Using MBProgressHUD in iOS

It looks like you’re asking about how to use the MBProgressHUD library in an iOS project, specifically version 0.9.1, via a Podfile in CocoaPods. Let me guide you through the process step-by-step.

What is MBProgressHUD?

MBProgressHUD is a popular third-party library for iOS that provides an easy way to display a HUD (Heads-Up Display) with activity indicators, progress bars, or custom views, typically used to show loading states or brief messages.

Steps to Use `pod 'MBProgressHUD', '0.9.1'`

1. Install CocoaPods (if not already installed)

CocoaPods is a dependency manager for iOS projects. If you don’t have it installed, run this command in your terminal:

sudo gem install cocoapods

2. Set Up a Podfile

Navigate to your Xcode project directory in the terminal:
```
cd /path/to/your/project
```
If you don’t already have a Podfile, create one by running:
```
pod init
```
Open the Podfile in a text editor (e.g., nano Podfile or open Podfile).

3. Add MBProgressHUD to Your Podfile

In your Podfile, add the line for MBProgressHUD version 0.9.1 within the target block for your app. It should look something like this:

platform :ios, '9.0'  # Specify your deployment target

target 'YourAppName' do
  use_frameworks!
  pod 'MBProgressHUD', '0.9.1'
end

Replace 'YourAppName' with the actual name of your Xcode target.
The platform :ios, '9.0' line sets the minimum iOS version; adjust it based on your project’s needs.

4. Install the Pod

Save the Podfile and run this command in the terminal:
```
pod install
```
This downloads and integrates MBProgressHUD version 0.9.1 into your project. If successful, you’ll see output confirming the installation.

5. Open the Workspace

After installation, close your Xcode project (if open) and open the newly created .xcworkspace file (e.g., YourAppName.xcworkspace) instead of the .xcodeproj file. CocoaPods generates this workspace to manage dependencies.

6. Using MBProgressHUD in Your Code

Swift: Import the module and use it in your code:

import MBProgressHUD

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
          
        // Show a simple HUD with a loading indicator
        let hud = MBProgressHUD.showAdded(to: self.view, animated: true)
        hud.label.text = "Loading..."
          
        // Hide it after some time (e.g., 2 seconds)
        DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
            hud.hide(animated: true)
        }
    }
}

Objective-C: Import the header and use it:

#import <MBProgressHUD/MBProgressHUD.h>

@interface ViewController ()
@end

@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
      
    // Show a simple HUD with a loading indicator
    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
    hud.label.text = @"Loading...";
      
    // Hide it after some time (e.g., 2 seconds)
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 2 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
        [hud hideAnimated:YES];
    });
}
@end

7. Common MBProgressHUD Features

Basic HUD: As shown above, display a spinning indicator with optional text.

Custom Text Only:

let hud = MBProgressHUD.showAdded(to: view, animated: true)
hud.mode = .text
hud.label.text = "Done!"
hud.hide(animated: true, afterDelay: 1.5)

Progress Bar:

let hud = MBProgressHUD.showAdded(to: view, animated: true)
hud.mode = .determinate
hud.progress = 0.5 // 50% progress

Notes

Version 0.9.1: This is an older version (released around 2015). The latest version as of March 2025 is much newer (e.g., 1.2.0 or higher). To use the latest, simply write pod 'MBProgressHUD' without a version number. Consider updating unless you specifically need 0.9.1 for compatibility.
Documentation: Check the MBProgressHUD GitHub page for more options and examples. Version 0.9.1 might have fewer features than modern releases.
