iOS- MBProgressHUD bezelView变为透明

Question

我正在使用MBProgressHUD，并希望将bezelView设为br透明。

import UIKit
import MBProgressHUD

class ProgressBarManager {
   func showProgressBar() {
    guard let testView = UIApplication.shared.windows.last else { return }        
    let hud = MBProgressHUD.showAdded(to: testView, animated: true)

    hud.bezelView.layer.cornerRadius = 5
    hud.bezelView.backgroundColor = .clear
    hud.backgroundView.style = .solidColor
    hud.backgroundView.color = UIColor(white: 0, alpha: 0.3)

 }
}

但是bezelView仍然显示：

是否可以隐藏它？

Answer 1

let hud = MBProgressHUD.showAdded(to: self.view, animated: true)
hud.backgroundColor = UIColor.clear
hud.bezelView.backgroundColor = UIColor.clear
hud.bezelView.color = UIColor.clear
hud.bezelView.style = .solidColor
