iOS自定义字体（ttf和otf）

• 自定义字体有两个方法

• 方法1：

  • plist 文件中配置

  • 参考：

• 方法2：

  • 直接读取字体资源文件

• 通过字体文件初始化字体，如下方法：

    func customFontWithPath(name:String ,ofType:String ,size:CGFloat) -> UIFont {

        guard let path = Bundle.main.path(forResource: name, ofType: "ttf")  else {
            assert(false, "Warning :字体文件未找到")
            return UIFont.systemFont(ofSize: size)
        }

        let fontUrl = NSURL(fileURLWithPath: path)
        let fontDataProvider = CGDataProvider(url: fontUrl)
        let fontRef = CGFont(fontDataProvider!)
        CTFontManagerRegisterGraphicsFont(fontRef!, nil)

        let fontName:String = "\(fontRef?.postScriptName ?? "" as CFString)"
        let font = UIFont(name: fontName, size: size) ?? UIFont.systemFont(ofSize: size)

        return font
    }

    label.textAlignment = .center
    self.view.addSubview(label)
    label.snp.makeConstraints {
        $0.height.equalTo(200)
        $0.width.equalToSuperview()
    }

        $0.width.equalToSuperview()
    }

    // - Path
    /// :  ttf create font by path
    label = UILabel()
    label.backgroundColor = UIColor.white
    label.text = "zhangdong，你好！"
    label.textAlignment = .center
    label.font = customFontWithPath(name: "STXINWEI", ofType: "tff", size: 20)
    self.view.addSubview(label)
    label.snp.makeConstraints {
        $0.top.equalTo(600)
        $0.height.equalTo(200)
        $0.width.equalToSuperview()
