Swift:设置 NSProgressIndicator的进度

Question

我尝试使用以下方法设置自己的NSProgressIndicator。

class ProgressViewController : NSViewController 
{
    override func loadView()
    {
        let view = NSView(frame: NSMakeRect(0,0,300,120))
        view.wantsLayer = true
        view.layer?.borderWidth = 0
        self.view = view
        let text = NSTextField(frame: NSRect(x: 20, y: 45, width: 260, height: 20))
        text.drawsBackground = true
        text.isBordered = false
        text.backgroundColor = NSColor.controlColor
        text.isEditable = false
        self.view.addSubview(text)
        text.stringValue = "Progress Text"
        let indicator = NSProgressIndicator(frame: NSRect(x: 20, y: 20, width: 260, height: 20))
        indicator.minValue = 0.0
        indicator.maxValue = 100.0
        indicator.doubleValue = 33.0
        self.view.addSubview(indicator)
    }
}

我的问题是指标总是显示完整。我错过了一个技巧吗？

默认样式不确定。将其设置为 false，一切应该没问题：

indicator.isIndeterminate = false
