HMSegmentedControl is a customizable alternative to UISegmentedControl for iOS applications. It offers a drop-in replacement with additional features and styling options, allowing developers to create more visually appealing and interactive segmented controls.

Pros

• Highly customizable appearance and behavior
• Supports both text and images for segments
• Smooth animations for selection changes
• Compatible with iOS 7.0 and later

Cons

• Limited documentation and examples
• Not actively maintained (last update was in 2019)
• May require additional work to integrate with SwiftUI
• Some reported issues with Auto Layout constraints

Code Examples

Creating a basic segmented control:

let segmentedControl = HMSegmentedControl(sectionTitles: ["One", "Two", "Three"])
segmentedControl.frame = CGRect(x: 10, y: 10, width: 300, height: 40)
view.addSubview(segmentedControl)

Customizing appearance:

segmentedControl.selectedSegmentIndex = 1
segmentedControl.backgroundColor = .lightGray
segmentedControl.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.black]
segmentedControl.selectedTitleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
segmentedControl.selectionIndicatorColor = .blue

Adding a selection callback:

segmentedControl.indexChangeBlock = { index in
    print("Selected segment index: \(index)")
}

Getting Started

1. Add HMSegmentedControl to your project:

   • CocoaPods: Add pod 'HMSegmentedControl' to your Podfile
   • Manual: Copy the HMSegmentedControl.h and HMSegmentedControl.m files to your project

2. Import the header in your view controller:

   import HMSegmentedControl
   

3. Create and customize an instance of HMSegmentedControl:

   let segmentedControl = HMSegmentedControl(sectionTitles: ["Option 1", "Option 2", "Option 3"])
   segmentedControl.frame = CGRect(x: 10, y: 10, width: 300, height: 40)
   segmentedControl.selectedSegmentIndex = 0
   segmentedControl.backgroundColor = .lightGray
   segmentedControl.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.black]
   segmentedControl.selectedTitleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
   segmentedControl.selectionIndicatorColor = .blue
   view.addSubview(segmentedControl)
   

4. Implement the selection callback:

   segmentedControl.indexChangeBlock = { index in
       // Handle segment selection
   }
