A stepper with a sliding label in the middle. Pan the label or tap the buttons. Check out the tutorial, How to Build a Custom Stepper - Part 1.
GMStepper is available through CocoaPods and Swift Package Manager.
To install using Cocoapods, simply add the following lines to your Podfile:
use_frameworks!
pod "GMStepper"To install using Swift Package Manager in XCode:
- File > Swift Packages > Add Package Dependency
- Add https://github.com/gmertk/GMStepper
- Select "Up to Next Major" with "2.3"
If you want to use storyboards, just drop a UIView into your storyboard and set its class to GMStepper. Then customize through the attributes inspector. Otherwise, you can write the code to initialize with frame and set the properties.
/// Current value of the stepper. Defaults to 0.
var value: Double = 0
/// Minimum value. Must be less than maximumValue. Defaults to 0.
var minimumValue: Double = 0
/// Maximum value. Must be more than minimumValue. Defaults to 100.
var maximumValue: Double = 100
/// Step/Increment value as in UIStepper. Defaults to 1.
var stepValue: Double = 1
/// The same as UIStepper's autorepeat. If true, holding on the buttons or keeping the pan gesture alters the value repeatedly. Defaults to true.
var autorepeat: Bool = true
/// If the value is integer, it is shown without floating point.
