你可以这样做
Label.layer.borderColor = [UIColor whiteColor].CGColor;
Label.layer.borderWidth = 4.0;
before this you need to import a framework QuartzCore/QuartzCore.h

You can also try to subclass your label and override the drawRect: method to draw or a border or whatever you like:
您还可以尝试子类化您的标签并覆盖 drawRect: 方法以绘制或边框或您喜欢的任何内容：
- (void)drawRect:(CGRect)rect
{
[super drawRect:rect];
CGContextRef context = UIGraphicsGetCurrentContext();
[[UIColor blackColor] setStroke];
CGContextStrokeRect(context, self.bounds);
}

I'm not sure you can by default with UILabel. You might want to consider using a read-only (field.editing = NO) UITextFieldand setting it's borderStyle (which can be done programmatically using a UITextBorderStyle). That may be a little 'heavy' though. Another option may be to sub-class UILabelto draw your border.
我不确定默认情况下您可以使用UILabel. 您可能需要考虑使用只读 (field.editing = NO)UITextField并将其设置为 borderStyle （可以使用 a 以编程方式完成UITextBorderStyle）。不过，这可能有点“重”。另一种选择可能是子类UILabel来绘制您的边框。
Alternatively, and depending on your needs this may be better, use the backing CALayerand draw a border using it's borderColor and borderWidth properties.
或者，根据您的需要，这可能会更好，使用支持CALayer并使用其 borderColor 和 borderWidth 属性绘制边框。
