iPhone 字符间距
Is there a way to add character spacing in UILabel?
I found some examples like:
How to change an UILabel/UIFont's letter spacing?
But it's hard to believe that there isn't a easier way.

除了自定义 Quartz 绘图之外，没有其他方法可以实现您想要的目标，UILabel 不够灵活。然而，其他人已经接受了挑战，例如 OHAttributedLabel 允许您设置 NSAttributedString 作为标签的文本。尝试NSKernAttributeName，它会修改字偶距，但我从未在 iOS 上尝试过，只在 OS X 上尝试过。
There is no other to achieve what you want than doing custom Quartz drawing, UILabel is not flexible enough. However, other people have taken on the challenge, there is for example OHAttributedLabel which allows you to set an NSAttributedString as the label's text. Try the NSKernAttributeName, it modifies kerning but I've never tried this on iOS, only OS X.
在IB中，您可以点击调整以适应和（以字体大小），并在布局中将行数设置为“0”，以达到接近您的要求。（或您也可以通过代码来完成）。
In IB you can click on Adjust to fit and (In font size), and set lines to '0' in in layout, to achieve near to your requirement.(or you can do it by code too).
