How does CategorySliderView compare to UISegmentedControl?

CategorySliderView offers more flexibility with custom views and dual orientations, but UISegmentedControl provides native iOS styling and accessibility out of the box. Use CategorySliderView for unique designs and UISegmentedControl for standard interfaces.

How to add a background image to CategorySliderView?

Set the backgroundImage property to a UIImage object after initialization. For example, use sliderView.backgroundImage = [UIImage imageNamed:@"background"]; to apply a custom background as mentioned in the optional properties.

Can I use CategorySliderView with Interface Builder?

The usage examples are programmatic, and there's no mention of IBInspectable or IBDesignable support. You might need to set it up in code or create custom integrations for visual design workflows.

How to handle selection events in CategorySliderView?

Use the categorySelectionBlock during initialization to define a callback. In the block, access the selected categoryView and index to update UI or trigger actions, as shown in the basic usage snippet.

Is CategorySliderView accessible for users with disabilities?

The README doesn't specify accessibility features. You'll need to manually set accessibility properties like accessibilityLabel on the category views to ensure compatibility with assistive technologies like VoiceOver.

How to implement vertical scrolling with CategorySliderView?

Initialize the slider with the desired orientation; it supports vertical layouts by default. Adjust the frame or constraints for vertical placement in your view hierarchy based on the sliderHeight parameter.

Pros & Cons

Pros

Unrestricted View Usage

Allows any UIView subclass as category items, enabling developers to use labels, images, or custom views for maximum design freedom, as shown in the usage example with UILabel.

Orientation Flexibility

Supports both horizontal and vertical layouts, making it adaptable to various app designs and user interface flows without extra configuration.

Provides methods like addCategoryView to dynamically add or remove category views programmatically, allowing updates based on app state or data changes.

Automatic Scrolling and Selection

Includes optional properties shouldAutoScrollSlider and shouldAutoSelectScrolledCategory for auto-scroll to closest category and selection, simplifying user interaction.

Cons

High Customization Overhead

Requires developers to manually style and configure each category view, which can be time-consuming compared to pre-styled components like UISegmentedControl.

Limited Advanced Features

Missing built-in support for gestures beyond dragging, complex animations, and comprehensive accessibility features, as not mentioned in the README.

Sparse Documentation
