How to Change Font Style in Swift
提问by Collin O.
I'm trying to figure out how to change the style of a font to "Thin". Does anyone know how to do this?
我想弄清楚如何将字体的样式更改为“细”。有谁知道如何做到这一点？
Here's my best try, but it doesn't work:
这是我最好的尝试，但它不起作用：
m.font = UIFont(name: "Apple SD Gothic Neo", style: "Thin", size: 8.0)
回答by Caleb Kleveter
The way I have seen it is AppleSDGothicNeo-Thin, No spaces, and a dash style. So your code would be
我所看到的方式是AppleSDGothicNeo-Thin，没有空格，并且是破折号样式。所以你的代码将是
m.font = UIFont(name: "AppleSDGothicNeo-Thin", size: 8.0)

I have come to understand why you use the font this way.
我开始理解你为什么这样使用字体。
If you add a custom font to your project, it has a name of "SuperAwesomeFont-Light.ttf". So it makes sense that you just use the file name for the name of the font.
如果您向项目添加自定义字体，它的名称为“SuperAwesomeFont-Light.ttf”。因此，您只使用文件名作为字体名称是有道理的。

You have trouble with font name.
字体名称有问题。
At first find out proper name of the font and than use it.
首先找出字体的正确名称，然后使用它。
Firstly print all names of them. And then use. Code example show all installed fonts of the application.
首先打印它们的所有名称。然后使用。代码示例显示应用程序的所有已安装字体。
func printFonts() {
let fontFamilyNames = UIFont.familyNames()
for familyName in fontFamilyNames {
print("------------------------------")
print("Font Family Name = [\(familyName)]")
let names = UIFont.fontNamesForFamilyName(familyName)
print("Font Names = [\(names)]")
}
}
And after you detect Font you can set this like :
在检测到 Font 后，您可以将其设置为：
m.font = UIFont(name: "AppleSDGothicNeo-Thin", size: 8.0)

This might work:
这可能有效：
let font = UIFont(name: "HelveticaNeue-Thin", size: 16.0)!

Put this in playground to get all correct names of the fonts, available (updated for Swift 3.0 on basis of oleg)
把它放在操场上以获得所有正确的字体名称，可用（在 oleg 的基础上为 Swift 3.0 更新）
//: Playground - noun: a place where people can play
import UIKit
func printFonts() {
let fontFamilyNames = UIFont.familyNames
for familyName in fontFamilyNames {
print("------------------------------")
print("Font Family Name = [\(familyName)]")
let names = UIFont.fontNames(forFamilyName: familyName)
print("Font Names = [\(names)]")
}
}
printFonts()

lblDes.font = UIFont (name: "HelveticaNeue-UltraLight", size: 14.0)
lblDes.font = UIFont（名称：“HelveticaNeue-UltraLight”，大小：14.0）

let myLabel = UILabel(frame: CGRect(x: 0, y: 0, width: yourWidth, height: yourHeight))
myLabel.text = "Your Text"
myLabel.font = UIFont(name: "Name of your font", size: 18)
self.view.addSubview(emptyMessageLabel)
myLabel.translatesAutoresizingMaskIntoConstraints = false
myLabel.centerYAnchor.constraint(equalTo: self.view.centerYAnchor).isActive = true
myLabel.centerXAnchor.constraint(equalTo: self.view.centerXAnchor).isActive = true
