How do I add a custom font to a Cocoapod?

Question

I want to use a custom font within a Cocoapod, but I can\'t find anything on using a custom font within a static library. As there is no info.plist file, there is no where to te

If I understand correctly, you are trying to provide a font with your Cocoapod, and you intent the iOS apps which include the pod to be able to use your custom font.

This post_install hook seems to work:

Pod::Spec.new do |s|
  # ...
  s.resources = "Resources/*.otf"
  # ...
  s.post_install do |library_representation|
    require 'rexml/document'

    library = library_representation.library
    proj_path = library.user_project_path
    proj = Xcodeproj::Project.new(proj_path)
    target = proj.targets.first # good guess for simple projects

    info_plists = target.build_configurations.inject([]) do |memo, item|
      memo << item.build_settings['INFOPLIST_FILE']
    end.uniq
    info_plists = info_plists.map { |plist| File.join(File.dirname(proj_path), plist) }

    resources = library.file_accessors.collect(&:resources).flatten
    fonts = resources.find_all { |file| File.extname(file) == '.otf' || File.extname(file) == '.ttf' }
    fonts = fonts.map { |f| File.basename(f) }

    info_plists.each do |plist|
      doc = REXML::Document.new(File.open(plist))
      main_dict = doc.elements["plist"].elements["dict"]
      app_fonts = main_dict.get_elements("key[text()='UIAppFonts']").first
      if app_fonts.nil?
        elem = REXML::Element.new 'key'
        elem.text = 'UIAppFonts'
        main_dict.add_element(elem)
        font_array = REXML::Element.new 'array'
        main_dict.add_element(font_array)
      else
        font_array = app_fonts.next_element
      end

      fonts.each do |font|
        if font_array.get_elements("string[text()='#{font}']").empty?
          font_elem = REXML::Element.new 'string'
          font_elem.text = font
          font_array.add_element(font_elem)
        end
      end

      doc.write(File.open(plist, 'wb'))
    end
  end

The hook finds the user project, and in the first target (you probably can complete this solution by asking CocoaPods to give you the real target) it looks for its Info.plist file(s) (normally there is only one). Finally it looks for the UIAppFonts key of the file, creates it if not found, and fill the array with the font names if they are not already there.
