SVPinView

SVPinView is a light-weight customisable library used for accepting pin numbers or one-time passwords.

Getting Started

An example project is included for demonstrating the functionality of SVPinView.

Installation

CocoaPods

Add the following line to your Podfile:

pod 'SVPinView', '~> 1.0'

Then run the following in the same directory as your Podfile:

pod install

Manual

Clone the repo and drag files from SVPinView/Source folder into your Xcode project.

Usage

Storyboard

Code

pinView.pinLength = 5
pinView.secureCharacter = "\u{25CF}"
pinView.interSpace = 5
pinView.textColor = UIColor.black
pinView.borderLineColor = UIColor.black
pinView.borderLineThickness = 1
pinView.shouldSecureText = true
pinView.style = .box

pinView.font = UIFont.systemFont(ofSize: 15)
pinView.keyboardType = .phonePad
pinView.pinIinputAccessoryView = UIView()
pinView.placeholder = "******"
pinView.becomeFirstResponderAtIndex = 0

The becomeFirstResponderAtIndex property sets the pinField at the specified index as the first responder.

Styles

enum SVPinViewStyle : Int {
  case none = 0
  case underline
  case box
}

There are two inbuilt styes; underline & box. However, the fieldBackgroundColor & fieldCornerRadius properties can be used to create custom styles.

pinView.style = .none
pinView.fieldBackgroundColor = UIColor.white
pinView.fieldCornerRadius = 0

Methods

• getPin(): Returns the entered pin as a String. If the method is called when the pin entry is incomplete, it returns an empty String for validation.
• pastePin(): Takes a String as an argument and enters it into the pinView. Useful for showing default values or for pasting from clipboard. Long-press on the pin field will also allow pasting from the clipboard.
• clearPin(): Clears the entered pin.

Callbacks

SVPinView has a didFinish callback, which gets executed after the pin has been entered. This is useful when a network call has to be made or for navigating to a different ViewController after the pin has been entered.

pinView.didFinishCallback = { pin in
  print("The pin entered is \(pin)")
}

Requirements

• iOS 9.0 +
• Xcode 8.0 +
