
    let ss = NSAttributedString(string: s, attributes: 
        [.font : UIFont(name:"FontAwesome5FreeSolid", size:17)!])
    let b = UIButton(type: .system)
    b.frame = CGRect(x: 40, y: 40, width: 200, height: 200)
    b.setAttributedTitle(ss, for: .normal)
    self.view.addSubview(b)

Result:
