To dismiss the ProgressHUD:

要关闭 ProgressHUD：

You can also try this approach which will keep the other activity running in the background allowing the UI to remain responsive, providing users with a better experience. This is the intended/recommended approach for using the MBProgressHUD.

您也可以尝试这种方法，它可以让其他 Activity 在后台运行，从而让 UI 保持响应，为用户提供更好的体验。这是使用 MBProgressHUD 的预期/推荐方法。

let progressHUD = MBProgressHUD.showHUDAddedTo(self.view, animated: true)
progressHUD.labelText = "Loading..."

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_LOW, 0)) {

    // ...Run some task in the background here...

    dispatch_async(dispatch_get_main_queue()) {
        progressHUD.hide(true)

        // ...Run something once we're done with the background task...
    }
}

Swift 3 extensions

斯威夫特 3 扩展

import Foundation
import MBProgressHUD
import QuartzCore

extension UITableViewController {
    func showHudForTable(_ message: String) {
        let hud = MBProgressHUD.showAdded(to: self.view, animated: true)
        hud.label.text = message
        hud.isUserInteractionEnabled = false
        hud.layer.zPosition = 2
        self.tableView.layer.zPosition = 1
    }
}

extension UIViewController {
    func showHud(_ message: String) {
        let hud = MBProgressHUD.showAdded(to: self.view, animated: true)
        hud.label.text = message
        hud.isUserInteractionEnabled = false
    }

    func hideHUD() {
        MBProgressHUD.hide(for: self.view, animated: true)
    }
}

Create Extension to Easy to use and throughout application

创建易于使用和整个应用程序的扩展

extension UIViewController {

    func showHUD(progressLabel:String){
        DispatchQueue.main.async{
            let progressHUD = MBProgressHUD.showAdded(to: self.view, animated: true)
            progressHUD.label.text = progressLabel
        }
    }

    func dismissHUD(isAnimated:Bool) {
        DispatchQueue.main.async{
            MBProgressHUD.hide(for: self.view, animated: isAnimated)
        }
    }
}

USAGE:

用法：

1. SHOW- self.showHUD(progressLabel: "Loading...")

1. 显示- self.showHUD(progressLabel: "Loading...")

2. HIDE- self.dismissHUD(isAnimated: true)

2.隐藏- self.dismissHUD(isAnimated: true)

Go through the below code

通过下面的代码

class ViewController: UIViewController, MBProgressHUDDelegate {
    var hud : MBProgressHUD = MBProgressHUD()
    func fetchData() {
        hud = MBProgressHUD.showHUDAddedTo(self.view, animated: true)
        hud.mode = MBProgressHUDModeIndeterminate
        hud.labelText = "Loading"
    }
}

If you want to dismiss the HUD

如果您想关闭 HUD

MBProgressHUD.hideHUDForView(self.view, animated: true)

回答by Bharathi Devarasu

Use the below code to render MBProgressHUD and after some action completed hide it as described.

使用以下代码呈现 MBProgressHUD，并在完成某些操作后按描述隐藏它。

let spinnerActivity = MBProgressHUD.showHUDAddedTo(self.view, animated: true);

spinnerActivity.label.text = "Loading";
spinnerActivity.detailsLabel.text = "Please Wait!!";
spinnerActivity.userInteractionEnabled = false;

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_LOW, 0))
    {
        // Add some background task like image download, wesite loading. 

        dispatch_async(dispatch_get_main_queue())
            {
                spinnerActivity.hideAnimated(true);
        }


    }

Try it with Swift 3:

用 Swift 3 试试：

func showLoadingHUD(to_view: UIView) {
    let hud = MBProgressHUD.showAdded(to: to_view, animated: true)
    hud.label.text = "Loading..."
}

func hideLoadingHUD(for_view: UIView) {
    MBProgressHUD.hideAllHUDs(for: for_view, animated: true)
}

If Swift compiler warning: hideAllHUDs is deprecated. We should store references when using more than one HUD per view

如果 Swift 编译器警告： hideAllHUDs is deprecated. We should store references when using more than one HUD per view

Use:

用：

func hideLoadingHUD(for_view: UIView) {
    MBProgressHUD.hide(for: for_view, animated: true)
}

step 1 : Download "MBProgressHUD.h" and "MBProgressHUD.m" file and Add both file into your project. it will ask you to Bridging for Objective C files. if you already done bridging then it won't ask.

第 1 步：下载“MBProgressHUD.h”和“MBProgressHUD.m”文件并将这两个文件添加到您的项目中。它会要求您桥接 Objective C 文件。如果你已经完成了桥接，那么它就不会问了。

step 2 : In Bridging File import MBProgressHUD "import MBProgressHUD.h"

第 2 步：在桥接文件中导入 MBProgressHUD "import MBProgressHUD.h"

step 3 : use below code to show progress hud or hide hud.

第 3 步：使用以下代码显示进度 hud 或隐藏 hud。

for Show

用于展示

DispatchQueue.main.async {
    MBProgressHUD.showAdded(to: self.view, animated: true)
}

for hide

为了隐藏

DispatchQueue.main.async {
    MBProgressHUD.hide(for: self.view, animated: true)
}

I solved it like this:

我是这样解决的：

import UIKit

class Loader: NSObject {

    class func show(message:String = "Processing...", delegate: UIViewController) {
        var load : MBProgressHUD = MBProgressHUD()
        load = MBProgressHUD.showHUDAddedTo(delegate.view, animated: true)
        load.mode = MBProgressHUDMode.Indeterminate

        if message.length > 0 {
            load.labelText = message;
        }

        UIApplication.sharedApplication().networkActivityIndicatorVisible = true

    }

class func hide(delegate:UIViewController) {
    MBProgressHUD.hideHUDForView(delegate.view, animated: true)
        UIApplication.sharedApplication().networkActivityIndicatorVisible = false
    }
}
