如何创建带有阴影的标签文本？

Question

I'm trying to create a label text with a shadow created automatically by the system. In iOS I know that you can use an Attributed style for the label, but in OS XI can't find this option. Could you help?

You can do that with Core Animation (aka CALayer ). Views in iOS are layer-backed by default, but NSView on Mac OS X are much older and requires you to turn on layer manually.

The easiest way is to go to the View Effects Inspector ( Cmd + Alt + 8 ):

If you want to add the shadow programmatically:

override func awakeFromNib() {
    let shadow = NSShadow()
    shadow.shadowOffset = NSMakeSize(5,5)
    shadow.shadowBlurRadius = 5
    shadow.shadowColor = NSColor.blackColor()

    myLabel.superview?.wantsLayer = true
    myLabel.shadow = shadow
}
