Is there a medium weight font between -systemFontOfSize: and -boldSystemFontOfSize:?
提问by Proud Member
-systemFontOfSize is too thin, and boldSystemFontOfSize too thick. I need something inbetween.
-systemFontOfSize 太细，而 boldSystemFontOfSize 太粗。我需要介于两者之间的东西。
When I create a UIFont like this:
当我创建这样的 UIFont 时：
[UIFont boldSystemFontOfSize:14];
then the debugger prints this font info:
然后调试器打印此字体信息：
font-family: ".Helvetica NeueUI"; font-weight: bold; font-style: normal; font-size: 14px
字体系列：“.Helvetica NeueUI”；字体粗细：粗体；字体样式：正常；字体大小：14px
Sometimes fonts have a medium font weight. How can I create a font of this type but with a medium weight?
有时字体具有中等字体粗细。如何创建这种类型但中等重量的字体？

Calling NSLog(@"%@", [UIFont fontNamesForFamilyName:@"Helvetica Neue"]);prints all available font styles for Helvetica Neue, among them is HelveticaNeue-Mediumwhich sounds like the one you want:
调用NSLog(@"%@", [UIFont fontNamesForFamilyName:@"Helvetica Neue"]);打印 Helvetica Neue 的所有可用字体样式，HelveticaNeue-Medium其中听起来像您想要的字体样式：
UIFont *font = [UIFont fontWithName:@"HelveticaNeue-Medium" size:14.0f];
If you want to make sure that the font also changes when the system font changes (eg. like it did with retina devices from Helvetica to Helvetica Neue) you could first get the system font and then take its familyNameand pointSizeto retrieve one with medium weight using + fontNamesForFamilyNameand then + fontWithName:size:
如果您想确保在系统字体更改时字体也会更改（例如，就像使用从 Helvetica 到 Helvetica Neue 的 Retina 设备所做的那样），您可以先获取系统字体，然后使用它familyName并pointSize检索中等重量的字体+ fontNamesForFamilyName进而+ fontWithName:size:

UIFont.systemFont(ofSize: 14, weight: UIFontWeightMedium)

With Swift 4 or 5, add this extension :
使用 Swift 4 或 5，添加此扩展：
extension UIFont {
class func mediumSystemFont(ofSize pointSize: CGFloat) -> UIFont {
return self.systemFont(ofSize: pointSize, weight: .medium)
}
}
Then :
然后 ：
myLabel.font = UIFont.mediumSystemFont(ofSize: 16)
Same principle works with .semibold, .black, etc, check UIFont.Weight
同样的原则也适用与.semibold，.black等，检查UIFont.Weight

Swift 2.3 and not changing the font size:
Swift 2.3 并且不改变字体大小：
extension UIFont {
var mediumFont: UIFont {
return UIFont.systemFontOfSize(self.pointSize, weight: UIFontWeightMedium)
}
}
Use with:

titleLabel.font = titleLabel.font.mediumFont
