Question

我想在iOS上发布NetService，我创建这样的NetService：

    import UIKit

override func viewDidLoad() {
    super.viewDidLoad()
    let dimensions = (width: 200, height: 300)
    let control = TestHarness(frame: CGRect(x: dimensions.width / 2, y: dimensions.height / 2, width: dimensions.width, height: dimensions.height))

    control.JobTitle = "Developer b2.0" // << -- No overlap in simulator

    let contentView = UIView(frame: control.frame.insetBy(dx: -100, dy: -100))
    contentView.backgroundColor = #colorLiteral(red: 0.3098039329, green: 0.01568627544, blue: 0.1294117719, alpha: 1)
    contentView.addSubview(control)
    view.addSubview(contentView)
}

然后我发布它，到目前为止，它可以正常工作。但是当我将类型更改为else { alert("name : "+name+"\ncakedonuts : "+cakedonuts+"\nglazeddonuts : "+glazeddonuts); return true; }时，我得到了以下错误信息：

let netService = NetService(domain: "local.", type: "_demo._tcp.", name: "demo", port: 0)

为什么我们不能在iOS上使用UDP类型发布NetService？
