我正在通过Swift制作iOS应用。我想在一个地方管理所有字体大小及其样式,如下面的HTML代码。在下面的代码中,我必须调整页面中所有字体的大小才会改变SeekBar seekBar = (SeekBar) view.findViewById(R.id.seek);
。
body{font-size}
我想知道如何在iOS开发中管理APP中的所有字体。

您可以执行以下操作:
至少你可以得到一些关于如何实现这一目标的想法:)
extension UIFont {
struct CustomFont {
private var fontFamily: String!
static let defaultFontSize: CGFloat = 12
func Light(withSize size: CGFloat = CustomFont.defaultFontSize) -> UIFont? {
return UIFont(name: "\(fontFamily)-Normal", size: size)
}
func Normal(withSize size: CGFloat = CustomFont.defaultFontSize) -> UIFont? {
return UIFont(name: "\(fontFamily)-Normal", size: size)
}
func Bold(withSize size: CGFloat = CustomFont.defaultFontSize) -> UIFont? {
return UIFont(name: "\(fontFamily)-Normal", size: size)
}
}
class var Lato: CustomFont {
return CustomFont(fontFamily: "Lato")
}
class var Helvetica: CustomFont {
return CustomFont(fontFamily: "Helvetica")
}
class var ComicSans: CustomFont {
return CustomFont(fontFamily: "ComicSans")
}
}
用法:
let font = UIFont.Lato.Normal() // Returns a Normal font with default font size
let font = UIFont.Lato.Bold(withSize: 18) // Returns a Bold font with custom size
