How To Use

The library is all the Swift files in the Source folder. You can just drag and drop those files into your project or use the cocoapod pod 'TDLikertScaleSelectorView'.

The TDLikertScaleSelectorView class is the main UIView class containing the answer options / selections. You can add the UIView through code as shown below, or through Interface Builder. Implement a concrete class or struct of the TDSelectionBuildConfig protocol to skin / theme the controls to your needs. Clone the entire project to see demo use - the main storyboard and viewcontroller shows how to use the library.

import TDLikertScaleSelectorView

struct MyBuildConfig: TDSelectionBuildConfig {
    var font: UIFont? = UIFont.systemFont(ofSize: 15)
    var textColor: UIColor?  = UIColor.purple
    var backgroundColorNormal: UIColor? = UIColor.clear
    var backgroundColorHighlighted: UIColor? = UIColor.lightGray
    var backgroundColorSelected: UIColor? = UIColor.red
    var backgroundColorHighlightedSelected: UIColor? = UIColor.lightGray
    var borderColor: UIColor? = .purple
    var borderWidth: CGFloat? = 2.0
    var buttonRadius: CGFloat? = 22
    var lineColor: UIColor? = .purple
}

var config = MyBuildConfig()
if let likertView = TDLikertScaleSelectorView(withConfig: config, frame: CGRect.zero) {
    likertView.delegate = self
    likertView.tag = 1 // could be question number
    self.view.addSubview(likertView)
}

extension ViewController: TDLikertScaleDelegate {
    func didSelect(category cat: TDSelectionCategory, tag: Int) {
        print("Question with tag \(tag) has answer \(cat.localizedName)")
    }
}
