如果这不起作用，那么使用下面的代码来定义你的var：
Color:NSColor=NSColor(hexString:"ff8942",alpha:0.5)// Short handlingletshortColorWithHex:NSColor=NSColor(hexString:"fff")// From a real hex value (an `Int`)// With hashletcolor:NSColor=NSColor(hex:0xff8942)// Without hash, with alphaletsecondColor:NSColor=NSColor(hex:0xff8942,alpha:...
With rgba, the alpha dimension ranges from 0 to 1. However, with 8-digit hex color codes, the alpha dimension ranges from 0 to 255 – and therefore when converting back and forth between rgba and 8-digit hex color codes, you’ll have to scale up or down by 255 accordingly. We can ...
