Getting Started
To get started with ninaselectionview in your iOS project, follow these steps:
- Install ninaselectionview using CocoaPods by adding the following line to your Podfile:
pod 'ninaselectionview'
- In your project’s directory, run
pod install
to install the dependency - Import the ninaselectionview module in your code file:
import ninaselectionview
- Create an instance of the NinaSelectionView class and add it to your view hierarchy
- Configure the selection view properties and provide the necessary data
- Implement the delegate methods to handle selection events
Usage
To use ninaselectionview in your iOS application, you’ll typically follow these steps:
Step 1: Initialization
First, create an instance of the NinaSelectionView class. This will serve as the main view for the selection interface.
“`swift
let selectionView = NinaSelectionView(frame: CGRect(x: 0, y: 0, width: 300, height: 400))
“`
Step 2: Configure Appearance
Customize the appearance and layout of the selection view according to your needs. You can modify properties such as background color, item spacing, selection style, and more.
“`swift
selectionView.backgroundColor = .white
selectionView.itemSpacing = 10
selectionView.selectionStyle = .transparent
“`
Step 3: Provide Data
Populate the selection view with the necessary data. You’ll need to create an array of selectable items, each represented by a data model object conforming to the NinaSelectable protocol.
“`swift
let items: [NinaSelectable] = [
MySelectableItem(title: “Item 1”),
MySelectableItem(title: “Item 2”),
MySelectableItem(title: “Item 3”)
]
selectionView.setItems(items)
“`
Step 4: Handle Selection Events
Implement the delegate methods of the NinaSelectionViewDelegate protocol to handle selection events. You can perform custom actions or update your application’s logic based on the user’s selections.
“`swift
extension ViewController: NinaSelectionViewDelegate {
func ninaSelectionView(_ selectionView: NinaSelectionView, didSelectItem item: NinaSelectable, at index: Int) {
// Handle item selection
}
func ninaSelectionView(_ selectionView: NinaSelectionView, didDeselectItem item: NinaSelectable, at index: Int) {
// Handle item deselection
}
}
“`
Additional Customization Options
Custom Item Views
You can provide custom item views for each selectable item by implementing the NinaSelectable protocol and creating a custom view class or nib file.
“`swift
class MySelectableItemView: UIView {
// Customize the appearance of your custom item view
}
class MySelectableItem: NinaSelectable {
var title: String
var view: UIView {
return MySelectableItemView(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
}
init(title: String) {
self.title = title
}
}
“`
Additional Configuration Properties
Here are some additional properties you can configure on the NinaSelectionView:
itemSpacing
: Sets the spacing between selectable items.selectionStyle
: Defines the visual style for selected items.allowsMultipleSelection
: Determines whether multiple items can be selected simultaneously.selectionLimit
: Limits the maximum number of selectable items in multi-selection mode.delegate
: Sets the object to receive selection events.
