## Usage



GMStepper is available through [CocoaPods](http://cocoapods.org) and [Swift Package Manager](https://www.swift.org/package-manager/).



### Cocoapods



To install using Cocoapods, simply add the following lines to your Podfile:



```ruby

use_frameworks!

pod "GMStepper"

```



### Swift Package Manager



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"



## Setup



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.



## Properties

```swift

/// 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. Defaults to white.

var labelTextColor: UIColor = UIColor.whiteColor()



/// Text color of the middle label. Defaults to lighter blue.

/// Font of the middle label. Defaults to AvenirNext-Bold, 25.0 points in size.

var labelFont = UIFont(name: "AvenirNext-Bold", size: 25.0)



/// Corner radius of the middle label's layer. Defaults to 0.0.

var labelCornerRadius: CGFloat = 0.0



/// Corner radius of the stepper's layer. Defaults to 4.0.

var cornerRadius: CGFloat = 4.0



/// Border width of the stepper and middle label's layer. Defaults to 0.0.

var borderWidth: CGFloat = 0.0



/// Color of the border of the stepper and middle label's layer. Defaults to clear color.

var borderColor: UIColor = UIColor.clearColor()



/// Percentage of the middle label's width. Must be between 0 and 1. Defaults to 0.5. Be sure that it is wide enough to show the value.

var labelWidthWeight: CGFloat = 0.5



/// Color of the flashing animation on the buttons in case the value hit the limit.
