If you want to retain the system font and make it bold:

Try
尝试
[infoLabel setFont:[UIFont fontWithName:@"Arial-BoldMT" size:16]];
It may also be worth checking if the font you're trying to use is available on device
检查您尝试使用的字体是否在设备上可用也可能值得

Using the GUI in Xcode select the label then go to the Attributes Inspector. One of the options is Font. Click on the font icon (not the up-down arrows). In the popup that appears expand the Font ComboxBox. Under the Bold System section choose Regular.
使用 Xcode 中的 GUI 选择标签，然后转到 Attributes Inspector。选项之一是字体。单击字体图标（而不是上下箭头）。在出现的弹出窗口中展开字体 ComboxBox。在粗体系统部分下选择常规。

For swift users this should work:
对于快速用户，这应该有效：
myLabel.font = UIFont.boldSystemFont(ofSize: 12.0)
or if you'd like to use a different font:
或者如果您想使用不同的字体：
myLabel.font = UIFont(name:"HelveticaNeue-Bold", size: 12.0)

Where possible I would suggest using dynamic font sizes to provide the best possible accessibility to your users.
在可能的情况下，我建议使用动态字体大小来为您的用户提供最佳的可访问性。
You can make a label use a system dynamic font and set it to have bold text by doing the following:
您可以通过执行以下操作使标签使用系统动态字体并将其设置为粗体文本：
exampleLabel.font = UIFont.preferredFont(forTextStyle: .body, compatibleWith: UITraitCollection(legibilityWeight: .bold))

You can set the stroke with a negative value to make a bold effect if you don't have the bold variation of your custom font. See here:
如果您没有自定义字体的粗体变体，您可以将描边设置为负值以产生粗体效果。看这里：
