GMStepper is available through CocoaPods . To install it, simply add the following lines to your Podfile:
use_frameworks! pod "GMStepper" If you want to use storyboards, just drop a UIView into your storyboard and set its class toGMStepper. Then customize through the attributes inspector. Otherwise, you can write the code to initialize with frame and set the properties.
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. var showIntegerIfDoubleIsInteger: Bool = true /// Text on the left button. Be sure that it fits in the button. Defaults to "-". var leftButtonText: String = "-" /// Text on the right button. Be sure that it fits in the button. Defaults to "+". var rightButtonText: String = "+" /// Text color of the buttons. Defaults to white var buttonsTextColor: UIColor = UIColor.whiteColor() /// Background color of the buttons. Defaults to dark blue. var buttonsBackgroundColor: UIColor = UIColor(red:0.21, green:0.5, blue:0.74, alpha:1) /// Font of the buttons. Defaults to AvenirNext-Bold, 20.0 points in size. var buttonsFont = UIFont(name: "AvenirNext-Bold", size: 20.0) /// Text color of the middle label.
