[myView setFont:[UIFont systemFontOfSize:12]];
or
或者
[myView setFont:[UIFont boldSystemFontOfSize:12]];
or for font family
或字体系列
[myView setFont:[UIFont fontWithName:@"Helvetica" size:12]];

If your UILabel's font is defined in IBstoryboardand you just want to increase size then this will work, worked for me ;)
如果您UILabel的字体定义为IBstoryboard并且您只想增加大小，那么这将起作用，对我有用;)
[_label setFont: [_label.font fontWithSize: sizeYouWant]];
Or
或者
[self.label setFont: [self.label.font fontWithSize: sizeYouWant]];
Another method as others says also worked:
其他人所说的另一种方法也有效：
[_label setFont:[UIFont systemFontOfSize:13.0]];

Remember that the user can globally set how large they want their text to be, so you shouldn't use a fixed font size like "12". Use the following fonts:
请记住，用户可以全局设置他们希望文本的大小，因此您不应该使用像“12”这样的固定字体大小。使用以下字体：
[UIFont preferredFontForTextStyle:UIFontTextStyleHeadline]
[UIFont preferredFontForTextStyle:UIFontTextStyleBody]
[UIFont preferredFontForTextStyle:UIFontTextStyleSubheadline]
[UIFont preferredFontForTextStyle:UIFontTextStyleFootnote]
[UIFont preferredFontForTextStyle:UIFontTextStyleCaption1]
[UIFont preferredFontForTextStyle:UIFontTextStyleCaption2]
I think the default for UILabel is Caption1, the others will be bigger or smaller. And they will adapt if the user wants big text or small text on his or her device. (Font size 12 might actually bigger than the normal label size if the user picked a very small size).
我认为 UILabel 的默认值是 Caption1，其他的会更大或更小。如果用户想要在他或她的设备上使用大文本或小文本，它们会进行调整。（如果用户选择了一个非常小的尺寸，12 号字体实际上可能比正常标签尺寸大）。

Swift 4 and above.
Swift 4 及以上。
You may also try it.
你也可以试试。
label.font = UIFont.systemFont(ofSize: 10)
